Staying with our BorisFX friends. Yes, I know catchy subject line to catch your attention. But this is one is definitely worth the watch:
BorisFX livestream Roto Masterclass.
A few call-outs worth watching:
Discussion on roto future & AI: 35m21s
Discussion on why bezier is not best choice: 1h02m06
Discussion on roto of moving objects and why we all do it wrong: 1h37m16s
Both Carlos & Marco make interesting points why AI is not solving our roto needs anytime soon
And the third section above - you (me included) may have roto’ed motion blurred shapes wrong all along. Forget feather. There’s a better solution.
