This article details how to use Open Broadcast Software (OBS) to send your video stream to the Field59 live stream platform.

Before you download OBS, first check that the computer you are installing it on has the required specs. Any modern — or even not so modern — computer can live stream. At a minimum, you need an inexpensive video card, and we recommend at least 1 GB of RAM. You also need to be able to connect to the computer the camera you are using, and to an Internet connection. We recommend a wired Internet connection, although you can also stream over wifi or data. Once you have that set up and OBS installed, here are our recommended settings.

After installing, open the application to get to a view like this:

Before you can begin streaming, you must first input your live stream publish information (and perhaps adjust other default settings). Click the Settings button at lower right.

Stream

Set the Service drop-down to Custom. Under Server and Stream Key, enter your Field59 publishing information.

Output

The screenshot above shows a view when you set Output Mode to Advanced (instead of Simple). Set Encoder to x264. For Rescale Output, use 1280×720 (this is typically the high output for a Field59 stream). We recommend a Keyframe Interval of 2. A recommended Bitrate is 2000 kbps (2 Mbps) for mostly static scenes. You may want to increase to 3000 kbps (3 Mbps) for events with lots of movement, such as sports. Keep in mind Field59 will pass through your source bitrate setting on the high output from the Field59 live cloud, so many users will consume stream bandwidth at the bitrate level set here.

Please check the bandwidth available on the Internet connection you are using at your streaming location before starting your stream — you should be careful not to exceed the bandwidth available to you at your location, or the stream will have difficulty getting to our cloud platform for transcoding and distribution.

(Note: Field59’s transcoding platform takes your source input feed and converts to adaptive bitrate streams that provide high- and low-bandwidth options for viewers. The high option will typically be your source stream. Users on limited connections will most likely always receive the low-bandwidth stream, which is commonly in the 1000 Kbps (1 Mbps) range.)

Audio

Use default audio settings (Sample Rate: 44.1 kHz, Channels: Stereo)

Video

For the Base Resolution and Output (Scaled) Resolution settings, we recommend 1280×720.

Stream to Field59

After you’ve configured the OBS settings to the required specs, you can begin streaming by clicking the Start Streaming button. This will send the stream to Field59’s live cloud. The stream will appear in the player for any active Live Events (or Live Channels if the channel player contains an active Live Event) that you have configured in the Field59 video platform to use your stream.
