Phantom Flex4K Manual
sensor resolutions
The Flex4K sensor natively operates in either 4K or 2K
mode. Any output resolution that is not 4096 or 2048
pixels wide is considered non-native, and as such the
software needs to crop or re-sample when set to different
resolutions.
To simplify things, only specific resolutions (listed at left)
are available from the camera menu. The choices are a
variety of common resolutions and aspect ratios.
The resolution menu will tell you if it’s operating in
4K mode or 2K mode, and if the camera is cropping
or re-sampling to achieve the desired output resolu-
tion. 2752 x 2304 is the best choice for recording with
anamorphic (2x) lenses. The resulting footage must be
de-squeezed in post.
The video monitor will still show the full 4K width, and
the cropped resolution will be indicated with a yellow box.
In the case of ‘Scaled’ resolutions, the camera is capturing
a larger resolution with the intended output at a smaller
resolution. For example, a full 4096 x 2304 capture can
be set to output at 1920 x 1080 in order to maintain the
35mm format. In this case, you are still limited to the top
frame rate at the full resolution in which the camera is
capturing.
What is the difference
between ‘Native’, ‘Scaled’,
and ‘Cropped’ resolutions?
The resolution controls in PCC software are somewhat
different, and allow more flexibility in choosing how the
images are captured and output. First, the native resolu-
tion must be selected from the ‘Cine Settings / Resolution’
pull-down, and the output resolution must be set using the
‘Geometry & Overlays’ section of the ‘Image Tools’ menu.
There are a variety of pre-set output resolutions available,
or any value can be typed in and offset with the X & Y
coordinates listed. Cropped or scaled resolutions set on
the camera body will automatically set the ‘Crop &
Resample’ parameters appropriately.
Cine Raw files saved from PCC software will maintain
the full native resolution, with the crop/resample settings
flagged in metadata.
Exporting those files in a format other than Cine Raw
(like .mov or .dpx) will apply the settings, and the resulting
files will be at the intended cropped and/or resampled
output resolution.
Cine Raw files that have been flagged with crop/resample
metadata can still be exported at the full captured
resolution by turning off the Crop & Resample options
in PCC’s Image Tools menu.

The PCC ‘Image Tools /
Crop & Resample’ menu
is also a powerful way to
manipulate saved Cine files
prior to exporting the files
to a different format.
