Question / Help Blu-ray compliant recording?

[Danfun64]

I'd like to be able to make recordings in such a way that doesn't require any reencoding whatsoever for Blu-ray disc compatibility. I understand that (ignoring SD resolutions, 4k stuff (including true progressive scan 1920x1080 with frame rates above 24), and PAL framerate stuff) my choices are 720p24000/1001 720p24, 720p60000/1001, 1080p24000/1001, 1080p24, and 1080i60000/1001. I'm confused by what I should put for video bitrate, keyframe interval (especially if I want to use one of the non whole-number frame rates), and audio bitrate. The bitrate settings don't appear to be labeled by unit. If, for example, I wanted to use the truehd audio codec, I'm not sure I can access what Wikipedia claims is the max bitrate of "18.64 Mbit/s". Secondly, I'm not sure that including "--bluray-compat" in the video encoder settings does anything in OBS Studio because the other settings take precedence, and I'm also confused by how "--fake-interlace" is handled or if I can record true interlaced 60000/1001 fps.

On a related note, I'm a little disappointed that there is no .m2ts output option that could be selected.

I, too, am totally dismayed at the steps I need to go through to make an OBS capture and burn it to Blu-ray. Perhaps I am not using OBS correctly; hopefully someone will tell both of us what we might be doing wrong. While waiting for an expert's reply, I will do some research. What we need to remember is that m2ts is a CONTAINER format, containing one or more video streams and audio streams. The container is not a simple container but does have container-specific header info. If we can figure out how to export from OBS any container that contains blu-ray compliant video and audio streams, it should be a far simpler job (i.e., no re-encoding) to wrap those streams into a m2ts container with its proper structure and header info.
