I've recently bought a Blackmagic Design Decklink HD Extreme 3(connected to slot 2) to pull in and out SDI with FCP 7.
The codec I wanna use is ProRes
My Mac Pro is running under Mac OS X 10.6.8, 2X2.66GHz 6-Core Intel Xeon.
I've connected the cables from a Blackmagic SD out to a VCR in and from VCR out to Blackmagic in. The out ref switch on the VCR(DSR-2000A) set to input video and I check the AV output through the VCR.
The problem occurs when I try to capture from the VCR while connecting VCR and Blackmagic each other.
The video monitor has a sparkly screen or seems like drops a frame every other but the sound is normal.
And I drag this new clip into a timeline and play it, it looks a bit different but still sparkly. Also, the sound isn't the same as I captured it.
