@Joel You’re welcome.
@Benjamin Indeed! I love it too.

I use most of the times RSMB but vector motion blur is not my choice, but NOW will be
Thanks very useful!

Cool that I could provide some new informations!

I was waiting this tutorial, cool stuff, very thanks Grischa

You’re welcome!

great tip Grishcha! now we HAVE to get it for our studio!
January 21, 2010 at 2:51 am |
Thanks Brett!
Maybe I get commission from revisionfx

RSMB and particular are the must have plug-ins for AE i think. defiantly worth the purchase.
January 21, 2010 at 2:53 am |
That’s right! The whole Trapcode Suite is worth it.
January 21, 2010 at 2:10 am |
Thanks very much Grischa & John. Definitely one of those ‘A-ha!’ tutorials. Very very useful indeed.
January 21, 2010 at 2:55 am |
Cool! Probably a nice time saver!?

You’re welcome Mark.

Great tutorial. Looks awesome!

you save my millions hours of render in cinema!!!
i love you!
January 22, 2010 at 3:26 pm |
Hope you can spend them in the sun!

hey Grischa! very cool tutorial. it is really essential, so thank u and thanks to John as well for hosting it!
little question. maybe im mistaken, but i think you could just pre-comp your C4D render, and add RSMB to it [not the vector one], and youre all set. Though, that whole Multi-pass rendering, and Alpha channeling those Green boxes- why is it so necessary to do? is it a lot faster than just adding RSMB to the comp?

Hi Danny!
Thank you!
Sure, you can just add RSMB without the motion vectors but if you do that it’s guessing where the objects are going. It’s not as accurate as getting the information from your 3D package and sometimes you get artifacts. Especially in my chase where a lot of objects are overlapping each other.
And it shouldn’t take to long to render out an extra motion vector in your multi pass.
But if you don’t have a motion vector you can always try RSMB without it.

thanks John.

You’re welcome.

awesome tutorial guys I use most of the times RSMB but vector motion blur is something new for me to know , but NOW will be
Thanks

You’re welcome ahmed!
Hope you saved some render time and get more accurate motion blur!

Really great and useful information – tuts like these make you the rock stars you are. Thank you Grischa and thank you John.
Could something like XMult be used on the vector motion pass so the edges do not need to be choked back?
January 30, 2010 at 4:06 pm |
Thank you Eric!
I am not sure about XMult. Never heard of that.
If it generates the alpha and can shrink it a bit it will probably work. I guess the more accurate way is to use the existing alpha of the RGBA image.
But give it a try and report back
January 30, 2010 at 10:59 pm |
XMult is a free plug-in that does the same as Knoll Unmult, that is, unmultiplies a layer from it’s background. Good for creating mattes for flares, fire, smoke etc. Give it a try Eric, and you may also want to try the built-in “remove color matting” effect.
January 31, 2010 at 3:55 pm |
Thanks guys, I was thinking out loud when I typed that, and realized after that there would be some issues unmultiplying but thought I could compensate by adding some levels to the RGB and alpha. The result was just OK since the motion vector values were close BUT not accurate to the original.
However a second and simpler method that worked great was simply making a copy of the motion vector pass, desaturating it 100%, and clamping the the white levels so that everything was either completely white or black and using that as the matte. This method provided a 100% accurate matte for the motion vector pass with no choking needed, no black fringing, and with out effecting the RGB values of the pass. It looks great!

Excellent Eric, thanks for the tip. Best wishes, John.

Hiya! Thanks for going through this and a high five to Eric Litwin regarding his solution to the matte of the motion vector!!
One thing I’ve been thinking about though, is how would you combine Motion Blur with a Depth of Field blur.I haven’t had much chance to experiment with that, and was wondering how you’d stack the effects etc. Should you apply a motion blur to a pre-comped depth layer, before using it?
Thanks again!

Hi Anders!
To be honest: Never did it before.
I would try to apply the DOF first and on top of that the motion blur.

Thanks Grischa,
Great tutorial!
Caught your reel on Vimeo about 4 months ago. Really sweet work, super styling.
