It cut off all other good frames together with the first bad frames.The script worked for me but the problems are: I used the script below (reference: to first auto detected black-screen frames using ffprobe and trim them out using ffmpeg. I am working on an ETL process, and I’m now in the final stage of preprocessing my videos.
