TypeError when generating synchronized B-SOID video in analysis app

[pnair7]

I am trying to generate the side-by-side video in the analysis app, and am running into the following error when I click the "Generate synchronized B-SOID video" button.
A possible issue is the file input "Which file corresponds to the video?", as it's unclear to me which file is meant to be passed in here. (Currently, I am passing in the .h5 pose data file from DeepLabCut.) If it's important, I am running B-SOID using the Streamlit app on Windows.

TypeError: slice indices must be integers or None or have an __index__ method

Traceback:

Thanks!
