FCP on 8 core – Real Sluggish – Has this ever happened to you before?
Hey guys,
I have been working for quite a while and don’t really know when this happened or if it even did at all since I really just started doing some editing with an HDV 1080 60i timeline using the ProRes codec.
It is very sluggish and has a hardtime even playing anything back in realtime.
The Main Drive for the Progect is a Graid2, the OS is a veolciraptor. I did a reboot but no cigar. It seemed to be pepppier before I ran a ton of compressor tests earlier yesterday nightish.
Does FCP ever get sluggish and what can one do about it?
The 1TB Graid 2 is on Firewire 800 and has 400 GB free. The OS 300 GB velociraptor still has 140 GB free.
Any ideas, or is that timeline with a prores codec just sluggish?

Also ever since I switched to using the ProRes codec, I get a bright green bar on my timeline and those sections don’t render, at all.

Hi Elijah,
the first thing you should do is test your drivers speed. You can use the AJA System test tahat you can download free from the AJA website (Software downloads> Kona3).
Have a look to to the Activity Monitor to see how much CPU is working.
You need to know if FC is engaged in a complicated process or if is just performing low.
If you think that is performing low: Rebuild all your HDs directories.
Cheers,

Hey Rafael,
I checked CPU and it was very low. When I do renders it only uses about 40% of my cpu, I wish it used more, they said ProRes was supposed to be multicore enabled.
My Drive speed on the Graid2 (Raid 0) with the AJA System Test is 65MBps Write and 80 MB/s Read. My velociraptor is 85 MBps Read/Write and my Raid 5 (scratch disk) is 150 MBps read/write or something around that, just tested an hour or so ago.
So:
OS = 85 MBps read/write
Scratch = 150+ MBps read/write
Project Drive = 65/80 MBps Write/ReadThis should be more than enough drive speed for 1 or 2 streams of HDV (ProRes render) with a few transitions and Boris 3D titles right?

How much RAM do you have? you should have at least 1Gig per core..
hmm… I wonder what this button does…

I have 10 GB of Ram.

Elijah:
Time to optimize your system.
DiskWarrior, TechTools or Drive Genius.

FW and a large ProRes project, or even a medium pro res project will cause some sluggish operation.
Also, turn off the thumbnails and audio waveforms in your timeline if you haven’t already.

I hadn’t heard of any of those until now. I guess we get Tech Tools Deluxe for free since we have the Apple Care Plan. I am downloading the DMG now.
So, I never got a clear answer on this. My setup should be pretty peppy, right?

Thanks Walter. Just as I went to turn those off FCP crashed flat out.

Your FW drives are the weak link. They are pretty slow for extensive pro res editing. Especially the GRAID 2 units which I had a lot of issues with them being particularly slow. I sent them back. My original GRAID’s are much faster than the 2’s were.
If you can step up to eSATA or SAS/SATA you’ll get much better performance.
