obs:
- video: output to 1080p at 59.94fps - because that's what the camera outputs
- advanced, Filename formatting: "obs" (so that the recording file doesn't change all the time)
- output, recording
- format: mpeg-ts (works well for streams)
- encoder: H264 hardware encoder (easier on the battery)
- rate control: CBR
- bitrate: 20000 kbps (more than that will cause the video in the file to lag if it is being read at the same time)
- keyframe-interval: 2s (easier to pick-up lost streams)
- start recording
ffmpeg:

done- start reading the recording at the end of the file (-sseof -1)
- use hardware-h265 encoding for high quality per bitrate
- set the bitrate to the one suggested by youtube for 1440p streams
- reduce that bitrate if it is to much for the internet connection
- set the max bitrate to whatever the internet connections allows to prevent stuttering
- motion-interpolate the 59.94 fps video to 60 fps to prevent stuttering
- upscale the video to 1440p so youtube gives it more bitrate
- stream the video to youtube
