The Moving Picture: Lessons from iTunes

I recently gave a presentation on producing H.264 video at Streaming Media West. During my preparation, I noticed that while H.264 is the hot topic in periodicals and forums, it’s still not widely used for streaming, with Windows Media and VP6-based Flash still predominating. In one market segment, though, H.264 was nearly ubiquitous, so I decided to spend some time learning about how H.264 was used—and misused—there. The market I’m referring to is video podcasts distributed via iTunes. iTunes is all about iPod/iPhone devices, which play only H.264 and MPEG-4 video. Finding H.264 video in iTunes is like finding Red Sox fans in Boston, Bulldog fans in Georgia, or Yankee fans in New York.

Having found the Mecca of H.264 usage, I decided to download 50 podcasts, try to load them on my iPod Nano, and see what happened. Six refused to load at all, and three had what I’ll call "potentially sub-optimal" displays. After analyzing all the podcasts in Inlet HD’s excellent streaming media analysis tool, Semaphore, I noticed that many others used suboptimal encoding parameters. While producing podcasts is probably a tiny part of what we do, it’s still a useful skill, so I thought I would detail my findings. First, here’s some background. MPEG-4 is the overarching standard that includes two video codecs, the MPEG-4 codec itself and a more advanced video codec, H.264, also known as AVC. When used in an MPEG-4 "wrapper," H.264 files typically have a .mp4 or .m4v extension, the first being the official designation and the latter being the extension Apple created for its devices.

You can also "wrap" an MPEG-4 file in a QuickTime file with a .mov extension or encode it for Flash with a .flv or .f4v extension. Soon, you’ll be able to encode H.264 to Windows Media presumably with a .wmv extension. H.264 has multiple "profiles" that specify levels of playback compatibility. For example, the Baseline profile is typically for devices like iPods or cell phones that have limited playback horsepower. Accordingly, the Baseline profile doesn’t use many of H.264’s more advanced encoding techniques that can produce higher-quality streams, but it may also create a stream that’s hard to decode. Then there’s the Main and High profiles, typically for computerbased playback, which produce a tighter, higher-quality stream that’s harder to decode.

Obviously, when producing for devices rather than generalpurpose playback, job No. 1 is to use the appropriate profile. Interestingly, of the six videos that wouldn’t play on my iPod Nano, five used the Main Profile, which is verboten. The sixth used the Sorenson Video 3 codec, of all things, which also won’t play.

So when producing for podcasts, always use the Baseline profile of the H.264 codec. Before encoding, however, go to Apple.com, print the video playback specs for the latest iPod, and make sure that you’re within the resolution and data rate requirements. Unfortunately, this is more complicated than it sounds because the initial iPod could only play H.264, Baseline-profile videos at 320x240 resolution, while current iPods and iPhones can play Baseline H.264 video up to 640x480 resolution.

Next is target resolution. In the sample of 44 videos that loaded on my iPod Nano, 25 went with 320x240, which is obviously the safer route, while the other 19 (and five of six that failed to play) went 640x360 or larger. Why go larger than 640x480 when the screen resolution of most iPods is 320x240? First, many iPods have composite output ports that let you play the video on a TV set or other analog device. Though display on the device itself is limited to 320x240, 640x480 video will look better than 320x240 when displayed on a TV set. More importantly, iPhones and the iPod Touch have 480x320 resolutions, and six of the 19 producers using greater than 320x240 resolution produced at 16:9, which looked better on the iPhone/iPod Touch than 4:3 video.

This leads me to the three podcasts with "potentially sub-optimal displays." Briefly, if you display 16:9 video on a 4:3 iPod, by default, the device displays the middle section of the video and cuts off the right and left edges. Several producers of 16:9 video—including Photoshop User TV—included screencam videos with content on the edges that wasn’t visible when viewed on a 4:3 display. As a result, while the announcer says "click this menu item," the menu item may have been offscreen on 4:3 displays.

Note that your viewers can change this default in the Movie menu and display the entire 16:9 frame with letterboxes on the top and bottom of the video. Since most iPods have 4:3 displays, if you’re going to produce 16:9 video, either make sure that all critical content is visible in the 4:3 center cut, or advise your viewers to change the default to display the entire frame within letterboxes.

The other mistakes I found were technical, like exceeding the recommended data rate and using too-frequent keyframes, which can degrade quality and add a pulsing effect. So it’s worth noting that the iPod preset in Apple Compressor uses a bitrate of 1.12Mbps for 640x480 video and inserts keyframes every 150–300 frames, depending upon content, or one every 5–10 seconds.

Microsoft Releases Silverlight 2

Microsoft Corp. today announced the availability of Silverlight 2, one of the industry’s most comprehensive and powerful solutions for the creation and delivery of applications and media experiences through a Web browser.

Silverlight 2 delivers a wide range of new features and tools that enable designers and developers to better collaborate while creating more accessible, more discoverable and more secure user experiences.

Microsoft also announced further support of open source communities by funding advanced Silverlight development capabilities with the Eclipse Foundation’s integrated development environment (IDE) and by providing new controls to developers with the Silverlight Control Pack (SCP) under the Microsoft Permissive License.

"We launched Silverlight just over a year ago, and already one in four consumers worldwide has access to a computer with Silverlight already installed," said Scott Guthrie, corporate vice president of the .NET Developer Division at Microsoft. "Silverlight represents a radical improvement in the way developers and designers build applications on the Web. This release will further accelerate our efforts to make Silverlight, Visual Studio and Microsoft Expression Studio the preeminent solutions for the creation and delivery of media and rich Internet application experiences."

Silverlight adoption continues to grow rapidly, with penetration in some countries approaching 50 percent and a growing ecosystem that includes more than 150 partners and tens of thousands of applications. During the 17 days of the 2008 Olympics Games in Beijing, NBCOlympics.com, powered by Silverlight, had more than 50 million unique visitors, resulting in 1.3 billion page views, 70 million video streams and 600 million minutes of video watched, increasing the average time on the site (from 3 minutes to 27 minutes) and Silverlight market penetration in the U.S. by more than 30 percent. Broadcasters in France (France Televisions SA), the Netherlands (NOS), Russia (Sportbox.ru) and Italy (RAI) also chose Silverlight to deliver Olympics coverage online. In addition, leading companies such as CBS College Sports, Blockbuster Inc., Hard Rock Cafe International Inc., Yahoo! Japan, AOL LLC, Toyota Motor Corp., HSN Inc. and Tencent Inc. are building their next-generation experiences using Silverlight.

Digital Heaven Releases Loader - The Smart Way to Import Media into Final Cut Pro

Digital Heaven, one of the leading third party developers for Apple Pro Apps, today announced the release of Loader, an innovative application that streamlines the process of importing media into Final Cut Pro.

Importing music, sound effects, graphics or movies into Final Cut Pro is a task that most editors do many times a day. In order to keep media files in one place for a particular project, it has traditionally been necessary to first copy the files to a media folder and then import the copied files into Final Cut Pro. Loader handles both of these processes automatically and adds some extra benefits.

Loader works alongside Final Cut Pro (launching and quitting automatically) and appears as a small tab on the left side of the screen. When tracks from iTunes or files/folders from the Finder are dragged onto the tab, it slides out to reveal a list of projects currently open in Final Cut Pro. After dropping the items onto the desired project, Loader copies them in the background to the assigned media folder linked to that project. In addition, those audio file formats that don't play nicely in Final Cut Pro (.caf, .m4a and mp3) are automatically converted to a 16 bit 48kHz AIF file before import. When the copy is complete then the copied files are sent to a new bin in Final Cut Pro.

Loader also offers the ability to sort copied media into subfolders according to the file extension. By default, subfolders are automatically created for audio, graphics and movie file types and settings can be changed at any time to suit specific requirements.

"I love Loader - no more messing about outside of FCP converting music to the correct format, just drop it on the Loader window and get right back to work. Simple and effective." - Jude Cotter, Freelance Editor, Perth Australia

Pricing and availability
Loader is available for immediate purchase from the Digital Heaven online store for US$49.00. A fully working 14-day trial version can be downloaded from the Digital Heaven website.
