Hi Grace,
The ATEM switchers are really quite different than TriCaster. TC offers ISO recording on multiple channels, the live streaming of course, and live set technology. Other solutions may offer just keying, but that’s a lot different than Live Sets. And TC offers the dual DDRs for playback of video and overlays. I believe ATEM is limited to playing only very short segments from memory, a couple of seconds for transitions/stingers.
If you are mainly interested in portable switching only, then ATEM is an economical choice.
