How-to-broadcast-to-Youtube-in-perfect-1080p-using-obs

Download OBS: https://obsproject.com/

The first part of the trick is using Youtube HLS instead of Default RTMP Stream Key.
The second part of the trick is using Stream Key instead of Recommended "Login into Youtube's"
The third part of the trick is using Youtube HLS in the OBS. It is actually supported!
The final part of the trick is recording screen in 1080p 60 fps and broadcasting it to Youtube in 4K by manually setting resolution in Youtube's Stream Key.

Setup a HLS Stream Key on Youtube. (Youtube' Go Live)

Open Youtube's Go Live: https://www.youtube.com/live_dashboard

Select Stream Key - Create new Stream Key:

Streaming protocol: HLS (Advanced)
Turn on manual settings: Yes
Resolution: Resolution: 4k (30Mbps)
Turn on 60 fps option: yes

Use Youtube's Stream Key in OBS

Finding HLS Stream Service Option in OBS (Youtube - HLS)

Activating Youtube's Stream Key in the Youtube - HLS Service on OBS

Paste Youtube's Stream Key into OBS

Tick "Ignore streaming service setting recommendations"

Open "Output" settings tab in OBS and increase Video and Audio bitrates

OBS - Settings - Output - Streaming:
Video Bitrate: 30000Kbps Audio Bitrate: 160Kbps

Now you are ready to stream to Youtube in 1080p 60FPS

The youtube's video will have video options above 1080p: 1440p and 4K
But that's just streaming resolution, not the recording resolution your computer will record.

To select recording resolution:

OBS - Settings - Video: Base canvas resolution: 1920x1080 Common FPS value: 60

Setup stream Hotkey

I prefer to use CTRL + ALT + A to start and stop the stream.

Bonus: Game Streaming

OBS Sources: Game Capture + Application Audio Capture
OBS Plugins: win-capture-audio v2.2.3-beta

Always remember to launch OBS on the same dedicated GPU on which your game is running.
Do not use integrated video card unless you can run Stream/record and game on it at the same time.
If you will try, to run OBS and Game on different GPUs - Source: Game Capture will see and record only black screen.

If you see black screen in the OBS preview: Try to fullscreen the game and move around the menu of the game to initialize the OBS preview.

Example of Game Capture

Game capture is part of OBS software installation.

Example of Application Audio Capture

This is a OBS plugin and is not part of OBS itself.

Bonus: Downloading streamed content

Even if the stream is over, the video is segmented and need to be downloaded and merged into single video.
