For these recommendations, we're going to use Speed 2, which improves compression a bit over the baseline but is still reasonably fast.

Speed: set this based on desired turnaround time.

If the audio specifications change from one version to another, the user may hear pops and clicks during playback when switching streams.

Be sure to keep the audio identical across each video.

The efficiency gains are small, especially at high resolutions, but at lower resolutions they start to make a difference.

This makes for more efficient compression.

As much as possible, these settings allow for resolution dimensions divisible by 16.

The resolution scaler on the iPad is pretty good, so videos that are rescaled will generally look good.

iPad and iPhone 4 users will be able to make use of all six streams.

Legacy iPhone/iPod Touch users will have three streams available to them, including a reasonably high quality 480x320 video (the screen resolution of these devices).

so add or subtract resolutions and profiles as desired.

You could certainly do more - Apple recommends 8

These 6 resolutions and bitrates provide reasonably good coverage of varying bandwidth.

Of course, for truly optimal device targeting, encode to both Main and High. iPad 2/iPhone 4S support High profile, which is marginally better than Main, but given the tens of millions of iPad 1 devices in the world, it is probably better to stick to Main profile. iPad 1 and iPhone 4 both support Main profile.

Future iPads, by the way, are rumored to have 4x the resolution of the current iPad, so consider adding 720p for future-proofing.

Unless, of course, you want to reuse a video somewhere else - 720p is a great resolution for fullscreen web playback, and 1080p is entirely appropriate for connected TVs. But since the native display is only 1024 pixels wide, going all the way to 720p or 1080p isn't critical.

720p is the largest video playable on iPad 1 and iPhone 4, and iPad 2/iPhone 4S play anything up to 1080p.

For example, extremely complex content may warrant higher bitrates. Different resolutions and bitrates are perfectly valid, and may actually be preferable in some circumstances. Zencoder fully supports HLS, and does so better than anyone else in the cloud.

HLS is also being adopted by Android (version 3+), Roku, and a range of other destinations. Apple requires it of any video app in the App Store that plays content longer than 10 minutes, and it is the only true streaming format supported by iOS.

For the best user experience, HTTP Live Streaming is a must. iPhone 3GS and earlier only support H.264 Baseline profile, level 3.0 (and some support a more constrained version than that), whereas newer devices support Main and High profile. On the video side, use multiple profiles to target each device. HE-AAC sounds reasonably good at these bitrates, even for complex audio. On the audio side, consider using HE-AAC at <64kbps, for App Store compliance. Like most video today, use H.264 video and AAC audio when targeting iOS. (For deeper information on HLS and iOS video, be sure to download our guide to iOS video, which goes into more detail about HTTP Live Streaming and iOS video delivery.) General settings

We're going to start publishing our recommendations to our blog and to our docs in an effort to help Zencoder customers (and non-customers) make good decisions about how to encode video for a wide range of targets: mobile devices, Flash, Silverlight, HTML5, connected devices, and more. At Zencoder, we get asked for encoding recommendations all the time, and we end up recommending the same (or similar) settings over and over.

This article is the first in a series of encoding recommendations. We've written about this before but our previous guide only described how to ensure mobile compatibility - not how to find the best settings. Fortunately, with just a few encoding profiles, you can stream high quality video to every iOS device, from the first iPhone to the iPad 2, and even prepare for future generations of mobile hardware. iOS devices have gone through several generations of technical capabilities, and the ideal video settings for the iPhone 4 are not ideal for the iPhone 3GS or for the iPad. Encoding for iOS is a little tricky, though. For some major publishers, iPad delivery represents 1/3 of total video views - or more. Any serious video publisher either already supports iPad and iPhone, or needs to think hard about adding support. You already know this, but iOS video is a big deal.
