Unable to sync experiment with large files to Pavlovia

Online experiments

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Sequoia 15.5
PsychoPy version (e.g. 2024.2.4 Py 3.8): 2025.1.1
Standard Standalone Installation? (y/n) If not then what?:
URL of experiment: Can’t get it to upload so it is just an empty repository
Do you want it to also run locally? (y/n) no
What are you trying to achieve?:

I am trying to get a differentiation task with 162 videos that all have visual noise to upload to Pavlovia through the sync function.

What did you try to make it work?:

I tried using the sync function in the psychopy builder and I received an error saying that the sync failed because the local end hung up, when trying again I got an error saying:

-m Push initial project files
stdout: ‘On branch master
nothing to commit, working tree clean’.

I then tried to push my experiment folder to Pavlovia through the terminal and it froze at 23% while writing the objects to the repository.

The experiment folder contains 3.48 GB of files and my experiment has to be run online. Is there a better way to run it online? I feel like everything I try I run into an issue with the size of the files.

I think PsychoPy is now set to be able to sync up to 500Mb.

You could try overriding this using the method found here: HTTP 500 error on initial git push

How many MB of video files will each participant see?

I have increased the limit to 500 Mb but it is still too big. Each participant will be presented all 162 videos which add up to over 3 GB. The videos are so large due to the visual noise that was added to each frame.

This limit is set to 500Mb in the current version so you didn’t increase it.

I don’t think you will be able to run an experiment with that memory load online. You could try by increasing the limit to 5GB but having the files on Gitlab doesn’t mean it will run. I recommend you try a cut down version first.

Hello @Chase

You should bear in mind that your participants will need to download the films. Depending on their network connection, downloading over 3 GB could take some time.
