Refining a spotlight

[ranbenazra]

Hello,

I'm working on a clip of a person in from of the theater spot light:

As the clip goes, the person in front of the spot light is moving - but always stays as a silhouette.

I need to make the edges of the spotlight sharp, so it will be a well defined circle.

​Any advise of how can I do it?

Thank you,

Ran

Simply create a circle of some sort and use a duplicate of the footage as an inverted matte on it.
