intermediate result colors change in final result

[Andy Kiernan]

not sure this would help, but I usually just key to make a b/w matte then precomp and use that to matte out the original footage and colour correct that/ refine matte etc etc. Sorry if this is no help

Thanks for response… not sure what you mean “precomp”…

The other thing that is unusual, if I change the green spill key from “standard” to “ultra”, then it clears out spill and doesn’t effect color from intermediate to final….

I have exported a keyed clip with alpha channels in various formats using the standard spill and noting the color changes as shown, and the results show that the colors are exported with the original colors altered.

Still trying to get explanations..

Thanks

what I meant was pre-compose the keyed footage (keylight set to matte, so you see a black and white image) then use that pre-comp as a matte over the original clip. Also when using just keylight, I think its best to use ‘intermediate’ (then use spill suppressor and key cleaner), as ‘final’ uses its own spill suppression features which may be whats altering your colours

Keylight has spill suppression built in.

My guess is that when you look at it in intermediate, that spill suppression is disabled in the preview.

Then you’re adding another effect to do the spill suppression while keylight is not suppressing the spill (in intermediate), and you have things looking good with that other suppression effect.

Then when you switch to Final Result, Keylight is doing the spill suppression and changing the colors of the footage and that causes the other spill effect to get confused and that messes things up.

I’d either keep Keylight in intermediate (thus disabling it’s built in suppression) or remove the other spill suppressor. It would seem too many spill suppressors is not a good combination.

Just curious why when set on Ultra rather than standard… spill suppression doesn’t change original colors

thanks
