Prism vs Cube: A Buyer’s Guide
In this buyer’s guide, we’re going to cover everything you need to know about Teradek’s professional-grade encoder and decoder solutions tao decide which is right for you.
Both Prism and Cube enable live video streaming over the internet. They offer point-to-point workflows (encoder-to-decoder), local wireless video monitoring, proxy file uploads for camera-to-cloud workflows, and so much more.
Designed for live production companies, broadcasters, filmmakers, megachurches, and large corporations, Prism and Cube perform in mission-critical scenarios where reliable, color-accurate, and low latency point-to-point streaming is needed.
Let’s unpack each solution to help you decide which device solves your IP video needs
A Brief History of Cube and Prism
A Brief History of Cube and Prism
Cube is Teradek’s longest running line of encoders and decoders. In fact, the first Cube (Cube 100) was an early pioneer for portable box encoders. Before compact devices like the Cube 100 came along, the only other option for hardware encoders and decoders was a large rack unit. The difference?
A typical rack unit is roughly the size of a briefcase.
A Cube 100 is roughly the size of a deck of cards.
This portable device leveled the playing field – allowing anyone to mount a Cube to their camera or camcorder, and live stream their content to the internet from anywhere. As the years progressed, Cube kept upping the processing power – increasing capacity for features like HEVC, SRT, SDI video inputs, and even network bonding for a reliable live streaming connection.
And for those who needed a rack unit solution with multiple encoder and decoder cards? In 2020, Teradek launched Prism Rack Unit – enabling up to 4K HDR video for live broadcasts. Now, the all-new Prism Flex provides the same rock-solid, low latency delivery found in Prism’s powerful rack unit – but in a lightweight, camera-mount, and table-top body.
Now that you’ve got a lay of the land, let’s get to know each solution.

Studio Production: Prism Rack Unit Field Production: Cube 600, Cube 700, Prism Flex
4. What are your bandwidth requirements?
4. What are your bandwidth requirements?
If you have below 5 Mbps of upload, you’ll be better off with an HEVC encoder and get twice the efficiency as AVC.
HEVC: Cube 700, Prism Rack Unit, Prism Flex
(If you have between 5-20 Mbps of upload, HEVC or AVC will do.)
HEVC/AVC: Cube 600, Cube 700, Prism Rack Unit, Prism Flex
(If you have between 20 Mbps up to 85 Mbps of upload, Prism is your solution.)
Max Bitrate of 85 Mbps: Prism Rack Unit, Prism Flex
5. How strong is your internet connection?
5. How strong is your internet connection?
You have a solid Ethernet connection: Cube 600, Cube 700, Prism Rack Unit, Prism Flex
You have a solid WiFi connection: Cube 600, 700, Prism Flex
