Hi, I have a surface where a play a movie:background = "" 480))video = pygame.movie.Movie('video.mpg')video.set_display(background)video.play()And I have a black-white surface to use as mask:mask = pygame.image.load('mask.png')I want to 'crop' the video. Dont know if have to blit the video in the mask, or the reverse. Or to merge both into a new surface.How do it?
