Why can't my iphone 4 play this 720p video?

Post by rk518 »

Here are the video specs:
Resolution: 1280 x 656
Bitrate: 17.25 constant quality from blu ray = about 8,000 kbps
Frames: Same as source, variable
Audio: AAC CoreAudio 192kbps
Reference frames: 12
B frames: 10
Large file size: Checked

When every i drag the file over to my iphone in itunes it says that the file was not copied because it can not be played. If you know a setting i need to change to make it playable based on the above please let me know. If you need anymore info on the video file feel free to ask.

Also according to the specs, iPhone 4 "only" supports video up to level 3.1 and yours looks like 4.0.

If you want to know more about levels, read http://en.wikipedia.org/wiki/H264#Levels; If you don't have an interest in learning what levels are, use one of HandBrake's "A4" presets (AppleTV 2, iPhone 4, iPad) and be done with it.
