Filtering Basics in Action, covering Linear, Anisotropic, and Elliptical Weighted Average (EWA) Filtering algorithms in Action. tldr: Linear: when there is no animation, integer-based animation only Anisotropic: when there are heavily rotated surfaces in your scene EWA: when you there is scaling…

“I see juniors and even some mids get wrong.” Haha. It’s cool man, we ALL get this wrong. I’ll start using anisotropic now; I always thought that EWA was the goto for heavy x/y rotation. Thank you for the video.

Its this kinda stuff that made me wish stuff was labeled for what it should be used for, not for what it was. :slight_smile:

There’s that old-by-now FXPHD you did going over this that I think ultimately made me too lazy to memorize the proper use of them instinctually. I’d always have to Refer Back To My Notes. Thanks for the refresher! :slight_smile:

Jambo! On the 1st of Tha Month no less!!!

“I see juniors and even some midgets wrong.” Haha. Been working too long I guess…

Hey @randy how do these relate to the filtering options we have in the Timeline resize node? I was always curious why we have one set of filtering option there and a completely different set in action. thanks for the video, good stuff.

That’s a good question @TimC . I suspect that the timeline resizes are different than the Action ones because Action is a 3D environment and has to take textured polygons into consideration, whereas, the Timeline doesn’t. Or does it? On the surface they do do similar things, but, under the hood th…

…or that filtering would change based on the transformation matrix per-automatique to always give the best result (as an option).

The ones like Lanczos and Gaussian?

I often use this system to cleanup: stabilize in action sequential paint negate the stabilize comp this cleanup back over the plate But the grain/image goes soft. I’ve got the action surface rendering with EWA on both ends, so what am I missing? Thanks!
