Thanks, Michael.
I was following a workflow I found online, and which I tested with three clips in a simple sequence before I started. But I see what you’re saying about the way AVID tracks the clips, and the unnecessary added effort I went to keep everything the same, including the clip name.
I’m not sure anything I did should have resulted in such a wild deviation from the expected result, but I’ll definitely try “RELINK TO SELECTED” and see if that makes a difference.
In the meantime, I found that turning off AMA completely resulted in my AVID reverting into the calm, predictable, professional machine I’m used to working with.
So going forward, I might just have to take the time to transcode everything before I start my edit so as to avoid unpleasant surprises at the back end. (Though that just seems like a frustrating and unnecessary step, given the advertised functionality of AMA.)
To update the situation, in between crashes over the past 12 hours, I’ve been able to mostly transcode the sequence into DNxHD 444. So it’s only some 15 unruly clips that are causing me headaches, and I can probably reconstitute them somewhere else manually, and then reimport them into AVID and manually cut them into the sequence.
But this is all happening on a 2 minute piece. I can’t begin to imagine how upsetting this would all have been if instead it had been the feature I cut on Final Cut last summer.
I’m starting to think that AVID isn’t the solution to my R3D workflow problem.
Anyway, thanks again for your thoughtful response, Michael.
