I have been able to do stock footage with black backgrounds, but I can't figure out how to do it with white backgrounds. I have a lot of stock footage with white backgrounds and a few with green screen or blue backgrounds. how do I make these black or transparent?

I apologize if this topic has already been created. I couldn't find it anywhere, so I decided to make my own.

Sorry, I thought that link answered the question.

With white backgrounds, you can choose the blend mode to Color Burn, Darken, Multiply, Overlay, or Soft Light. You may need to fiddle with it, but it can work. Although personally, black backgrounds work better.

Also, I am not sure EffectsLab can do it as well as having CompositeLab or VisionLab.

When you click on your footage in the timeline (blue with the name of the clip/media) then in the upper right hand corner, you should have the "Object Inspector" available, and then click on the "Composite" to change the mode to said states.

No problem on the trouble. biggrin

Well I did click composite and it gave me a choice of "Add" or "Screen"
what do I do? cause when I clicked add it didn't really change at all.

I'm trying to have a blood spurt stock footage, and the background is pure white. just letting you know.

Simple answer:

You can't do that in Effectslab.

The ONLY exception is when your blood footage contains an alpha-map. If not, Effectslab can ONLY remove add / screen based stock footage (black background).


Without an alpha map, you can not do in Effectslab.
