I recorded a video and I got the ratio of the recording program off so I have small chunks of my desktop in the video and would like to remove it. I want them gone for the entire video ~9 minutes.
The badly made arrows are trying to show what I mean, and I forgot to include the bottom and top. I've asked on a bunch of other forums so far and I can't get a good answer.
Use either the pen tool or the rectangle tool to draw around the part of the video that you want to keep (alternatively, draw around the parts you don't want to keep and change your mask operation to subtract).
However, this means there will still be black bars on the side of your final render.
I found out how to render and fix the video now. Thanks for all your help!
