Author of PySceneDetect here. The current implementation does exactly what you hint at, except instead of YUV, it considers deltas in the HSV domain (specifically differences in hue and color).

Other techniques being considered for future work include use of optical flow, background subtraction, and analyzing histograms.

From what I remember the Y (luma) component in a YUV video has more information than the other two components and it could also be extracted without the need to fully decompress the video (in mpeg compressed videos). Of course this info is more than 10 years old (I don't really do any video research any more) so I guess there should have been progress in that area.

This is indeed correct, I'm just using HSV instead of YUV, but the primary source of information is the luma/brightness component (although currently all 3 of the HSV components are averaged, so perhaps a better weighting may improve precision).

What if the shot is of two people having a conversation in a disco, with lots of lights flashing (stroboscope), etc?
