OS (e.g. Win10): Windows 10
PsychoPy version (e.g. 1.84.x): 2022.2.5
What are you trying to achieve?: Display a series of short movie clips
What did you try to make it work?: I have a loop going over a movie stimulus so that 80 short movie clips are displayed one after the other. My backend is set to “opencv” and my volume is set to 1.0. My movie clips are in an mp4 format.
What specifically went wrong when you tried that?:
The movies displays without sound and at a sped-up pace. Several movie clips in, the movies freeze and the experiment fails to response. It doesn’t crash so PsychoPy doesn’t give an error in the readout. The only way to exit the program at that point is to force PsychoPy to quit.
