Preparing Media for Recording

You can format your CFast cards, SD cards or SSDs using the ‘format card’ feature on

URSAMini’s storage and formatting screen, or via a Mac or Windows computer. We recommend

formatting storage media using URSA Mini for best performance.

HFS+ is also known as Mac OS X extended and is the recommended format as it supports

'journaling'. Data on journaled media is more likely to be recovered in the rare event that your

storage media becomes corrupted. HFS+ is natively supported by Mac OS. exFAT is supported

natively by Mac OS and Windows without needing to purchase any additional software.

However, exFAT does not support journaling.

1 Tap either storage indicator at the bottom of the LCD touchscreen to enter the

storage manager.

2 Tap 'Format Card 1' or 'Format Card 2' to format the CFast card in slot 1 or 2, respectively.

Important Notes About SSD Speed

Some models of SSD can’t save video data at the speed the manufacturer claims.

Thisis due to the disk using hidden data compression to attain higher write speeds.

This data compression can only save data at the manufacturer’s claimed speed when

storing data such as blank data or simple files. Video data includes video noise and

pixels which are more random so compression will not help, therefore revealing the true

speed of the disk.

Some SSDs can have up to 50% lower write speed than the manufacturer’s claimed

speed. Soeven though the disk specifications claim an SSD has speeds fast enough to

handle video, in reality the disk isn’t fast enough when used to store video data for real

time capture.

Use Blackmagic Disk Speed Test to accurately measure whether your SSD will be able

to handle high data rate video capture and playback. Blackmagic Disk Speed Test uses

data to simulate the storage of video so you get results similar to what you’ll see when

capturing video to a disk. During Blackmagic testing, we have found newer, larger

models of SSD and larger capacity SSDs are generally faster.

NOTE Before formatting your media, it's important to make sure the media storage

switch has been set correctly to either SD card or CFast card. Always check the

settings carefully before formatting.
