Question

Blending Paper Stop Motion Animation With Background

Hopefully you can get a sense of what I'm trying to do from the gif in the link below. I want to blend the animated clip with the background.

Since this was shot on paper it's not a perfect, even, solid white. There's a natural gradient to the left and right of the frame where there's shadow from the lights used. So simply using the pipette tool to match the colour of the background to the paper wouldn't work.

I've tried color keying it with some success, but as I slide the threshold up, I start to lose parts of the logo just as I achieve the desired effect (see below).

 

 

While I'd settle for a blend similar to in the image above, if there's some way to get the background colour to match natural gradient of the animation rather than the other way around, that would be a better outcome.

 

There's three tracks at present. Listing them here if it helps:

V3: is the digital logo

V2: is the stop motion animation (P1160810.MP4)

V1: is a solid white background

 

 

Any ideas you have would be very much apprectiated! Thank you 🙂

Try making two opacity masks: one for the rotating object and one for the hand.

Another alternative is to rotoscope in After Effects.
