Problem rendering cinematic at set resolution

I’m getting mushy output when rendering a cinematic, have Render Movie Settings set to 1920x1080, but what’s also suspicious, the render is ignoring my Custom Camera Actor’s focal length setting, and I’m wondering if it’s then also ignoring my Focus Method, which I’ve set to Manual to have everything in focus. Note, I have Cinematic Engine Scalability checked and Cinematic Mode. Much appreciate any ideas.

try rendering in png?

Thanks, had been rendering PNG. I moved to 4K output, downres back to HD, that helped significantly. Also disabling motion blur, depending.
