h.265 - Raspberry PI 4 (settings, levels, profile, compatibility)

Hi,
for the previous raspberries has been given a certain h.264 profile to ensure compatibility for smooth playback up to 1080p (high profile @level 4.1), irrespective from quality or compression settings. Over the years this has been the perfect way to build files for R PI.
Nowadays the R PI 4 supports hardware decoding for h.265 up to 2160p. Is there a respective kind of leveling or profiling for h.265 encoding in handbrake?

Well, surely the RPi developers would know what the built-in ASIC can decode? I couldn't find it quickly on the website, so you'll have to ask somewhere, I guess maybe they have a forum of their own.

A quick googling leads to
this document which says:
The H.265 / HEVC decoder is a HEVCv2 Main 4:4:4 10 design supporting bitstreams up to profile 5.1. Maximum picture size is 4096 x 4096.
So Main 10 profile up to level 5.1.

But if I'd ask in their forum for proper settings in handbrake, where do you think would they delegate me?

Nope, a quick googling leads to several hundreds url's with thousand fragmented informations. That's why a forum is build for and why people use it. For questions and discussions
But thank you for the meaningful part of your answer.

6th hit with very reasonable keywords, no need to look at hundreds or thousands.
