What is Encoding?

Simply put, encoders allow you to convert your video files from RAW to digital to prepare them for transmission from your camera to your live streaming platform host. Along with a recording device and reliable internet, a functional encoder is a must for broadcasters.

Encoders come in the form of both software and hardware. Software encoders are typically free or low-cost, but hardware encoders can get quite expensive.

Research shows that 67% of viewers rank video quality as the most important factor in a live stream. As a broadcaster, you can ensure high-quality video content for your viewers by choosing the best OBS Studio settings before you go live. 

What is OBS Studio?

OBS stands for Open Broadcaster Software, and it’s an invaluable resource for anyone looking to maintain exceptional video recording quality in the content they create. For broadcasters and content creators, regardless of their experience level in video-making, OBS studio is easy to use for multi-platform screen casting and streaming. The only investment required is the time to learn optimal OBS settings for streaming and video recording.

OBS Studio is a free, open-source RTMP-enabled encoder software perfect for new and experienced broadcasters. This open-source live streaming software allows users to capture and stream live video from any Mac, Windows, or Linux computer.

RTMP stands for “Real-Time Messaging Protocol,” and it is part of the technology that makes live streaming possible. RTMP’s primary role is to deliver content from an encoder to an online video host. This RTMP function is referred to as “RTMP ingest.” For OBS, the RTMP protocol bridges the gap between its encoding and streaming functions.

As we mentioned, professional live streaming requires either a software or hardware encoder. This equipment works to encode a live video feed into the correct format for streaming through your online video platform (OVP).

OBS Studio offers many great features for new broadcasters just getting the hang of live streaming. The software has a set of OBS-specific system requirements to ensure the most optimal live broadcasting experience. These settings include mixing multiple sources with custom transitions, using audio/video filters and correction tools, and more. 

The latest version of OBS is OBS Studio 29.0.2 was released on February 4th, 2023. It is free to download for macOS 10.15 or newer and supports both macOS(Intel) and macOS(Apple Silicon), Windows 10 and 11, and Ubuntu 20.04 operating systems or newer. For the Linux version, FFmpeg is required.

OBS Studio is especially easy to use for Dacast users since we’ve created a custom OBS Studio portal that is free for our users. This article will help you configure the best OBS settings for your streaming content. 

Why Do OBS Settings Matter?

Choosing the right OBS settings can make a huge difference in the quality of your recording. If your settings are too low, your video may be blurry, pixelated, or choppy. On the other hand, if your settings are too high, your video may be too large, take up too much space, or be difficult to upload and share. Finding the right balance is key.

How to Configure Your OBS Studio Settings 

There is a precise way to configure the OBS Studio settings for live streaming on an HTML5 live channel. Here’s a quick tutorial on optimizing OBS settings for streaming:

First, open the OBS Studio settings by clicking the “Settings” button in the bottom-right area of the application window.

The first tab, labeled “General”, doesn’t have anything too critical to review. However, you can choose your language and a light or dark theme here.

Although the language and theme may seem insignificant, it is important to have your bases covered to avoid any issues in your stream. Check both boxes to avoid accidentally starting or stopping your stream before you’re ready.

Next up is the “Streaming” tab, where the magic happens. To access the streaming tab, click on the next tab labeled “Stream” in the OBS Studio settings window. The streaming tab is where you can select your streaming service. In this case, Dacast. 

For “Stream Type”, you should see “Custom…” by default. If not, please select it.

Next, you need to enter the streaming credentials provided by your online streaming service including the stream URL (server), stream key, username, and password. You can find these credentials on your OVP’s streaming encoder setup page.

On Dacast, fetching these credentials looks like this:

1. Go to your Dacast account, and open or create the channel you want to live stream with OBS. Open your “Encoder Setup”.
2. You will choose “Stream Name”, click on copy and go back to OBS to paste the key in the Stream Key field.
3. You have to do the same for “Server”, copied in the Stream URL. Repeat this for the username and password.

Best OBS Studio Settings for Streaming Audio and Video

To stream with the best quality possible, it is essential to choose the best settings for your video encoder. Changing quality settings to optimize streaming is easy with OBS Studio; just use the Video tab and Audio tab to configure these settings.

Your encoder is responsible for the audio quality recorded from your external microphone and audio track. It also ensures the video quality of your live streams is as high as possible, depending on the CPU usage preset.

Here are a few of the best OBS settings for streaming audio and video content.

1. OVP-Specific Setting Requirements

Different online video platforms have different encoder setting requirements. That’s because each video or multi stream platform uses different technology to bring streams to life. Another reason is differences in requirements such as stream quality, video resolution, and the built-in CPU usage preset in the broadcaster’s system. That’s why selecting your OVP according to your needs and desired output as a broadcaster is important. 

Dacast, for example, has a few required OBS settings that apply to this and any other encoding software you may use.

These required live encoder settings include:

VIDEO CODEC	H.264 (x264 may work)
FRAME RATE	25 or 30
KEYFRAME INTERVAL	3 secs (or 3x frame rate)
SCANNING	Progressive
ENCODING BITRATE	Constant Bitrate (CBR)
AUDIO CODEC	AAC
AUDIO BITRATE	128 kbps
AUDIO CHANNELS	2 (Stereo)
AUDIO SAMPLE RATE	48 kHz (48,000 Hz)

2. OBS Output Settings

To change your OBS Studio settings, you must open the “Output Settings“ in your OBS Studio account. 

In the default settings, the selected output settings tab is selected as “Simple”. To optimize your OBS settings for streaming and to ensure your live stream is stable and fully functional we recommend you follow the configuration settings shared in the “Encoder Setup” window, pictured below:

Customizing these settings through the video tab and audio tab will ensure higher video quality and audio quality for your stream. In this output mode, you only need to focus on the video bitrate and the audio bitrate to optimize output resolution. 

By default, the OBS audio bitrate and video bitrate settings will be in low definition. Here, you can control your stream quality by selecting the optimal video bitrate to broadcast high-quality video. 

Our suggested video OBS bitrate settings for different resolutions include:

	ULD	LD	SD	HD	FHD
Name	Ultra-Low Definition	Low Definition	Standard Definition	High Definition	Full High Definition
Video Bitrate (kbps)	350	350 – 800	800 – 1200	1200 – 1900	1900 – 4500
Resolution Width (px)	426	640	854	1280	1920
Resolution Height (px)	240	360	480	720	1080
H.264 Profile	Main	Main	High	High	High
Audio Bitrate (kbps)	64	64	128	256	256

Let’s take a look at the audio settings now. You can easily customize these settings from the audio tab. You can add any audio device, such as desktop audio or external microphone. If you are only streaming audio, you can get away with OBS bitrate settings as low as 64 kbps. However, you should up your audio bitrate settings to 192-320 kbps for better audio quality. 

We recommend downloading OBS Lua, which is an OBS-specific bitrate calculator. That’ll help you find the best OBS settings for your streaming needs.

3. Bitrate and Internet Speed

As you manipulate your bitrate settings, it is essential to consider your internet connection. 

Your internet speed must be at least double your OBS bitrate if you want to produce a high-quality stream. Otherwise, you’ll run into buffering issues. Video quality isn’t the only element that defines the overall experience your content delivers to your viewers. Streaming with no buffering should be equally important as high video and audio quality. 

For example, if your internet upload speed is 2000 Mbps, then your OBS setting for streaming, audio, and video bitrates should not exceed 1000 Mbps.

You can search “internet speed test” on Google and click “RUN SPEED TEST” to test how fast your internet is. 

Additionally, you can test your internet connection speed by going to the website testmy.net.

4. Advanced Output Mode

Advanced settings and rate control can also be accessed and changed through the output tab to produce better-quality streams. If you select the “Advanced” output mode, you’ll get access to more options for the best OBS settings. To ensure a quality stream, you should use the following settings:

Pay close attention to ensure that your output mode is set to “Advanced”, the rate control is set as “CBR”, or constant bitrate, and the keyframe interval is equal to 3.

The other setting on the Output OBS Studio settings page relates to recording your broadcast. This feature enables you to record the live stream to a local drive as you stream. 

We recommend enabling this setting if you haven’t set up an auto-archiving feature with your live streaming platform. Use “Same as Stream” or “Indistinguishable Quality” for recording quality, “mp4” for recording format, and “x.264” for the encoder.

5. Hotkeys

Hotkeys allow you to set up different scenes within your live stream encoding software. That way, you can switch between the scenes during your live broadcast.

How you configure your hotkeys will depend on your specific needs. For example, you could set up hotkeys for specific overlays and inputs.

There are several default hotkeys on OBS Studio, but they are turned off by default. You can check out the documentation for using hotkeys for streaming with OBS Studio on GitHub.

6. Video Sources

To add a video source, click on the “+” button in the “Sources” widget. You can select a display capture, video capture device, image, recorded video, etc. When you’re ready to stream live, click “Start Streaming”.

7. OBS Recording Settings

Recording streaming video and audio is a handy feature that lets broadcasters re-use live-streamed content with OBS Studio. Accessing this tool is very easy. Users must simply click “Start Recording” in the screen’s control panel in the lower right-hand corner.

To access your stream recordings, click “File” on the top left-hand side of the screen and choose “Show Recordings”. If you’re using Windows, it’ll send the stream recording directly to your computer’s “Video” folder.

OBS Studio vs. Streamlabs OBS

While we’re on the streaming software and the best OBS settings, let’s quickly discuss Streamlabs OBS, which is software similar to OBS Studio.

Streamlabs OBS is a free and open-source streaming software designed for stream layout editing, replay buffer, selective recording, and remote streaming control.

Users can upload to Streamlabs Prime to access premium features. This upgrade costs $19/month or $149/year.

Streamlabs OBS is a better option for beginners or broadcasters with little technical know-how since it has a graphical user interface (GUI). On the other hand, OBS Studio has a command-line interface (CLI) that requires users to use coded commands to execute functions.

Although Streamlabs is easier to use and provides the option to upgrade for access to premium features, many broadcasters prefer OBS Studio since it is more extensible.
