hi all.

well after a week of animating a mask, i was able to redesign my character in 3d behind a greenscreen and key them out.

what i am having issues with now is, i am using stock footage from demolition studios, their fires are on a black background. i have removed the greenscreen with the colour difference key, that has given me a nice subject. then i add in my fire, place an object mask over it, and relate it to the relative media file. i am however getting the black background of the fire media bleeding into my character, making her darker. i have attached a pic to show what i am talking about. how would i fix this?

What compositing method did you use on the explosion? Did you use an Add composite mode or use a key of some sort?

Hi axeman.

i found out that i had to add the composite method in, 'add'. so now it works fine. haha. i have been looking at a tutorial about another torch, and noticed that the user put on an 'invert' composite mask, then adjusted some of the settings. i tried that on comp pro but there are no settings to adjust, it is either turned on or off.

the problem i am having is that when i invert my character (who is in 3d) her clothes turn to a black color. do i have to apply a colour grade to make the colour of the actors skin closer to that of real life, so that when i invert those colours, the new colour is a grey colour, much like the image i have placed here in the first link. the second link is what i am getting.

It might be easiest to just alter the color of her clothes for those shots, so after inversion you still get workable greys. I'd recommend changing them to some shade similar to the skin tones, so that after inversion you get fairly consistant tones to the fire effect that you will add later.

Correct. I was suggesting the 3D shot be re-rendered and brought back into CompositeLab.
