motion blur on a expression animation – possible?

[Joe Chao]

Have you tried converting expression into key frames?

[Mike Clasby]

Time>CC Force Motion Blur seems to work well on pendulums whose motion is taken from expressions.

[Thor64]

I’ll try that

[Thor64]

Hmm. That might be it but I’ll wait until I have animated it all through – then it might be the solution for blurred motion. Thanks.

I don’t get it. I think motion blur works exactly the same for expression controlled animation as it does for keyframed animation. Doesn’t it?

Yes it does. I too, like thor 64, was having problems getting motion blur (when I answered him earlier) on a pendulum (I used your pendulum setup on your AE Expression Lab Page: https://www.motionscript.com/expressions-lab-ae65/pendulum.html), and now that I go back and Check, my Composition>Composition Settings>Advanced Settings>Shutter Angle was set to a low number. I did have both the Motion Blur switches (layer and comp) on. But CC ForceMotion Blur was giving me more control, my fault, an awkward answer.

Maybe his “pendulum expression (kind of)” movement wasn’t generating enough speed to make the motion blur, or the Motion Blur switches/Sutter Angle wasn’t right.

Moral of the story, both Motion Blur Switches (layer and Comp) On, and crank the Sutter Angle up as needed will give motion blur on keyframes or expression generated movement.

Motion blur is not an exclusive thing of keyframes, it also works with expressions. AE doesn’t care how a motion is generated. I do this all the time and you must be doing something wrong. Check your comp settings, perhaps your shutter angel is simply too short.

hmm. Weird – it works now. Maybe I made a mistake when trying motion blur on expression controlled animation.
So you are right – it works on both keyframe and expression animation 🙂
