  • Rescaling Paint Effect

    Hi there,

    I’m basically doing an animation by drawing over every frame of some DV footage with the AE Paint Effect (I’m using CS3).

    I thought that I could make my composition HD resolution by simply scaling up the painted-on DV footage layer within an HD Comp. I thought that because paint was vector-based, this would work. From the pixelly results I guess I was wrong.

    Is there a quick way of displaying the paint in HD resolution? I’ve experimented with expressions on each brush (Scale: 188%) but then I’d need to alter the anchor point of each one and I’m not experienced enough to know how to do that.

    Any help much appreciated! And, no, I’m drawing all over it again!

    Simply enableing the “rasterize continous” switch does what you Need.
    No need to even scale up: the strokes are scaled up to fit the comp instead of the layer.

    Strangely though this let’s the Paint effect disregard any transformation you’d want to apply after this, no scaling, moving or rotating is possible.
    This DOES NOT make a lot of sense, but I guess with a simple precomp you can solve that.

    That tip seems on the right lines, thanks. But I’m still having some problems- firstly I can’t apply the “continuously rasterize” option to the layers that are DV footage. That’s what I painted on.

    Secondly, if I copy the paint effect onto, say, an HD-sized solid, then the brushes only take up a small section in the middle of the layer. I can apply “coninously rasterize” on this layer, but then it won’t let me enlarge it to fill the screen. If I then nest it in another comp, I can enlarge it, but I’m not sure that the “continuously rasterize” function does anything when it’s been nested…certainly it looks the same as my original.

    Is there any expression I can use to scale up the individual brush strokes and then adjust their anchor points accordingly?

    Thanks for your help
