Choosing a Fast SD Card

It's important to use high speed UHS-1 SD cards. These
cards are rated for fast data speeds and support larger
storage sizes.
All UHS-1 SD cards should be fast enough to record
compressed HD video up to 60 frames per second, however
Formatting SD cards using Blackmagic Video Assist
It's very easy to format your SD card using the storage
settings in Blackmagic Video Assist. You can format your
card using HFS+ or exFAT formats.
HFS+ is also known as Mac OS Extended. It is the
recommended format as it supports "journaling". Data on
journaled media is more recoverable and less likely to be
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 which means
data is less protected against the rare event your media
card is corrupted.
To format your SD card:
Step 1.
Swipe your Blackmagic Video Assist's touchscreen left or
right to open the storage settings.
Step 2.
Tap the 'format card' icon at the bottom right of the
touchscreen menu.
Step 3.
Tap the arrows to select your desired HFS+ or exFAT format
type, then tap the 'format card' icon again.
it's worth testing your card's record speed to be sure. You
can do this using Blackmagic Disk Speed Test software
included with your Blackmagic Video Assist. For information
on using Disk Speed Test, refer to 'checking disk speed'
in this section of the manual.
Step 4.
A warning will appear asking you to confirm the format. If
your SD card contains data already recorded, make sure
you back it up before formatting as this action cannot be
undone. Tap 'format card' to continue, or 'cancel' to cancel
the format.
Step 5.
A progress bar shows you the progress of the format.
'Formatting complete' will appear when the format is done.
Step 6.
Tap the 'ok' icon to return to the storage settings.
Blackmagic Video Assist can format your SD cards in HFS+
or exFAT formats using the 'storage' settings. Swipe the
touchscreen left or right to open the 'storage' settings menu.
