Hi,
I know this is a bit late, but for future reference, here’s what I did (which I believe is a simpler method than those above:
1. Create the original sequence with all of the different shots.
2. Sync them, via Plural Eyes Premiere Pro, Manual, or other.
3. Nest the sequence within a new sequence.
That’s the normal stuff. Here’s what I did different.
4. In the new sequence, right click and select unlink to make the the video and audio tracks independent of each other. You now have separate control over video and audio (both are able to be switched independently).
*I have set keyboard shortcuts for quicker switching between shots (Cmd+Shift+1, etc.).
Hope this
