  JVC’s BR-HD50U analog component output

  Posted by Beak on November 2, 2005 at 8:17 pm

  I have a decklink extreme card and was wondering if with the analog component outputs of JVC’s BR-HD50U deck could I capture HDV 720 30p footage via the decklink card? I’ve captured from the camera via firewire and downconverted by importing the footage into a 10bit sequence/project. However I’d love to capture directly to the blackmagic 10-bit (or any other for that matter) codec.

  Hi Beak,

  The Decklink Extreme cards can only capture standard definition formats, but allow you to down convert if you have aquired HD footage by some other means. I am currently using JVC’s deck in a project, intercutting with Digibeta. I’m using the BR-HD50U to internally down convert the footage to SD before outputting to my Decklink Extreme. It does a pretty good downconversion.

  Not what you want to do obviously, but save buying a HD Decklink card or inputting over Firewire, it’s the only way you’re getting a component signal into your suite.

  Don’t forget, capturing to another codec will NOT make the image better quality.
  The only advantage in doing that is that the CPU no longer needs to work as hard to give you RT editing functionality.

  Hey Thanks Steve,
  Thats what I was thinking but I wasn’t sure. So the down conversion right out to the deck looks pretty good? How does that work? Is it just a menu setting or switch on the front of the deck? IS the down rezed footage 4X3 full screen or letter boxed?

  The reason I like to convert to 8 or 10-bit is to take advantage of the decklink features like realtime effects and monitor output. It also holds up better to graphics & compositing. Plus I end up outputing to SD anyway. Usually Beta SP or SX.

  I have another workflow question maybe you can help me with. If I was to say edit a commercial or promo using all HDV footage. Would it be best to edit my video sequence in HDV then downconvert to a blackmagic codec before I start adding graphics and stuff or capture in HDV then start editing in blackmagic codec?
