It was a good problem I think, it's going to make me better at mocha. I had to rewatch a couple of tutorial videos before I got it. While using adjusttrack, I was trying to keyframe the actual four planar surface corner pin points (the "poster corners") instead of the adjustrack tracking points themselves in order to compensate for the distortion caused by the cement beams passing in front of the camera. I was trying to reset the "master" keys for adjustrack every time I wanted a change, not realizing it was the tracking points that needed to be realigned, but that they can only be accessed if you are working in the adjustrack tab. Also, those keys I wanted were already being created automatically when I realigned between obstructions. Before I was playing whack a mole every time I made a change. The track between obstructions isn't perfect but I can massage the keyframe data in AE, and it's all already synced. Additionally, I had to reset the anchor point on the imported keyframe data so it all is brought in for tracking as opposed to stabilizing. Took me a while to figure that out too. Anyway, that was probably clear as mud, but maybe it will help someone. Mocha is amazing, but it's definitely a different paradigm.
