CC Motion Blur sample problem in AE CS6

Recently, I have been having a problem with the CC Motion Blur effect. I have a rendered 3D animation and want to apply motion blur which is as far as I know not possible with the native After Effects motion blur but with the plugin/effect CC Motion Blur.

So I added the effect to the video layer but instead of a motion blur this creates just two frames of the video blended together. It seems like the motion blur samples are dropped to 2, even though it is set to 16.

The weirdest thing is that when I animate a test rectangle on top of the video in that same composition this rectangle then has motion blur but the video remains its way.

Correct answer Rick Gerard

Your problem was nothing more than a render order issue with Time Remapping. If you ever have problems with CC motion blur just remove the effect, pre-compose the layer moving all attributes, then apply CC Force motion blur to the nested comp.

I just realized the reason why the video was so stuttrey: I had the fps of the comp set to 15. So, i set it to a higher value again. This makes the motion blur obsolete, even though it still does not work.

Anyway, thank you Mr.Gerard for helping!

Maybe the effect can somehow (little contrast?, similar colors?) not track the pixels and is unable to create the desired effect.

Yours Sincerely,

I did exactly that and also tried the effect without the Time Remapping directly on the video (picture series) but I alway had the same result...

Or maybe I overlooked something..

Pre-compose the time remapped layer and don't use an adjustment layer. CC force motion blur is looking at the layer before time remapping is applied. This is a typical procedural error related to using time remapping that is not limited to CC Force Motion Blur on an adjustment layer.

This does not work, either. I also tried putting the whole comp in an new comp and applying the Force MB there but this also does not work.

I also tried different frame blending modes but none of them solves anything.

P.S.: Without the Force MB the frames do not get blended, both with frame blending turned on and off.

We need a screenshot with the modified properties of the layer giving you problems revealed and comp and workflow details to help. I know of no bug so it's either user error or some weird combination of effects that is causing the problem.

A very quick fix would be to pre-compose the layer that is giving you problems making sure you move all attributes to the new comp, then apply CC Force Motion Blur to the pre-comp (nested comp). This will assure you that the effect has actual pixels in motion to work with.

Thank you for the reply!

This is th screenshot.

I tried to pre-compose the video (multiple pictures) and applying the effect on this pre-comp and later on another adjustment layer, but that does not fix the issue.

Further, when I add a shape and animate it this shape gets the motion blur without problems

I have no other effects other than CC Motion Blur on the Adjustment layer and Time Remap on the video (multiple pictures) layer applied.
