Geometry is moving strangely with motion blur on.

Hi!

I have a camera tracked plate and have added some 3D elements with Cinema and Octane. The track is solid and I can render out fine without motion blur but as soon as I turn motion blur on the render of the geometry seems to wobble about a little bit as if it's not correctly synced with the camera movement. Footage is 25fps with a shutter speed of 1/50 sec and I have set the "shutter [sec]" to 1/50. I have also changed the "time sampling per frame" in settings to a high number (25).

Any thoughts on what might be the cause?

Thanks!

Kraig.

It's a bit difficult to say without at least a screenshot, anyway, probably, if your track is moving quite fast, you need to adjust the Time sampling per frames value in the Render settings:
