Is it possible to have Psychopy’s
MovieStim play only a certain spatial percentage of a movie file?
I would like to be able to show 0-25% of the x-size of a stimulus, then 25-41% etc. It is not feasible for me to manually crop the videos, because I need to control the crop coordinates at runtime.
I am currently using this code, and I was hoping to get the effect I want with the
MovieStim.size attribute somehow, but that invariably controls the size of the entire movie.
