Movie not playing in Bulder


I’m sure this is a really simple problem but related posts don’t seem to have the problems I am (though the googlegroups approximated it). I am trying to put a movie into my experiment and have it in a .mov format (though this problems exists with .avi as well). When the movie component starts the video does not play - it is just a blank screen. I don’t get any error messages and the experiment terminates if I put a limit on screen duration.

I am using PsychoPy2 v1.90.3 and I can’t find the movie demo from previous posts to see whether movies will run in my PsychoPy.

I’m sure this is an easy thing to solve but I just can’t quite seem to tweak according to everything posted so far.

Thank you,


Sharing your code here could help. Could it be that you set the video display to something small/in the corner or on a different monitor if you have a second monitor?

I have included the code below but all I have in the builder is the movie showing for 2s without any other components. I have a central presentation [0,0] and size [1,1] which seems to be quite large for my screen with other text or polygon components. All I need to do is present a movie for no more than 35 seconds but have participants guess when it has been playing for 10, 20, or 30s. I will have a single button response.

It really is simple!
