What is keyframe interval?

The keyframe interval controls how often a keyframe (i-frame) is created in the video. The higher the keyframe interval, generally the more compression that is being applied to the content, although that doesn't mean a noticeable reduction in quality.

What is keyframe interval for live streaming?

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 affect performance?

Strictly speaking, longer keyframe intervals should result in better quality for the bitrate, but there's diminishing returns, and in the context of live encoding, its not worth going crazy on.

What does keyframe interval too high mean?

Let's say it's 2 minutes between I-frames -- that means if you're watching and have a slight hiccup in your connection, it's going to take upwards of 2 minutes before you can start viewing again.

Does keyframe interval matter for recording?

Bitrate for recording and streaming should be set from 4000 Kbps to 6000 Kbps depending on your bandwidth, frame rate, and video resolution. Plus, note that Keyframe Interval should be set at 2, meaning that the video frame will be rendered every 2 seconds.

Advanced OBS settings - Keyframe interval - CPU preset - Downscale filter

How many keyframe intervals should I use?

Streaming programs like OBS and XSplit let you set your Keyframe Interval manually, and for the most part, you're going to want to stick to 2. This value means '2 keyframes every second'.

What is a good keyframe interval for OBS?

Because of this, it's recommended to have your keyframe interval set at 2 seconds for live streaming.

How can I make my stream quality better?

8 OBS tips to make your stream run smoothly
  1. Use your Graphics Card for Encoding.
  2. Load your Overlay from a single Browser Source.
  3. Adjust Video Bitrate.
  4. You can set your Video Bitrate in Settings > Output > Streaming.
  5. Advanced Encoder Settings.
  6. There are a couple of hidden settings within Settings > Output > Streaming.

What audio bitrate should I use OBS?

OBS Output Settings

Of course, you can select a higher video quality if you choose. If you are only streaming audio, you can get away with bitrate settings as low as 64 kbps. However, for better quality, you should up your audio bitrate settings to 192-320 kbps.

How do keyframes work?

A keyframe marks the point in time where you specify a value, such as spatial position, opacity, or audio volume. To create a change in a property over time, you set at least two keyframes—one keyframe for the value at the beginning of the change, and another keyframe for the value at the end of the change.

What is high motion quality boost OBS?

With their new Navi GPU series AMD added a new feature to the hardware encoders: High Motion Quality Boost. This option should allow you to get higher quality streams at the exact same bitrate, resolution and framerate, given that you own and use an AMD RX 5700 (XT/XT Anniversary).

How do I improve stream quality on OBS?

Here are some ways you can reduce resource utilization and, hopefully, make both OBS and your programs run faster while encoding:
  1. Downscale your output resolution. ...
  2. Lower your frame rate. ...
  3. Change your x264 preset. ...
  4. Try Quicksync, AMF, or NVENC. ...
  5. Check your sources. ...
  6. Upgrade your hardware.

What bitrate should I stream at for 1080p 60fps?

The best bitrate for 1080p 60fps on Twitch is 6,000 kbps provided if you have a strong internet connection. However, you can opt for 1080p 30fps that requires at least 4,500kbps if you have a slower connection.

Why is my OBS so laggy?

The reasons why your OBS lags depend on when you're experiencing the lag. If you're experiencing lags when streaming, culprits often boil down to network latency. But if it keeps lagging even if you're recording, or exporting your videos, it's mainly caused by your graphics card.

Which encoder is best OBS?

The (New) Nvenc encoder is easily the best OBS encoder available, assuming you have a modern NVIDIA graphics card with the improved ASIC chip. With zero performance impact while encoding and high-quality frames even at low bitrates, it is a strong contender as a streaming encoder.

How do I get more FPS while streaming?

How To Improve FPS While Streaming
  1. Adjust Game Settings. Even if you have a really good computer your game settings may be too high to play and stream at the same time. ...
  2. Lower Your On Stream Production. ...
  3. Update Graphics Drivers. ...
  4. Close Any Unnecessary Applications. ...
  5. Upgrade Your PC.

Which bitrate is best for video?

For regular HD videos with a standard resolution, set bitrate between 2,500 to 4,000 kbps. For full HD videos with high resolution, set bitrate between 4,500 to 6,000 kbps. For regular HD videos with high resolution, set bitrate between 3,500 to 5,000 kbps.

What causes low bitrate?

Network congestion is the main culprit. Having a static bitrate can cause frames to drop because your connection is unable to keep up and will drop frames to improve the stability of your stream and minimize latency.

What does keyframe interval Do blender?

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.)

What bitrate should I stream at 720p?

For 720p video at 30 frames per second, bitrate should be between 2,500 and 4,000 kbps. That requires upload speeds between 3.2 Mbps and 5 Mbps. For 720p video at 60 frames per second, the bitrate should be between 3,500 and 5,000 kbps.

Does GPU affect streaming?

Graphics Card

Although GPUs do not directly affect the streaming quality, having a low-end GPU means you have to play on lower settings for a smooth experience.

What are the best OBS settings?
