Re: sweaty skin

I'll give it a go and risk being wrong..

If the footage isn't too compressed I think you have some options you could at least try.

I'd guess the sweat is reflecting a cooler blue highlight than the more orangy pink skintone..

Put a feathered shape isolation on the face that avoids the eyes and hair, select the highlights (now isolated by the shape) bring them down and warm them. Track the shape to the nose, and see how it plays.

I'd give the fx room a try as well, build a tree to selectively blur that range of skintones. Only use this if it really works well though, as I believe using the fx room still results in a resolution drop from a buggy deinterlacer.

Both suggestions will only give subtle results before becoming obvious, so go sparingly.

Good luck!
