Description of the problem: I’m trying to implement a psychomotor vigilance test, which works in PsychoPy locally, but not when I try to run it online. In each trial the stimulus is a video of a stopwatch counting up to 5 secs, and the participant has to respond as quickly as possible.
Locally this works fine, with the stopwatch resetting on each trial, but online the stopwatch never resets, so after a few trials it just presents the final frame of the video as a still.
Previously I’ve had problems with setting the dimensions of the video but this seems to work OK now.
