This article details how to configure the Teradek VidiU encoder to send video streams to the Field59 live stream platform.

The VidiU is a small form factor (3″x4″x1″) encoder that, as Teradek states, gives users “The freedom to broadcast live high definition video directly to the Web without a PC. Whether you’re streaming out of a video switcher or wirelessly from your camera, VidiU allows you to go live when you want, where you want.”

There are some situations in which the VidiU may be more advantageous to use compared to software-based encoders such as Adobe Flash Media Encoder or Open Broadcast Software, or other hardware based encoders, including Field59’s own hardware offering. These include:

    • HDMI output from video camera/source is available, but you do not have a computer with HDMI input where you can run a software encoder.
    • Closed captions are not required
    • Situations where a single camera is needed, but needs to be tucked out of the way, such as a small conference room where a software encoder running on a desktop machine may be too obtrusive.

Here’s what you need to stream using Vidiu:

  1. Video/audio input: VidiU accepts HDMI input. For audio, there is an option to connect an external mic input (1/8″ stereo connector). Video/audio streams to our platform via RTMP.
  2. Internet connection: Connect via Ethernet (wired), wifi, or 3G/4G USB modem. The Vidiu contains a re-chargeable Li-Ion batter that allows the encoder to operate cable-free for up to 60 minutes.
  3. Mobile device (recommended): VidiU has a free mobile application for IOS and Android. Using the app, you can configure and monitor your stream input.


Here’s how to operate the VidiU with Field59.

After you have connected your HDMI cable, Ethernet cable (if using wired), and power cable, turn on the device. It will show a splash screen, then Starting.

Next, when it reads Let’s get you online, the encoder will try establishing a connection to the Internet either by DCHP assigned settings, or by preconfigured network settings. This might take a while depending on network bandwidth and DHCP server settings. Once connected the Encoder will display a confirmation.

Next the encoder verifies it can communicate to the preconfigured live streaming servers.

Once connection to the live streaming servers is verified, the encoder will check for any firmware updates. Field59’s platform works on version 1.4.2.

(NOTE: If a new firmware is found, please check with Field59 support to verify the new firmware is compatible with our live streaming servers, before you install a new version. Push the red Start/Stop button to the left to highlight cancel and then press it again to cancel the firmware update if need be.)

Next, the encoder initializes all settings and checks for video and audio inputs. (For the initial setup, you may have to add stream credentials in the Broadcaster > Platform > Manual Settings area. Please see the section later in this guide for more information.)

Once the encoder is ready to send your live stream to our live streaming servers, the word Ready will appear in the upper right portion of the screen.


Press the red Start/Stop button to begin sending your live stream to our servers. When the encoder is streaming, you will see the word Live in the upper right.


Press the red Start/Stop button again to stop the stream. When the stream is stopped, you will see the word Ready in the upper right.

Using the VidiU app to configure the device


There are apps for both iOS and Android that allow the user to monitor the A/V input and adjust the encoder settings.

After downloading the app, switch your mobile device to the proper network to access the encoder. (See below)

  • If the encoder is not using a wireless Internet connection, switch your mobile device’s wifi to connect to the “vidiu” wireless SSID.
  • If the encoder is using wifi as it’s main connection to the Internet, then make sure your mobile device is on the same wifi network. Video monitoring will be disabled in this type of setup.

After launching the app, It will search for the encoder. Once found, If stream button is red, streaming is occurring; otherwise if green then encoder is ready to start. To start/stop a stream, tap the circular “stream” icon in the middle of the screen.


The main screen has the following information:

  • Live stream status indicators
  • Internet connection indicator
  • Video input and format indicator
  • Power indicator
  • Stream URL and name.
  • Video monitor (if your mobile device is connected to VidiU as WiFi access point).
  • Screen shot button (saves to camera roll)
  • Settings button.

Tap Settings and you will get to a screen with the following options: Broadcast, Video, Audio, Network, System, and Help.



This button contains live streaming server and stream quality settings.

  • Quality > Video provides these options:
    • Full HD: 5 Mbps (only for very high bandwidth connections)
    • HD: 2.5 Mbps (recommended for most streams)
    • High: 1.5 Mbps (for low bandwidth connections)
    • Medium – Custom: not recommended.
    • Suggest Quality will check bandwidth. speed and auto-pick best quality level.
    • Always turn on Adaptive bitrate.


  • Quality > Audio provides options for audio quality: High, Medium, Low, Mobile. High is the only recommended setting.


  • Quality > Frame Rate
    • Full: 30fps (recommended)
    • Half: 15fps
    • Quarter: not recommended


  • Platform: Options for Ustream, Livestream, YouTube, Manual. Field59 stream settings are configured in Manual.
    • URL: streaming URL will be provided by Field59.
    • Stream: the unique name of your stream; will be provided by Field59
    • User: username to log into Field59 streaming servers; provided by Field59
    • Password: provided by Field59
    • Auto Reconnect: if connection should be temporarily lost, the encoder will attempt to reconnect when connection is available. Recommended to set to on.
    • Auto start: If this is enabled, the encoder will automatically start streaming once it powers up.



This button controls widescreen setting. We recommend using the Auto option.



This button contains input source and stero/mono settings:

  • Source: HDMI, Analog, Disabled. In most cases this will be HDMI.
  • Channel: Stereo, mono (left), mono (right). In most cases you will want Stereo.



This button is where the device connection is set up.

  • Network > Wired > Dynamic DHCP: In enabled DHCP setting, the VidiU will attempt to pull network settings from local DHCP server and display them here.


  • Network > Wired > Static: Static settings is where you manually enter all network settings. If you are renting an encoder from Field59 and provided this information prior to shipping, Field59 will fill these fields in for you.


  • Network > Wireless: If your phone is connecting via wireless, there are three options here.
    • Access Point: This runs a local WiFi SSID called “vidiu” that your smartphone, tablet, or wifi enabled device can connect to for VidiU device management.


  • Client: This option is for when a wired connection is not available for the VidiU, or if the wired connection does not has enough bandwidth and only a WiFI connection or hotspot is available.


System and Help

These buttons are not needed to stream with Field59 using the VidiU.
