Phantom Flex4K Manual
An AES/EBU signal can be fed into the AES input on the
MiniBob or Sync/Capture cable that came with the original
Flex4K purchase. Audio works at sync-sound frame rates
and above. Analog audio must be converted to digital
AES/EBU using a digitizer, such as the Sound Devices
MixPre-D.
Audio is enabled with the audio menu on the camera
body, or using PCC, and levels are provided on the camera
menu by scrolling right with the select knob. When
enabled, audio gets recorded as a separate file with each
cine, in both RAM and CineMag. The files are downloaded
alongside the Cine file from PCC as
uncompressed
.wav files
which can be matched with the video in post
processing.
The wav files are 48KHz at up to 24-bit, and the camera
supports re-sampling of other frequencies. Audio can be
monitored from the camera live using the headphone jack
on the camera body or more accurately with the AES out
via the Aux2 port on the Minibob. At sync sound frame
rates (matching with video rates) the camera will play
back the audio from the camera RAM. When not matched
the camera will not provide audio playback. Audio play-
back is not supported from the CineMag or over video at
this time.
Yes the Flex4K supports anamorphic lenses by offering a
de-squeeze function for the SDI outputs. For 2.0x lenses,
a recommended resolution is 2752 x 2304. From the
‘Video Settings’ menu, select Anamorphic 1.33x or 2.0x
depending on the type of lenses. The de-squeeze does not
work for interlaced video systems.
At the time of this writing anamorphic Raw .cine files may
have to be cropped and/or desqueezed in post production.
The ‘Lens’ port is a standard 12-pin Hirose used for
common ENG style broadcast lenses. The camera can
power the lens, and accept a trigger signal from the
lens. The lens controls for focus, iris and tally will be
passed through the camera protocol with the intention of
manipulating the lens from a separate device. There is no
in-camera or software interface for ENG lens control.
