5.1 Placing a logo on the video using the lumakey
The ShowCast-100 allows the user to place a logo on the video using the lumakey. First, create a
1920x1080 (16:9) logo against a black or white background on a laptop. Once the logo is created, simply
follow the steps outlined below to insert the logo layer.
Note: If your logo consists mainly of dark colors, choose a white background; if the logo consists
mainly of bright colors, choose a black background.
1. Connect the laptop to the switcher’s one of the HDMI input ports (Inputs 1 to 4).
2. Then on the touch screen interface, press the MENU button to open the OSD menu.
3. Tap the Lumakey sub menu and set the “Lumakey Source” to the input that the laptop is connected
to.
4. If the logo is against a black background, choose Black Mode (choose white if the background is
white).
5. Set the “Cleanup Level” to 10 if the background is in total black.
6. “Transparency” is set to 64 if an opaque logo is used. The Opaque logo can be created by setting
the “Transparency” to 64. Semi-transparency effect can be generated by setting the “Transparency”
to a value between 0 and 64.
7. After the Logo is properly configured, turn on PGM to enable the logo on the Program screen or
PVW to enable the logo on the Preview screen.
8. Exit the menu.
