    Hi,

    I’m doing a frame by frame animation and have used the paint brush tool to draw onto my footage. The footage I used as reference to paint on top of was quite small so I scaled up the footage. The only problem is now the paint brush strokes are all pixelated, I’m guessing because of the scale up. What I don’t understand is why its pixelating if the paint brush tool is meant to be vector. Does anyone know how I can make my animation not look pixelated? I’ve attached screenshots below.

    Thank you. By nested do you mean precomp? I just precomped my scaled up footage and tried to copy my paint strokes frames onto my precomp but they don’t show up. Is this what you mean? I’ve done days and days of work so would like to find a solution where I don’t have to redraw everything again.

    Thank you, just tried the Detail Preserving Upscale effect. I think it’s going to work. It’s not perfect but seeing as the style of the animation is hand drawn with wobbly lines the pixelations have sort of turned into wobbles which I think I can get away with. I’m also going to apply all these other effects on it.

    Thanks so much! I’ll know for next time how to do it using the method you outlined.

    While what the paint tool draws is pixels, the path it follow while it paints is a vector based curve. You can’t access this path directly like you can a mask, but you can copy the paths from each paint stroke and paste it into a layer with a mask or a shape (pasting on top of a dummy mask is required sometimes) and then scale that layer. The simplest solution is then to stroke those enlarges paths and they will be clean. However, if you have some “english” on the strokes you painted originally that’s not going to come through.

    What I’m wondering is if you could link the path from your original paint on the small layer to a paint effect on a large layer, and then scale (and link) the path with expressions. If you head over to the expression forum Dan Ebberts and boys might have an answer for you, to save you doing it all again.
