Green Screen Shoot question
Hello,
I’m doing a green screen shoot in the next few days. It’s going to be shots of people inront of a greenscreen that will serve to populate preexisted plates I have been given.
I’m shooting with an HVX200 and working on a G5 in Shake and After Effects.
Here is my question, is their some kind of software I can use that if I feed video out from the HVX into the G5, I can preview what I’m shooting live with lets say 50% opacity and have my plate underneath so that way I can make sure that the perspective I’m shooting from will match the perspective of my plate? It would also be nice to be able to scale and move the live feed ontop of my plate, since the subject or subjects in front of the greenscreen will be majorly scaled down to the plate later in post since it’s a vista shot.
I’ve trying to find info about this but couldn’t find anything for the life of me. Any help would be greatly appreciated.
Major thanks in advance

You’re kind of doing things backwards, which is the hard way. Typically, actors are shot first on a greenscreen stage with tracking markers and the background CG is created after the fact to match the perspective. You might have more success by changing your workflow – there’s lots of info and software dedicated to 3D matchmove. Check out SynthEyes and PFHoe Pro for some inexpensive examples.

Not necessarily. Sometimes you have to work with existing plates as was done here:

I do the same thing for my own show, although the process isn’t nearly as sophisticated nor complex as with Stargage’s examples.
When using existing backgrounds, it’s essential to match perspective along with direction and quality of lighting. Using a transparent overlay can help speed the initial setup somewhat. The final lighting and camera setup is best done with a “scratch” or rough composite on set prior to actual filming.
That said, if anyone has a answer for Ron’s question, please share. I could use something like that, too!

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Might be a better question on another forum. Keep in mind that we are editors, only a portion of us shoot too.
