* Blackmagic RAW is available on URSA Mini Pro 4.6K and URSA Mini Pro 4.6K G2 only.

Constant quality settings for Q0 and Q5 will display varying record time remaining durations.

The estimated duration for Q0 is similar to constant bitrate 3:1, and Q5 will display a similar

duration to 12:1, however, as the estimated duration updates every 10 seconds while recording,

the best way to gauge how much recording time you have is to record for 20 seconds and

monitor the duration in the media area of the touchscreen display.

Data Rate Tables for URSA Mini Pro 12K

Blackmagic URSA Mini Pro 12K allows you to capture images in such a wide variety of

resolutions and frame rates that it is important to understand the implications on the data rate

so you can choose the best format and media for your project. Blackmagic Design has

thoroughly tested a wide range of CFast cards, SD UHS-II cards and USB-C drives to determine

achievable framerates and Blackmagic RAW compression ratios. For more information, see the

'Storage Media' section. Generally, CFast Cards for URSA Mini Pro 12K can sustain a data rate of

around 400 MB/s. These approximate figures should give you a good starting point for what

rates and resolutions you will be able to achieve.

As URSA Mini Pro 12K can record at extremely high data rates, you may wish to double the

bitrate your media is normally capable of by striping the recording across two cards. To do this,

insert a pair of CFast or SD Cards and switch on the 'record RAW on 2 cards' option in the

'record' menu. Since this relies on striping across both cards sequentially, the data rate of the

slowest card will be the limiting factor, so you are advised to use two cards of the same or

similar spec. You can also stripe between a CFast card in storage slot 1 and a USB-C disk in

storage slot 2. When you use the 'Record RAW on 2 Cards' option, the speed limit is twice the

data rate of the slowest card in the striped array. For more information, see the 'Record RAW on

2 Cards' section.

Blackmagic RAW constant bitrate options are designed to give you predictable file sizes and

data rates. When you are shooting a highly detailed scene or fast motion, a constant bitrate

option compresses the image with a constant maximum to make sure the bitrate is kept at or

under the level specified at all times. This makes it easy to understand exactly what speeds

your media will need to sustain and will also give you a good estimation of how long you can

shoot with your media.
