frame blending time remapped pre-comps

[Kevin Camp]

if your pre-comps contain footage, then enable frame blending for those footage layers in the precomps. when you render with frame blending (or enable it for preview renders) that footage will then be frame blended.

for other, non-footage elements, ae’s native motion blur usually works. when enabled, it should ramp up the blur amount with the time remap.

[Tom Masters] “I have a pre-comp with CG renders, and want to globally re-time that comp, but I do not have the options of frame blending (or interpolation)”

Just to add to Dave and Kevin’s excellent advice, you could also use AE’s Timewarp effect, or RE:Vision Effects’s Twixtor. Both use motion estimation to retime comps, and both offer far more flexibility and control than simply turning on frame blending. If you have or can render a motion vector pass from your 3D app, you can use it with Twixtor Pro for better retiming.

Closely related to this topic is motion blur; RE:Vision has another tool called ReelSmart Motion Blur which uses motion estimation to add (or reduce) motion blur. I’ve been using RSMB Pro Vectors, in conjunction with a motion vector pass from my 3D render, to add motion blur post-render.

worked great, thanks!

Dave: didn’t I say I was rendering CG passes? That is FOOTAGE, which makes total sense to re-time.
And apparently from Kevin’s reply, it is very possible. I tested it, works great.

(If ya don’t know, it might be best not to answer. Just sayin’)

very helpful, thx.
I just find the standard time re-mapping very intuitive, and now with motion estimation built in (as of CS3 I think) it is super handy.
