Quick answer
Choose the Teradek Prism Flex Mk II if you need a portable, all-in-one encoder that can mount on a camera or sit between your mixer and switcher. Pick the Teradek Prism 877 (SDI) if you're building a rack-mount encoder/decoder system and need SDI I/O in a card form factor.
Portability vs rack integration
The Prism Flex Mk II is a compact, aluminum-bodied encoder designed for on-the-go use. It can be placed on a table, attached to a camera, or positioned between a video mixer and audio mixer, making it a flexible choice for field production or small studios.
The Prism 877 (SDI), in contrast, is a professional card that installs into a Prism Rack chassis. It's built for environments where multiple channels need to be housed in a central location, such as broadcast trucks, control rooms, or event production racks. This trade-off is about where you need the encoding to happen: at the camera or in the rack.
Understanding the input/output difference
Both units support DCI 4K60 encoding, but the Prism 877 (SDI) is explicitly a card that handles both encoding and decoding. That dual role makes it a more versatile building block in a rack system, where you might need to decode feeds as well as encode them.
The Flex Mk II is an encoder, so its primary job is to convert video into a stream. If your workflow requires decoding alongside encoding, the 877's card design may be a more efficient use of rack space.
Trade-offs at a glance
- Form factor: Flex Mk II: portable, all-in-one unit. Prism 877: rack card requiring a chassis. Assess whether your setup is mobile or fixed before choosing.
- Encode vs decode: Flex Mk II: encoder only. Prism 877: both encoder and decoder. If you need decode capability, the 877 is the only option here.
- Mounting flexibility: Flex Mk II: can be tabletop, camera-mounted, or placed between mixer and switcher. Prism 877: designed for rack installation. Consider where your signal chain physically lives.
