NOTE: Uploading of images has been tested on the ATEM Mini Pro set to 1080p. Testing has not been conducted on those ATEM switchers that support SD, 4K, or 8K resolutions.
NOTE: Still images seem to revert back to their original filename when a new controller (MixEffect, ATEM Software Control, etc.) connects to the switcher. It is possible this happens because the switcher is re-reading the file stored in its non-volatile memory.
