Thanks for the reply! Yes im very familiar with the ett window and all of my audio tracks are definitely enabled. This error occurs even if I try audio only without video. We use an external black magic sync generator sending ref into the matrox and the deck. I’ve tried it with and without the external ref. No luck. The frustrating part is it does not happen every time it worked perfectly three times today when I needed to insert picture and sound. But tomorrow it may not. Very annoying
