I've tried researching this but I'm not finding anything.
Using AE CC2017 on a Mac running the latest Sierra. Mocha Pro 5.5.1 plugin. I set up a scene in Mocha, track stuff, and get ready to do a remove using clean plates. I import a set of plates, do a test remove on frame zero, so far so good.
If I delete the renders, either one or the whole set, as I tweak and re-run the remove, I lose the ability to see the footage. Instead I just see all the matte shapes and such, and a yellow notice that (for example) "Frame 433 not rendered in clip 'Remove_Input'". If I run a single frame remove on any of the frames I can see that frame again (with the remove applied) but not the clip itself. I have to close Mocha and re-open it before the footage is again visible.
Perhaps there's some simply configuration I'm overlooking? I've gone through the video training and, as I said, did a lot of Googling but cannot find any mention of this particular problem nor how to correct it.
Many thanks in advance!
