Archviz Camera Motion is Not Smooth, Not Sure Why - UE5

I’m new to UE5 and using an office scene from the marketplace to create a simulated walking path from the foyer to a desk. When exporting the final render it’s not as smooth as I’d hoped, especially when the cam is rotating. I did a quick version and then a slow version (thinking that the speed of the cam movement was creating the problem). The slow version is better but still not ideal - seems jagged when the cam is turning. Am I missing an obvious setting that would help this problem?

Attached are the two clips I’ve exported (quick and slow).

As some background:

  • Instead of a camera rig rail I just used a CineCamera Actor and then changed the location and rotation of the camera by “Transform” keyframes (Cubic Auto). Would a camera rig rail setup solve this problem?
  • I’ve tried a variety of Anti-Aliasing and Console Variables in the Render Settings but the results have been similar
    *I am rendering on a Mac (3.8 Ghz 8-Core Intel i7, 32GB Ram, AMD Radeon Pro 5500 XT 8GB video card). Would the final result be any different (or better) if I did it from a PC?

Thanks in advance for any input / tips. As I’m a newbie I hope that this is just something simple I’m missing in terms of a setting or using the wrong workflow.

You have too many keys so your motion isn’t particularly smooth. See if you can just have a few getting the move you want. And then make sure to crank up motion blur

Ok, thanks so much. When you say crank up the motion blur, I was adjusting motion blur in the console variables along with anti-aliasing as per the attached snaps. It would be faster to preview the effect using the “Motion Blur” settings on the CineCameraActor but I’m not sure how the CV settings (MotionBlurQuality, MotionBlurSeperabel) correspond to the Camera settings (Amount, Max, Per Object Size), or maybe these cam settings should be adjusted in addition to the CV ones.

Your settings look reasonable. You could bump temporal simply higher to 64 for a short test.
Also, make sure you don’t have keys next to each other. Easy to do in sequencer.
