  Decklink SP Downconversion for HDV

  Posted by Philipp Lew on November 21, 2007 at 12:32 pm

  Hi all,

  i have a Powermac g5 2 Ghz Dual with 5Gb Ram and a decklink SP card FW800 Raid HDD and two internal HDD. I’m using FCP Studio 2 with the newest version. I have connected a jvc PAL monitor to the deckling over YUV.

  I now tried to use the downconversion feature of the Decklink to view hdv content on the jvc. But i only get a still image on the monitor. If i press play in the timeline, the video is not displayed on the JVC. I used the HDV – 720p25 Codec for the material.

  What is wrong? Why is the card not displaying the video on the external jvc monitor in realtime?

  Thanks
  Philipp

  i got the same happening

  i reckon it is simple

  hdv is a nightmare as it is not iframe based and sticks (you are asking the card to downcovert on the fly whilst it works out which frame it is on on the fly in final cut pro it is very confused)

  try capturing any hdv to the prores codec through firewire from now on (heard it works on g5 as well which would be good) let us know as not working with hdv deck. prores is iframe based and shouldnt give you the problems. you need update from last week to get fcp 6.02 to use the firewire hdv to prores thing.

  you may find the firewire 800 is a bit slow and annoying with the data rates though
