Dropped Frames Playback Decklink HD Extreme 3D
on Apr 4, 2011 at 12:50:13 pm

Hi There,

we got a Mac Pro 4,1 with a 8-Core CPU(2,26Ghz) and 6GB Ram.
Its runing the latest OSx and has a separate Raid-0 (software based) for media files.
We would like to use the Decklink Extreme 3D and the Media Express to playback 3D to our Barco beamer(L/R separate SDI streams) which works but the Media Express reports dropped frames. Our Files are 130GB(per eye) at ProRes HQ, the Blackmagic Speed Test shows me a data Rate for the Raid of about 270MB/s. I thought abaout the disk speed and added a third drive to the Raid but i also get dropped frames.
I encoded the files to ProRes(wothout HQ) and at least into LT but i allways get dropped frames after different time of playback.

Is there anybody out there who gets the same issues?
At least i tried to play back 2D(one of the 130GB ProRes(HQ) Files) and get dropped frames as well...where is the problem? RAM? CPU?
Our Raid is software based, 3x1TB Samsung HDD with 7200RPM per HDD.

Thanks for your help,
