This is one of those questions I feel like I should know the answer to, but anyway.
How heavy is Pixel Spread, processor wise? I’m trying to speed up this comp a bit and it already has too much Dof and defocus going on and I’m about to turn on the motion blur. Someone told me years ago Pixel Spread was a proc hog but I wanted to get a quick second opinion.
Compared to DoF, the Pixelspread is def. peanuts to the processingspeed. So there should also a way improving the time with another defocus node/workflow, even if all types kinda need some heavy ressources.
As an aside, I can’t remember the exact name, but there is a SFX Pixel Spread (matchbox) that you can use in Action (or Batch I guess), that uses a Strength input – so the effect of the Pixel Spread will be wider or narrower based on the alpha or gmask input.
