Error playing 50 FPS video files

Description of the problem:
I’m trying to play a 50 FPS movie stimulus online on Pavlovia. The stimulus periodically becomes fragmentary and discontinuous. I assume it can be caused by Pavlovia frame rate preferences for videos. Could using a 30 or 60 FPS video solve this issue, or there is some different problem with this experiment?

I use Mozilla Firefox on Windows 10.

Thank you in advance :slightly_smiling_face: ,
