It ws my intention to use HDMI to output the computer (HP Laptop) and then use the audio out on the computer to the audio mixer. However, when the HDMI port on the computer is used, it disables the audio output on the computer.
I am connecting the ATEM switcher to the Hyperdeck Studio by taking an SD/HDSDI output on the switcher into the SDI input on the Hyperdeck Studio. The .mov file I get from the Hyperdeck studio is 4X3 while I am outputing an 16X9 signal (via HDMI)to the main monitor, projecter or whatever I am using.
