Radial Motion Blur Without Translation Blur?

[user_deleted]

Hi I am blurring an object spinning in the air. It is also moving all over as it is spinning. When I use move 2D or Rotate, keyframing the center values to be the center of the object, I get a blur which is a combination of the translation and the rotation and I only want the rotation blur to be seen and not the translation blur. Is there any way to do this is Shake?

Thanks
Pete

i'd start with:

CODE
Color1 = Color(720, 576, 1, 0, red, red, 1, 0);
ColorWheel1 = ColorWheel(250, 250, 1, 0, 1, 1, 1);
Rotate_SPIN_W_MBLUR = Rotate(ColorWheel1, Hermite(0,[0,99.71,99.71]@1,[1960,99.71,99.71]@10),
    1, width/2, height/2, 1, 0.5, 0);
Brightness__BREAK_C = Brightness(Rotate_SPIN_W_MBLUR, 1);
Move2D_WO_MB = Move2D(Brightness__BREAK_C, Hermite(0,[460,-98.75,-98.75]@1,[1,-98.75,-98.75]@10),
    Hermite(0,[317,-98.27,-98.27]@1,[-14,-98.27,-98.27]@10),
    Hermite(0,[0,0,0]@1), 1, Hermite(0,[1,0,0]@1), Hermite(0,[1,0,0]@1),
    0, 0, Hermite(0,[150,0,0]@1), Hermite(0,[150,0,0]@1), "default",
    xFilter, "trsx", 0, 0, 0.5, 0, 0, time);
Over1 = Over(Move2D_WO_MB, Color1, 1, 0, 0);

it the object is already movig around, you could stabilize it, then add the rotation blur, and matchmove it back to the original position.

there are probably more elegant ways to do this

If I understand you correctly and you are speaking about controlling the motion blur, then I would approach it by turning off motion blur in the actual transform node that is moving your layer. I would then add a new move2d node and link only the rotation curve to the rotation in the move2d. Then, turn inverse transform on, so that there is no move applied on the new move2d node. Turn on motion blur and adjust the shutter to your liking.

Hi thanks for your help I guess I'll stabilize it first then before adding the angle keyframe. I was hoping there was a way to do it without 6 nodes.
Thanks again

You could turn off motion blur in the node with the translation - copy the node and just do the rotation, but turn useRefernce ON... it won't rotate, it will just apply the motion blur for it. Very handy.

[user_deleted]

yes, you are correct. I mean't to say useReference instead of inverse transform in my email. My mistake.

Hi,

I just saw ur query

Its very simple, After tracking the object, ( u can use move 3D to track in all 3 directions manually/if its 2d rotation use Move2D only and "always usereference option on") then take the move 3d/2d, open the pan parameters delete it ( thats use only rotation parameters ) and make sure usereference is on......

Otherwise try buying the License for RSMB plugin ( real smart Motion Blur )

http://www.revisionfx.com/generalfaqsMVMaya.htm

if you give your input it will automatically calculate the pixel miovements and give the MB. you can also control the sensitivity and amount of MB.

im really enjoying the plugin

any doubts let me know
