A warning about your keyframe may appear if you don't use a recommended setting.

What is the recommended keyframe interval?

Most streaming services recommend a keyframe interval of 2 seconds, with some requiring it. Some platforms also recommend a maximum value of 4.

Using a different value may lead to quality issues with your stream.

Why does this warning show up?

The warning alerts you that the quality of your stream may be affected. Recommended settings vary for each platform, and these warnings help maintain balance.

However, if your stream quality isn't affected, you can ignore the warning.

How can I change my keyframe interval?

If your settings are not correct, you can change your keyframe interval in your encoder.

Depending on your encoder, look for settings like:

  • Keyframe every 'number' of seconds - should be set to "2".

  • Keyframe every 'number' of frames - should be 2 x your FPS (e.g., 60 frames for 30 FPS).

  • GOP (or Group of Pictures) - should be 2 x your FPS (e.g., 60 frames for 30 FPS).

If the warning persists despite correct settings and impacts quality, it may indicate connection or CPU issues. Try following the steps here.
