  A few questions about 5.1, Tiger, DL Extreme, FCP 5

  Posted by Tangier Clarke on September 12, 2005 at 3:48 pm

  Here is my config: G5 Dual 2/4 GB RAM/ 250 x2 Internal SATAs/ 3.5 TB Xserve RAID (connected via apple fibre channel card in slot 3)/ ATI Radeon 9600 XT/ ATI Radeon 9200/ Blackmagic Decklink Extreme(Slot 4, PCI-X) /Tiger (MacOS 10.4.2)/ Final Cut Studio/ Apple 23″ HD Cinema Display(connected to Radeon 9600XT)/ Apple 17″ Cinema Display(connected to Radeon 9200)/ Sony 50″ Wega DLP (Connected to Radeon 9600XT)

  – Does the 5.1 software downconvert DVCPRO HD to NTSC in real time?

  – Is the hardware based HD up/down conversion feature greyed out because I don’t have an HD card or because my fibre channel card is in slot 3? (there is a mention about having an HD card in slot 4 (PCI-X) and apple fibre channel card in slot 3 in the Blackmagic READ ME file

  – With the DL Extreme and 5.1 is it at all possible to downconvert DVCPRO HD to NTSC during playback in real time?

  Hi Tangier,

  [Tangier Clarke] “Does the 5.1 software downconvert DVCPRO HD to NTSC in real time?”

  Yes. HD material for down conversion must have a compatible frame rate with standard definition video. You can use HDTV 1080/59.94i or 720/59.94p for use with 29.97fps NTSC.

  If playing out HDTV 1080/23.98p material and down conversion is desired, choose a Blackmagic HDTV 1080 23.98 -> 59.94 easy setup. This will enable 3:2 pulldown and convert the video to an NTSC-compatible frame rate so that down conversion can be used.

  See Down conversion with DeckLink cards for further details of the down conversion capabilities of DeckLink cards.

  [Tangier Clarke] “Is the hardware based HD up/down conversion feature greyed out because I don’t have an HD card”

  Yes, it is grayed out because you don’t have a HD card. However, you can still use your DeckLink Extreme to down convert HD material to SD. Just select a Blackmagic HDTV 1080i/59.94 or Blackmagic HDTV 720p/59.94 easy setup in FCP 5. When you play out the HD timeline, it will automatically be down converted to NTSC on output in real time.
