This will only extract an image every 5 seconds (per -r 1/5) - is this how it should be done and if so, why? Is this arbitrary? I see in processing.py it indicates only 1467 images from 20 videos were used to generate the image_kp_raw files which indicates this is how it was done.
In the readme the command for converting videos to images is as follows:
ffmpeg -i 00001.mp4 -r 1/5 -vf scale=-1:720 images/00001-$filename%05d.bmp
