You have not told us what you want to change the background without fixed color into . Do you want to make it the same as the background with the fixed green/blue color, so that basically the whole image looks pretty uniform? Why don't you first read this, then upload a frame of the video so we can see it.

Dear Ser, Madame,
Since a video are slices of images (=frames), you could try first extract all frames from the video. How this could be done, can be found in for example this MathworksAnswers discussion. Then you could try to modify each image. A discussion about this topic can be found in this MathworksAnswers discussion.
Good luck! Christiaan
