Re: [Avid-L2] Re: Transcoding Gotcha I found out the hard way with Convert Audio Checkbox

 

I've given up on adding tape names to AMA linked clips, although I do
typically add a custom column to track the card name, just in case.

I could be wrong, but I think in earlier versions of Avid, timeline dupe
detection didn't work unless there was a tape name associated with a
clip. Adding tape names could also help disambiguating duplicate clip
names.

Cheers,
