I found it difficult at first too, but once you figure it out, it's all good. Go to your settings and then to the encoding tab, if you are getting motion blur or pixelation under speed, lower the quality balance to around 2 or 3, that will solve it. Go to broadcast settings and set the mode to File Output Only, then set up where you want the file to go and what name to put it under. I put mine into My videos, filename SC2. Also setup hotkeys for starting and stopping. Also set it to an MP4 when you are setting up the file path and name. Under the video tab, you can set what resolution you want it to record at. Make sure that your game is open and you are alt tabbed to the desktop. Next go back to the main page of OBS and right click in the sources box, then click add. Select game capture, name it, then set the application to the game that you are playing. Make sure that it's checked and you are all set. After you start, then stop the recording, it will make an MP4 file and then you can upload that directly to youtube.
