I’m trying to make it so that participants watch a video clip before taking part in an experimental task involving pressing a button if they want to take one action and pressing another if they don’t. The experiment will play the first video clip and then show the first trial of the task before crashing.
I get given the following error:
C:\Program Files (x86)\PsychoPy2\lib\site-packages\psychopy-1.84.1-py2.7.egg\psychopy\visual\movie2.py:352: VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future

I’ve tried using different video file formats and renaming the files. I’ve even tried taking all the videos into one script and seeing if they’ll play, but then I get the same problem where it will play one video and then I get this:

Is there a way to fix it so that the video files will play and the experimental task won’t crash? I’ve added a copy of the script below. I’m using a Windows-10 64-bit system and the latest version of PsychoPy.
I’ve tried movieStim, movieStim2 and movieStim3 but I’m getting the same error still. Do you have any other suggestions or understanding of what the error code means?
I just looked at your code and you’re trying to load the video from the disk on every frame (ie every time the screen updates you start loading the video again from scratch!). Load your movie at the beginning of the trial or beginning of the experiment.
Any reason you’re not just doing this in Builder (which wouldn’t make that mistake)?
I am designing this in Builder. Assume I know next to nothing, could you tell me how to fix this please? It’s meant to be that the video plays then the trial begins, and that’s the way I designed it in builder mode (I think).
Ah, because you sent a .py file I assumed you were writing this in code. If you’re doing it in Builder then you’d be better to send us the Builder experiment file (the one ending psyexp that you open in builder).
Try this - I’ve isolated just the video component and randomisation loop. I’ve also added the spreadsheets needed.
Thanks,
Josh
P.S. I don’t suppose you have any idea of how to record if a mouse click is the correct response in an output excel file? i.e. if the participant correctly clicks left on the mouse when they are meant to.
Sorry for the delay. My internet router was one the ones that was taken down in the TalkTalk hacking so Ive only just been able to respond. I’ve attached an updated copy of the file (no idea where the videos went).
I didn’t realise that was the case. On my screen the resolution is in the size box, not the position box. Could you perhaps send a screenshot of what it looks like on your end please?
I opened your file in my work networked PC (Win7) and it still shows resolution and position misplaced.
I also think you need to change the Movie file from constant to set every repeat (I may be wrong about that though).
I run your exp by adjusting resolution, removing the images and their associated code and using the wildlife.wmv video file found in windows movie folder and it ran just fine for me.
