If you mean to make a chroma key with a green background, the first thing you should do is upload a sample of your clip with at least one screenshot. This is a relatively complex technique that needs to be handled well at the time of filming, good lighting, good recorded footage, etc. There are good tools for Chroma Key but first show us what, so we can try to help you.
