Mocha AE terminated prematurely bug

[Brendon Murphy]

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?

[Brendon Murphy]

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.

I had this same error. So I went back to AFter Effects and took the MOV layer and duplicated it. and on the duplicate i clicked the “mocha ae” button on the mov layer to launch the program. once I was in Mocha AE I deleted a bunch of layers that I wasnt tracking and just kept the layer i was tracking (and the obscuration layer) and it didnt give me an error that time. (the reason it was ok to delete all those layers is because those tracked layers are still on the original MOV in my project, because I’m working off of a duplicate mov now in my composition)
