Set OBS’s streaming keyframe interval to 2 seconds for YouTube Live. In OBS, open Settings → Output, switch Output Mode to Advanced if needed, then set Streaming → Keyframe Interval to 2. YouTube recommends a two-second frequency and says not to exceed four seconds. YouTube’s encoder settings
Set the interval in OBS
- Open OBS and select Settings → Output.
- If the keyframe control is not shown, change Output Mode to Advanced. OBS labels and layout may vary by version.
- Under Streaming, set Keyframe Interval to 2 seconds. This meets YouTube’s recommendation and stays within its four-second maximum. YouTube encoder settings
- Select Apply, then OK, if those buttons appear in your OBS version.
The OBS menu path is supported by an older OBS community discussion, so confirm the labels in your installed version; YouTube’s interval guidance is the controlling recommendation. OBS community discussion

Seconds versus frames
OBS’s interval field is expressed in seconds, but some encoder parameters use a frame count. For a two-second interval, multiply the frame rate by two: YouTube gives 30 fps = 60 frames. At a different frame rate, recalculate rather than reusing 60. YouTube encoder settings · YouTube live streaming error messages

Why the setting matters for an always-on stream
A continuous or looping video stream does not call for a different keyframe target. YouTube’s two-second recommendation applies to live encoder settings generally; its guidance does not specify a separate interval for always-on streams. Keyframes mark points in the video stream that help receivers and processing systems begin decoding. Keep the interval at two seconds rather than extending it simply because the broadcast runs for many hours.

ZowieBox enables bidirectional conversion between HDMI and SRT streams, allowing reliable remote production, live streaming, and video contribution workflows with high-quality transmission even across long-distance networks.
The interval is independent of the stream key. The stream key is entered into the encoder so YouTube can accept the feed; it does not alter the keyframe recommendation. YouTube encoder settings
Check adjacent YouTube encoder settings
When reviewing OBS’s streaming output, also check the settings YouTube identifies for ingestion. Its encoder settings page lists RTMP/RTMPS as protocols and CBR as the recommended bitrate encoding. Use YouTube’s full guidance for the appropriate bitrate and resolution for your stream rather than changing those values to compensate for a keyframe issue. YouTube encoder settings

Troubleshoot a keyframe-frequency warning
- YouTube says keyframes are too frequent or too far apart: Set the encoder to produce one every two seconds. If YouTube still reports an error, check the actual encoder output and GOP behavior; a displayed OBS value may not be taking effect as expected.
- A frame-based parameter is configured: Convert the target to frames using frame rate × 2. At 30 fps, use 60 frames; recalculate if the frame rate changes.
- The observed GOP size is wrong despite the setting: YouTube notes that ingestion errors can affect GOP size and says a closed GOP is required for optimal transcoding. Check the encoder’s effective output and the stream health messages in YouTube Live Control Room. YouTube live streaming error messages
- The control is missing in OBS: Check whether Output Mode is set to Advanced and look under Streaming. Menu wording can differ between OBS versions.
Before a long broadcast, test with representative audio and motion, then review YouTube’s stream health messages. YouTube recommends testing and monitoring stream health
