I bought two Canon XF 105 for our 3D shot.I did some test first.I use Mac Pro with Blackmagic Decklink Extreme 3D,latest driver 9.0.I set my two XF105 to 25P,connect these two camera to my card via SDI.Then I use Media Express to capture my clip.In Media Express preference,I set to 1080p 25 3D,10bit YUV.But I can not see any image from my camera.Even I set to 1080 25,I can not see image.But in FCP,I can see my image from the capture window with 1080 50i.Is there anyone can tell me why?Or tell me where is wrong?
Thx in advance.It is very argent.

I learn that XF 105 SDI output 50i singal wether you set to 25p or 50i.In media express, I can caprure one camera's image in 1080 50i.I plug two XF 105 in BM card's A and B SDI in.But when I set my project to 1080i 50 3D,there is no singal.Why?Any word will be appreciated.
