Lower Third and Chroma Key at the same time in ATEM 1M/E 4k

Hello,

I have a ATEM 1M/E 4k production switcher.
I want to have a chroma keyed video with another camera input on top and also a lower third all at the same time.
I can easily chroma key a source and add another source to the background but i want to also add a lower third.

Is this possible with the 1M/E ?

You have four upstream keyers and two downstream keyers - as long as you can key the lower third properly with either of those, this is not a problem.

This is true no matter whether your lower third comes from a video input or a media player.

The switcher isn't allowing me to have 2 keys on at the same time.

Check the order you have them keyed over. Are you using upstream or down stream keys?
