The keyframe interval in OBS determines how often complete frames appear in your video stream. It determines the streaming quality and video compression efficiency. This setting directly impacts your streaming performance and viewer experience across different platforms.
You must understand keyframe intervals to optimize your streaming videos for better quality. The right keyframe setting ensures smooth playback and helps maintain consistent video content delivery. It becomes especially important when dealing with varying network conditions and bandwidth usage.
Many streamers overlook this essential setting, which can significantly affect your live or on-demand content. A proper keyframe interval helps your stream adapt to network fluctuations and high-latency connections. This optimization is particularly valuable for viewers with unstable internet connections.
We recommend adjusting your keyframe interval based on your specific streaming scenarios. The ideal setting depends on your bitrate requirement and target platform. Most streaming scenarios benefit from a keyframe interval of 2 seconds, which most platforms recommend.
This guide will walk you through changing your OBS keyframe interval. You will learn to optimize this setting for better streaming quality and viewer experience.
What is Keyframe Interval in OBS Studio?
The interval works with three types of frames:
- I-frames
- P-frames
- B-frames.
While I-frames contain full frame data, P-frames and B-frames only store the differences from the previous keyframe. This system helps reduce bandwidth usage while maintaining video quality. You can adjust this setting to balance between stream quality and performance requirements.
