What is Encoding?

Simply put, encoders allow you to convert your video files from RAW to digital in order to prepare it for transmission from your camera to live streaming 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.

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

What is OBS Studio?

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 OVP (online video platform). 

One popular and free option is OBS Studio. This open-source application allows users to capture and stream live video from any Mac, Windows, or Linux computer.

OBS Studio offers many great features for new broadcasters who are just getting the hang of live streaming. These features include the ability to mix multiple sources with custom transitions, use audio/video filters and correction tools, and more. 

OBS Studio is especially easy to use for Dacast users since Dacast has created a custom OBS Studio portal that is free for our users.

Best OBS Studio Settings to Configure Your OBS Encoder

There is a very specific way to configure the OBS Studio settings for live streaming on a Dacast HTML5 live channel. 

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, here, you can choose your language and select a light or dark theme. 

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

Keep in mind, however, that the checkboxes may be important. Check both boxes to avoid accidentally starting or stopping your stream before you’re ready.

Once you’ve reviewed these settings, click on the next tab labeled “Stream” in the OBS Studio settings window. 

For “Stream Type,” you should see “Custom…” by default. If not, please select it. Next, you need to enter the data provided in your Dacast account.

Next steps are as follows:

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. Then, you have to do the same for “Server,” which is copied in Stream URL. You will repeat this for the username and password.

Top 4 Best OBS Studio Settings for Audio and Video

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

These are the required settings:

In addition to these required live encoder configuration settings, there are a few other suggested settings to optimize your audio and video streaming.

1. Simple Output Mode

To change the encoding settings, you will have to open the Output settings. By default, the selected output mode is Simple. To ensure your Dacast live stream is stable and fully functional we recommend you follow the configuration settings shared in the “Encoder Setup” window. 

When using this output mode, you only need to focus on the video bitrate and the audio bitrate.

By default, the audio bitrate and the video bitrate will be in low definition. Of course, you can select a higher video quality if you choose.

When doing so, please make sure that your combined audio and video bitrates are less than half your internet upload speed. Otherwise, you’ll run into buffering issues.  

For example, if your internet upload speed is 2000 Megabit per second, then your audio and video bitrates should not be higher than 1000 Megabit per second. 

To learn more about our recommended bitrate settings for various resolutions for secure video upload, check out our support site post.

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

2. Advanced Output Mode

If you opt to select the “Advanced” output mode, you’ll get access to more options for the best OBS Studio setting. To ensure a quality stream, you should review the screenshot below. 

Pay close attention to ensure that your output mode is “Advanced,” the rate control is set as CBR and the keyframe interval is equal to 2. 

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

3. 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.

4. Video source

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

Conclusion

Choosing the right encoder settings can be confusing at first. Luckily, OBS Studio is free software that will allow you to test out the features without investing any money.

We believe that you’ll have a smooth experience if you follow these recommendations on the best OBS studio settings to get started. After a little experimenting, you’ll have no problem navigating the platform.

With these recommended settings as your starting point, getting comfortable doing live streams should be straightforward and enjoyable.
