Best guess is that even the 950 isn't powerful enough for 4 compressed HD tracks.
Check that your memory is running @ 1600, not 1066 in the BIOS. And add an extra SATA disk.
I just checked the RAM settings and timing to be sure that they are correct,
which they were.
I just added another 1TB hard drive... Do you suggest that I do a RAID0?
I've never done this before... do you know of a good guide that could walk
me through it?
Take note than with your media, the CPU will be a far larger influence in smooth playback than will a RAID. I have no trouble working with four DV streams from a single hard drive. HDV and AVCHD have the same data rate as DV. But they require a LOT more processing power.
Before you spend the time and money setting up a RAID, try out some DV media and see if you really need a RAID.
I hope this info will help you ,
a weak ago i needed to cut with multicam 2 camera footage format AVCHD , each footage was 1 HOUR Long (1080@50i).
when both footage was on my raid 0, multicam didnt run smooth.
i plug to my computer addtional external hard disk (eSATA) and paste one of the camera to it.
the multicam was running much more smoother , meanning (i just think so ) when each camera is on seperated phiysical HD ,multicam can run faster.
notice that avchd format is quiet complex for any NLE compare to XDCAM or HDV .
i meant AVC-intra not AVCHD .
AVC-Intra does have much higher data rates, and will depend heavily on both the CPU and the disk setup.
Well I added the third hard drive per Harm's link. It seems to be cutting
smooth once again. I have more testing to be done, but it looks like that
solved my issue as of now. I will report back and award answer as soon as I
have a chance to finish cutting this set.
Is there no way to pre-cache the multiple video streams into RAM? I am having the same issue, but have easily enough RAM to cache around 10 decompressed minutes of the multiple streams I''m working with. Looking at the disk and processor activity though Premiere seems to be only requesting footage as I need it...
PP doesn't do RAM Preview like After Effects does.
Are you still having the same problem? I was getting the same results. In my case I am using an external monitor and I had the "Desktop Video Display During Playback" disabled. Once I enabled that setting multi-cam started working for me. I see this was over a year ago but maybe it will help someone else in the future?
