Hey there, while I'm aware there are workarounds, I just wish we could use imported video right in the program. It seems like that would be the most user-friendly option.
I plan to use CH for a puppet in 10+ minute Let's Play videos, and my After Effects simply takes far too long to capture face tracking data. I do use ManyCam currently, but I dislike having to manage the playhead in that for a video then pop over CH to start the recording. This puts my separate audio slightly out of sync with my face capture.
