Hi. Could you please upload sample? ffmpeg -i vid.mp4 -c copy -t 5 sample.mp4 to make short one.

libvpx doesn't accept such huge timebase denumerator. Clearly not a boram's issue.

You can change timebase of file without reencoding with something like: ffmpeg -i sample.mp4 -c copy -video_track_timescale 1000 fixed-sample.mp4 That works for me.
