Not likely at full res, but then you don't have an alternative.
I am playing back FullRez DPX & Tiff in PPRO.
I have a RAID0 consisting of 4 Drives giving me sustained R/W of 500+ MB/s.
I amn skimming thru' the timeline with NO delay or nothing. Great.
MUUUUCH better than editing with ANY compressed codec.
I have a GeforceGTX285 but I dont think that graphics card has anything to do with that.
This boils down to sheer hard disk speed.
Correct me if I am wrong ;-)
I think Aton is right on this one. Assuming the media and sequence match, the graphics card won't help at all with simple playback.
Thanks for the feedback.
Sounds like i need to upgrade my raid.
However i was thinking of the mercury playback engine that the quadro card enables.
I know that it makes it easier to playback RED r3d files but what about image sequences is there annything to gain or no ??

Hardware acceleration doesn't make it easier to "play" any media files (assuming they match the sequence). What get's accelerated are certain effects, scaling, deinterlacing, blending modes, etc. But not simple playback.

The graphics card doesn't help at all with decoding, nor does it help with reading the data off the disk faster. The reason that people talk about the GPU helping with formats like RED is that you are nearly always scaling RED footage down to use it (since you're almost certainly not using a 4K sequence, and you're almost certainly not previewing on a 4K monitor). The GPU helps enormously with scaling operations if you have a card that Premiere Pro can use for CUDA processing.
DPX image sequences are slow to preview for two reasons: data rate off of the hard disk and CPU speed for the relatively slow decoder. Fast disks and fast CPUs are what you need for fast DPX playback.
My set up is a
Mac pro with Two 2.66GHz 6-Core Intel Xeon “Westmere” processors
20GB of Ram
And an internal raid of 3x1Tb stripet togheter running about 300mb pr sek.
Shouldent that be able to do the trick ?
That raid is about bare minimum for simple timelines, but insufficient for a 4 camera multicam editing session.
That 20 GB of RAM is not really enough, that is only 10 GB per CPU and only 1.66 GB per core. With my single 6 core PC and 24 GB there is a tremendous difference in my performance especially as I upgraded from 12 GB.
