  HDlink Pro – Interlace only?

  Posted by Sean Donnelly on February 14, 2008 at 2:37 am

  I’ve been using an HDLink Pro for the last two weeks with an EIZO CG241W, and I’m noticing an interlace blur with fast moving images. I’m quite sure that I do not have the interlace simulation turned on, and this does not happen playing the same shot via the 2nd DVI port to the same display (I spent a lot of time doing an A/B between them) so I’m thinking it has to be the HDLink box. Is it possible that the interlace simulation is stuck in the on position? I have fed it many varieties of HD and SD SDI, with no change.

  Thanks in advance,
  -Sean

  With no info on the edit system or file format you are looking at, the short answer is that Decklink cards correctly display interlaced images whilst a computer graphics cards DVI is not interlaced.

  Therefore if your footage is interlaced, the DVI is not displaying it correctly whilst the Decklink is.

  Michael,
  As I said this is an HDLink box, NOT a decklink card, and the source material is coming from a camera’s HD-SDI out. This happens with any format (1080p24, 1080psf24, 1080p30, 1080psf30, etc.)

  What build of HDLink are you running? Also, I’m using the same setup. I’m curious how you calibrated your Eizo. Did you use something like cineSpace to put a 3D LUT on the HDLink?

  I’ve noticed the interlace on 23.98psf material straight from a HDCamSR HD-SDI though a HD-Link DVI bridge also..
