Rotoscopy is an animation technique in which aniamtors trace over the live action film footage, frame-by-frame.
And here are two of my favourite videos ~
1. BREAKBOT "BABY I'M YOURS" from Jérôme Lozano (editor) on Vimeo.
It's a combination of rotoscopy and hand drawn animation. Love this style, colors and animation! Each frame selected for rotoscopy is hand painted and there are more than 2000 such frames!
2. CHERIE 25 Habillage from MATHEMATIC SAS on Vimeo.
It's done with a 3D software, and I don't understand how it is made, but it's a lovely film!
