    Video encoding is the science of codifying the bits of data that make up a digital video recording into a unified whole according to a set of specific standards and parameters. If it sounds techy, it should. In simpler words, video encoding is the process of taking your original movie, as recorded by your camcorder, mobile phone or webcam, and preparing it for delivery in a digital format according to specific technical standards. This MasterNewMedia guide brings you everything you need to know about the key differences between major video file formats / containers and codecs.

    From .WMV to .MOV and from .AVI to .FLV, this guide presents the best information available online on what you need to know about the use and characteristics of the major video file formats, containers and relative codecs.

    When you video encode a clip, you are saving your video into a specific “format” much like you can do with a Word document or a digital image. A Word document can be encoded in .RTF or in .TXT, just like an image can be encoded in .JPG or .BMP formats.

    Obviously, different types of encodings are good for different applications and devices.

    Broadcasting, live streaming, burning to DVD and archiving all require different video encoding parameters while your computer browser, an iPhone and your gaming console have all different expectations when it comes to playing back video files. And this is why knowing a bit about video encoding, video file formats and containers is quite important if you intend to publish and distribute digital video.
    In the video universe it is easy to get lost, as the formats, codecs and file containers generate a universe of possibilities and variables that are initially not easy to understand.

    If you want to upload and publish a video on YouTube, for instance, you would have to choose specific encoding settings and file formats, whereas your choice would be different if your video clips are to burned on a DVD.

    As an online publisher you may already be familiar with some of these issues, but as new technologies like  HTML5 and  WebM are starting to make inroads, you are going to need to better understand the key differences and the pros and cons that such different formats entail for you.

    To help you achieve this goal, the MasterNewMedia research team has prepared a comprehensive guide to bring together all of the “fundamentals” you need to master to fully understand the basics of video encoding, specifically:

    • What is video encoding
    • Video file formats and containers
    • Comparison of video codecs
    • Encoding settings for Internet video publishing
    • Video publishing settings for YouTube

    In the next post we will introduce some Video Encoding Guides we found online.

    Apple shall introduce the final version of iOS 4.1 for iPhone and iPod touch (though probably not for iPad) soon.  Apple released the first beta for iOS 4.1 on July 14 and stuck to their every-two-weeks cycle for beta 2 on July 27 and beta 3 on August 3.

    What we know about iOS4.1 is that it includes a new, font-crazy version of Game Center, which was also included in the iOS 4 betas but removed for the general release, and FaceTime connections over email, which will be required for non-phone devices like iPod touch 4.

    It will also likely contain bug fixes for the proximity sensor, and hopefully performance fixes for iPhone 3G.

    Those features are certainly impressive, those fixes certainly much needed. But is that all we’ll get? There’s no way to know what Apple will do in the future, but we can look at what they’ve done with past iOS x.1 releases for clues…

    iOS 3.1 (iPhone 3.1)

    iOS 3.1, originally referred to as iPhone 3.1, was released on September 9, 2009following Apple’s It’s only rock and roll but we like it special music event. It fixed issues with iPhone 3G Wi-Fi and icon display. It also added:

    • Triple click Home for accessibility options
    • Voice control over Bluetooth
    • Remote passcode lock with Find my iPhone
    • Save MMS to camera roll
    • Event location in popup alert
    • Non-destructive video clip trimming
    • Tethered data usage stats
    • Fraud warnings toggle for Safari
    • iTunes account credit display
    • Top Grossing in App Store
    • Genius for apps
    • Genius mixes
    • Copy and paste in Phone and Contacts

    iOS 2.1 (iPhone 2.1)

    iOS 2.1, originally referred to as iPhone 2.1, was introduced on September 9, 2008 at Apple’s Let’s rock special music event and released on September 12, 2008. It fixed problems with call drops, battery life, backup times, email reliability, 3rd party app installation speeds, SMS performance, contact loading and search, “improved accuracy” of 3G bars (which have since been “corrected” again in iOS 4.0.1). Features included:

    • Screen shot added camera shutter sound
    • Load earlier SMS messages
    • SMS alert repeat
    • Disable Camera in Settings Restrictions
    • Option to wipe data after 10 failed passcode attempts
    • Genius playlist creation
    • Tap icon to pause/resume app install
    • App icons remain in place following on-device update

    Note: Unlike iOS 3, where iOS 3.2 was exclusive to iPad, there was an iOS 2.2 (iPhone 2.2) update for iPhone and iPod touch. iPhone 2.2 added Google Street View, Transit and Walking directions, the ability to turn off auto-correct, audio and video podcasts in the iTunes Store app, App Store “rate app on delete” (since removed in iOS 4), the return of Update All for apps, and a rejiggered Safari search bar.

    iOS 1.1 (iPhone 1.1)

    iOS 1.1 (iPhone 1.1) was originally shown off on the first generation iPod touch on September 14, 2007 during Apple’s The beat goes on special music event, but was released as iOS 1.1.1 (iPhone 1.1.1, or September ‘07 update) for iPhone on September 27. Added were:

    • iTunes Wi-Fi Music Store app
    • Louder speaker volume
    • Double click home to launch favorites or iPod controls
    • Double tap space bar for a period (.)
    • Landscape support for Mail attachments
    • Re-ordering for Stocks and Weather items
    • Apple Bluetooth headset (RIP) battery status
    • Disable roaming data
    • Additional passcode lock time settings
    • Adjustable alert volumes

    There was no iOS 1.2 (iPhone 1.2) update, but there was a significant iOS 1.1.3 (iPhone 1.1.3 or January ‘08) update shown off at Macworld on January 15, 2008 that added Mail, Maps, Stocks, Weather, and Notes to iPod touch (for a price), gave Google Maps the “locate me” function, introduced “jiggly mode” to re-arrange icons, added iTunes gift card redemption on-device, gave lyrics to music, let you add Web Clips to the home screen, enabled multi-person SMS, included Gmail as a default set up type, made the keyboard multitouch, and put chapters, language, etc. into movies.

    So what does this mean for iOS 4.1?

    Smaller version updates mean smaller feature additions. If you’re holding out hope for a brand new notification system you’ll probably have to wait for next March and the iOS 5 sneak preview event. If Game Center, and FaceTime moving beyond the iPhone, interest you, then you’ll probably have lots to be happy about. It’s always possible we’ll get “One more thing…” but looking back over previous iOS x.1 (iPhone x.1) updates, I’m not holding my breath. Too much.

    For those people who get confused about HDTV, 8 HDTV myths demystified is one excellent post which will help you better understand HDTV.

    It’s confusing to pick the right HDTV, especially when your favorite blue-shirted salesperson may be steering you in a certain direction in hopes of a bigger commission. Or maybe the rep is just misinformed. I’ll highlight some of the most prominent assertions made on the showroom floors of big-box retailers and explain the realities, along with tips and details for buying an HDTV, selecting the best content, hooking up the set at home, and more.

    Claim: “HD” signifies a specific standard of quality
    Status: False

    Though “HD” does stand for “high definition,” HDTVs come in several resolutions; and in any event, a set’s resolution doesn’t completely determine the exact image quality you’ll see on your screen. For one thing, screen sizes vary. Other factors affecting the picture include the transmission — over the air, via cable, by satellite or from the Internet — and the original source material.

    These variables help explain why you can get high-def content from Amazon, Hulu, iTunes, Netflix streaming, a Blu-ray disc and other sources, and yet encounter wildly different picture quality.

    The most familiar of the HD resolutions are 720p (consisting of a 1280-by-720-pixel frame) and 1080i (composed of 1920-by-1080-pixel images). The “p” stands for “progressive scan,” meaning that the set creates the image by continuously redrawing the frame, line by line. The “i” stands for “interlaced,” meaning that halves of the full frame are shown 60 times per second, but your eyes combine them into a full-frame image reproducing itself at a rate of 30 frames per second. At the same resolution, a progressive-format image looks better than an interlaced image.

    Over-the-air broadcast standards top out at 720p and 1080i, but you can obtain the full 1920-by-1080-pixel frame in 1080p from Blu-ray discs, certain Xbox 360 models and the PlayStation 3 units.

    Compression and bit rate are other factors in picture quality. A Blu-ray disc should look better than a cable TV feed of the same content at the same resolution, since the disc has more bandwidth than the cable broadcast.

    When choosing for picture quality, remember: 1080p is at the top, 720p and 1080i look similar, and anything below them won’t be as good.

    Claim: If you don’t buy a 1080p HDTV, you’re wasting your money
    Status: False

    In all likelihood, you want a 1080p HDTV — and you should be sure to get that resolution if your set has a diagonal screen size of 32 inches or greater, since you’ll be able to see the additional resolution on a big-screen from across the room. Furthermore, there’s no reason to avoid a 1080p HDTV if it doesn’t cost substantially more than sets with alternative resolutions, given that 1080p is becoming ubiquitous. If the difference is within $100, I recommend going for a 1080p set if your budget can handle it.

    But having said all that, I should warn you that you probably won’t see any improvement in picture quality from 1080p versus 720p on a smaller HDTV. And you may not even have any 1080p sources to exploit: Over-the-air broadcasts and most cable feeds top out at 1080i.

    If you’re getting a big set or if you’re connecting 1080p sources such as a Blu-ray player, a Microsoft Xbox 360, or a Sony PlayStation 3, a 1080p set is your best bet. But in many other situations, a 720p set will perform just as well for all practical purposes.

    Claim: You bought an HDTV, so everything you view will be in HD
    Status: False

    Today, not everything on television is broadcast in high definition. DVDs and shows that were recorded for broadcast under the prior analog standard will continue to look about the same as before. (Some HDTV sets even make old shows look worse, by showing off more imperfections of the original recording.)

    For satellite or cable TV service, you may need to ask your provider to activate HD content. The transition might require setup on both the provider’s end and your end; some cable boxes need to be reconfigured to output HD signals even after you connect them with the proper cables.

    A 500-station cable lineup may carry both the high-def and standard-def versions of many channels, so make sure that you’ve selected the HD version of the one you’re watching.

    Nearly all prime-time broadcast channels and many daytime shows present their content in high definition. If you don’t see a night-and-day difference between a prime-time broadcast in HD and what you remember from analog TV, something isn’t configured properly. (Check to confirm that the cable box and service provider are sending an HD signal and that you are using HD-capable cables.)

    An Xbox 360, a PS3, a cable box, TiVo, and nearly any other HD-capable device can output in either high definition or standard definition. After you connect an HD-capable cable, you’ll probably need to update a settings screen to tell the device what resolution of signal to output. Here’s how to get started with a few common devices.

    On the Xbox 360, if you’re using the component connection, be sure to flip the switch on the cable to HDTV. Go to My Xbox, System Settings, Console Settings, Display, and choose HDTV Settings. Select the option that matches your TV’s highest resolution.

    On the PlayStation 3, choose Settings, Display Settings, Video Output Settings. Select the cable type connected to your TV, and choose the resolutions that your TV can display.

    On the TiVo HD, select TiVo, Messages and Settings, Settings, Video, Video Output Format. Since broadcasters may present different TV shows at different standards, you can instruct your TiVo to keep their native settings or to scale them for your TV. Review the options here; I like to keep the Native setting.

    Claim: DRM can prevent content from playing on your HDTV
    Status: True

    Digital rights management (DRM) tools prevent you from copying copyrighted content. In most cases, HDCP — High-bandwidth Digital Content Protection — is the benevolent cop. HDCP is a handshaking protocol that provides a foundation for DRM. (The actual DRM can vary or be hidden, so look for HDCP labeling.) To avoid any problems, though, you need to use the correct gear.

    HDCP works with Blu-ray discs, digital downloads and other content sources. The technology checks for an unbroken digital connection from your content source to your TV. If the digital connection breaks off — perhaps because you connected to an unauthorized splitter or are using an analog feed — HDCP will detect that fact. In such situations, using DRM enforcement, HDCP can throttle your show quality or stop you from watching at all.

    To ensure — or to be as sure as possible — that DRM won’t prevent you from watching shows, connect an HDMI or DVI cable between your source and your TV or monitor. (If you use HDMI, then by default you have an HDCP-protected connection, and you’re good to go. But if you try to use a monitor or an older HDTV with DVI as a display device for protected content, verify in their manuals that both devices support HDCP.) If you need to connect to a splitter, receiver or other device in the middle, make sure that it supports HDCP, too.

    Claim: Brand-name cables are worth the extra money
    Status: False

    Don’t buy cables strictly on the basis of their brand name. A cable’s connector type, length and gauge are the most important factors in signal quality. As a first criterion, choose a digital cable if possible — either HDMI or DVI (just about any new HDTV will include a digital connection). Such cables can carry a 1080p signal if your content supports it, they’ll play nicely with DRM, and they won’t pick up interference the way an analog cable can.

    If you don’t have a digital connection, you can still obtain signals at up to 1080p via component cables. The resulting picture quality should still be first-rate. However, if you drop down to a lesser cable type — S-video or a single, composite RCA cable — say goodbye to your HD signal. At a minimum, your HD-compatible devices should have component, HDMI or DVI ports. In addition, they probably have S-video and composite ports for compatibility with older televisions. Avoid those ports.

    In any situation, get the shortest cables that can make the connection you need. Extra loops of cabling may pick up interference and distort analog signals, and image quality may degrade as cable length increases, especially if the cabling runs across entire rooms.

    Thicker cables can improve quality, but the difference is greatest in speaker wire. Consider buying thicker-gauge cabling if you plan to run it across a distance of 50 feet or more.

    If you take these steps, instead of reaching for a brand name, you’ll get great video and audio connections for a reasonable price. You can save even more on cables at a site such as Monoprice, where you can expect to pay a few dollars for nearly any cable type, rather than $20 to $50 for a single, brand-name HDMI cable.

    Claim: You’re in imminent danger of burn-in from letterboxing and on-screen graphics
    Status: False

    Burn-in is no longer a serious issue for HDTVs. Years ago, static on-screen graphics from network TV logos, stock tickers, videogames, letterbox bars, and other patterns could wear unevenly on a TV. If you left your set on and tuned to a station that showed such stationary elements for hours at a time, you might have been able to see them lingering when you tried to watch other content. First-generation plasma screens were the ones most susceptible to this effect.

    LCDs and other TV types haven’t exhibited this issue, and recent plasmas have incorporated effective countermeasures against the problem. If you’re buying a new set, don’t worry about burn-in.

    Plasma TV watchers may encounter temporary image retention — which can look the same as permanent burn-in — but the images eventually go away. Static images imprint themselves in a way reminiscent of permanent burn-in. But in this case, the pattern fades away with normal use. To speed up the process, play a station with a static pattern, use a PC utility such as JScreenFix, or activate the TV’s built-in mode to clear the problem.

    Claim: HDTVs can cause audio-sync problems with games
    Status: True

    Music videogames such as “Rock Band” and “Guitar Hero” require perfect timing between audio cues and on-screen graphics. If the two are not aligned, the most likely cause is that the TV is performing extra image processing, but audio is being routed directly to a receiver. As a result, the picture gets slowed down, and the audio plays too soon.

    The tiny delay that some TVs add may be perceptible only in these games, but you can turn off extra video processing in the TV’s menu system. Look for a “game mode” setting. Most recent music games can recalibrate to take the delay into account. Look for those settings in the game’s options.

    Alternatively, you can solve the problem through the audio; receivers often give users the option of adding their own compensatory delay. If your HDTV set feels a little slow when you use it for gaming, read about how to reduce your input lag.

    Claim: A TV with a faster refresh rate can look better than a slower TV
    Status: True

    In the past few years, vendors have marketed TVs with refresh rates of 120Hz, 240Hz, and beyond. These sets can interpolate frames between the ones you’d normally see, thereby smoothing out motion through enhanced picture processing.

    HDTV testing has demonstrated a correlation between high refresh rates and smoother image quality in TVs. However, we occasionally see high-refresh-rate TVs whose images look more jittery than those on 60Hz sets. These discrepancies arise because smooth motion performance depends on the combined operation of the panel’s refresh rate and the software algorithms inside the set.

    As 3D-capable TVs come to market, refresh rate will play an increasingly important role in picture quality. One technique used to produce 3D effects requires input and playback of a 120Hz signal. (Practically all current TVs accept only a 60Hz signal, regardless of their advertised refresh rate.) Look for 3D branding and a 120Hz input in those cases.

    For those who are using total video converter, this post will be useful for you.Ever encounter following problems:

    Total Video Converter Tip1: tried of slow conversion speed? You can select stream copy to speed up the conversion speed, while maintaining the original audio or video effect.

    Total Video Converter Tip2: When running conversion, if you want to run other program simulataneously, you can release one or several core of multi-core CPU for smooth running.

    Total Video Converter Tip3: When running conversion, you can take full advantage of multi-core CPU’s ability to speed up the transcoding speed

    Total Video Converter Tip4: You can convert directly to music CD to Lossless Audio like APE, FLAC or other popular lossless formats. It will reduce the file storage space and the physical disc storage space without reducing the sound quality. You can also enjouy genuine CD in smart phone like iPhone, Blackberry or Windows Mobile phones.

    Total Video Converter Tip5: If some conversion failed like RM, you can click “Prior decoding with DirectShow” after loading the file, then process the conversion.

    Total Video Converter Tip6: Windows Mobiles phone can only support audio file with the sampling rate <= 44100Hz. If more than 44100Hz, some error may occur during playing.

    Total Video Converter Tip7: If you try to convert animation or cartoon,  you can reduce the frame rate to 16fps or 12fps, which will dramatically reduce the file size. Or you can select higher resolution to obtain a better quality.

    Total Video Converter Tip8: You can add subtitles for the conerted videosby just clicking “effect” – “” subtitles “.

    Total Video Converter Tip9: Sometimes even with high bit-rate, the output video quality is worse than the source. You can try to modify the qmax and qmin parater in professional setting. Both parameters usually range among 1-32. The smaller the value, the better video quality (closer to the source of quality), the larger output file. You can choose qmin=2 and qmax between 6-10 for high quality output.

    Total Video Converter Tip10: Most of above tips also works for DVD Ripper

    The Apps

    The native iPad apps have shrunk in number versus the iPhone, and—with the exception of Safari, Mail and the App Store—the remaining apps carry much less weight. Which is to say, you won’t use them as much as you do on an iPhone. The iPad is really all about the applications and content that developers will create.

    App Store and iTunes
    Quite honestly, the App Store on the iPad is now the best way to get apps. Navigating and finding apps feels far more serendipitous and engaging than pointing and clicking on a desktop, and with the screen real estate, you can actually see the store and app previews, unlike the iPhone. It manages to fracture one of biggest advantages, though, by jerking you out of the App Store every time you buy an app. This should feel seamless, and allow for more of a shopping spree. If the transactions happened almost invisibly, it wouldn’t feel like you’re spending money as apps pop onto your iPad, and you wouldn’t feel like you’ve got whiplash, either.

    Also, the most fundamental problem with the App Store remains: The interface breaks down when you’re trying to sort through a sea of 150,000 apps to discover a few you’d really want. And the iPad’s sole surviving instance of Cover Flow, a floating widget of app previews at the top of the home screen? Kinda gross lookin’.

    The iTunes store looks and feels like the App Store in terms of basic navigation and layout, but it’s obviously built around previewing and purchasing music, movies and TV shows, so the interface is kinda like a touchified version of the main iTunes Store interface on the desktop. Tapping album covers or film posters flips them around to show you the basic info with previews. One of the big changes is being able to download movies—even 5GB HD flicks—over Wi-Fi. (Though I wouldn’t really recommended it, since my bigger download errored out a whole bunch.)

    Safari
    The velocity of scrolling, zooming and panning around web pages in Safari is one of the first “whoa” moments you’ll have with the iPad. It’s superfast, which is why it feels so awesome. The size is the other component—being able to see that much of a website radically alters the experience, turning it into something that’s incredibly satisfying. Really, you’ve never felt anything like it.

    There are a few problems, though. (And I’m not even talking about Flash. In case you were wondering, no, there’s still no Flash. It hasn’t affected me once since so many sites have remade themselves for the iPad, and the one time I did get upset, I quickly remembered that a Hulu app is coming. YMMV without Flash though.)

    Safari’s one place where the iPad’s memory shortage makes itself apparent, since you’re limited to nine windows, and quite often, it dumps the contents of a window, so when you go back you’ll have to reload the whole page. That’s pretty annoying. This is also, I suspect, why it doesn’t have true tabs: People aren’t encouraged to open a bunch, because it can’t handle it. Still, tabs would be incredibly welcome for the sheer fact that the iPhone-originated process of switching between windows (click the button, you’re taken to a thumbnail view of your windows, then click the window) feels more tedious than ever. With this nice big display, it shouldn’t take two screens and multiple seconds to switch to a new window when everything else practically flies.

    Something else we’d like? Text enlargement, like in desktop Safari. Our own Jesus, like many old dudes, prefers larger text. There’s no reason it can’t be done now. And when we’re scanning whole, giant web pages, there’s really still no “find in page” search feature?

    Photos
    The traditional photo album grid has never felt slicker. Zooming in really fast, incredibly smoothly, on huge photos is definitely one of those “oooo” moments, as is “pinch to peek.” The problem? Getting your photos on there and syncing is still pretty messy, pulling them in albums via iPhoto or in specific shots via iTunes. Legitimate connections to online photo services would be nice too, so you could populate it with your Flickr or Picasa or Facebook photos. Hopefully these services will soon roll out apps to handle this from their end.

    Mail
    Given that it looks so much like its iPhone forebear, perhaps more than any other iPad app, you’d be forgiven for not realizing it’s one of the most important apps on the iPad. In truth, it makes use of every new bit of user interface, and it’s the starting ground for so many other apps, from RSS readers to Instapaper to Twitter clients.

    In landscape, it uses the split view, with your inboxes or messages on the left, and the contents you’ve selected on the right. The panes look and feel like their respective iPhone screens, just fused all together. If you hit “new message” or “reply,” an overlay pops up with the keyboard, which takes up half the screen, and a message box that doesn’t quite cover the entire top half of the screen. (You’ll see this messaging overlay pop up again and again in apps like Twitterific.) Adding contacts takes place via a scrollable popover—like the old contacts list, but it doesn’t take up your entire screen.

    Portrait mode is more focused: When you select a message, it’s all you see. To switch to a new email or look elsewhere in your accounts, you have to bring up a popover, which runs down the entire length of the iPad shows you the rest of your inbox. The mode overall is good if you have a hard time concentrating, but navigating via the popover can feel a little disjointed.

    Overall, Mail works great, but the same functional limitations as the iPhone version still apply, like no unified inbox, no push Gmail, and the inability to attach a file to a message from inside the app. The list goes on, and these shortcomings feel more pronounced because of the power and size of the iPad.

    Contacts, Notes and Calendar
    Contacts is one of the literal “I’m a book!” apps that takes it a little far for no apparent reason. But cheesy art effects aside, in structure it’s like iPhone contacts but with a two-pane view, like the Mac Contacts app. Notes is essentially the same as the iPhone with more “realism” added via the subtle outline of stitched leather surrounding the yellow legal pad. It’s still gross.

    Calendar, on the other hand, is a graceful application that makes the iPhone Calendar feel too constrained, and the desktop iCal feel too convoluted. Sort by day, week, month or list (showing the next 10-15 events). In day or list view, the list of events is in the left pane, and a closeup of individual events or days is in the right pane. Week and month views zoom out to a traditional calendar view, where popovers reveal event details. A scrubber on the bottom lets you quickly zip to any day or week, depending on the view. It’s really nice, at least for basic calendar usage.

    Maps
    It’s iPhone Maps, but bigger and so, so much faster, and that’s a world of difference when you’re talking about zooming around the world.

    YouTube
    It’s hard to believe this is YouTube, almost—it looks too polished. The streamlined interface is miles ahead of what you get when you type youtube.com on your desktop. I can actually just sit and watch YouTube for the first time ever, also thanks to the surprisingly great video quality.

    iPod and Video
    iPod seems a little out of place, I have to say. It doesn’t quite look like anything else, though that’s not necessarily a bad thing. It’s the jukebox essence of desktop iTunes, stripped to the silver bone because it only does one thing: Play music. Considering what iTunes is like on the desktop, that’s kind of refreshing.

    Videos is similarly stripped down. It shows you videos. Touch, and it flips to info about the video. Touch again, and it plays. (Our test notes on iPad video here.) Generally speaking, anything shot in artsy super widescreen looks a little weird—like any Wes Anderson movie—since there’s a ton of black between the bars and the bezel. The rub is that the movies where that effect is the worst also suffer the most from zooming to fill the screen, chopping off massive amounts of the picture. (A necessary evil, unfortunately.)

    Apps that essentially mono-task are fine, and they definitely expose how goddamn unwieldy the desktop iTunes as grown (as well as the fact that Apple is aware of this), but there are definitely missing features we’d like to see. If the iPad is designed to be used in your house, why can’t you music and videos from your desktop to your iPad using iTunes, right inside these apps? Seriously. And why isn’t iTunes Remote iPhone app updated for iPad, to be used to control your desktop’s iTunes? Little things like that would add up to make the iPad feel that much more connected.

    Magic Spells, a Computer and a Cloud

    The moments where the iPad’s spell dissipates are when it runs into this uncanny valley between unique modal tablet and standard personal computer: It feels so much like a computer from the future sometimes that you just expect it to do stuff you can do with your laptop. When it can’t, you get kind of depressed. Like when you want to flip a couple of IMs out without ditching your entire Scrabble game, or you really just want to send an attachment in Mail, or do something really basic like save a PDF so you can read it later. (You can’t do this without a separate 99-cent program, GoodReader; without that, you have to re-download your PDF every time.)

    And how about the entire setup process, which slavishly ties it to another computer with iTunes. It can’t replace your parents’ complicated desktop, because you need that complicated desktop to setup the iPad, and then to manage your music and videos (not to mention software updates down the line), so it’s frozen as a secondary device. Then are the moments you wish it was more connected, like a phone. Take the Nexus One. Two minutes out of the box, a minute after punching in my email address, all of my contacts and emails are there. I didn’t plug it into anything.

    In other words, it’s the moments where the iPad feels like it could be more, and you know it in your hands, in your fingers, as you’re holding it. That it has this potential to do this or that, but it doesn’t yet, and you really really want it to, because you’re so incredibly enthralled with everything it already does.

    Potential. Promise. Hope. That, if anything, is the real magic of it. In the meantime, it’s off to a pretty good start.

    On Multitasking

    The iPhone evangelized the rather retro notion of running just one app at a time. And this has been mostly fine (though by no means excellent), given the screen size, and with workarounds like push notifications. The limits of these workarounds are more painfully exposed by the iPad’s giant screen: Switching out of a game or movie or email to dedicate the entire display to instant messaging feels absurd and wasteful, even considering that, in landscape mode, half the screen is dedicated to the keyboard.

    What’s sad is that the kinds of things people commonly want multitasking for—mostly people who don’t even care what true “multitasking” means—seem simple enough, even for this operating system: Messaging, geolocation and playing music from apps like Pandora in the background. Even though Pandora makes beautiful use of all the room it’s granted, not being able run it in the background while surfing the web, typing out an email—or hey, sending an IM—just feels ridiculous in so many ways. Every time you have to close it to do something else, a little bubble of fury rises in your throat, erupting as a flustered sigh. I really can’t respond to my friend’s message without closing everything I’m doing on this huge thing? The choices you’re being forced to make feel false and arbitrary, like bacon or eggs.

    The modal nature of push notifications stabs your brain harder too, like when your zombie slaying groove in Call of Duty is wrecked without warning by a little blue square that takes over your entire screen, informing you that a new IM is waiting. It just doesn’t work. At the very least, notifications need to be implemented very differently, because the iPad is meant to be immersive—and it really is—and to have that shredded by a workaround for capabilities it currently lacks, that’s kind of heartbreaking. Something like Growl, that’s unobtrusive, could work. (This will hopefully change with iPhone 4.0.)

    The hardware constraints that made running one app at a time make sense are nearly obliterated in the iPad—the battery and screen are an order of magnitude larger, the processor markedly zippier. I suspect the remaining hardware cramp may now be the paltry amount of RAM in the iPad, a mere 256MB—the same amount that’s in the iPhone 3GS—but it doesn’t really matter why. As Apple’s fond of intoning, people just want it to do what they want it to do.

    Put simply, the iPhone might not need multitasking. The iPad does.

    Mimesis, or a Love Affair with Paper

    For a blank slate that can magically transform into anything, Apple’s preoccupation with mimesis might seem a little curious. The Contacts app looks like a Moleskine address book while Calendar imitates a real-world datebook—though it functions so beautifully and smoothly it’s very possibly my favorite native app. iBooks uses a bookshelf metaphor that practically smells of rich mahogany, and books whose pages turn with a realistic animation that you can’t turn off. Ticking off messages in Mail stacks them like a pile of paper. In other words, Apple wants their apps to feel something like real-world experiences.

    As Jesus noted, “Apple designed this device to be treated like a book,” and this carries through to any app that’s an abstraction of paper. Maybe it’s meant for your parents to feel more comfortable using the iPad to read books and organize their contacts and calendars, but the implementation of the realism feels so cheesy in some places that it’s simply not comforting, not even to that target audience, I suspect.

    Typing

    Yes, it’s pretty much a jumbo iPhone keyboard. (An idea that seemed so silly, we made fun of it.) We have been typing on the iPad in depth here, but simply put, an external keyboard is ideal. Still, as we noted earlier, the compromise here “is going to be inherent to all touchscreen keyboards on tablets.” There’s no novel solution, not for Apple or anyone else.

    I got several email from my readers, asking why choose iPad.

    Michael from Oregon dropped me a line as below “There have been lots of tablets or MIDs before the iPad. Why no one pick them up?”

    Yesterday I found one post in gizmodo written by Matt, which answered Michael’s inquiry ” Those tablets weren’t as beautiful or well crafted, but that wasn’t why we chose not to pick them up. It was the software.”.

    Yes, iPad is iPad because of the software.

    Those who call the iPad “bigger iPhone” ignore one simple fact: changing the screen size really does change everything. Yes, everything changes. It’s more than the difference between SD and HD, between 5 1/4-inch action figures and 10-inch scale, between vegan facon and real pork belly. In a word, “The iPad functional objective was to make the product as invisible as possible, a simple, elegant stage for the real important actors: The applications.”

    iPad’s Interface

    The iPad looks familar to iPhone/iPod users, with a grid of glossy icons—touch one, and the app balloons out of nowhere to fill the screen. It’s a simple, slick and natural interface designed to be manipulated entirely with your fingers, and the basic elements of all translate, just on a slightly grander scale.

    Speed. Speed matters. When the hardware disappears, and there’s just software in front of you, speed is what makes the verisimilitude of directly manipulating whatever’s the on the screen bleed into the sublime. It’s the responsiveness that makes you feel like you’re actually zipping around a map, not swiping at a screen that’s merely interpreting electrical signals generated by your fingers into commands. The second “wow” moment—after you turn the iPad on and the screen bursts to life—is when you flick through a entire web page with a single swipe, instantly and smoothly.

    One of the ways it’s fundamentally different from the iPhone is that the interface and software are now truly designed to be used equally in both portrait mode and landscape. It sounds like a small thing, but it’s not—it gives power to the idea that you can use it however you want, that it’s really a blank slate that morphs to become whatever you want it to be. It’s remarkably proficient at figuring out exactly how you’re holding it, and the software gracefully, speedily adjusts itself accordingly, rolling into position. All of the core applications—Safari, Mail, iPod, Notes—shift into new layouts, optimized for whichever way you’re holding it. It feels so natural so quickly that you simply expect it to be the case, so when third-party applications don’t remold themselves to how you’re holding the iPad, it’s jarring.

    Two new user interface conventions in particular transform apps to make real use of the extra space with either more information density or greater focus: Split view and popovers. (Twitterific isn’t a native app, but it shows off both here.) Split view appears in landscape orientation, and presents two windows panes—typically, on the left is navigation (your various inboxes in Mail, music sources in iPod, all of your notes in Notes) and on the right is whatever you’ve selected (a message, an album, a note). On the iPhone, this would be two distinct screens—you click on something in one pane, and suddenly you get the other pane—drilling down instead of working in parallel. Many apps, particularly ones that are using mail as a UI model, like Instapaper, use this.

    Popovers, a kind of contextual pop-up dialog box layered on top of whatever you’re looking at, are in almost every app. Completely contextual, they can act as navigation panes (like when Mail’s in portrait mode, a popover shows all of your messages or inboxes); or typing a URL in Safari, a popover will appear, showing suggested URLS based on your history; or a scrolling list; or as a navigator to pick out a photo to load into iWork. It’s a second layer, one that never existed on the iPhone because there isn’t enough space.
