Cartoon filter

Hi!

Don't know if this is the right forum, but I just got a thought that sounded good in my brain, so...

When encoding cartoons, you'll often find that the compress less that real movies, due to high contrast scenes and large areas with the same vivid color all over. So what I came to think of, it would have been nice to get rid of the least visible gradients. Think of still images in photoshop, if you have a picture (preferrably a cartoon picture or something) with a low number of colors, but blured, resulting in all 16mill colors somewhere. If you ran a 'Posterize' (reduce number of colors), it would compress much better.

Is this possible when encoding video? And does it exist a filter for it?

Just a thought
