In the diagram, you will see that we recommend a minimum of four lights and we keep the
subject more than 1m away from the backdrop. It is always easier to get more even
lighting if the subject is farther away from the backdrop (no shadows). The foreground
lighting on the subject will also vary according to the effect that you are looking for.
After the studio set up is complete, connect the camera shooting the speaker on a green
backdrop to the SDI Input 1 at the rear of the switcher. To configure the settings that will be
used for chroma keying, press the
MENU button on your HS-3200 control panel to open the
OSD menu on the monitor. Follow the steps below to configure the chroma key settings.
1. Open the Keyer sub menu and select Key 1.
Keyer Keyer Key 1
Keyer Ctrl Chroma Self Opac 100%
Lift 0% Gain 1.0 Invert Off
Key Source Input 1 Fill Black
Mask Left 0% Right 0%
Top 0% Bot 0%
2. Select “ Chroma ” and “ Self ” under “ Keyer Ctrl ” and then select the camera source under
“ Key Source .” In this example, we have selected Input 1, which corresponds to the SDI Input
1 at the rear of the switcher and therefore the port to which the camera is connected.
3. Adjust the left, right, top and bottom values of “ Mask ” to set the chroma key range
according to green or blue backdrop size.
4. Open Chroma Sub Menu and adjust the corresponding chroma key parameters. Again in
this example, we have selected Input 1, which corresponds to the SDI Input 1 at the rear of
the switcher.
Note : Selection of CK Auto automatically calculates the best Hue & Luma values for the
current Keyer source.
