The iTunes podcasting team has just released some recommendations for formatting video podcasts now that Apple TV is here.
Excuse me while I smile....
1. If you're encoding your video podcast at 320x240, please increase the resolution to either 640x480 or 640x360 (depending on the aspect ratio of your source files). Why? Because video podcasts at this resolution look great on Apple TV and still port to video iPods. Lower resolution podcasts might also work on both platforms, but they don't look nearly as good on a widescreen TV. As always, make sure to test any encoding changes you make to ensure device compatibility. QuickTime 7.1's "Export to iPod" function will ensure that a video file is encoded at a width of 640 and is iPod-compatible.
Ah yes, 640x360 is a great resolution for 16:9 content and looks OK on the iPod, your Mac and at a push, Apple TV .
Did I mention I've been releasing my free feed in this resolution since October 2005!
2. It's best not to create two different podcast feeds for different resolutions. By doing so, you dilute the popularity of your podcast and reduce exposure in our charts. It's better to have one feed high in the charts than two that are lower.
Noooooo...... Create two feeds, one at 1280x720 and label it - AppleTV HD and then do a second feed at 640x360 and label it iPod. We need to be able to identify which is the good stuff and having a HD feed will give you some Kudos. If the bandwidth is a killer, get a Libsyn account or use a third resolution (960x540) to bring the file sizes down. Call the third feed - AppleTV ED (enhanced definition). As far as diluting exposure via iTunes, Apple - give us a way to aggregate multiple shows together so that people don't suffer from having multiple feeds.
Did I mention I've been releasing my premium feeds in 1280x720 and 960x540 via iTunes since October 2005!
3. If your source files are 16:9, stick with that aspect ratio. Don't add letterboxing to make them 4:3. By doing so, you prevent the video from expanding to fill a 16:9 widescreen TV and instead end up with black space on all four sides. Also, your original source files should be at least 640 pixels wide.
Absolutely!
Sorry, I know I may be repeating myself but it's great to be proved right and be ahead of the game :-)
