Generate videos snippets for interpretation: nothing happens

[slolignier]

Hi, I'm trying to classify mouse behaviors using DLC pose estimations. It went fine all the way to the generation of gifs. The app displays "Creating gifs from mp4s..." and nothing happens. I can't see new files being created, no message in the console or in firefox (streamlit). I've waited for 3 hours. The computer is quite recent (CPU i9 13900, GPU RTX 4090, win11 with conda) Any idea of what could cause the issue? Should I just wait more? Everything went quite fast from this point. Even the classifier was trained in a few seconds, which was surprising to me (but I do have a 451 Mb _randomforest.sav file created). In case it is useful, I've copied/pasted all steps in a workflow file attached. Many thanks for your help! WORKFLOW.docx
