Question Rendering video (without flickering effet, with ambiant occlusion)

When rendering settings are not very precise, lighting computation (ambiant occlusion) is not identical in each frame, this leads to flickering effects on videos.
What is the best way to solve this problem ?
Does this problem only occur when rendering with GPU renderer (Quicksliver hardware renderer) ?
One solution is to precompute the lighting (and it would drastically improve rendering speed) but this means manually texturing every objects of the scene with light textures, which is a tedious work ! Is there an easy and fast solution ?
How do professionals render videos to avoid this effect ?
Thanks a lot !

Anyone has a solution for the flickering effect ? No easy texture precomputing on 3Ds max ? Then how do pros work ?

what renderer are you using?

In a static scene you can always render to textures. That way the light is definitely static and renderspeed could even be realtime.

You can also bake final gather maps with mental ray.

Without knowing your scene and your renderer there is no answer to your question, as there are so many different techniques.

In a dynamic scene where things are moving you often have to take the path of tweaking your settings to a point where it looks good (no flickering) but doesn't take too long to render...

Are you rendering a separate AO pass, or with the scene?
