I don't recall ever seeing that message.
welcome to my nightmare.
I see it now. It goes so fast, I've never noticed. I'd say something is wrong with your install.
I'm just transcoding a dinky little clip at a time.
What are the specifics of the original media files
and your transcoding format & export settings?
Since you are only transcoding clips, have you tried
loading clips directly into Media Encoder instead
of sending them to the queue from Premiere?
They are MTS files I'm transcoding to 422 HQ for grading in DaVinci.
Since they're already in the timeline, I can't queue them as you suggest -- I just want to replace each clip with its 422 version.
