Hi all I know that this is quite a late answer but I have found that if you have a 1080i50 signal and you get a black rectangle in watch out, sometimes 1080p25 setting in watch out production works well. Basically the same signal but the black magic driver seems to then wake up and pass video through.
On another note I have some clients that are struggling with the latest BM driver 10.4.2 for SDI capture on intensity cards. Has anybody else had this problem and can you suggest a driver version that works?
I will also take this up with black magic but I thought I would just check here first.
Thanks
Dylan
