I found one error, I missed the backslash, which I assume is to escape the comma. So now my code is ffmpeg -loglevel warning -i cine.h264 -c copy -bsf:v 'noise=drop=mod(4\,25)' cine-24.mp4. this gives a different error. [out#0/mp4 @ 0000019f6aba6dc0] Output file is empty, nothing was encoded I feel I am getting close to what I'm looking for, so where am I going wrong now?

I have looked at Downsampling / Filtering Data Stream with FFMPEG. I can see this uses noise=drop, so I tried the following. ffmpeg -loglevel warning -i cine.h264 -c copy -bsf:v 'noise=drop=mod(4,25)' cine-24.mp4 I tried various permutations of options but I just got the following error. [vost#0:0/copy @ 000002772d69c0c0] Error parsing bitstream filter sequence 'noise=drop=mod(4,25)': Bitstream filter not found Where am I going wrong?

select is not a bsf.

I think there is a way to mark a frame for not to be displayed by the player (without reencoding). As far as I know, it is not possible using FFmpeg. | |

Updated ffprobe output as the previous output was from a different video editor. The video editor used was Adobe Premiere Pro.
