FPS instead of number of frames and distance between frames

Anastazja Ostrowska

i don't know how many frames my video has and i don't want to put in too many so it would be easier if you could just put in how many fps you want

Hi / Cześć
I don't quite understand what would change if you'd supply extraction rate in FPS. If I understand correctly you want to specify that from some starting point you want to extract, lets say 10 frames per second.
How is that different from specifying 100ms distance between frames? This is the definition of 10 FPS.
Then my other question is: when to stop? The extraction rate is only one parameter, we also need to know when to stop. Or do you mean this should be f.ex. 10 FPS until the end of the movie? With longer movies this can lead to browser crashing. All frames are kept in RAM. For more advanced extractions like that you can have a look at https://ffmpeg.org/ -- it can extract frames directly to the hard drive and therefore doesn't have the same RAM limitations.
