This gives an image a flickery 'line boil' effect

[CyberFilth]

So I just tried something tonight that worked out better than expected, and I wondered if I'm reinventing the wheel a little.

I loaded a background image that I drew into Moho, but it looked a little flat. I wanted it to have something like line boil happening, but not to a distracting degree. So as well as the background image, I also imported an image of just the line art, with a transparent background, and used the Trace Image option to convert it to a vector.
By reducing the opacity of the vector outline, it works quite well as shading for the image underneath. Plus, I can add a little animated vector noise so that it has a little visual interest.

This is the original image


This is the outline that was converted to a vector


And this is the end result, the flickering might be a bit too subtle on YouTube though

Now that's a nifty trick! And I think you can build on that, because, as you stated yourself, it's a bit too subtle for Youtube. (That's the one thing I hate all video formats for: they can't really deal with all the grain and texture and drawing magic you can create with analogue film. And remember that every streaming service, like YT, may strip your carefully adjusted noise from your video and add its own in playback!)

So since you have the lines as a vector layer now, you could experiment further: you could assign any brush to the outline, adjust its width, and you could use vector noise on the outlines as well.

I already like the overall effect, the colouring looks nicely handmade and organic.

Great idea and nice outline like this! I had to look twice to see it moving in the video (thought for a minute you converted a still to a video), but that's probably easy to magnify. Thanks for sharing!
