16 Enable 4K to 2K downscaler and optional interlacer for the first SDI output. This
option is only available for 4K cameras, see the cameras reference manual for
more details.
17 Set the mode of the second SDI output. In mirror mode the image is identical to
the first output, in RAW-10 and RAW-12 modes a custom raw image will be output.
Set it to “SDI-2 LUT” to use a custom de-gamma LUT for the second output. To
configure the LUT of the second output additionally you have to switch to SDI-2
config in the Toolbar (see chapter 3.1, point 5 and 6 and chapter 4.9 for more
details).
18 Enable 4K to 2K downscaler and optional interlacer for the second SDI output.
This option is only available for 4K cameras, see the cameras reference manual
for more details.
19 Set the flip mode to mirror the image vertically, horizontally or both (rotate 180°).
20 Enable or disable Audio and setup the audio gain. When enabled the audio signal
of the device internal microphone is embedded into the SDI output signal.
You can change the audio gain via the spin box to the right of the enable button.
The default gain is 1.0, to for example double the volume set a value of 2.0, to half
it set a value of 0.5.
21 Enable HDR / LOG mode. In LOG mode the gamma curve of all outputs is fixed to
either HLG, PQ or S-Log3. This generates a “flat” output image which preserves
more details in the highlights.
• In HLG LOG mode the gain range is adjusted (minimum ISO is doubled) to
match the LOG curve.
• In PQ LOG mode you can use the “PQ Display brightness” setting to adjust
the gamma curve to your display (see point 22).
• In S-Log3 LOG mode you can use the “S-Log3 Master Gain” setting to
adjust the gamma curve to your needs (see point 22). In this mode the SDI
output range is fixed to “Extended Range”, it can not be changed in the
Output Tab (see chapter 4.12).
Please note that in either LOG mode the Lookup Table Tab (see chapter 4.9) is
deactivated.
22 Depending on the LOG mode (see point 21) you can either setup the PQ display
brightness, or the S-Log 3 master gain:
• Setup the PQ display brightness from 100 to 10000 cd/m
2
. At 10000 cd/m
2
the image contains all highlights, but most display will not be able to display
them since they do not achieve the required brightness. At the default value
of 1000 cd/m
2
most HDR displays should be able to display the image
without clipping. Only visible if LOG mode is set to PQ (see point 21 above).
• Setup the S-Log3 master gain from -6 to +12 dB. This feature works
similarly to the “Master Gain” setting of Sony Broadcast cameras. At a
master gain of 10 dB you will use the full SDI code range.
23 Switch between Rec.709 and Rec.2020 color space. This will also change the
color conversion matrix (see chapter 4.12)
24 Enable genlock in slave mode (when connecting an external sync source) or
