OBS rescaling output results in missing 480p and 240p for YT

[SAB612]

Hello,

i have two 1440p monitors (16:9) and i stream with the output rescaled to 1080p in the Output tab. CBR bitrate is 8.000 kbit/s which is a bit higher than the suggested bitrate for Twitch (6.000). I do record with CQP 24 and with no downscaling. If i download the VOD afterwards and upload (either parts of it or entirely) to YT, it will result it being only 144p, 360p, 720p and 1080p. 240p and 480p are missing completely. When i did stream with 1440p (which i discontinued due to the video not looking that great), the video would be available in 144p, 240p, 360p, 480p, 720p, 1080p and 1440p. This even applies after i edit the video in a program like DaVinci or Avidemux (which i sometimes do to accelerate processing at YouTube or if i need to edit something).
I only did change the setting that sets the quality to CQP 24 (recording) and CBR to 8.000 kbit/s and rescale output is checked and set to 1920 x 1080.
Now i know that these two resolutions are not that good in quality, but 480p is a good compromise if your internet is not that fast and you still want some quality.
Is there a mistake i'm making in the OBS setting or is it just a thing on the YT side?

I checked a few of my videos and it's a thing on the YT side.

Ok, i did some digging and it seems it is a YT thing. YT transcodes your videos after uploading and compresses them. They use 3 codecs as of now: H.264 aka. AVC1, VP09 and AV01. For some reason, if the chosen Codec is H.264, YT will not transcode it into 480p and 240p. Only if it the codec is VP09 or AV01.
Smaller channels usually get H.264, unless you upload in a higher resolution than FHD. If you upload in QHD (1440p), your video gets the VP09 codec (usually), no matter the size and hence YT also transcodes it into 480p and 240p. Same goes for AV01, although i noticed that videos that have AV01 as codec and have a resolution higher than 1080p will get two codecs. VP09 for 1440p and 2160p and AV01 for 1080p and below.
VP09 and AV01 for FHD videos seem to be used for larger channels.
