After you downloaded and installed Open Broadcaster Software Classis/Studio please open OBS and click on "Settings":

 

Go to "Output" on the left

Output Mode: Simple

In the "Simple" output mode you can edit all the settings essential to stream, such as the video/audio bitrate and encode. You can start your livestream by setting the "Video Bitrate" to 350. If the stream quality is not good enough for you, you can increase it later on. Please keep in mind that higher bitrate requires a faster internet connection. Your audience might see a stuttering stream or even frozen screens if you set the bitrate too high.

You don't have to change the audio bitrate for art live streams. If you are streaming music, an increased audio bitrate might bring better quality to your live stream audio. It all depends on your own internet connection.

 

Output Mode: Advanced

1. If you display fast movements during your streams (such as animations) you can also disable CBR to save bandwidth.

2. Max bitrate should be set according to our streaming standards, but not more than 3500. Also it is very important that your bitrate is not higher than your own internet upload speed, otherwise you will suffer frame drops.

To find how much upload speed you have you can do a speedtest here: http://www.speedtest.net/

We recommend the following bitrates for different resolutions:

Your Upload

Resolution

Bitrate in kbit/s

Keyframe intervall

under 1 Mbps

480p

350 - 500

4

1.5 Mbps - 5 Mbps

720p -1080p

500 - 800

2

over 5 Mbps

1080p - 4k

1000 - 2000

1

If you have a very slow connection to begin with, set the Keyframe intervall to 4 or 8. Be aware that this will increase your video loading time, but will guarantee a more stable stream.

 

Broadcasting

Now you need to type in your Picarto credentials for streaming. You can find these in our livestream setup tutorial by clicking on the "Go Live" button at the top right corner and following the setup tutorial.

The final step would be choosing the server and copying the stream key.

  • Please click on Show all Services.
  • Click on Service and select Picarto.
  • Paste your Stream key into the "Stream key" section.

 

 Video Settings

Output (Scaled) Resolution is the final resolution you are sending to our servers. If you choose lower resolutions this can help reducing your processing (CPU) power as well as the use of bandwidth.

FPS can remain at 30, but it's also possible to lower them down to 24 to save CPU processing and bandwidth.
