Color pass ala Sonefields download and Chromakey techniques in Vasst article.

How's that for an abstract subject line?
I was just wondering after watching Stans Lip vid and reading the article on the vasst site about chroma keying. if when doing a color pass if apply the Chroma blur and possibly a 2nd sec color corrector(for saturation prior to the sec CC for the color pass) helps at all.
Does that make sense?

It never occured to me to post the veg file used for the download test clip...

So I added it on that page...

Excelent Stan ! thanks for the .veg. It is interesting that you used those filters ie saturation instead of sec color corrector. Is that becuase you are not using V5 but something older ? Or because it works better than the sec CC method for your uses. I have saved the filter settings as "Sylvies lips" as a reference to learn from.
I see you did use the chroma blur so I was on the right track.
Your to cool for School.

Kanst I'd like to see yours but I dont have a way to uncompress rar files.

I second everything epirb said, right down to the .rar files.
Stan, I'm being dense it appears. I turned on and off that Chroma Blur and watched closely as my eyes could at t 2am. I couldn't see what the CB was doing.
And... how did you get that combination of FX?! I would never have known to use the Saturation tool to eliminate all but a colour. Absolutely brillient!

It's all just tinkering with filters....little of this...little of that.

The Chroma Blur DOES do a bit of smoothing out but you just don't see it in that one frame still. When she's dancing around ( and bless her for doing so ) it becomes more apparent what it's doing.

You're gonna see a LOT of this kind of selective color isolation in the next while. It's been used a lot in commercials but now that Sin City is such a hit, you're gonna see lot's of high contrast, almost monochromatic stuff with isolated colors.

I prefer this method as to using masks but each different shot needs to be treated differently. I applied the LIPS filter chain to another shot and it worked but not as well. Bit of tweaking and much better. Remember too, you don't have to use the color you end up with either....put in a secondary color correcter AFTER the chain and turn her lips to what ever color you want by rotating the hue.

Robert Rodriquez ( director of Sin City ) was having trouble with the character Yellow Bastard as the yellow makeup tests showed a conflict and contamination with the green screen .....solution ? He painted him blue instead and then in post just rotated the hue......heh.

I love this stuff. Does it show ?

WOW! It's 1st time in my life that somebody has no WinRAR (http://www.rarlab.com)
OK. Try ZIP
