It’s a process that works best on a layer basis
It’s often not an issue if it’s just camera motion but if a foreground object is over a static background you might have issues with the mb being cut-off yes

Looking at the example you just sent

1) You should work with 16b motion vectors pass (eg tiff 16 bpc) and a 16 bpc or floating point AE project (then also make sure there is no color management on the MV sequence). (zero motion is not properly defined at 8 bpc etc)

2) When you have multiple layers like you do, you sometimes with post-motion blur need to split in a foreground and a background pass (2 color renders) so the motion blur works as expected.

I am not sure what your animation looks like but in this case you might be able to do something with just an alpha of the foreground layer. You would apply RSMB as you have it now then overlay a second pass where you would cut out of the MV alpha the part that is not in the additional matte you rendered and motion blur just the foreground with that.

Anyway you can send us
(techsupport at revisionfx dot com)
the mv and color image?
(and project that replicates so I see your settings)

That will make it easier to debug your problem

If you rerun the installer and cut and paste the registration name and code and it does not work, send us an email with a snapshot after you pasted the name and code to techsupport at revisionfx dot com

Sorry it’s a bit convoluted as it requires two products of ours right now, but if you read the part of going from “SmoothKit Directional” to “RE:Map Displace” to convert directions or normals into motion vectors, in the following tutorial: https://revisionfx.com/tutorials/AnimExpressTut/TUTORIAL_animatedImpressionism.html

it would probably be useful to you.

Something like Twixtor PRO generates actual motion vectors to next frame but it’s usually not that useful for the sort of effect you initially describe (unless like Video Gogh here it requires to render in order to maintain an history of what happened if you like).

send me like 3 successive frames with the color and motion vectors pass to techsupport at revisionfx.com
and the AE project and I will tell you what I think when I see it
