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 and write speeds.
Some cards can record sustained RAW video, and some are suited to compressed recording
using ProRes and compressed RAW formats. The tables below identify the CFast cards
recommended for use when shooting with Blackmagic URSA Broadcast.

NOTE
Only the 'D-series' of Sandisk CFast 2.0 cards have been certified for use with
Blackmagic URSA Broadcast. These cards can be identified by a large ‘D’ printed on
the back of the card in the lower left corner, and we have also listed the model
numbers to make them easier to identify. This model number varies slightly from region
to region, with the 'x' in the model number changing in different markets. For example,
an 'A' in the United States and a 'G' in the Asia Pacific and Europe region.
