In response to a request for more information on the Apple Discussions Board, I sent the following reply:

The clip is a DV clip of an an egret flying. I had applied Analyze Motion from the Motion Tracker folder and manually entered a number of keyframes. I can’t recall what other actions I took, if any, because I was just playing around trying to learn the program. I thought that if I went back to the autosave versions of the motn file, I might be able to figure it out, so I reloaded one and it reproduced the problem as before.

I then moved the motn file from the Autosave folder into a “Motion Problem” folder while assembling all the relevant elements for submission (to?). When I reload this file back into Motion from there, the problem is gone. Nor does it reappear when I put the motn file back into autosave and run it from there.Very bizarre!

I have made a jpeg of a comparison of the audio waveforms of the original clip and the problem output clearly showing the nasty artifacts but don’t know where to send it.

Until I reproduced the situation from scratch (short term memory okay) on my iMac, I thought the problem might be related to the random audio popping I’m getting on my Mac Pro. I suppose I had best just keep my speaker volume low and hope that it doesn’t happen again.

The problem is serious, but elusive.
