Mocha AE terminated prematurely bug
Trying to track a few cell phone screens but getting a “Tracking layer terminated prematurely” error on each frame. The only post I found online is from 2016 and they say they were aware of the bug and working on a fix, which evidently hasn’t arrived yet.
The suggested solution is to save close Mocha and open again but it’s not working.
Any ideas on how to fix this?

I’ve had funky issues sometimes if a bezier handle is twisted… sometimes you may not even realize it. I’d try setting up a new mocha project and draw a brand new mask. Keep the shape as simple as possible – a single rectangle if you can.

My spline is pretty simple, not a rectangle but I do not have curved or twisted handles, pretty much irregular polygonal shapes and that’s it.
Could it be excessive blur?

That could certainly do it. If there’s really fast movement, you may need to skip that section in your track and just adjust that part manually in comp. I tend to do separate tracks for each “good” part, then parent the track nulls to each other in AE. Parent the Burn-in to the last parented null, then adjust it manually on top of the track as needed.
Another good trick – instead of tracking the raw footage, create a denoised hi-pass plate with enhanced details. There are a few tutorials out there for ideas on how to do this.

That’s a great idea, I’ll try that, although I don’t think it’s the issue here. At some parts, the footage gets really blurry. I’m going to have to manually track those in comp.
Thanks for your help.
