    Hi folks. New to Mac Forums and Macs in general. Just bought a brand new Intel iMac last night in fact. Anyway, my problem is playing AVI videos with Quicktime. Originally, I couldn't get the sound to work at all. I installed a few codecs and tried MPEG Streamclip. Streamclip originally worked and I was able to play the videos with sound, but no sound from Quicktime. However, after a reboot, both Streamclip and Quicktime play sound, but it's all sped up and distorted. Here's what Quicktime reports my format as:

    Generic MPEG-4, 640 x 480, Millions
    MPEG-1 Layer 2, Stereo, 44.100 kHz

    I have the following components in Library/Quicktime:

    DivX Decoder
    DivX Encoder
    XviD_Codec 1.0 alpha
    Save as AVI

    If you have any suggestions, let me know. Like I said, I'm brand new to Macs and I'm sure I messed something up here.

    Its hard to say if your quicktime is fine or not.

    However, I do recommend VLC media player, which is probably the best media player all around for OSX.

    I think you might have too many things in there :)

    I installed Perian and Flip4Mac. Between those two, there is almost nothing that my Quicktime cannot play. Consider uninstalling all your plugins, and then starting over again, this time with just Perian and Flip4Mac

    So, I tried uninstalling everything but Perian and added Flip4Mac, but no luck. I then reinstalled the Divx codecs and removed Perian and it worked again in MPEG Streamclip, but still no sound in Quicktime. I read that Perian 1.1 has caused some problems so I tried 1.0. With that, I got audio for about a second with Quicktime before it disappeared and eventually Quicktime locked up on me altogether. I guess if Streamclip is working, that's better than nothing, but I would like to use Quicktime if at all possible.

    make sure you have the most up to date version of quicktime as well, because that works with perian to play almost everything.

    Yep, that's all up to date, but Perian seems to be creating more problems than helping. At the very least I can convert the files with MPEG Streamclip to a format Quicktime understands, but the file size triples (at least with MPEG-4 format). I'll have to play around with it some more to see if there's a more efficient format.

    The Answer!

    to .avi's with no sound in Quicktime!


    I've got Flip4Mac pro, all the codecs Apple features; nothing worked.
    VLC works, but you can't edit; exports fail or crash VLC.

    Forget VLC.

    This works.
