I am having an issue with FFMPEG. To be exact I'm trying to generate a number of 'meaningful' thumbnails from a video file. I have found this command on the internet:
ffmpeg -ss 3 -i input.mp4 -vf "select=gt(scene\,0.4)" -frames:v 5 -vsync vfr fps=fps=1/600 out%02d.jpg
Sadly it doesn't work for me, as I'm getting:
[NULL @ 0x86c2420] Unable to find a suitable output format for 'fps=fps=1/600'
fps=fps=1/600: Invalid argument
I have tried including "fps=fps=1/600" inside -vf, which resulted in only one picture being generated. What am I doing wrong?
EDIT:
This is an example of a full output:
$ ffmpeg -ss 3 -i video.ogg -vf "select=gt(scene\,0.4)" -frames:v 5 -vsync vfr fps=fps=1/600 out%02d.jpg

All I had to do is add -vf before "fps=fps=1/600"
