I am looking for a tutorial on how to do chroma key effects. In particular cleaning up the images once the chroma key has been applied. Currently I have been placing black blocks around the image to clean up imperfections on the green screen. Also the halo around the images tend to pop out as well. Just wondering if there might be a good resource for reading or video?

I am currently using Movie Studio 17 Platinum.

Thank you in advanced.

Regards,

Joe
