Inserting a CFast 2.0 card into one of Blackmagic URSA's
two CFast slots.
Blackmagic URSA Mini has two CFast slots for continuous
recording.

Inserting a CFast Card

Blackmagic URSA and URSA Mini use CFast 2.0 cards to record 4K, Ultra HD or HD video.
To insert a CFast card.
Step 1. Open the fold out monitor to access the CFast slots.
Step 2. With the label on the CFast card facing the touchscreen, insert the card until you feel it
lock into place. Push on the CFast card ejector button to eject the card.
Step 3. The status strip will display a moving dot while the camera checks the CFast card and then
it will say 'ready'. Additionally, on URSA, the touchscreen media timeline will display a time
remaining indicator. On URSA Mini, the CFast indicator at the top right of the screen will
show the time remaining on detected cards.

Preparing a CFast Card for Recording

CFast cards must be formatted as either HFS+ or exFAT. HFS+ is also known as Mac OS extended.
It is the recommended format as it supports "journaling". Data on a journaled CFast card is more
likely to be recovered in the rare event that your media card becomes corrupted. HFS+ is natively
supported by Mac OS X.
ExFAT is supported natively by Mac OS X and Windows without needing to purchase any additional
software. However exFAT does not support journaling.

Choosing a CFast 2.0 Card

When working with high data rate video it's important to carefully check the CFast card you would
like to use. This is because CFast 2.0 cards have different read/write speeds. Some cards can record
sustained 4K RAW video, and some are suited to compressed recording up to ProRes 422 HQ or
4K RAW 3:1.
Below is a list of recommended CFast 2.0 cards for recording compressed formats. For supported
frame rates, refer to the Blackmagic Design support center at www.blackmagicdesign.com/support.
