Playing around with the demo for 2.1, and very interested in possibly picking up this package especially now that they've announced Combustion 3 will be available for the Mac.
One question I have involves what essentially is a "clean plate" against live footage whose lighting varies.
What I've got so far:
* Track the cleanplate to a feature on the background so that it follows the camera's motion.
* Mask the cleanplate so that the areas that need "cleaned" are the ones that show through.
So far this works beautifully. Now, when the lighting (an ourdoor scene with clouds moving across the sun... how inconsiderate...) changes in the live footage, the color of the cleanplate no longer matches up with the color of the live footage.
Is there a way to automate the color correction of the cleanplate so that it follows something on another layer?
Ideally, the "offset" feature of Discreet Basic CC could be used: the "source" point is identified on the live footage in the same frame as the cleanplate was taken from at a pixel that appears in both the original footage AND the cleanplate. The "target" pixel is this same pixel on the cleanplate.
If that would work on a frame-by-frame basis it would color correct the cleanplate on-the-fly to match the variations in the rest of the live footage. For relatively small areas of footage this works really well... but keyframing the CC isn't doing the trick. I need frame-by-frame control!
Is there a way to do this?
And... if I'm approaching the concept of removing an object from a scene all WRONG, any pointers would be very appreciated.
