I have quite a simple sequence with linked media (range of sources but mainly 2k Pro res) as the base layer or Avid MXF DNX185 Media.
If i add a Pro Res 4444 Quicktime top the layer above i drop a huge amount of frames during playback.
The Pro Res has an alpha as its for some motion gfx, i've checked my CPU useage during playback and also the disk speed of my RAID which is way above the streams being asked of it.
So i can't figure out why Avid is struggling so much with this.
I'm running MC 8.4.5 on a dual 8 core Z820 with a Quadro K4000, 32 GB RAM, Windows 7 Pro 64bit, Quicktime 7.7.8, Nvidia driver 353.82.
If i render then all's well but i would expect Avid to be able to handle this...
Anyone have advice/experience on getting better playback of linked (read AMA) Pro Res 4444 with an Alpha?
