What should I set keyframe interval to?

What should I set keyframe interval to?

We recommend a framerate of 25 Frames Per Second (FPS) and a keyframe interval of 2 seconds (or 50 frames). If this isn’t possible, you can also use a framerate of 30 FPS instead. The keyframe interval should never be more than 4 seconds.

What is the best keyframe interval for recording?

2 seconds
Because of this, it’s recommended to have your keyframe interval set at 2 seconds for live streaming. This produces a result where the video track can effectively change bitrates often before the user might experience buffering due to a degradation in their download speed.

What is the best keyframe interval OBS?

Keyframe Interval: For live streaming you will want to set your keyframe interval to 2. What this means is that a full video frame will be rendered every 2 seconds. If you want to learn more about keyframes, head over here.

Does keyframe interval matter for recording?

If you’re just recording, you can use whatever you want. I typically go for a 5 second keyframe interval on my recordings. If you see “keyframe pumping” like Suslik says, then use a smaller interval, but I’ve never seen this at 5 seconds @ 60 fps which is more than the default (300 frames vs default of 250).

How do you fix keyframe intervals?

How to change the Keyframe interval in OBS Studio

1. Open OBS Studio.
2. Choose “Settings” from the bottom Right.
3. Choose “Output” from the settings window.
4. Change the “Keyframe interval”

Does keyframe interval affect performance?

Having a lower keyframes interval means that you will sent more framerate and this needs more bitrate and upload rate. Finding the optimal setting depends on the type of game you stream/record.

How can I make my OBS better quality?

For recorded video production it’s best to choose Lanzos, as this will give you the best quality. The other options are more suited to live streaming. Finally, you’ll need to set your FPS, or frames-per-second. Make sure it fits the framerate you want to edit and output your final video at.

What is the best rate control for streaming?

If you’re streaming, use CBR as every platform recommends it and it’s a reliable form of Rate Control. If you’re recording and need to be high quality, use CQP if the file size is no issue, or VBR if you want to keep file size more reasonable.

Why is obs so blurry?

The cause of the blurriness is your low bitrate. You stream with 2000 bitrate, which is much too low for 720p or 1080p. If you raise the bitrate, make sure you don’t exceed the upload bandwidth of your internet connection.

Can OBS record 120 fps?

Recording 120 frames-per-second (fps) video To record the full 120Hz signal into a 120fps video, other software such as OBS Studio must be used and configured to record at 120fps.

How do I improve live stream quality?

There are a few tricks you can use to improve stream quality:

1. Restart the streaming service.
2. Reboot your home network.
3. Move your Wi-Fi hub and router to an optimal location — somewhere central, open and away from obstruction.
4. Kick some devices off the network.
5. Disable your VPN.
6. Change your DNS server.

What is the key frame interval in encoding?

A key frame interval, also called an i-frame interval, is an encoding setting that determines how often the whole picture is transmitted. When a stream is encoded, only some frames show the complete picture. The initial (key) frame includes a complete image, while subsequent (delta) frames only depict changes from that image.

What’s the interval for a key frame in Wirecast?

In Wirecast, this is set from the Encoder Presets menu and the option is called “key frame every”. Wirecast is different as the interval is actually denoted in frames. So for a 30 FPS broadcast, setting the “key frame every” 60 frames would roughly give a keyframe interval of 2 seconds, as you have 30 frames every second.

When to use delta or key frames in video encoding?

The initial (key) frame includes a complete image, while subsequent (delta) frames only depict changes from that image. This helps reduce redundant data and lower the bandwidth. If your video stream depicts static scenes such as a news desk or talk show, then a keyframe interval of two seconds would suffice.

How often are keyframes written to a video stream?

Assuming that you mean the keyframe interval in the video encoding properties panel (highlighted), this governs how often keyframes are written to the video stream. The default, 18, is one keyframe every 18 frames (or two-thirds of a second.)
