Use chroma keys
A challenging part of creating a good chroma key is shooting the chroma key video, and in
particular, using a good, well-lit background that provides a uniform color to remove. A wide
variety of specialized chroma key background options are available, from chroma key paint

important to use the best camera you can access and avoid using a highly compressed video
format such as DV or MPEG-2.
