Oh by the way:

https://downloadcenter.samsung.com/c...G_220216.0.pdf

Page 153
HEVC (H.265 - Main, Main10), max 4096x2160, fps 4096x2160@60, 3840x2160@120, max Bitrate 80Mbps.

You are welcome.

PS:
By the way its always recommended to look into user manuals for the supported specs of some decoding device. Just so you know where to look in the future.

Are you sure that you are looking at the right model?

In the table "Supported video codecs (QN8**B Series or higher)"

HEVC (H.265 - Main, Main10), 7680 x 4320@60, 3840 x 2160@120, 100Mbps

@Lucius Snow, you probably wanna set both vbv-maxrate and bufsize slightly bellow 100Mbps and adjust avrage bitrate accordingly.

Ah sorry I looked at the wrong table.

I just thought that when I am on the Samsung page of the specific TV and click on 'user manual' that I get the manual for that model and not for all of them. I scrolled around and picked the first table. I am no Samsung TV expert too so I know nothing about TV models.

Yes, I tried these higher bitrates because this 100 Mbit/s limit seemed quite low for 8K 50p. Guess what: I was right. The Samsung internal processor inside the 75QN900B supports my bitrates. Smooth playback!

What bitrate were you able to get to?

I've had 100 Mbps files play without issue on the 900B.
