No audio in QuickTime on Intel Mac for .avi movie

posted in Audio Codecs

Hi,

I’m trying to play an .avi movie. The movie info in QT says the video codec is DivX 5.0 and audio codec is 'ms'. VLC is able to play the movie fine, and it says the audio codec is a52. I have already installed the requisite divx, xvid and perian codecs. I have also set perian properties to stereo. I’m not sure wats wrong still.

I also have a separate problem with a different video file where QT shows no audio or video, just a green screen. Again, VLC plays fine. This time the video codec is Generic MPEG-4 and audio codec is mp3.

Please help!

A52 usually means AC3 audio. The perian page says it includes an AC3 decoder. Do you have the latest version?

For the other file, what do you mean generic mpeg-4? Doesn’t it give a fourcc in videolan? And what’s the container? reply

Hey this solved a few of my problems, but I still have trouble with some sound on some .avi clips. I have one right now that has sound in reverse but not when playing. Any other ideas or codec sources? reply

As a great open-source QuickTime component, Perian is the saver to allow QuickTime to play all kinds of AVI videos for Mac users. Unfortunately, the latest version 1.2.3 of Perian is not compatible with Mac OS X Mavericks(10.9), Mountain Lion(10.8) and Lion(10.7).

If you insist to convert AVI to QuickTime MP4/MOV, the above converter is also your best choice. There is a guide to help you at: http://faasoft.com/articles/quicktime-avi.html
