OBS Studio Setup Tutorial

OBS Setup:

OBS is a stand alone free streaming encoder, and should not be used in conjunction with the Vaughn.live built in Go Live now or Start Stream option. All streams using OBS should be started from the Start Streaming button on the OBS main screen.

SUGGESTED ENCODER SETTINGS can be found in the table below.

Getting Started:

You will need both your Ingest Server URL and your Stream Key. Right click link below and open in a new tab . Leave this page open  to copy the settings used in the next step. Select the Ingest server closest to your physical location.

https://vaughn.live/settings/channel

  1. On the  main OBS Screen click settings.
  2. Next click Stream in to column to the left.
  3. Top line Service select Custom .
  4. Copy the rtmp url from the channel settings page we opened previously and paste where it says URL.
  5. Copy the stream key from the channel settings page and paste where it says Stream Key. Never allow other to see your stream key as it will allow them to stream to your channel with no login required.
  6. Click Apply
  7. Next select Output from the column on the left in the OBS settings page.
  8. In the line where it says Output Mode select Advanced.
  9. On the second line make sure streaming is highlighted.
  10. On the line that says encoder select x264.
  11. On the rescale output line check mark the box that says Rescale Output.
  12. In the drop down box to the right select the drop down arrow to the right and select the resolution you want your stream to be. If the size you need isn’t listed then manually type it in. Eg. 640×360, 1280×720 etc. In the Rate Control box select CBR. In the Bitrate box use the up/down arrow keys to select your bitrate or manually type it in. Eg. 1000kbps.
  13. In the Keyframe Interval (seconds, 0=auto)  make that value 2.
  14. On the CPU Usage Preset select veryfast
  15. On the Profile line select high. Leave all other settings on that page the default value. (It’s very important that rate control is CBR and the keyframe is 2). Either of those set to the wrong value can cause buffering issuse on your stream.
  16. Once you have all of that setup click apply to save the changes.
  17.  Next select to Video tab in the obs settings. The top line Base (Canvas) Resolution as is, it will default to your current monitor resolution.
  18. On the second line Output (scaled) Resolution select 640×360 from the dropdown menu or manually type in the value 640×360 in the box.
  19. The third line should say Downscale filter: select Bicubic (sharpened scaling, 16 samples).
  20. The forth line is the Common Fps Values  30 or 60  either one is fine.  60 typically isn’t needed except for certain things like gaming.
  21. Click apply the click OK.
  22. You OBS should be ready to stream.
