YouTube Original resolution HQ38

While searching for a special soundtrack I stumbled accross a youtube video promoting the use of the "original quality" - these vids are still rare but make sense if the audio source was excellent and you're into great sound quality.

The original setting features either a 2k or a 4k video feed and cristal clear audio. Here are some example stats of what the stream packs in for you:

Name: Original  also HQ38
aka: 4k  or  4096p  or  2k, 2048p

Container: MP4
Video Codec: H.264(mpeg4 part 10)
Resolution: 4k - 4096x2304 (~xxxx kbps)  or  2k - 2048x1152 (min. 1570 kbps)
Aspect Ratio: 16:9
Audio Codec: AAC 151+ kbps VBR, 44.1kHz stereo 

So far I only saw 2 channel audio feeds, what is actually fine with me, because I mainly feed the earphones only. The rest of the youtube codecs and how to record videos and extract audio is described here.

(interesting: transcoding with lame.exe delivers catastrophic results for the first 10s)
