I have read https://stackoverflow.com/questions/25774996/ , but "blend=all_mode=difference" is green. How do I get more colorful diffrence using blend filter?
Sample command is
ffplay -f lavfi "movie=left.mp4,split[a1][a2]; movie=right.mp4,split[b1][b2]; [a1][b1]blend=all_mode=difference[blend];[a2]pad=2*iw:2*ih[left];[left][b2]overlay=w[tmp];[tmp][blend]overlay=0:h"
using "hue=s=0", color chenges monochrome.
ffplay -f lavfi "movie=left.mp4,split[a1][a2]; movie=right.mp4,split[b1][b2]; [a1][b1]blend=all_mode=difference,hue=s=0[blend];[a2]pad=2*iw:2*ih[left];[left][b2]overlay=w[tmp];[tmp][blend]overlay=0:h"
