As a Flash Professional user, you probably have Adobe Media Encoder installed on your computer. This is a great tool to encode videos not only for Flash video player but also for other H.264-enabled devices like iPhone and Android. However, when I tried to encode a video using a random H.264 preset, my phone (a Milestone 2) could not play the video. This means that not every export settings is compatible with the phone’s internal video encoder.
So which preset should we choose for the export settings?
