Jittering layers wenn camera movement x axis
on Apr 28, 2010 at 8:30:12 pm

I have a made a table with polaroids on them, then i've put in a camera wich pan's to the right. Tried motion blur on and off but still the EDGES of the polaroids jitter/flicker like crazy wenn the camera moves.

the footage: http://www.loepzuiver.net/problem/jittering_camera.mov

Any one any ideas?

It's the combination of the frame rate and the pan. Sometimes the speed of horizontal motion creates a phenomenon called Judder, which looks like the motion isn't smooth.

The solutions: change with the speed of the pan, work at a higher frame rate, or render an interlaced file.

That slight up-and-down tilting of the camera during the pan doesn't bother you, huh?

Thanks Dave, will give it a go.
That up and down movement is a wiggle tot the position to give it more handheld feeling.

If the wiggle wasn't so regular, it would look more convincing. Right now the pan looks like it was done at sea.
