Hey, thanks for this. I'm recording things with Nvidia shadow play and seem to get a lot of black flickering. I tried this solution however and I get no error message but the output file does not appear to be getting written. Any help would be greatly appreciated.:
ffprobe_cmd: ffprobe -f lavfi -i "movie=vid1.mp4,blackdetect[out0]" -show_entries tags=lavfi.black_start,lavfi.black_end -of default=nw=1 -v quiet
ffmpeg -i "vid1.mp4" -y -filter_complex "[0:v]trim=start=0:end=0.0333556,setpts=PTS-STARTPTS,format=yuv420p[0v]; [0:a]atrim=start=0:end=0.0333556,asetpts=PTS-STARTPTS[0a]; [0:v]trim=start=0.0662667:end=0.100756,setpts=PTS-
