Review: Teradek VidiU Live Encoder
March 07 15:34 2015 Print This Article

Ah CES, it feels like yesterday! One product that got a lot of people talking at the show was my use of the LiveStream Broadcaster and the Teradek VidiU broadcaster. Both products are made by Teradek, but I found that the Teradek VidiU was way better in performance as you can charge the internal batteries and there isn’t a need to constantly be replacing AA batteries as you need to do with the Livestream Broadcaster.

As long as you have an HDMI out port on your DSLR, you are able to live stream content to many streaming services using the Teradek VidiU such as YouTube Live, LiveStream, UStream. You also have the ability to stream to a Wowza server or a custom CDN. The Teradek VidiU is extremely powerful.

What’s in the Box

• AC Power Supply
• Hot Shoe Adapter with Thumbscrew
• Ethernet Cable
• Male-to-Mini HDMI Cable
• Quick Start Guide
• 1-Year Warranty

Live Streaming Without a PC

The Teradek VidiU gives you 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.

Ustream, YouTube Live & Livestream Integration

VidiU is integrated with the Ustream, YouTube Live and new Livestream platforms, which makes streaming to your channel as easy as logging into your account.

Broadcast to any Streaming Platform

Choose the CDN that is right for you. VidiU allows you to stream your live video content to a Wowza server or the platform of your choice at any time.

Go Live Anywhere Cable-Free

VidiU streams over dual band WiFi, Ethernet, or via a single 3G/4G USB modem. For events that require you to be completely wireless, VidiU’s rechargeable Li-Ion battery lets you roam cable-free for up to 60 minutes.

Stream to Android and iOS Devices

VidiU offers a free application for iOS and Android that allows you to monitor your live broadcast in real time. Since VidiU acts as its own dual band Access Point, you can choose to connect your tablet* directly to the device or to your local network.

*Android app is optimized for 7″ tablets

Full HD Video

Connect your HDMI video source to VidiU and stream at resolutions up to 1080p (1080i, 720p, and SD 480p also supported). VidiU encodes video in real-time using H.264 compression and AAC audio at up to 5Mbps. Embedded HDMI audio, headphone output, and a mic/line input are supported.
