I am using green screen from Envota but it has white tracking marks (x's) on and I need to remove them. Any ideas how you do it?
Never heard of Envota. What is it? Maybe some sceenshots on how these white markings look like...
I think Hannah means Envato
You can use masks with the opacity in the effect controls panel, Notice that it's not an easy task if the subject crosses in front of those marks
Can you post a link to it?
If you have access to After Effects you might want to try using the Keylight with Spill Supressor effect. It works very well in situations like this.
