Setup:
hdmi camera into elgato hd60 then to vmix computer
second computer running presentation software to projectors and VMix desktop capture app over lan to vmix computer
Microphones and presentation pc audio going to a mixer board then to vmix computer


Our camera inputs have about 1 second delay.
The audio input sound coming from the mixer can be delayed to match the cameras, but the desktop capture input cant't be delayed to match the cameras.
The audio is off ether when I switch to the camera or when i switch to desktop capture. depending on if i add a delay to the audio in.

How can I add a delay to the desktop capture input to match the cameras?
Thanks

Edit: tried the 2nd hd60 at the same time and vmix would not recognize it. even on seperate usb contorllers, even 1 on usb2 and 1 on usb3 the stystem only recognizes 1 at a time.
