motion blur problems

[Steve Roberts]

Is motion blur switched on for both the layer and the comp?

[Miha Zaletel]

yes I got everything enabled(on layers an in comp), the problem is that it woks with animated square in different composition, but in the light drawing comp is no motion blur and I recreated this for three times(3different comps).

Hey Dave,

I have a huge and elaborate AE project with a lot of spinning cylinders (CC Cylinder). I have a horrible problem with the side spinning graphics being jumpy. I just learned about motion blur in AE, I have tried to apply it with a variety of tests and can’t seem to get anything to happen.

Do you think it is because AE doesn’t recognize the CC Cylinder motion as true motion? It is a keyframed move… seems like AE motion blur would read this properly.

If I use CC Force Motion Blur, do I place it at the bottom of the stack of effects or will it work on top? (I am asking because you are right, just placing the force motion blur on the layer causes AE to come to a crawl.)

Thanks, Matt

Thanks for the great reply Dave.

here is one for you….I just moved the CC force blur to the bottom of the stack of effects on my layer and it negates the CC Cylinder effect. Suddenly my nice cylinder is flat….
Switching off the FB effect brings back my cylinder.

Rats… I need something to be easy right now.

OMG…. okay, CC Cylinder is the problem. When I pre-comp the cylinder layer it goes flat, loses the cylinder.

Yikes…. I feel totally stuck right now. I am experimenting with manually keyframing a directional blur for every spin of the cylinder.

I’ve had this issue on a few projects that I did for American Airlines. The simplest work around (if not already discussed and I realize that this is a late response) is to render the file as an uncompressed file (animation compressor) then import the flattened file to add motion blur using CC Force Motion Blur. That way the renderer will not have to deal with the complexities of all the effects at one time. We had a similar situation with Adobe Premiere when captured video footage (with all kinds of effects) had to be compressed to an MPEG-2 format for DVD. The compression with all of the effects on the layers also being compressed was going to take nearly 3 hours for 5 minutes of footage. The work around for this was to render the effects and export the file in its native DV format then import the flattened file for MPEG-2 compression. This cut the entire time down to only 45 minutes. Hope this helps someone in the future.
