Kronos's MotionBlur vs. Reelsmart Motion Blur

Hello all,

I am doing a lot of 3D these days and want to get a motion blur plug-in for After Effects. I recently had to seriously re-time a shot and so downloaded the trial of Kronos and freakin' love it! I was happily typing away to my boss that we should buy it, but realized that I should probably do some more research.

I have been surfing the web for a little now and can find plenty of comparisons between Kronos and Twixtor, but none between MotionBlur (which is the motion blurring plug-in that comes with Kronos) and Reelsmart Motion Blur.

I almost blindly trust The Foundry due to past experiences with their products and so tend to think that they are the right choice, but thought that I would ask around first.

Thanks,

- Spencer

kronos can add motion blur to a layer based on the movement in another layer. It's a different method to render out from 3D apps, but the end result is the same.

but reelsmart motion blur can actually remove blur in -2 mode if you accidently shot with a slow shutter. it's faster too.

Did that help muddle the decision? :)

How does that work? I thought that feature was about looking at one layer for motion estimation and then applying the effect to another.

RSMB (which is the one I chose) can simply use a motion vector pass straight from my 3D app, avoiding any motion estimation to try to deduce the vectors (and therefore avoiding blobbing or the need for tweaks).

I'm not a Kronos user, so please let me know if I've misunderstood something.

Kronos uses layers for planar vectors. You add kronos/timewarp to a alpha moving layer(a precomped white solid from a 3D program) that is representive of the movement of the individual object. You add timewarp to the alpha layer and change warp layer to your final colored/textured model. It's kinda funky, but hey, what isn't?

use the matte layer with inverted alpha to remove artifacting and isolate multiple passes. plus use vectors 100%, smoothing 28. filter extreme. you can try RSMB as a trial and see if you like it better. nothings perfect, after all:)

I've used RSMB Pro with motion vectors from C4D on my last couple projects, and I've been really happy with the results. Veering a little off-topic, Twixtor Pro can also import motion vectors for smoother time-remapping.
