Rendering animation with ray tracing

I am trying to render out an animation of a scene that uses ray tracing for global illumination, reflections and translucency. Can I tell the sequencer to render each frame as long as it takes to improve the visual quality?

I have seen this in demo videos of ArchViz. They are saying each frame took x minutes to render. How do I achieve this?

Thanks for any help.

with RTX unreal renders out fairly quickly
there’s settings in the sequencer render menu that allow you to slow down the render.

unless you’re using path tracing it won’t take longer to increase the quality.
you just increase the sample settings in either the lights or the post process volume along with reflection bounce and whatnot
there’s info here for what raytracing can and can’t do
