Is there any way to use Constrain Aspect Ratio and Aspect Ratio Axis Constraint at the same time?

I have no direct experience with this personally, but according to google, you can:

Yes, you can useConstrain Aspect Ratio andAspect Ratio Axis Constraint simultaneously. To do this without conflict, you must enable Override Aspect Ratio Axis Constraint in your camera’s details, which allows you to explicitly lock the framing behavior (Maintain X-Axis or Y-Axis FOV) while the aspect ratio is constrained. [1]

How to set them up together

  1. Select your Camera (Cine Camera Actor or standard Camera Component).
  2. Navigate to the Details panel.
  3. Under Camera Options, check Constrain Aspect Ratio.
  4. Enable Override Aspect Ratio Axis Constraint.
  5. Set Aspect Ratio Axis Constraint to Maintain X-Axis FOV or Maintain Y-Axis FOV, depending on whether you want to preserve horizontal or vertical framing as the screen size changes.
  6. (Optional) Adjust your Crop Settings to the specific aspect ratio you need for your final framing or cinematic render. [1, 2, 3]

This setup is highly recommended if you are rendering in the Movie Render Queue and need your viewport preview to perfectly match your final output resolution. [1]

Just thought I’d at least help point you in a direction.
