Make sure you actually freeze the Rotobrush before rendering and al lthe propagation has happened correctly.

There's a button/ icon for it at the bottom of the layer window. I suggest you read the help.

Have you actually done the many Rotobrush tutorials?  It's all covered in them.  And I'm not talkingt the ones done by high school kids on youtube -- I'm talking the ones done by the pros, to which you can find links on this very web site.

This isn't an effort to brush you off.  Rotobrush is NOT intuitive to use, and covering its proper use is not the topic for a simple forum post. That's why there are tutorials.
