If i shot a single actor against a blue/green screen, would i be able to resize his height when i composite it on other footage? Im building miniature sets for larger locations as some of you may know and so i need to have various people walking around and interacting- i'd rather have live actors than CGI.
Thanks for any replies!

If you use CompositeLab or VisionLab resizing and repositioing is easy. Check this out:http://fxhome.com/support/vidtutes/?t=1&f=%2Bcat%3A1&cat=1

Ok, i have a question, can you change an actors hight, but not the canvas size some how? Like a hobbit or something?

You would have to Isolate the actor, most easily by using a greenscreen. But you could mask around the actor to isolate him (Very tedious). But no, you can't have a shot of two people and then just shrink one of them withought messing everything else up.

To do it without a greenscreen you'd have to film the scene empty of actors (to create a background plate) then film your actors in the scene.
You could then have the empty background plate on one layer and overlay other copies of the clip in which you mask off everything but the actors so that you can resize and overlay the clip. You can have as many copies as you want so you can isolate each actor.
This would take a loooooong time
Masking off each actor frame by frame would be a lengthy process - you are basically doing by hand the job that Comp Lab does automatically if you film in front of a greenscreen.
I know that Sollthar's tutorials at the No Control Cinema website do use a technique where he paints out the background around his actors in Photoshop to create a matte so he would be able to give you more advice on how long it would take!

For LOTR, whenever the hobbits appear to seem smaller, its either a trick of depth of field or they use a greenscreen. The depth of field thing is where the hobbit is actually farther away from the camera than the other actors, so he seems smaller. But aside from that, to achieve this effect you need a greenscreen.

So it is possible with composite lab then? Because I'm getting effects lab and composite lab.

Yes, CompositeLab is made for Greenscreening (Among other things, like Grading, etc.)

So if I'm understanding this correctly (Using the example for the shot I want to do), I can shoot my actor in front of a green screen from say... 20-30 feet away, and then put that green screen shot into another background to make it look like my actor is roughly 100 feet away from the camera? I can resize my green screen shot into the background itself?

Yup, any media layer can be resized and repositioned however you'd like.

Well, that's great news! It's going to allow me to possibly drop in hundreds of additional zombies to some shots I've done. That's going to make some of those shots *much* more dynamic.
My green screen is about to get quite a workout.
