Roto Brush mask is different after rendering
I roto’d out a person in room on a ProRes 422 clip. The mask while in AE stays close to the person and looks the way I want it to. Once I render though, the mask is completely different. It’s trails behind the person as she walks through the room. To trouble shoot, I’ve taken off all of the refine matte options, exported clips individually and with other layers, exported with and without an alpha channel, nothing makes the mask look the way it does in the actual project.
Please help! Thanks!

Are you freezing the rotobrush on each clip?

You’ve referred to masks a couple of times here. Did you actually create masks in some way, or are you just referring to the matte created by the Roto Brush effect?
Tell us more about your composition, source footage, and exported movie including frame rates. Are you working with interlaced footage? If so, did you separate fields? Did you get a warning when using the Roto Brush tool about frame rates?

Meant to respond to this earlier. Freezing solved it! I’ve rendered out after using roto brush before without freezing, and the renders looked fine. This is a great thing to know. Thank you!

I have the same problem except that the render is still wonky after freezing the selection. Any ideas?

I do have a frame rate warning that the footage is 29.97 and it wants it in 59.94.
I’m working with interlaced footage that I haven’t separated fields on.
The footage is 720×480 29.97fps, the composition is 1920×1080 23.976fps.
Basically it’s all wrong. And on top of that when I bring it into After effects it looks like after effects stripped about half the pixels away. There is a severe amount of deterioration in the footage that we don’t see on the raw clips (prior to any masking or even placing it into a composition). -
Just wanted to say thank you for posting this. I spent about an hour trying to solve the issue for a video I needed to release today and came across this. I had no idea about the freezing technique.
