  HD-SDI capturing problems

  Posted by Todd Terry on June 26, 2008 at 6:00 pm

  Hi gang….

  Forgive the cross posting, but I may put this in a couple of forums as I’m not sure where exactly the problem lies…. Canon, Matrox, Adobe, or all of them or everything…

  Just as a test I’m attempting to do some capturing HDV source video via HD-SDI and am getting some very weird (and bad) results.

  Here are a couple of low-res clips (both the same, just different formats) to show you what I am dealing with:

  And here is a full-size screen grab:

  As you can see I’m getting stuttery, jerky video with occassional bursts of vertical green lines.

  Ok here are the technicalities:

  Source test footage was recorded HDV 60i with a Canon XL-H1. I am using this same camera for playback outputting via HD-SDI.

  My NLE is a PC, Matrox AXIO LE, in a pretty smokin’ fast Boxx computer.

  I’m capturing within Adobe Premiere Pro v3.0.

  My Premiere project settings are Matrox – HD 1080i 29.97 fps Uncompressed 10-bit. Within Premiere I am capturing as a Matrox AVI via HD-SDI.

  I know there is no problem with the tape. If I capture as HDV video rather than uncompressed 10-bit HD video it looks fine. I only see the problem when capturing via HD-SDI, and if I record “live” footage from the camera (not on tape) via HD-SDI I still get the bad results. I have swapped out the SDI cable, with no change.

  I’m not in the best “testing situation” as unfortunately I do not have any other way to test the camera’s HD-SDI output (I do not have an HD-SDI monitor), and I do not have any other cameras, decks, or other devices that feed HD-SDI so I can’t easily test the Matrox HD-SDI input with another source.

  I can’t tell if it is a hardware, software, or settings problem…. or a combination of several.

  Any thoughts or suggestions are greatly appreciated.

  T2
