I'd been experimenting with the possibilities of slow motion and how to achieve that slick, ultra slow look in stop motion. And after a while of testing, I decided to make a short film to showcase the effect. It is a spoof of all those fancy perfume commercials you see on tv.
I've combined green screen, with miniatures, live action, and CG backgrounds. The puppet was animated at 30 fps, in incredibly small increments, then reduced to much slower speeds in After Effects through combinations of 'Timewarp,' 'Time Remap' and frame blending.
All effects were accomplished in After Effects, with live action elements, such as fog and rain, composited into the shot.
For a wide shot, my uncle built a 3 ft, wooden model of city storefronts, which I decorated with miniature trees and lit with X-mas lights. I also used a fog machine to catch the light from the windows and obscure the background. After it was filmed, I animated the puppet on green screen and stuck him in the shot.
Set sounds close the the 1:24 scale I use to get wider shots of street scenes. I couldn't tell, it could have been 1:6 from the photo!
I could have shot the monster entirely against greenscreen and put the house on another layer in the first place, but I liked the shadow appearing on the house. Tied them together better. Trouble is, the shadow also causes warping! So may have been a bad call.
Possibly I could still roto the monster out by hand, and forget the shadow. Or stretch the house and shadows with simple frame blending like you say, that looks ok with soft-edge things. But I would have problems with the actual hand area where the Frame Blended hand and the Motion Pixeled hand don't match. I've painted some of the warping out (frame by frame by hand, not tried Rotobrush), and may just add smokey effects over the top to confuse the issue, and call that good enough. I need to try another shot with the tentacles and see if I can do better, if I improve a lot I may come back to this shot and do it again. If I can't do better this one will stay.
Thanks for the suggestions!
