Which video formats can Ai play?
Ai is a QuickTime capable application, which means that most files which play in QT “should” play within Ai. However, please note that Interframe codecs (such as h264, mpeg2,4 etc) and other CPU based codecs will significantly reduce playback performance. For this reason, we always recommend using the AiM codec as this will give the very best results for your show.
Please note that our support engineers will always insist on the use of the AiM codec as this is the only codec we use internally for testing.
For Further information on the AiM codec please take a look at this detailed document – AiM Codec Analysis
