Hello Everyone (This is my first post) Thanks for the good info. I have an SDI related question.. I have 3 SDI cams connected to SX-SDI. camera 1 is also carrying my program audio through the SDI channel. but there is only 1 SDI audio control in the Audio mixer. (SD0) The problem is when I switch to a different cam durring the live feed I lose the audio from the SD0 channel unless camera 1 selected in preview or main. How do I get the audio from the SDI cam 1 to stay active all the time.
