Like previous Phantom cameras, the Flex4K records
Vision Research’s proprietary Cine Raw format. These
files are captured in 12-bit and efficiently saved to the
CineMag IV in a 10-bit ‘packed’ format. The Cine Raw
files are compatible with many of the industry’s top editing
and post production software packages, or they can be
converted to a variety of formats using software provided
with the camera.
As an alternative to Cine Raw, the Flex4K offers a high-
quality, compressed recording format. Choose to capture
files directly in Apple ProRes 422 HQ to the CineMag IV.
This increases record duration, decreases file size, and
simplifies the process straight out of the camera. Note
that when working with ProRes, there are limits to the
resolution (full 4K or 2K only).
A third workflow option is recording the 3G-SDI video
playback with a video-based field recorder. These devices
are easy to find, easy to use, and take advantage of the
camera’s in-camera video scaling for high-quality video
via two 3G HD-SDI outputs.
The Flex4K allows various configurations for monitoring
the image via the camera’s four total HD-SDI outputs,
and one return. Each output is customizable for monitoring
with frame guides, or as a clean output for use with field
recorders. The outputs can also be switched from
displaying standard gamma to a pre-set Log curve.
All HD-SDI outputs support video scaling for a sharp
1080p output of the camera’s full sensor. Two of the 3G
HD-SDI outputs can also be combined for a 4:2:2 ultra-HD
signal, which will allow the full resolution to be viewed on
4K production monitors.
The viewfinder and monitor feeds can be set to always
show a live feed, so the DP can follow the action and
frame up the next shot while the last shot is still being
saved or reviewed from the other outputs. Zoom (focus
assist) and threshold (exposure assist) functions are
also available.
