Directional Blur Based on tracking Data

[jfotter]

Does anyone know the math behind what it would take to take a directional blur and drive it based on tracking data. This is a simple trick in the flame when you reverse parent an image to an axis, and Tinder’s d_blur plugin does this exactly. Anyone have any ideas on how to re-create this manually in After Effects or Shake.

In Shake you can fool a Move2D into doing it:

o Track your stuff with a Tracker or Stabilize or whatever and leave that node floating around but not in the tree
o Grab a Move2D and link it to the track with expressions on xPan and yPan of Tracker1.track1X and Tracker1.track1Y respectively
o Turn useReference on at the bottom
o Turn motionBlur up to 1 and fiddle with the shutter controls to taste

I really wish you could do this with a Stabilize node – all the buttons are there but sadly they don’t have the same effect. Setting the reference frame to “time” there results in no movement or motion blur at all…

for getting any kind of mblur…what i usually do in shake is that lets say i track the shot in mokey in shake…in the stabalize node u will find the mblur settings…so just make it to 1…u will get a mblur…only thing u have to play with the offset setting to get the right blur…..

Yes but I want to add the motion blur to the layer without “moving” it. The previous post is exactly what I needed. I did not know about the reference frame toggle. Thanks
