Thanks, Dave, for the response. I do have 16g or RAM, but I will back that off. Sometimes, though, the answer can be quite simple: I rebooted my machine, and the sluggishness seems to have cleared up.
I will try your advice regarding sub-projects. That makes a lot of sense!
Once I have a shot synced with the proper audio, will grouping them be enough to hold them together? I’m not really sure what the limitations of “group” are?
Thanks again!
