Hello Luke,
Thank you for the support.
Well, I think I’ve already tried most of your suggestions. I output a Pal signal from FCP, the monitor is Pal.
I’ve tried the deck control and the same thing happens : no signal on the composite
Same for desktop output.
My easy setup is Blackmagic Pal 8 bits.
I’ll be in the office in an hour and will check if my Decklink desktop is on Pal.
I will also try another decklink card (Extreme).
I’ll keep you informed.
BTW, Blackmagic has the best support I ever found on the web …Thank you for that !
Jacques
