I'm not really sure I understand what you are meaning. I would definently recommend greenscreening instead of blackscreening. But a lot of downloadable stock fottage is blackscreened. If you want to use this in your movie, then set the blending mode to "Screen" if you're using After Effects (or similar). Set the blending mode to "Add" if you are using Chromanator. You can change the blending mode in Chromanator by right-clicking a clip on the timeline, and then picking properties.

"Black screening" actual objects like cars etc. will never work because of the shadows and highlights of the object. It will work very well on explosions and flames though.

Is there any other way to "blackscreen"? I usually use it for adding in light effects, but because I use imovie, i have always wanted to use it for text (have basic text over black) and then animate it in chrominator. I guess if was just white on black I could adjust it to be non transparent.

I believe they used blackscreening in Hollow Man for some of the smoke and/or water effects, but I am not too sure.

You can film infront of a blackscreen and key out the back, but this won't be nearly as effective as using a greenscreen in terms of filming people. Though if you're filming muzzleflashs or explosions for stock footage then you just film it infront of a blackscreen for the best results.

(I think)

Well, I did a little research... the blackscreening idea was used for the scenes in Hollow Man that were completely submerged under water. They painted Kevin Bacon's entire body black because it gave the best contrast compared to the rest of the environment.

what I wanna do is after I cut out an object instead of putting it in a scene and rendering right away I want to save so I can use in clips in the future so I figure render over nothing then it'll be the object and black all around it then just cut the black out later whenever needed

It depends on what you're rendering, and where from, but you should look into rendering with an alpha (transparency) channel. I'm not 100% clued up about this myself, but it's certainly something that you should be able to find information about.

Hope this helps smile

Cheers,

I think what you're looking for is a Luminance Key.

I don't have Chormanator, so I can't say if that program supports Luma keying, but I think that is what you're looking for.
