Best flash streaming video frame sizes iOS, ipad/iphone/ipod
Generally speaking, for the best streaming video quality and playback the width and height dimensions should be a multiple of 16 (best), 8 (better), or 4 (good). This applies to Video On Demand as well as Live streaming.
If you are pushing a live stream using Adobe Flash Media Encoder for use with iOS devices we suggest using dimensions of 640 x 360 or 480 x 272 for 16:9 aspect ratio. For 4:3 we recommend 640 x 480 or 480 x 360. The video (deinterlaced) should be H.264 baseline level 3.0 to cover the most devices along with AAC audio and not MP3. Key Frame every 1 or 2 seconds. For lower bit rates use a frame rate of 15. Apple recommend that an audio sample rate of 22.05 kHz and audio bit rate of 40 kbps is recommended in all cases for mobile/cell phone steaming. We find results are good with bit rates up to 64 kbps, 44.1 or 48 kHz provided that this is not more than 10% of the video bit rate. N.B: A delay in playback is normal with iPad and iPhone.
The tables below are settings recommended by Apple who require the video width to be 480 or 640:
