7.2 Placing text on the video using luma key
The SE-4000 allows the user to place a logo or
text image (ideally black and white) on the video
using the luma key function. First of all, create a
1920x1080 (16:9) text image against a black or
white background on a laptop. Once the text
image is created, please follow the steps
outlined as follows to insert the text image.
Note: If the text image is dark, choose a white
background; if the text image consists primarily of bright colors, choose a black background.
1. Connect the laptop to the switcher’s HDMI Input Port 9 (Input Channel 3).
2. On the SE-4000 control panel, press the Keyer button to open the Keyer menu on the 5
inch LCD screen.
3. Select Key 1.
4. In the Keyer Ctrl sub men, select “Luma” and “Self” to apply luma keying effect to the
connected input. The luma key removes the background, in this case, the black
component of the image.
