master mode (to generate a genlock signal).
25 Setup the genlock crosslock mode. When disabled the camera will expect a tri-
level sync signal which matches the video mode (see point 15). For 4K / UHD
video modes this means the matching 2K / FHD video mode (e.g. 1080p30 for
21060p30), since there is no 4K genlock standard.
Crosslocking is possible in three different modes:
• Pal Black & Burst
• NTSC Black & Burst
• Other HD Mode
Pal and NTSC B&B are self-explanatory. In “Other HD Mode” you can select the
tri-level sync signal to which the camera shall lock (see point 26).
26 Setup genlock crosslock video mode. This combo-box is only enabled if
crosslocking is set to “Other HD Mode) (see point 25). You can select the tri-level
sync signal to which the camera shall lock.
25 Set the vertical genlock offset in lines.
26 Set the horizontal genlock offset in pixels.
27 Enable or disable genlock termination.
28 Field to enter the timecode.
29 Apply the currently entered timecode.
30 Get the current timecode of the device.
31 Hold the timecode. When enabled the device will stop incrementing the timdecode
on the SDI output. The internal counter will keep running, so if you resume, the
timecode will jump to the current value. This can be used to trigger external flash
recorders.
Note: How to setup the lens shading correction:
1. Point the camera at a homogeneous light source.
2. Connect the camera to a wave monitor and select a line in the middle of the image,
depending on the lens you use, you should see a decrease in luminescence
towards the edges of the image.
3. Enable lens shading correction, start with the Cosine
4
Compensation, Offset and
Slope set to 0.
4. Now turn up the Cosine
4
Compensation, this should correct the lens shading in the
middle area of the image, the edges will probably still be not ideally illuminated.
Make sure to not overcompensate, this will create a wavelike appearance of the
luminescence on the monitor.
5. Set the Offset to 0.5 and set to Slope to a high value like 1.5, you should now
clearly see where the compensation starts. Now adjust the Slope until you hit the
point where the luminescence starts decreasing. Finally decrease the Slope until
the result is not overcompensated anymore.
6. Make fine adjustments until you are satisfied with the result.
