MEDIA BEST PRACTICES
This section describes best practices to ensure that your CFast cards continue to provide reliable storage and fast
data rates. Following these best practices may prevent your CFast card from becoming fragmented, which can lead to
data integrity errors.
The only files that should be saved from your computer to your CFast card are Preset files, Firmware Upgrade
files, and LUTs. DO NOT save other files, folders, or applications to your media.
DONOT back up your hard drive to the CFast card. If using a Mac, the system may ask if you want to back up
your files to the CFast card using Time Machine; DONOT use the CFast card as a backup disk.
DO NOT delete clips off of your CFast card using a computer. Delete clips only by formatting your CFast card in-
camera. For more information about formatting your CFast card, refer to Secure Format.
DO NOT format your CFast card using a computer, unless the CFast card cannot mount to the camera. For more
information, refer to Secure Format.
When ejecting the CFast card from a computer, ensure that the icon has completely disappeared from the Finder
window (Mac) or from Windows Explorer (Windows) before removing the CFast card. Sometimes, the pop-up
saying that the CFast card has ejected displays too early.
When the reader has a write-protect switch (such as the RED CFast 2.0 Reader), it is recommended that you set the
card reader to write-protect when uploading clips to prevent connected devices from adding any unwanted data to
your CFast 2.0 card.
INDEXING ON A MAC
NOTE: You can use the RED CFast 2.0 card reader with Write-Protect to prevent the Mac OS from indexing your
CFast 2.0 card (refer to RED CFast 2.0 Reader).
Most newer versions of the Mac OS automatically index all external drives when you connect them. This includes
when you connect CFast cards.
Indexing makes the connection process take longer. While the CFast card connects to the Mac, DONOT remove the
card. Indexing writes hidden files to the CFast card. When you insert an indexed CFast card in the camera, it can take
the camera a while to recognize the hidden files and connect to the CFast card. While waiting for the CFast card to
connect, DONOT remove the CFast card or turn off the camera. After the camera successfully connects to the CFast
card, perform a secure format to remove the hidden files. For more information, refer to Secure Format.
EXPOSURE
The camera offers multiple tools to determine the current image exposure levels and provides the tools to adjust the
exposure to the desired levels.
When using the R3D file format, you can correct color temperature and ISO settings at any time. The aperture and
exposure time however, are two of the parameters that you cannot corrected later in R3D files.
NOTE: ProRes file format burns in ISO and White Balance, and does not allow you to adjust these settings post-
recording like you can with the R3D format.
While the correct exposure is always an artistic decision, there are best practices for capturing the most dynamic
range while also allowing post production to preserve the intended image information.
The goal is to reduce clipping in the bright and dark parts of the image as much as possible. Otherwise the sensor
information is lost in the overexposed and underexposed areas.
The primary tool for determining the exposure levels is the histogram. It shows the exact luminance levels of the red,
green, and blue pixels after you apply the ISO and White Balance settings. Monitors have their own color gamuts and
brightness levels which makes the monitor less than optimal for determining the camera's exposure levels.
This camera includes a full Histogram and a simple RGB raw pixel exposure meter, which allows you to determine
proper exposure regardless of the set ISO or camera look (for more information refer to LCD Touchscreen).
