    just remember, it will never smooth the outer edges of objects, only AA can do that,
    so you definitely need some amount of AA...

    yeah I'm sure they have their limitations (NeatVideo seems to introduce very slight artefacts in some cases) so I plan to do a lot more testing as to when these would be big time savers in the sorts of things I plan to use them in. It's the dreaded foliage pixel fizz, that no amount of time reasonable AA / AS / OS settings (rendering at x4 seems out of the question for now) that I'm looking to battle with. So far tho results seem extremely promising

    There are some post cheats that dont replace proper AA and moblur. But a sobel filter can make a quick luminosity mask that allows isolation of edges to apply post-blurring. This examples is zoomed 300%

    This moblur cheat only works on the outside of an object with an alpha, but it recently saved me a huge amount of render time for several elements that were moving rapidly thru frame and I needed to render out fast.

    I rendered a quick 12-pass version. Then it was easy to make a mask in comp that excluded the white and black parts of the alpha, allowing me to post-blur only the steppy moblur area. This took about 4 seconds per frame in comp as opposed to several more minutes per frame in 3D. The bronze colored part is the CG object, comped over a BG plate-

    interestingly, you could combine it with this technique...
