  • Short description of error **

Mask doesn't match from VCE to preview.

Exact steps for others to reproduce the error

  1. Load in a movie clip
  2. Create a mask
  3. ISSUE: MOST of the masked area in the preview matches what I see in the VCE but some of it does not.

This makes masking, particularly animating masks EXTREMELY difficult, time consuming and arduous.

Unfortunately I don't know how the masking workflow works exactly. Could you create a screenshot/gif that explains what is wrong?

Also can you replicate the bug without an actual movie (maybe just with a color strip?)? That would make sharing the file easier.

Hey Jacques...take a look at this screenshot.

See how the mask should technically cut off his hair and the top of his head but it doesn't in the preview? Yet at the same time, the rest of the mask is more-or-less perfect. I should note that I made sure that the frames I was working on matched the frames I am seeing in the preview.

Hello,

I'm still not able to find a resolution to this issue and I don't see how I can test it with a color strip. There doesn't seem to be a way to open a color strip in the Movie Clip Editor.

Thanks!
