Two dedicated outputs are available to accomodate both
component and HD-SDI compatible viewfinders.
Vision Research is offering a full HD OLED viewfinder
as the recommended viewfinder for the Flex4K camera
system. The viewfinder is manufactured by Astro Design
and includes a dedicated mounting bracket and necessary
cables.
The bracket plate mounts to the top of the camera, in a
variety of positions:

The three main outputs are separated as 1x monitor
(MON) output, and 2x recording (REC) outputs. The 2x REC
outputs can be configured as individual 1080p outputs
or used together to provide a dual-link 4K video output.
All outputs must be on the same video system, and the
4K/2160p signal is determined by the settings of the other
outputs / and vice versa.
The Component and HD-SDI viewfinder outputs (VF) at
the front always work together, and provide the same
image, with the same overlays, zoom modes, etc. The
MON output can also mirror the VF output.
All Flex4K video outputs can be switched between Rec709
and a factory installed log curve. By exposing in the
Phantom log mode, you get a 1.8 stop exposure index (EI)
boost which takes advantage of the sensor’s low noise
floor and maximizes the dynamic range.
When in Log mode, the camera’s gamma, gain and other
image tools settings no longer apply.
The return signal can be used to display the SDI feed from
another source, as well as a genlock and sync source. In
order for this to be active, the incoming signal must match
the bit rate and video system as the camera, and the
frequency should lock automatically.
Once frequency lock is achieved the camera can switch
the Viewfinder outputs to display the return signal.
Two cameras can be easily synchronized with a genlock
source, or by taking the video output from one camera
and linking it to the return feed of the second camera.
Ensure the video modes of both cameras match perfectly.
