I recorded an video with an iPhone SE, iOS Version 11.4.1 (15G77).
I want to extract as many individual and freeze frames in best available quality. I guess i can get a max of 30 freeze frames per second?
With ffmpeg -i /tmp/IMG_1234.MOV -r 1/1 /tmp/$filename%03d.bmp
i get only one freeze frame per second.
What do I have to hange to get as much different / individual freeze frames as possible?
Next step would be to extract freeze frames not for the whole video but only from position a to positon b. For example all frames from 00:05 to 00:10 (mm:ss).
These are the infos from ffmpeg about the file:
