adding motion blur to a matte

[Anonymous]

Hi-

I have been painting/rotoing several mattes for some composites. I have the mattes finished but I need to add motion blur to some of the edges. When the objects start to move faster they look choppy. The mattes have a slight blur on all the edges but not enough to add motion blur. I am working in smoke 653 and the footage is HDCAM. Any suggestions would be helpful.

thanks
matt

r u comping in the timeline or in dve? if you are in dve, have you tried just turning on motion blur in the setup?

I believe that motion blur in the DVE only affects movement of that layer… not the movement inside the layer.

Your besy bet is probably a spark of some kind. Motion Blur.

If not… you can try a slight average or MIX volaue off the timeline, but I think that will just look messy.

sorry, i thought u were actually moving the layers –> not using animated mattes

really, w/o flame’s batch—> u really gotta try smoke’s batch (timeline) 🙂 hehe

try a mblur spark

Inferno/flame has the possibility to apply motion blur to g-masks. I don’t know if smoke has it? If it hasn’t or you painted the mattes by hand and you want to add more blur, you can try the plug-in reelsmart motion blur from revisionfx.
(Shake and commotion has motion blur on spline masks, that won’t help you now, just thought I’d mention it.) Cheers.

I usually render the matte out of DVE (by turning the front layers off) and the reload the renderd matte back into DVE as a single layer. If you do this and then turn on the the motion blur it works.

Good luck

looks like a pretty old thread 😉

anyways, still valid – until smoke2007 where you have a motion blur for gmasks.

in previous versions you can define the mask on one layer (static position).
reenter it to the matte of the target layer
animate it on its “original” layer & it will be motion blurred

To add motion blur to a matte in a smoke, you can process the matte, and then apply the speedsix moblur, and then apply it in the DVE.

There´s no other way to do it.
