Hi, does anybody know how to slow down the playback of an avi file?

Thanks

Slowing it down will mess up the audio but if that is not important or you can add a different audio track, here is one way to do it. Create a new audio track that is longer than the video. It doesn't matter what the content is as you will delete the track anyway. Lets say you want the video to play twice as slow as the original. Make the temp audio track twice as long as the unmodified video. Copy the avi to the clipboard and then switch to the audio track and use Add Scaled. The new document will play the video half as fast as originally. At this point you can delete the temporary audio track and use Save As.. to create a self-contained file.
The result will no longer be a pure avi file but one that is embedded within a Quicktime Movie file. Since you didn't have to re-encode the avi the quality should be the same as the original.
This process will require that you have a registered version of Quicktime.

another way that's free and doesn't require making a new track (I'm not even sure how I would make a new track without sitting and recording dead air in real time), is called QTMutator. Also, if you want to slow it because of a sync problem, try Sync-Hole, which does not allow you to scale the audio track(s).

As I said, the content of the temp track is not important so you can extract an audio track from any movie and use cut and paste to make it the length you want the video to be.
