Do you have at hand a 4K mkv that is known to work to get 2 seconds from it? I used the following command to extract 3 seconds, where `-ss 2665` is the start second and `-t 3` is duration

ffmpeg -i input.mkv -ss 2665 -t 3 -acodec copy -vcodec copy output.mkv

No, sorry, I don't have any downloaded files here, don't even have the time to watch "regular" TV, or my stack of recordings...
