For H.264 and H.265 media, what bitrate and file size is as close to original quality as possible or the same as original? (alien.top)

I recently started building a movie/show collection again on my home NAS.

I know that generally H.265 files can be 25-50% less bitrate than H.264 and be the same or better quality. But what's the golden zone for both types? 10 Mbps for a 1080p H.264 movie? And would it be like 5 Mbps for H.265 1080p to be on par with H.264? What about 4K?

For file size: would it be 25GB for a 2 hour 1080p movie to be near or at original Blu-Ray/digital quality?

I was wondering the same thing recently because my nvidia captures videos took like 1 TB of space on my main PC. I wanted to compress them by switching to H265. In FFMPEG there's no simple option like "loseless compression", you always have to enter manually the bitrate or quality. Rendering a bunch of videos with different bitrates and trying to compare them to see if there's a significant differene is a really long and annoying process. I gave up and just burnt everything to bluray instead.

loseless compression doesn't exist for video. Like mathematically impossible.
