This may be super simple! How do you add a shadow behind your actor which is in front of the footage/background?

Thank you!

MOD EDIT: Moved to the CompositeLab forum, given that the user appears to be using CompositeLab, not EffectsLab.

Can't. At least, there's no effect for it. You could raise the contrast on your footage and then use Chroma key, thereby only partly filtering out the shadow on the greenscreen. I don't know, however; I've never tried this before.

Or this. There is a tutorial somewhere in here, but I can't find it.

You can add shadow in your NLE, but only if it has that capability. But otherwise, Richard is right, the fxhome products don't allow you to add shadow. Maybe if you mask an area where you want the shadow to be, then apply the day to night filter... that might work.

Are there grade toolsets in effects lab?
If so, and you have greenscreen footage?
is it a person or an object?
you can 1st key out your greenscreen footage.
copy and paste the same footage above the 1st greenscreen footage.
animate it by moving the 4 corner quades, reposition it on the floor, table or wall or where ever you want your shadow to be.
add some blur and darken the footage using some of the options on the grade toolset and you're done

Effectslab doesn't do chromakey.

To make shadows you want to make a copy of your foreground, grade it to look like a shadow (ie, brightness all the way down, slight transparency and some gaussian blur), then warp it into position with the animation tools.

That's how we did the subtle shadow here:

Same concept was used in this video at around 1.33:

As the blue guy falls to the ground, you see his shadow appear beneath him. Without the addition of the CG shadow the composite didn't work anything like as well.
