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.
