I like my new ATEM Mini Pro HDMI switcher but there are a few issues. The biggest issue I've found so far is the failure to be able to save the media in the Media Player. As far as I can tell if you shut down the switcher when you start back up the media files need to be dragged back into the software one at a time. This is a FAIL! The unit should be designed to retain all settings from the previous broadcast.
There is a procedure to save the settings and media but the files are saved on your computer and then need to be restored for each startup. This is time consuming and requires a computer to be nearby for the purpose. IMO the settings and images should be stored on the device itself.
