  • Streaming address: Kollus Live console > [Channel] > [Channel list] > Select channel > [Application link]
  • Stream key: Kollus Live console > [Channel] > [Channel list] > [Edit] on the right of the target channel > [Creator code] tab at the bottom > [Creator stream key]

Pixelation Prevention Settings​

Pixelation may occur when streaming content that includes presentation materials such as annotations or PPT slides, or when streaming video with lighting changes or fast movement. To maintain stable video quality, please change the settings in OBS as described below.

Keyframe Interval Settings​

A long keyframe interval can slow down video quality recovery during scene transitions. Therefore, the following settings are recommended.

  • Settings path: [Settings] > [Output] > Select [Output Mode] as [Advanced] > [Streaming] tab > [Encoding settings] > [Keyframe Interval]
  • Value: 1s

Common FPS Values Setting​

If the frame rate is too high, pixelation may occur due to insufficient bandwidth. 30 FPS is appropriate for general lectures or broadcasts.

  • Settings path: [Settings] > [Video] > [Common FPS Values]
  • Value: 30

Service Bitrate Settings​

To prevent video quality degradation in the final service, the original streaming bitrate must be kept higher than the Kollus encoding settings. It is recommended to set the OBS streaming bitrate higher than the maximum bitrate of the Kollus encoding profile.

Step 1: Check the Bitrate​

In the Kollus Live console > [Settings] > [Profiles], check the maximum bitrate value of the profile in use.

Step 2: Configure OBS Bitrate Settings​

  • Settings path: [Settings] > [Output] > Select [Output Mode] as [Advanced] > [Streaming] tab > [Encoding settings] > [Bitrate]
  • Value: Enter a value higher than the maximum bitrate of the Kollus encoding profile confirmed in Step 1.
