When I apply the "brush strokes" effect in After Effects CS5 (via effect>stylize>brush strokes), I get an effect that looks great when the video isn't playing (and I can adjust brush stroke width, density, etc. just fine), but when I generate a RAM preview, the effect looks all jittery and every stroke is wiggling around in constant motion. How can I get a more subtle painted canvas look? Nothing looks pixelated, the effect is just in constant motion. Are there controls for the effect that I'm missing.

I'm loving the cartoon effect, but I have a question about it. I want my character in the shot to look like he's stepping out a painting. I used the roto brush to isolate him from the background, and he's got the cartoon effect on right now. But I want the cartoon effect on him to fade away until he becomes a "real person" again. Alot of the effects have the "blend with original" option which makes something like this easy, but the cartoon effect doesn't seem to have that. Any suggestions?

Duplicate your man layer and remove the cartoon effect from one. Then use whatever method you desire to bring in the non-cartoon version. You could use a precomp to drive a Gradient Wipe transition, you could animate the opacity, you could use a mask...endless possibilities.

I know this is an old thread, but it still pops up in top results on google, so just thought I'd post my fix for freezing the brush stroke effect in place for any future readers. You can put the Posterize Time effect below the Brush strokes one on a layer and set it to zero to freeze it. Or if you have video and don't want it to freeze as well, put the brush and posterize effect on an adjustment layer above your footage, and precomp if you don't want it affecting anything else.
