    Hello
    I created a video ,that a Man is running on Playground , and suddenly he hit by a stone and fall into the floor .
    The problem is that , when Man hits the floor , he lay into the Red Color Badsheet ,not into the sand , because he did not wanted to lay on the Ground and get dirty .
    The Problem is that my camera is moving alot , if i use Masking , i think i need to create couple of masks , and i need to rotate them alot .
    Is there any other way to do this .

    Regards,
    Taha .

    That is normal. Rotoscoping is complex, tedious work.

    Just for comparison, I recently had to rotoscope to separate a man’s upper body from a background, and I had to use eight masks to to it, each animated frame by frame. And that was a simple shot, since his lower body was blocked by a desk.

    There are many ways to separate a foreground subject from a background. The most common ways are listed here:
    “Compositing overview and resources”
    The ones that aren’t a lot of work (such as color keying) take a lot of planning and discipline during shooting.
