Its not on the website anymore!
Atem SDI ( cheapest model ) also has NO multiviewer. And the reason behind it is because the cheapest models are meant for Game streamers. Setting up there game, live camera, some overlays and stream it to Twitch or YT... ( Instead of OBS )
It was never meant as a real live switcher and so never needed a Multiview out. Hence the thing is super duper CHEAP.
Strange.. i can't remember that the promotional videos from BlackMagic Design, about the ATEM mini, talked about "Game streamers" the examples shown, were about Vloggers and their Youtube channel, they did show how to use the ATEM mini in use with Live Productions, cheap ATEM mini models with SDI also have no use for "Game streamers"
The ATEM mini was to fill in the gap for people that only could use video equipment that have the HDMI video connection(s) Like said, the "Game streamers" used OBS and did not need the many features the ATEM mini had.
Only after many complaints from the vlogging Youtubers, improvements came in firmware and software updates, and the newer models. BlackMagic Design is more about video hardware, and not about "Game streamers"
Also….. the products of BlackMagic Design are better supported on the APPLE platform, great advantage of this also is the use of ProRes422 codec(s)
True, in this time and age you don't need to think about of buying the ATEM mini, it depends now, if you need SDI or not, otherwise there are other options to choose from, and not necessary from BlackMagic Design….
And yes, it stays confusing in the BMD documents, to find out which model has which features, they put it on a pile.
So if one wants to know at which software update/firmware a certain model was still supported, it gets complicated.
My advise would be check for use cases on the BMD forums, or also …..just on Youtube
