The Blackmagic Design Duplicator 4K is a powerful tool designed for immediate content distribution, particularly during live events. Its core feature is the ability to record UHD 4K video onto 25 SD cards simultaneously via 12G-SDI or optical video inputs. This makes it a highly efficient option for video producers looking to distribute footage to multiple users directly after an event, whether it’s a concert, seminar, or sports broadcast.

Thanks to its real-time H.265 encoding, the Duplicator 4K ensures that even high-resolution content is compressed into manageable file sizes without sacrificing quality. This encoding standard allows for compact video files, which can be easily played on a wide range of devices. Additionally, the Duplicator 4K supports H.264 encoding, providing flexibility for playback on older devices that may not support H.265.

This unit is designed to handle both live duplication and long-form recording. In the latter case, it can switch SD cards seamlessly, enabling continuous recording, ideal for situations such as security surveillance or lengthy events. Its Append Record feature allows you to combine multiple segments of an event into a single file, simplifying playback for end users.

The compact 1RU rack unit design, along with its lightweight and durable build, ensures it can be easily transported to different venues. With a front-panel LCD display, professional users can monitor real-time status and quickly format SD cards or manage recordings. Connections like RS-422 and Ethernet provide remote control options, allowing it to scale for larger projects by daisy-chaining multiple units.

The Blackmagic Duplicator 4K offers ease of use, particularly for solo operations, as it can automatically start recording once a camera begins, responding to SDI start/stop commands from the camera. This makes it perfect for events where the operator needs to manage both the camera and recording simultaneously. Additionally, the SD cards are reusable, making them a cost-effective media choice for repeated use across multiple events​.
