I would like to have video luminosity (and maybe saturation) to react on music tempo. And sure, possibly also some other similar effects. Is there some software for making such? I don't need real-time reaction, it is ok to do with batch-processing. Anc because music is self-made, it would be perfectly ok to define tempo, and have 'cuts' on given places. But not willing to do all those by hand, for example in kdenlive it would mean adding 3 keyframes to effect per one 'dip': normal before peak, peak, and back to normal.
Visualization software lebiniou would be one possibility, but it is not handling video with real colors, but instead working in 256 color space, and even there not 'normal colors' but mapping them to something else. And I think it does not have suitable plugin, but sure that is minor problem, I could code such
