Using ffmpeg to extract every n frames from a given range of an m2ts video

[joshmccraney]

Hi PF!

I have a video titled myvideo.m2ts that is 2 hours long at 60 fps. I would like to extract every second from 54 min to 55 min via ffmpeg. It looks like I would execute something similar to this: ffmpeg -i myvideo.m2ts -r 1 output_%04d.png except this will run the entire video. Any help is greatly appreciated!

Use the -ss option before the -i option like:

ffmpeg -ss 3240 -i myvideo.m2ts -r 1 output_%04d.png

as described in the online manual: https://ffmpeg.org/ffmpeg.html#toc-Main-options

Edit: oh, you only want 1 minute: use the -t option as well:

ffmpeg -ss 3240 -t 60 -i myvideo.m2ts -r 1 output_%04d.png
