Ah - well - I think it's the voodoo part that I'm most curious about. I have no idea how shake works, but maybe they have some sort of plugin like ReelSmartMotionblur where you can feed the directional data into the plugin so it will fake motion blur? On the other hand if you rotate something in Fusion you can connect all kinds of other parameters to the animated angle, so that's a way of transferring rotation information. But I guess that's not what you mean is it?

Hey Shadow,

No its not a plugin or a MoBlur node. They mention RSMB as a better way to do this trick, but this trick costs no additional $. Here is some text from the tutorial: The trick is to use a Move3D node to match the movement of a temporary element (such as the letter "X") to the movement of the fan. Then, the temporary element (node) is deleted, and the Move3D is applied to the moving element. Since this normally moves the element, enable the useReference parameter in the Move3D node, and activate the motion blur. Because useReference is active, it only applies the motion blur without actually moving the element.

hi david,

use a transform to match the motion; copy this transform and paste a copy after itself, check InvertTransform and FlattenTransform in the first transform and MotionBlur in the second transform.
its an old trick shake has just simplified it.

Are you sure you don't work for Eyeon?

Perfect tip, does exactly what the Shake trick does. I whiped up a quick comp and it does as advertised. Thanks for this one. You should post this technique in the VFXPedia.

I have updated the code I suggested Daniel use as a prototype for a forums Bot:

Thats a really bad assumption. You don't always want to do both at the same time. Sometimes you need to mdiv only. But You can't.

i totally agree
almost all color tools have a pre-devide/post-multiply check box ,thats not true for shake
and i have never felt a need for a seperate mmult or mdiv in fusion

shake is an excellent tool to work with and its got its own work flow and so is fusion and its workflow lets adapt to fusions workflow and not force shakes workflow in fusion especially when its not needed.

thats why we have Bol , CT and other tools.

i thought i wrote that in english.
thats a comment i made out of my understanding of fusion; --about a year back--
its NOT an assumption.

"use a transform to match the motion; copy this transform and paste a copy after itself, check InvertTransform and FlattenTransform in the first transform and MotionBlur in the second transform.

This tip works perfectly, unless the image leaves the frame, then because of the flatten transform, it clips everything outside of frame. Can you think of a way to simply reference the motion blur setting from another Xf tool?

Many thanks in advance...

Hi, Xoo!

Setting the first XF to "wrap" should do the trick...;-)

Actually looks like both Xf's need to have wrap selected. But that's exactly right! Thanks man!

edit:

Hehe, looks like I spoke too soon... After implementing this today, I ran into further limitations for this technique. If your element spans across the frame it wraps incorrectly. Also, on more extreme translations, the wrapping screws up, clipping part of the edges off and wrapping them on the other sides. It works great under the right set of circumstances, but not always, and not quite for what I'm trying to do.

edit 2: The incorrect wrapping issue can be gotten around by 'uncropping' the plate, multiplying the transformation by the same factor, and recropping to the original frame size. Big thanks to AK for that!

hi

I've been more than busy lately to be able to frequent this forum, i did manage to make some time to update/improvise/optimize/cleanup(or whatever ) the macros(some of them) i'd pulled off from the post earlier.

these macros could teach you guys some nice techniques on cleaningup macros in general. they are 1up in terms of interface (in relative terms though ) with some useful and some confused expressions. i say confused because i feel they can be optimized. tabbed/grouped controls, proper mask inputs, less number of tools etc.

i use some of them more often, the others are for my friends here.

 Shaily_ShakeToFusion_Macros_5.2.exe.txt   116.44K   24 downloads

remove ".txt" from the filename and doubleclick, itll automatically copy the macros to your eyeon\fusion(5.x)\macros folder. no need to restart fusion
the contents are exactly the same, they are only split for convenience.ill upload these macros on vfxpedia with proper description soon(er or later ).

cheers
