iPhone “cannot play” .mp4 H.264 video file http://stackoverflow.com/questions/3285529/iphone-cannot-play-mp4-h-264-video-file devices only support .mp4's that are encoded with the baseline H.264 profile or they can't be played. Also there's a bitrate limit of 1.5Mb for the iPhone but it's suggested to keep the bitrate below 900kb. If quality is less of a concern than size.. profile or they can't be played. Also there's a bitrate limit of 1.5Mb for the iPhone but it's suggested to keep the bitrate below 900kb. If quality is less of a concern than size then you can use m4v's of larger dimensions but I believe the bitrate..
