How do I?

[Edward Troxel]

Do a search for “Green Screen” and “Chromakey”. You need to tape them in front of a green screen so you can key out the background.

Well……I have done the green screening. That has worked pretty well. Is there another way of doing it where you don’t have to do the green screening………..and if you do the green screening, how do I apply the drop shadow and keep it.

[Edward Troxel]

The shadow would be the catch but you *should* be able to take the original image, use 3D track motion to angle it properly, adjust the color as needed, and get something reasonable. Unless you use a colored background of some sort, you won’t see the shadow, though.

You could do it against any solid background like the clear sky. FX to Color Correction (secondary). Use the eyedropper to mark the background to be taken out, click “show mask”, make adjustment, turn off mask and then do the slider on the alpha.

If the subject is moving, chroma keying with a green or blue background is by far the best way to remove the background. To add a drop shadow to the remaining subject, click Track Motion in the Track Header, then check 2D shadow in the time line at the bottom. You can vary the size, colour and blur of the shadow.

If the subject is not moving, you can remove any background by using Bezier Curves in Pan Crop. If the subject does move, even slight movements of a “talking head”, you can use keyframes to follow this movement, but it is very time consuming.

Instead of chroma keying, there’s a compositing technique that you can try.
Look at the Two Cats From One tutorial for an explanation of this technique.
