Stream Settings: the basics

In a perfect world, we’d all stream 1080p video at 60fps, and have no delay or glitches. Unfortunately, this is the Internet; it’s unpredictable and imperfect. So how can you get the most out of your quality settings without adding too much buffer? Let’s take a look at what your settings do.



Ideal Settings

If you’re just looking for settings to get you started, below are some common configurations. We’ll go into greater detail below, if you want to understand how to tweak them to suit your needs.

Most video games will stream well with 720p, 30 fps, and whatever bitrate your internet can handle. If you've got a video camera on and the quality seems low, or if you're playing a high action, graphically intense game, you may want to boost that to 60fps.

If you're playing a turn-based game, or coding, or anything that won't update the image as often as a high-action game, the low action settings will give you high enough quality without eating up your CPU or bandwidth. 

 

Note: If you've got settings that should be ideal, but your viewers are still having trouble with buffering, please consider running a traceroute and sending the results to our support team 

 

Resolution

This is what size your video is, but of course you knew that. What you may not know, though, is that if you make use of any automatic resizing in your streaming software, you could lose quality in your stream. It may only be a little bit, but it can add up! We recommend that you keep your game window, base settings, and output resolutions as close to the same as possible.

Tips:

  • Most streamers choose either 720p or 1080p, anything else may look weird in the Mixer player. Adjust at your own risk.
  • Streaming at 1080p increases your packet size quite a bit, so consider reducing your fps and/or bitrate, to prevent your stream from getting caught in internet traffic and causing buffer.

 

FPS

Your Frames Per Second (FPS) or Framerate is how smooth the motion is displayed. For most games, a setting of 30 fps will be just fine. However, for higher motion games like first-person shooters where running, jumping, and quick camera pans are common, an FPS setting of 60 can help keep things super crisp. Make sure to test things out with any changes and get feedback from your viewers.

Tips:

  • Keep in mind that going from 30 fps to 60 fps can be more taxing on both your computer and internet upload.
  • 60 fps likes a higher bitrate to keep the quality clean. We support up to 10000, and your computer, upload speed, and the internet traffic of the day will determine how high you can support on your side.

 

Bitrate

The bitrate setting can be a bit of a double-edged sword, and not the fun kind you swing at bad guys in games. It contributes directly to the video quality of your stream as well as how much of your upload speed your stream will use. Like with anything Internet-related, it’s not a perfect setting so you may see your actual output go up and down while you’re streaming. This is normal, so don’t freak out.

Tips:

  • Mixer supports up to 10000. It is possible to go above this, but you risk dropping stream entirely. It's an industry standard, and may change in the future, but for now, it's safest to stay below this cap.
  • Your bitrate setting shouldn’t use more than 75% of your available upload. This is so you can still use other services while streaming like game servers, email, and music.

 

Keyframe

Of all the settings, this one has the least flexibility yet most significant impact on your upload. To put it simply, the keyframe is how often your streaming software should update Mixer that something is different on your screen. So, if you are playing a game of Chess, a higher value like 2-3 may be sufficient because turns can sometimes take a while and Chess pieces remain relatively static. On the flipside of that coin are games like first-person shooters or fighting games. Most streamers will want to set the keyframe interval to 1 and never look back.

Tip:

  • Many streamers leave their keyframe to 0, thinking this is the smallest value. It's actually an "auto" setting, and can cause serious fluctuation in your stream quality or speed.
