Change the keyframe interval in OBS
- Open OBS settings: Click Settings, then select Output.
- Show the streaming controls: If Output Mode is set to Simple, change it to Advanced.
- Find the streaming encoder setting: Open the streaming output section or tab and locate Keyframe Interval. Its exact position and automatic behavior can vary by OBS version, output mode, and encoder.
- Enter 2 seconds: Set the interval to 2 when the control is expressed in seconds, then apply the change. YouTube’s current live encoder settings recommend 2 seconds and say not to exceed 4 seconds.
- Test the stream: Before an event, test with representative audio and motion. During the stream, check YouTube’s stream-health feedback. If OBS offers Enforce streaming service encoder settings, leaving it enabled may let OBS apply the platform’s recommended settings.
Seconds and frames are not interchangeable
The OBS interval control may be seconds-based, but a custom encoder parameter named keyint can be measured in frames. For a two-second interval, multiply the output frame rate by two: at 30 fps, use 60 frames; at 60 fps, use 120 frames. Entering 2 in a frame-count field means two frames, not two seconds.

OBS’s documentation for NVENC custom options in OBS 31.0 describes keyint as an interval in frames and notes that 1 is a special value for intra-only mode. Prefer the seconds-based OBS field when available; check the documentation for your selected encoder before changing custom parameters.

What the setting does—and does not do
A keyframe is a reference point in the video stream. Keeping the interval consistent and within the platform’s recommendation can help YouTube transition between transcoded quality options. It is one encoder setting, not a general fix for stream problems. YouTube’s live encoder guidance also covers supported codecs and CBR for RTMP/RTMPS streaming.

If YouTube reports that keyframes are too far apart, verify that you changed the streaming encoder setting—not a recording-only control—and confirm the stream is using the updated settings. Restart or refresh the stream if needed, then check the current stream-health feedback. Changing the interval alone will not necessarily fix buffering, an unsuitable bitrate, network instability, or encoder overload.
