![]() For Facebook Live - The keyframe interval should be 2-4. For Glimesh - The keyframe interval should be 1 or 2. For YouTube - The keyframe interval should be 2. For Twitch - The keyframe interval should be 2. The keyframe interval The Keyframe interval, also known as the I-frame interval, is a setting within the encoder options that determines how often an entire frame is transmitted. Irrelevant to your question but i think if youre affiliate or partner with twitch you cant stream on other platform, not here to arrest you, just. Change the ' Keyframe interval ' - We suggest using 2. Choose 'Output' from the settings window, and then set the output mode to 'Advanced'. For Twitch - The keyframe interval should be 2. Choose ' Settings ' from the bottom Right. ![]() For Twitch - The keyframe interval should be 2. Resolution: 900p NVENC (new) CBR 6000kbps Keyframe Interval - 2s Max Quality High Profile Look Ahead - Off Psycho Visual Tuning - On Max B-frames (currently 4 to experiment) I'm going to try this out with moderately high motion content and see what happens, but I'm hoping you guys can help me at least understand this a bit better. More options that determines how often an entire frame is transmitted. Alternatively, it will convert the processed image and audio data into a filetype for recording. More, also known as the I-frame interval, is a setting within the encoder An encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server. In a constant bitrate rate control video, like the one you configure above, a too small keyframe interval will produce bad quality, because all the bitrate is consumed by the huge key frames, so all frames need to be compressed really high (=detail removed) to fit the bandwidth.The Keyframe interval The Keyframe interval, also known as the I-frame interval, is a setting within the encoder options that determines how often an entire frame is transmitted. In the simple or advanced output mode, you directly enter the number of seconds, since OBS computes the actual interval internally. In the ffmpeg output above, you configure the amount of frames (if you have a 60 fps video, enter 120 to have a keyframe interval of 2 seconds). Too much keyframes bloat the video, and too less makes it unwatchable due to endless seeking.Ī sane value is one keyframe every 1, 2 or up to 10 seconds. So you want a key frame once in a while to make seeking not too slow. If you order a media player to seek to some position, the media player locates the nearest keyframe (I) in the data, then decodes all P frames until it reaches the desired location. These are called predictive coded frames (or P), and these are what makes encoded video data really small. ![]() Frames between key frames contain only the difference between one of the last frames and the current frame, so they are quite smaller. They contain a full frame, so they are huge in terms of space (bytes) needed. Keyframes (or "intra coded" frames, abbreviated with I) are anchors in the encoded frame sequence. Hevc_nvenc and nvenc_hevc are one an the same. ![]()
