Blackmagic Design URSA Mini 4K EF-Mount Overview
Now in a smaller, more handheld-friendly form factor, the URSA Mini 4K Digital Cinema Camera from Blackmagic Design can record cinematic images with its Super-35mm 4K, global-shutter sensor with 12 stops of dynamic range. The ergonomic body design is balanced and can be used for many different styles of filmmaking. The EF-Mount is compatible with a plethora of popular lenses, opening different aesthetic options. A rosette on the side of the camera accepts the included side handle, which can control Start/Stop via a LANC connection.
To produce cinematic images, the URSA Mini can record raw sensor data in the CinemaDNG format onto CFast 2.0 memory cards at up to 60 fps. The raw files preserve the full dynamic range and color tonality output from the sensor, so you can have greater control over the look in post-production. However, data-heavy uncompressed raw files aren’t always easy to deal with on set, so in addition to uncompressed raw recording, the 4K URSA Mini provides compressed raw recording at a 3:1 compression ratio to save space while retaining post-production flexibility.
The URSA Mini also records UHD 4K (3840 x 2160) and 1080p video using ready-to-edit ProRes files in many different flavors within the 444 and 422 chroma subsampling variations, depending on your workflow. Starting at the high end, UHD footage can be recorded in ProRes 444 XQ at a rate of 312.5 MB/s all the way down to 1080p in a ProRes 422 Proxy file coming in at a relatively paltry 5.6 MB/s data rate. Since the camera accepts dual CFast cards, you can record for long periods of time by having the camera switch cards when one is full.
Power for the URSA Mini can be supplied via a 4-pin XLR jack at the rear of the camera. With an optional plate, the URSA will accept professional V-Mount or Gold Mount batteries on the back. Once connected to power, the URSA can even distribute power through a second 4-pin XLR jack.
Compact Handheld Design
Sizing down the familiar URSA shape enables the URSA Mini to fit into feature and indie film, broadcast TV, commercial, documentary, and music video workflows with crews of any size. Using the optional shoulder mount with a built-in quick release plate, the URSA Mini can go from handheld to shoulder to tripod in a matter of seconds. Despite its size, the URSA Mini still fits essential I/O for professional workflows.
The body is made from magnesium alloys to keep the URSA Mini lightweight at 5 lb. To make the camera more acceptable for handheld usage, a side handle is included. With the optional shoulder mount, the handle can be extended off the side of the camera to be used in a doc-style configuration.
