Setting up a Luma Key overlay with PowerPoint
The HS-600 has 8 inputs. Inputs 7 & 8 are DVI and these can be used to connect a DVI-D cable from a computer.
The computer graphics card will need 2 output connectors, one for the PC monitor and one DVI connection to go to
input 7 or 8 on the HS-600.
The PC will need to have
Microsoft Office
installed in order for
PowerPoint
to be used. If all the settings are correct
on the mixer and the PC then we can attempt to use this computer display output to create a simple text overlay
using the HS-600
’s Luma Key function.
1. Connect a DVI-D cable between the HS-600 input 8
and the spare DVI port on the PC’s graphics card.
2. Turn on the HS-600 and then the PC.
3. Create a
PowerPoint
presentation with White text on a Black background. You may want to create your
own
Slide Master
within
PowerPoint
.
Use the PowerPoint Help function for advice on how to do this.
4. Select CH8 of the HS-600 so the PC output is shown in the Multi-Image Preview window. Can you see the
PC output in the CH8 or PREVIEW PST_SUB window?
5. If you cannot see the computer output then extend
the PC’s desktop within Windows to monitor 2 as below.
6. PC screen size for monitor 2 should match 1280x1024 or 1024x768.
7. If HS-600 input 8 is just a blue screen (blue desktop background only), then try using the PC mouse pointer
to drag a window or a desktop icon across and onto the HS-600 input 8 window.
8. OK, so you should now have the Monitor 2 PC display running into input 8 on the HS-600.
9. Open up
Powerpoint
on the PC and use
Set Up Show
so that the presentations play back on Monitor 2 (the
HS-600) and the presente
r’s output is sent to Monitor 1 (the PC’s own monitor).
10. Ensure CH8 is selected on the HS-600 Luma Key Settings menu and a different video input is chosen on
the Main Source row of buttons.
11. Press the LUMA KEY PVW button in the SPECIAL EFFECTS area of the HS-600 keyboard.
12. Now you should see the presentation playing back in the PREVIEW PST_SUB window. We can now
attempt to key out the Black parts of the Presentation using the
LUMA KEY SETTING
in the HS-600
’s
System Configuration menu whilst the
LUMA PVW
button is also ON.
13. Once you have the right LUMA SETTING or overlay effect in the PREVIEW window you can then press
LUMA
PGM
key to toggle the overlay effect ON or OFF the main PROGRAM output.
