DOF flickering in animation?

[projectk]

There's two ways:


1) After effects. Render your movie as an RPF/RLA sequence, and use the depth of field filter. This is the best way if you don't want to shell out.

2) Zblur. Haven't used it myself, a plugin for cinema. Should solve your problem.

I tried rendering to RLA and there is a Z-Depth Channel included. (I didn't know this format before - thanks for pointing me). But the included Z-Depth is totally wrong. Take a look at the attached file.

Ah well, I retreated to rendering a Multipass file with Z-Depths and now it works...

I just thought that maybe there was a way to get the DOF camera effect to not flicker.

Cinema DOF in general can be hard to get flickerfree. It is possible , the main thing is not to have to abrupt outof>into focus length. But when objects overlap in Z-depth and move towards the camera, Cinema DOF is often the only way to go. It -is- possible to do it in post but the work involved doing it might not be worth it. Each object must then be rendered separate with alpha (separate, not multipass with object buffer), put in a separate layer in post and be using their own z-depth and DOF effect.
If not there will be artifacts while a sharp object is infront of a out of focus object as well as the other way around(Blurred objects infront of sharp objects).

This is at least my experience.
