What happens on that frame where it crashes? Does a layer begin there? Does some keyframed change of properties occur?
How are you doing this render?
Is it through the Render Queue? If so, what format and codec are you rendering to?
Is it just a RAM preview? If so, what happens if you just put your timeline marker over the offending frame?
Is this an 8-bit, 16-bit, or 32-bit project?
It's a render preview, not via render queue. On my limited keyboard I use the option + 0 command to preview.
Nothing significant seems to happen on that frame. It's a frame just before a bunch of keyframes.
The project was set to 32 bit. I just opened it and tried it at 16 and 8 respectively, stepping through the frames. When I got to the offending frame it crashed with the error message, both times.
Also, it is a precomp, but I am inside it so that shouldn't be an issue...
Any chance we could have a copy of the offending project to see if we can replicate the problem?
Hi, I reduced the project and collected it so it's just the problem comp. I have an archive I can send over, how should I go about doing that?
Double-check that the newly reduced/collected comp still has the same crashing errors on your end.
Then you can upload the project to any place you use to share files. You could do FTP on your own site or you could use something like Dropbox.
PS - I double checked, still having the same issue.
The problem is in Mask 1 on the Head layer. Delete and redraw/re-animate that mask.
Why are you drawing masks on solid layers for animation? That stopped being the right way to create graphics in After Effects seven years ago, when we introduced shape layers. I strongly recommend using shape layers for the kind of work that you're doing here. Also, I just checked, and copying and pasting your mask paths into shape layers path makes the problem go away, so whatever bug there is there is just with masks on solids.
To learn shape layers, go through Andrew Devis's materials in this series:
