Thanks for the response! It’s good to know what’s causing this, even if it can’t be fixed easily.
Mostly the individual trial recordings have had consistent frame rates within each one, so that if we expect to see 24 fps for trial_1, we’re seeing that in all of trial_1. But for some of these recordings, we also see variable frame rates within the same one trial video, so that about half the frames correspond to one duration while the other half correspond to slightly different duration. Is this caused by the same issue or is that a separate problem?
