Hi Guys .
I had been outputting composite from my intensity pro 4k card as an external render from vmix.

I came in the next day after setting it up and I have not been able to get it to output composite again .

I've tried every setting I can think of .
updated the software .
Changed it to rgb32 and back .
changing the output resolution using the converter hd to sd on the blackmagic software video desktop tools.
Changing it to Pal ntsc and all the rest there. set the output to pal sd 720 by 576 50i 25p etc .
Followed the instructions in the vmix help and it has just disappeared.
It does output hdmi though but I need composite.( I'm going to try a hdmi to composite converter next as a workaround)

There is even a trick I've read where you can attach a component output and then switch back .
That is the last thing I have to try.
Has anyone else found a way to overcome this?
I've even uninstalled and reinstalled the card taken other cards out of the computer checked it's in a 4 lane slot etc.


Can't understand why it would just disappear like this . Oh and I've changed the cables etc.
