  blackborders with Premiere Pro

  Posted by Romekyn on September 24, 2005 at 7:00 am

  Hi,

  I’m new to this.
  I have my dual processor running XP with a Decklink Extreme hookup. My main concern is to capture an analog feed directly from broadcasta. Later, I’ll be getting a SDI feed.

  But, when using Adobe Premiere Pro,My capture produces black borders when using the Blackmagic default settings. I would rather capture at a 640×480 size, but I get a noisy signal when I try to import. Is there something I’m doing wrong?
  Thanks.

  Hi Rome,

  The black borders sound like analog blanking. When capturing via SDI, NTSC and PAL are 720 pixels wide compared with analog video which is about 702 pixels wide. Your DeckLink Extreme card is an SDI card which has both SDI and analog connectivity. This means that you get 9 pixels of blanking (black borders) on either side of the 702 pixel picture to make up the full 720 pixels of the SDI standard. That’s probably what you are seeing and there’s nothing wrong with that. 640 x 480 is not a TV standard format and you won’t be able to capture or output 640 x 480 with the DeckLink card as this resolution does not conform to the standards for TV.
