I have one MP4 movie that plays just fine in QuickTime (I've run it from beginning to end without problem).

However, when I imported it into iTunes, it can load but cannot play. Clicking on the play/pause button does not work. Nevertheless, I can advance the progress bar to any point in the movie, but the screen just shows a still image of that point.

This is really strange since as far as I know, iTunes plays movies with QT.

So, what is the possible cause of this problem and how to fix it? Thanks in advance.


My environmental specs: OS X 10.8.4, iTunes 11.0.4 (4), QuickTime Player 10.2 (603.17).

I suspect that the codec is the issue. You should probably try to re-encode the movie. There are a multitude of encoding apps out there such as Handbrake.

Had a similar problem recently and solved it by using Subler, which is way faster than other alternatives (not as many features though). Just make sure you have the correct settings in Subler and Perian.

I have Audio Output on Multi-Channel in both and AC-3 Audio to AAC is checked in Subler

Thanks for the suggestion. As for me, I re-encoded the video with Handbreak, which is not very fast (30min lossless encoding for a 90min movie in this case) but nevertheless user-friendly and versatile (I mainly use Handbreak for ripping movies from DVDs). I have removed the problematic MP4 so I can't test your solution. But seems that you mentioned Perian, which ceased development earlier this year. –  KevinSayHi Aug 19 '13 at 14:27
    
Yeah I know they stopped developing it but the latest version works for subler, now atleast –  Oskar Persson Aug 19 '13 at 16:17
