In an entire video
system, Qlab3 or 2 or a Green Hippo or Isadora ... someone has to do work. This just means that
you need to do the work prior. You'll have to either use Quartz Composer to corner pin or (and I would suggest this second option if you're on an older
system that cannot use
Qlab 3) render the videos already pinned. There are a lot of ways to do this; here's one that assumes you have the Adobe suite.
1) Open photoshop. Create a document that is the same size as your second
screen.
2) Next, drag your document to your second
screen and hit [F]. This will set your document into full
screen (you can
toggle this in the menu as well). Then make sure that your navigator is set to 100%.
3) Fill your entire
canvas with black
4) On a new layer, use a white brush to paint the set. Literally. You should see your
mouse on the set. Paint the area where you want projections white.
Here you might be able to stop. You've just created a mask. If you don't care about being geometrically accurate, you could make the white area transparent and save the document as a PNG. Then make this your first
cue in
Qlab on the layer "TOP", then
play all your cues on the layer "BOTTOM". The black will
cover the area that you dont' want to be seen. The transparent portion will let through the area that you do.
However ... if you need to do corner pinning
5) Pull this document into After Effects
6) Layer the photoshop document on top of your composition and use the Corner Pin
effect to adjust the video
7) Turn off the photoshop document and render, render, render, render over night
This will ask your
system to do much less work during your show, making it a better solution than Quartz Composer.
You can make adjustments live like you could do with Quartz Composer, making is a worse solution. But if you're careful to get it right the first time, then you'll be fine.
