Is there any chance that you'll be able to implement rendering of multiple clips with audio?
SG6 has the same issue (as did SGNX) where if clips containing audio are rendered out using the full timeline, they won't render properly.
Each clip has the duration of the full timeline and puts a freeze frame at the last video frame of the clip.
This creates as issue for sync sound dailies because each clip must selected and rendered individually. Hopefully you will be able address this issue soon.
I second that request (or third, fourth, whatever...) Of course, it is a known bug that has been mentioned in a few posts from earlier this spring. I cannot understand why this would be so hard to fix - it imports clip audio and renders back to clips; just not if you use the metadata tags. Strange.
Would be REALLY USEFULL not to have to render each clip separately. Maybe the speedgrade gurus can come up with some kind of batch script or other workaround?
