Thanks Gyan! The file is exactly 3600 seconds long and I take 4
frames (20%,40%,60% and 80%).
Adding /-t 2900 -skip_frame nokey/ would be the right thing to do?
Will that be fast even with a 10Gig video file?

Hi,
I run the code below to produce a tile thumnail from video files. That
seems to be very slow on big video files. Anything that I do wrong, or
I could improve to speed up processing?
ffmpeg -ss 720 -i $input_path -f image2 -vframes 1 -aspect 4:3
-filter:vf
