Ok,  here’s what worked…….. Thank you Terry!!!

So,  the whole problem is internal sync won’t work.

“The stop light should be blinking on your deck as it has no reference.

The capture tool in MC is set to SDI input and audio is set to SDI also?

You MIGHT be able to cheat reference by taking the composite out of the deck and feeding it to the reference input of the Mojo. This would theoretically lock the Mojo to the deck assuming the composite out and SDI out are in sync. This is not for the
squeamish, but it's worth a try.”

Again thanks to everyone! Especially Terry!
