Using velocity pass to motion blur in after effects

[SmurfN]

Hi, i cant get the velocity pass to create correct mblur in after effects. im not sure if its because i use wrong settings or its just broken (probably the former).

it seems to just create weird blurring around edges no matter what property i use in "CC Vector blur" filter. (strength cranked up to more clearly see what the blur does.)
Here the person in front should be very much blurred in motion.

Ive tried with velocity offset 0,0 and 0,5.

CC Vector blur doesn't do this kind of thing, it does not look for or use actual vector data despite what the name suggests (see http://forums.cgsociety.org/archive/index.php?t-742069.html). What you need is a plugin such as Reelsoft Motion Blur, or you can use other software such as the free Fusion to create this effect - you can see that in our video about Motion Vector pass (and Fusion was chosen since it is free, and since After Effects doesn't support this effect natively without paid plugins)

 

Hope this helps!
