UE5 - Custom Camera format

Hi guys,
Is it possible to determine the final format of the image, from the camera, in pixels? I know I can change the image proportions tweeking the sensor values, but I´d like to choose the image size, instead…

Film back is independent from pixels. If you’re rendering out from Sequencer in Movie Render Queue, select Settings → Output → Output resolution.

Thank you for your reply, scottunreal.
But this allows me to render a movie, right?
I´d like to render a still. How to setup resolution for still?

If you’re just using the High Res Screenshot function in Unreal it will be dependent on your screen resolution and your scale control option.

And what´s the best way to make still renders?

Movie Render Queue should give the most control.

Ok, scottunreal. I´ll take a look on that.
Thanks.
