The maximum sensor resolution is 2560x1600.The record resolution is selec-
table for the given application, which in turn expands options on record time
and frame rates.The camera uses a single CMOS sensor and a 35mm film for-
mat PL lens mount. (Other available lens mounts include Nikon & B4 using an
adapter) Common resolution choices are 1920x1080 (aka 1080p) and 1280x720
(720p). Other resolutions are also available for Digital Cinema or broadcast
use.The resolution is selectable in eight pixel increments for custom framing
options.
The Flex can record RAW file at 2560x1440 and then output via HD-SDI at
1920x1080 without cropping the image area.This oversampling technique re-
sults in higher quality video.
The full size of the sensor (2560x1600) is 25.6mm x 16mm, which is slightly
larger than 3-perf Super35 film. When shooting at 2560x1440 (16:9 ratio) &
using the oversampling method on the Flex, the sensor size is 25.6mm x
14.4mm. At 1920x1080 without using oversampling, the image area is 19.2mm
x 10.8mm. In 1280x720, the image area used is 12.8mm x 7.2mm.
Frame rates are dependent on the choice of resolution & bit depth. At full res-
olution (2560x1600) in SQ mode, the max frame rate is 1455fps. In HQ mode,
it is 725fps. At 1920x1080 in SQ mode, it is 2570fps. In HQ mode, it is 1275fps.
The maximum frame rate when recording at 256x8 pixels, is a whopping
280,000fps! For a detailed list of all available frame rates, go to: (insert link)
HQ mode is a new proprietary recording mode introduced by the Phantom
Flex that greatly reduces the need for black balancing the camera, as well
increasing the signal to noise ratio of the camera. It involves reading extra

Check the video output format.The Sony viewfinder will only work with 1080i
& 1080psf, not with any 720p formats.
The SDI-1 BNC connector will only output a clean signal, meaning it will not
overlay any menu features on top of the video image. SDI-2 has the option to
switch the menu characters on or off.
The camera could be set to R/S mode (direct recording to magazine).The Flex
has the option to capture in HQ mode, which can also reduce the maximum
frame rate.
There is an image from the
SDI output but no image
in the viewfinder.
I cannot see any on screen display
from the SDI-1 output, even when I
switch on the OSD.
I cannot set the maximum frame
rate I’d expect to have at this reso-
lution.
