Jittery "Brush Strokes" Effect
on Jan 20, 2011 at 11:17:46 pm

Hi All,

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.

Thanks for your help.

I'm pretty sure that's just how Brush Strokes works. It's been a long time since I've used it, but I don't recall any time or frame-related controls in it. I'm not at my AE machine to check.

Do you know of any other filters that I can use to make my footage look like a moving painting?

You could also try playing with the settings in the Cartoon effect.

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?

Thanks!

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.

Perfect! That's going to work fantastically.

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.

Hi!

The Posterize Time effect work only with non-vector layers. I try to do this trick with vector graphics and the precomposed layer doesn't move at, even when I change its position or scale. When I turn off continously rasterize mode, it works, but the vector quality is missing. Any other idea?

Hi Albert,

If you are using a vector layer, just apply the brush stroke and posterize time effects directly to the vector layer. If you need to precomp it, it should be fine as long as the effects are not applied to an adjustment layer. When you turn on continuously rasterize on a precomp with an adjustment layer, it applies that adjustment layer to the current composition.

Hi Alex,

I applied the Posterize Time effect directly on my vector layer. But when I set it to 0 frames, it freezes and I cannot change its position, scale, nothing, which of course make sense, but this is not what I want to achieve. When I disable Cont. Rasterize on that layer, it works fine. But of course I need it for the quality, so this is not an option. Try it yourself, here's my vector file:

Thanks for sending a file. I'll post some screenshots here to try and figure out what's going on. When I put the brush stroke, then the posterize time effect on your vector.swf triangle, and on an illustrator file, I get no issues with the scaling and positioning freezing, with rasterization on and off. I do notice it freezes if you have the effects on an adjustment layer above the vector file, then precomp and try to adjust it in the main comp with continuous rasterization on. I may not be understanding though what you are trying to do, so hopefully the screenshots can clear things up. Let me know if this is what you are trying to achieve.

Thanks for the screens, I should be more precise. I can move the object, sure. But when I try to ANIMATE the position or scale, then it won't move.

P.S. Here's my thread about my issues: https://forums.creativecow.net/thread/2/1122251

Precompose and it'll work.
