Adding Lower Thirds to ATEM

Adding lower thirds to the ATEM mixer is simple.

1. Have your PC/Laptop plugged into one of the video input channels (usually channel 5).
   
2. In the ATEM software, go to the Palettes tab and select Downstream Keys.
   
3. In Key 1, set both Fill Source and Key Source to PC (or the channel you are playing the lower thirds into).
   
4. On the ATEM mixer, select the camera you wish to use.
   
5. On the mixer, turn DSK1 to ON.
   
6. On the PC, use the arrow keys to move through your lower thirds.

To make the lower thirds solid and not partially transparent:

1. In the Palettes menu, turn off Pre Multiplied Key and adjust the Clip and Gain.
   Clip (20%) and Gain (80%) should be OK but you may need to experiment.
