VariCam LT Ready for Live White Paper
3. Image Enhancement Parameters and ROP Supported Items
3.1. Supported parameters for Each Main Color Settings
The following shading modes have been added to VariCam LT Version 6.0 and later to facilitate use in
multi-camera systems.
(Note: HLG is supported from Version 8.0.)
(1) Main Color: V-Log, Grading Sel: Shading
While still using the V-Log signal for recording, outputs such as Gain and Pedestal can be controlled with the ROP.
Since there are no major image enhancement changes, it is recommended to use this together with 3D LUT
for enhancement. This mode can be useful when Camera outputs are live, and recorded images are graded in
postproduction.
(2) Main Color: Shading, Gamma Sel: V-Log
Controllable parameters are almost the same as (1), but ROP control also applies to the recorded images, except for
3D LUT. Applying 3D LUT during post-processing will reproduce the same images as the output.
This mode can be useful when images are enhanced to a certain degree on set, and LUT and other tweaks are added
in postproduction.
(3) Main Color: Shading, Gamma Sel: BC Gamma/HLG
This mode enables as almost all VariCam LT image enhancement settings as possible to be controlled by the ROP.
3D LUT cannot be used. This mode is recommended for situations where there is no postproduction and the entire
shot will be composed on set.
When selecting BC Gamma, it is also possible to adjust the gamma, enabling more flexibility of adjustment than the scene 1-5
preset gammas.
(4) Processed RAW Mode
Processed RAW output superimposes image-enhancement processes for live operaSon. The whole system works as 4K
when the camera is connected to VariCam 4K RAW supported devices. Processed RAW can be selected when Main Color is
set to any color mode other than V-Log mode.
According to Main Color, Grading SEL, Gamma SEL settings include the above mode, VariCam LT can be used to
control the following items via the ROP.
