Timing of keyframe extraction

[ymartin-mw]

Haven't tried yet, but am wondering what is the best mechanism for doing less work for a given video to speed up?

Can we just skip N frames in the range here?

katna/Katna/frame_extractor.py

Line 98 in 5e2e570

for _ in range(0, self.max_frames_in_chunk):

I'm aiming to find the places of the algorithm that takes the longest time and try to minimize it,
Can a possible way to do so will be to consider a video as a collection of 1 frame for every 1 sec and then doing the same pipeline?

How long it takes to get 5-10 frames from a 1,5,10,15,20,25,30 min videos? with how many cores?

Thanks
