Phantom Flex4K Manual
Optionally, the user can select common white balance
settings of 3200, 4300 and 5600, or manually adjust
the Color Temperature (Kelvin) for the red and blue
components of white balance, and Color Compensation
(CC) for the magenta and green components of the white
balance.
Exposure Index
EI (Exposure Index) is a reference value for the
apparent light sensitivity determined by the current
image processing settings. The available presets range
from an EI of 250 through 800.
The EI value can change based on the gamma, toe,
gain, ped, tone curve, and other settings of the camera.
By adjusting the EI with one of these presets, most image
settings will go back to their default value.
When the camera’s video output is set to ‘Log’ mode,
the EI can not be adjusted, and must be used as a
reference only.
Mode
Mode specifies the operational ‘Mode’ of the camera in
relation to CineMag recording
•
Loop Mode - image data is recorded to camera
internal memory (RAM buffer / circular buffer) prior
to saving it to an attached Phantom CineMag IV or
external hard drive.
•
R/S (Run/Stop) Mode - images are recorded
directly into an attached CineMag IV. The maximum
possible frame rate to a 2TB CineMag IV is limited
to 120 fps at full resolution in R/S mode.
A long press of the ‘Mode’ button switches the camera
between Loop and R/S modes.
Trigger Point (only active in ‘Loop’ mode) specifies the
percentage of ‘Post Trigger’ frames recorded AFTER the
camera has been triggered.
A long press of the control knob allows you to dial in
the post trigger in 10% increments. To set it, the camera
must be in ‘Loop’ mode, and the home menu must be
displayed.
When the camera is capturing, it is continuously rolling
into its circular RAM buffer, which is represented by the
‘Timeline’. If you have approximately 5 seconds of record
time, a trigger point in the middle will keep the previous
2.5 seconds and when triggered will record for an
additional 2.5 seconds until the RAM is full.
In R/S mode there is no trigger point, and the time line
represents the space in the CineMag.
