Error with demo code moviestim2 on psychopy 1.90.3 (on windows OS)

Note that the key to speed here is not the size of the image in Mb (that’s a matter of how much the codec is compressing your images). The key is the size of the image in pixels because that determines how many values have to be passed to the graphics card by PsychoPy. For example: an RG…
