Self-Rotoscopination

on: August 01, 2014, 05:29:54 pm
Been staring down the barrel of animation for a while now. Without blinking.

Animation.

Animation, I will defeat you. I don't want to, I need to.




Been wanting to rotoscope actual video footage for quite a while. Years even.
An old nagging desire that finally came to fruition.


After converting my dining room into a ghetto, but useful, studio I tripod recorded myself walking (NO YOU CAN'T SEE THE ORIG FOOTAGE GET OUTTA HEER).
I rushed into it and did a terrible job walking consistently so I could make a smooth loop.
I also simply walked in a straight line, rather than in an arc around the camera, so as I walk my body's angle, per the camera's viewpoint, slightly changes.
Lessons learned.



33FPS

40 frames per loop. You're seeing about 3 loops. 1/3rd of the way into the image the anim loops once, then at the 2/3rds mark it loops a second time. Notice the right arm twitch. Terrible looping.
Scarf for a little extra secondary motion. Why not.
Only bothered tracing the major edges (no, I'm not actually a baldy).

In total - this whole project took ~10 hours. Tracing the 40 frames was incredibly tedious.


I really had no clear purpose in doing this. Just wanted to.
But I learned something else by messing with the framerate. Check it out.
Contrast the above with these framerate reduced vesions:   (same timing, just different frame spacing)

15fps   50% framerate of original


8.3fps   25% framerate of original


Can you see the bad looping now?
Barely discernable in the 15fps version. Completely erased in the 8.3fps version.

Lower framerates are more forgiving.

When Disney animated Snow White and used all that super smooth rotoscoping, they had to be very careful.
One tiny glitch in the flow of movement and the whole illusion is ruined.



I'm going to kill you.
