I'm ready to make a purchase, but I'm stuck between FXLab and CompositeLab.

So, my question is: can you do green/blue screening effects with EffectsLab, or will I need Composite Lab for that?

You'll need CompositeLab for green/blue screen work.

What exactly does the masking feature do then? I thought that meant a greenscreen type thing? confused

Masks allow you to draw a shape over an object, and then either keep that shape and make everything else transparent, or vice versa, allow the shape to turn transparent and everything else will remain visible.

So, yes, in EffectsLab you could draw a mask around the actor that you want to keep, and everything else would disappear and reveal the object below. But you'd have to draw this mask on every single frame of your video!

CompositeLab has support for masks but also contains "matte filters": Specific tools for green/blue screen work, such as chroma keying. This allows you to select a colour (e.g. green) and automatically remove all green from your object. So if you film an actor against a green screen, then all the green will disappear and only your actor will remain.

Masking is designed to aid compositing and interaction between elements. For example, if you wanted a lightsaber to go behind an actor, or if you wanted a particle effect to go behind a tree. It's a vital part of any kind of effects work.

However, for general compositing work, CompositeLab has many more features designed for compositing multiple layers of different sources, including greenscreen facilities, garbage mattes etc.

It depends primarily if you work focuses on general compositing (CompositeLab) or cool visual effects (EffectsLab).
