The PT updates have made it much much better. once you learn the controls you can really dial in the PT for like 95% of all the videos on the site, by
taking the default blue color:
Hue 50
Brightness 100
Saturation 100
and then slowly move the range to the right until it dissapears but doesn't affect the model.
Then locate the exact color of whats in the background majority and repeat the process.
I find you don't need 3 diff colors, it's overkill and in most cases makes the PT worse and more confusing. 2 seems to be a perfect balance. Some videos are just impossible if there's too much in the background, too many objects etc. But literally over 90% of videos work now.
