Why is FCP5 so sluggish???

[David Robinson]

Toby, i have that same sluggish feeling. Kind like that first version that ran on OS X. I have a sequence set to Apple Uncompressed 8bit and its sluggish when scrubbing through the timeline. All of my clips are graphics or photos rendered from AE with the Apple Uncompressed 8bit codec. I also have a Decklink card and have Effects Handling set to Final Cut Pro, but when I change effects handled by: to Blackmagic SD the sluggish timeline goes away. Don’t know if this is a solution, but you’re not the only one experiencing the slow down.

We have a very similar setup, except a Atto UL3D with a U160 JBOB. Lag between button and play is minimal (1/3 second tops.)

Scrubbing is VERY buggy. Playback at 2x is unusable.

I honestly think the problem is a combination of a buggy OS fighting with underbaked RAID drivers fighting with the FCP5 video engine. I don’t think there’s ANYTHING wrong with your setup, but it’s going to take some patches from Apple.

Have you tried reading 8bit UC files off the internal SATA?

2x playback works great here both with Fibre Channel and FW800 drives. Scrubbing is also just fine with either. Definitely SCSI is not as well liked with Tiger as it has been in the past.

I, too, have seen this sluggishness! I edit in the IMX codec on one system (Dual 2.7 G5 with 4.5 gig RAM – Tiger), the other uses DVCPRO50 (Dual 1 gig G4 with 1.5 gig RAM – Tiger). Now, the only things in common are they use Tiger and both are using FCS 5.02. And after about an hour of running, my Dual 2.7 gets real slow. I have to shutdown FCP 5.02 and restart it, then its fine for a while.

Toby,

Have you tried to callibrate the Frame offset? When I first got the Io, I had to set it to almost 12 frames. Do you always playback with an external monitor?

Frame offset is only for calibrating your output device, this is a system wide problem. But thanks for the thought.
