  some driver wierdness 5.0/5.1

  hi there

  wondering if anyone else has seen this problem w/ Decklink HD Pro – FCP5.02
  we’ve cut a project at OfflineRT with orginally captured from digibeta with a Decklink Extreme
  now we’ve recaptured at Uncompressed 8 bit 1080/60i from HDCAM originals using a Decklink HD Pro card

  the first issue was that the output to our HD monitor was letterboxed … checked in the Decklink PrefPane and sure enough the HDTV Up/Down Convertor Output was “On” by default, set to SD-Letterbox 16:9 …. so I turned it to “Off”.

  great, the monitor now corectly displayed the output unletterboxed.
  just for kicks, I reopened the Decklink Preferences and sure enough, despite the now correct output to the monitor, the setting for HDTV Up/Down Convertor Output had reverted to SD-Letterbox 16:9. …. hmmm, wierd.

  anyway, inconsistent reporting of settings aside, it was working right ?

  …wrong! it was still downconverting to SD, it just wasn’t letterboxed!
  no amount of messing with the prefs would make it work.

  time for new drivers … downloaded and installed ver 5.1.

  opened the prefpane and again downconvert was enabled by default. set it to “Off”
  checked the output and huzzah! all was well in HD to monitor land

  just for some more kicks, I again reopened the Decklink Preferences and blow me if the Up/Down converter settings hadn’t reverted again.

  ok not to worry, as long as we’re getting true HD out to the monitor it doesn’t really matter what the driver prefs say (although if and when the mac gets rebooted we have to go back in and reset the prefs everytime)

  does anyone else see this strange behaviour?
  cheers
  Andy
