fcp 7 with mini-sas cannot handle dual screen with high setting
on Sep 29, 2011 at 11:48:01 am

Hi everyone,

I have a stardom mini-sas with raid6 configuration of 8x 2tb caviar blacks. My footage are mostly AIC footage 1080p25 and fcp is slowing down whenever I put the settings at high and editing dual screen. I'm using 8 core macpro so I don't know what's wrong because I believe the system should be able handling it very well together with the stardom. Any ideas on how to test which one is giving the bottle neck?

Currently I'm editing everything with single screen low resolution... not a nice feeling...

Thanks so much in advance

Santo

Download AJA system test or Blackmagic's disk speed test and see what your drive speeds really are.

On the surface, it seems your hardware should be able to handle 1080 HD, though you have not given complete specs.

Why are you using AIC and not ProRes? AIC is basically a legacy codec and inferior to ProRes in quality and performance.

Thanks John,

I have tried using the disk speed test and the drive seems to be working fine...

Its only giving me problem when it comes to fcp. other than that its fine.

Im using AIC only because it is faster to transcode to from the 5d h264 files. I use prores occasionally when i'm doing bigger projects.

thanks

Use Prores LT - you and your system will be MUCH happier!

Use ProRes and your system will work as it should. As you see, getting out of the gate as fast as possible causes problems on the backend.

Susanto,

What RAID controller card are you using?

If you're running the ATTO R680 card in RAID 6 you should be getting at least 800MB/s read/write. WD Caviar black 2TB aren't drives we recommend with the ST8-U5 SOHOTANK. We recommend Hitachi Ultrastar 2TB.

Thanks everyone, I will try to convert my next project to proresLT and see how we go.

Jon, im using areca 1222x. i guess its a little too late now with the hitachi. i wish i knew that earlier... nobody told me about this when i purchased it from the dealer. i think not many people are familia with the system yet. i was using hitachi 3tb at first, and then they say that the problem may be because the 3tb drives are still unstabile.. so we changed to 2tbs and i chose caviar blacks because they are the most popular..
