Is there a pixel filter that will conserve energy during anti-aliasing?

I'm running a post bloom filter on some objects that are close to pixel sized and the bloom effect is flickering because the average brightness changes as the object moves across the screen, due to aliasing.

Cheers,

Just render it with sub-pixels, bloom it, then bin it.

Sure, that would work, but then my 10000 frame long render goes from 8K to 16K… the disk space horrors…

I'm not even sure if that's technically possible. Reconstruction filter does exact opposite thing, fights aliasing by introducing bias in signal estimation.

You could apply Geometry Filter Width render property to disallow points being smaller than a pixel (or more on a crazy side, post-process an image with temporal analyse and stabilize brightness for a given region).

You mean you render with only 2x2 pixel filter?

Ha, yes, actually for most renders I've found the Gaussian 2x2 filter to be perfectly fine.

Sorry, I meant pixel samples 2x2 as 8K->16K indicates…

Ah whoops, yes, I conflated the two for a second…

pixel samples are 9x9… so… 72kx72k then.
