I've been playing around with Effectslab Pro lately and I notice that stock footage with a black background automatically has the background erased...which is nice. However, there is some footage on Det. Films that I'd like to use...it just has a white background instead of black. In my Effectslab Manual it lists all the different composite modes Effectslab can do but I can't seem to find them anywhere? Can anybody help me?

Click on the media bar. The composite types are under the toolbox option.

My composites don't work on white? Only black? Am I doing something wrong? Because on pg. 100 in my manual it lists Normal, Add, Color Burn, Color dodge, Darken, Difference, Exclusion, Hard Light, Lighten, Multiply (which is what I was told to use on white BG footage!), Overlay, Screen, and Soft Light. The only ones I see there are Add and Screen...Help please!

A wide array of composite modes are available for Effects Objects created in EffectsLab. As far as imported media goes, though, Effectslab is optimized to work with stock footage on a black background. The Screen and Add composite modes are built in to the program for this purpose. It is not, however, a comprehensive compositing package. CompositeLab Pro can easily do the sort of compositing you are after. If you have a quality editing app, chances are good that it could handle that type of compositing as well.

My editing program can do white, black, blue and green. But only the Blue and Green look remotely good. Effectslab is now my choice for black I was just hoping it would do white too...is there anyway to change the background color of the white stock footage to black?

Not really. Typically white is used specifically for the types of effects that black doesn't work as well for.

If your editing program can handle keying like that, to any degree, chances are good that it can change the composite mode on a clip to multiply. You might have a look at the manual to find out for sure.

It can't do multiply, I checked. It can do reverse Luma, which is the only way to remove the white background in my editing program. But the bullet hits I tried to use looked really bad. Each of the different things of dirt had a square of white around them.

BTW, I use Premiere Elements.

Are you trying to get rid of the white beckground? If so, what you could try doing, is inverting everything so that the white inverted to black is removed, and then after rendering, just invert everything back.

That's really good idea! I'll try that and reply with what happened.

EDIT: It worked awesome! Thanks man!
