I miss SD-SDI too, but what are the "so many other functions" that you are missing ? This does more than the Panasonic AV-HS or Broadcast Pix, right ? Are you specifically wanting built in streaming ?
What else ?
We have completed standard definition support on the ATEM 1 M/E Production Switcher. The software update is version 2.0 and is available now on the support page of our web site. We have also fixed a few minor bugs.
To perform the upgrade, you will have to download and install the version 2.0 software on your Mac or Windows machine. Once the software is installed connect your computer to the ATEM Production Switcher using a USB cable and run the ATEM Setup Utility. The software will prompt you to update the internal software. Repeat with the Broadcast Panel if you have one.
We have more software updates coming, so please keep checking our web site for updates.
