I found a strange problem.
In a viewport and when I am rendering that sequence of files in Mantra, camera movement is smooth and everything is fine.
But when I tried to render same sequences in Octane final animation is shaking. Why is it happen and how to solve this problem?

The camera is shaking in this scene due to floating precision problems. Your camera is too far from the center of the scene, and the focal length is too long. Octane works using single precision floating maths, that can't manage such large numbers with enough precision.

Why do you have this kind of camera setup? If you need an orthographic projection you can set the camera projection to orthographic, to place the camera closer to the objects and avoid this problem.

I have same issue in Blender plugin. OpenGl preview and Cycles render is smooth while Octane render is not. I'm using real world scale values with above 40km big objects.
