Review: The VidiU Live Streaming Device From Teradek

By Heath McKnight (doddleNEWS)

Teradek’s VidiU is a small device that allows you to do live stream broadcasts, in high definition, with only your camera and an internet connection, either 3G/4G, WiFi or wired. And it works great, all without needing a computer, and it’s easy to use.

The VidiU is small and light, and extremely portable. The instructions are simple and easy-to-follow. I’ve used other, similar devices, and it seems like you need an advanced degree to get it to work. It’s as simple as plugging in your camera via HDMI, setting up your internet connection via WiFi, Ethernet or a 3G/4G USB modem, connect to your live stream page and you’re ready to go. Also, the VidiU has a built-in battery, so once it’s charged, you’re even more portable, especially with a 3G/4G connection.

That’s exactly what we did with the VidiU, and we were broadcasting live within 10 minutes of first pulling the live stream device from the box and connecting it to our UStream account. I was anticipating a level of difficulty, but Teradek made it easy. The OLED screen is easy to navigate, and where you log into your live streaming account, connect to the internet and more.

You can stream live to UStream, Livestream, Dacast,, Brightcove and others. Since it’s small and very portable, as long as you have a WiFi, wired or 3G/4G internet connection, you’ll be able to go live anywhere. In fact, there is excellent built-in support for UStream and Livestream, and uses RTMP as its transport protocol.

For our test, we used two cameras, a small Canon VIXIA HFM31 handheld consumer camera, and a Sony PMW-EX1R. Again, it was easy to connect either camera to the Teradek VidiU device and within a short time, we were doing live stream broadcast tests with both cameras, in full HD 1080p.

We had no problems with playback on our computers, the video and sound was smooth. The VidiU uses H.264 for compression with a bit rate between 250 Kbps up to 5 Mbps. Video formats include 1080p at 23.98/24/25/29.97/30 fps (frames per second); 1080i at 50/59.94/60 fps; 720p at 50/59.94/60 fps; 576p/i; and 480p/i. Other than ultra HD (UHD), like 2K and 4K, all the popular video formats are supported. The audio is compressed via AAC-LC.

The VidiU interface and I/O ports include an on/off switch, a start/stop button (to control when you’re live streaming), a menu button, a headphone jack (1/8-inch), a USB port for a 3G/4G modem, an HDMI port (supports up to 1080p), a mic/line input, an Ethernet port (supports 10/100BASE-T) and a port for power. There’s built-in WiFi in the VidiU live stream device, which is dual band MIMO, 802.11 a/b/g/n.

There’s a free VidiU app for your iPhone that allows you to watch your live stream as a second monitor, to make sure everything is going smooth. This is especially useful if you’re out in the field. It gives you the stats of the device and your page.


If you’re looking for an easy-to-use live streaming device, you can’t do much better than the Teradek VidiU. We were broadcasting smooth 1080p video and clean audio over our UStream account within minutes of pulling it out of the box. It’s perfect for your own live shows, whether at your home base or remotely. doddleNEWS will be able to use this to broadcast from trade shows. Find out more at Teradek’s website.
