  Broadcast monitoring or hardware issues ?

  I’m trying to convince a producer to let me edit a feature documentary with FCPX. So i installed 10.0.5 on his edit station (on which were already installed Avid MC6 and FCS3) and I have to face performances issues.

  Mac Pro 2X2,66 GHz Quad-Core Intel Xeon
  Mac OS Lion 10.7.4
  14Go 1066MHz DDR3
  NVidia GeForce GT 512MB
  BlackMagic Decklink HD Extreme 3D

  Events (with media) and Projects are stored on a Sonnet Fusion R800 RAID
  (Write: 409MB/S, Read: 365 MB/s)

  I’m working with XDCAM EX HD420 1080p25, ingested in FCPX after installing Sony XDCAM plugin for FCPX.

  Blacmagic output is set on 1080p25 in system settings, same settings in FCPX.

  I tried to uninstall, reboot, then install Blackmagic Desktop Video 9.5.3, then 9.6 (and reboot).

  I read that some people changed this NVidia graphic card for an ATI, but I won’t be able to do this.

  First I noticed a strong strobe effect on playback when selecting AV output when FCPX playback prefs were set on High Quality.
  I tried to set BM output on 720p50 in system prefs, that’s the same thing. I can play in “best performances”, not in “High Quality”.

  Then I checked with AV output turned off, and I’ve also got drop-frames issues.
  Strange thing, Clips play fine from a project (only in “Best Performances” though), but not from the event.

  I tested same medias on my 2011 iMac (without broadcast monitoring…)on a FW800 Raid0 2 disks drive, and it seems to play fine in High Quality, from event or from a project.

  So I guess I have to deal with hardware issues.
  I tried repair permissions, trash prefs… etc.
  Shall I give up the idea of editing with fcpx on this station ?
