How to record participants screens on Pavlovia? (any help welcome!)

Hi all,

I want to make an experiment that records peoples screens as they draw a series of lines using the brush tool.

I have successfully managed to do this on the builder using the code:
win.getMovieFrame() (on each frame)
win.saveMovieFrames(expInfo[‘participant’] + ‘.mp4’) (on end routine)

However, this code doesn’t transfer well to Pavlovia - i get the following error: * TypeError: psychoJS.window.getMovieFrame is not a function

Does anyone know how else this can be done? I really need to get this experiment going ASAP!

Any advice welcome :slight_smile:
