Extremely jittery video input when using OBS?


New Member
Recently I've been trying to stream from my PC rather than from my Laptop. Whenever I do however the video is extremely jittery as can be seen here: https://www.twitch.tv/videos/742754059

I've followed all of the advice in this video but unfortunately the problem still persists: https://youtu.be/Cz1nbD-0y0A
Has anyone else experienced this problem and if so, how did you solve it?
Here is the Log file after a 20 minute stream: https://obsproject.com/logs/5p_qQjdiTkrJbwsY
The stream was jittery then after about five minutes elgato displayed no input detected before switching to one moment please and then remaining on that screen for 15 minutes.
