Hi @lencriv,

We have seen a few problems like this occur when the video is not reliably seekable. Try reencoding your video and let us know how that works.

Thanks,

P.S. Also linking similar problems here for reference (namely Unable to load frame #366, KeyError when trying to run inference #630, and Encoding Multiple Videos using Batch File #710).

Great! I am converting this to a discussion in case others might find it helpful.
