No! I don’t want to hear that. I see what you are saying. The comparative data rate chart lists 1080 23.976 at 176 Mbps. Damn, stumped again.

found the white paper for ProRes 422. Found some first hand accounts of RAID systems and ProRes. I’m pretty sure that my setup for scratch disk is not enough. Plus I’m using HQ which is pointless, 422 is sufficient by all means, especially since we shot on a 5DMKII, there isn’t enough information to warrant HQ.
422 HQ requires 220 MB/s. With my sata connection speed and RAID setup, I’m not hitting this requirement, bottleneck or not. The real question is if had a 422 project, would it be a problem?
I’m pretty much 90% confident that in order to edit online ProRes 422 HQ, I will need a RAID card and an Array, or a capture card with acceleration, to sustain read/write speeds required. Therein lies the problem. I now know better and will stick with 422 for most projects.
It’s always the obvious isn’t it? Thanks for the help everyone.

Hi Josh, thanks for the reply:
– Photos are mostly jpg, sized according to use. Some are tiffs, which I have had problems with. I had major issues with PNGs crashing my FCP so I avoid those at all costs. I’m also using psd files with transparency.
-I acutally haven’t had to use After Effects on this project, which is abnormal. I hear you I had that exact problem before with the framerate. Anyways, the 5DMKII was shot in 1080p30 (24p firmware came out in the middle of production so we opted to continue what we were doing instead of changing workflow half way through). What I’ve done was altered Philip Bloom’s workflow. Transcoded footage to ProRes 422 HQ with Compressor, sometimes MPeg Streamclip, then conformed to 23.976 in Cinema Tools. If I needed to retime it for audio sync I would do so with Compressor, but any B roll or shots that would be over VO I just left it. This workflow helped alot with the Jello effect and some of the aliasing inherent in the Canon HDSLRs.
I went this way because the final product looked better than the normal Transcode AND Conform with Compressor in one go. Compressor did a horrible job with predicting motion and the movement and pans were stuttery and blocky. MPeg Streamclip was fast, and the conform with Cinema Tools really made it smooth and nice looking. If I needed lipsync, then I would go to Compressor and retime that specific clip.
– Yes, I’ve repaired permissions AND tried doing a Safe Boot to try and fix any problems. It helped a little but eventually it was the same old same old.
– Audio are wav or aiff. No MP3s I’ve had those hellish problems before too.I’ve spoken to a number of friends about this. One of them, an Apple certified FCP rep, said that it is most likely the bottlenecking happening with SATA connections. Because I’m stuck at 7200 RPM 3 GB/s drives, the throughput is just not being allowed through, even though my RAID is clocking in at 190 MB/s. He is pretty sure that if I invested in a RAID controller to allow me to use an external RAID array, thus allowing me to use 10k drives at 6 GB/s, faster connection such as SAS or fiber optics, my problems would be solved.
Another thought is that my RAM and my RAID drives are all new to this project. I have to do tests to see if there are any issues with this hardware.
I also think that my directories are a bit scrambled and a little house cleaning could help. I did a test with a Quicktime output of the whole timeline, same codec and settings, brought it into a new project, streamed from my RAIDs. I only got 2 interruptions in the playback. That’s a sign for sure I think.
Let me know what you think, thanks.

because this is the first project with this new RAID 0 installed…

As in high quality scrubbing?
No I have not had this problem with SD or any smaller HD same codec projects. This is the first time with this problem, and it’s with a much more complicated edit. I think Rafael might be right, it’s my system directories…Mac 2.66 GHz Quad Intel Xeon

Sorry Rafael just saw your response. I’m a little afraid to run anything of that sort right now. But I will definitely do this after I deliver this, and with a media managed backup offline.

The dropped frames are random, at edit points sometimes, at transitions, in the middle of the clip.
The audio waveforms are usually turned off when I’m not dealing with audio. I try to keep it all pared down by turning off clip names etc.
Canvas and Viewer are at Fit To Window. Turning off Mirror on Desktop helps alot, but what the heck? I have to go through so much just to watch it down?
16 bit audio will mess up our workflow by throwing off timing since we’ve been working in 24. I also keep my RT Audio to 4 tracks usually, depending on what I’m doing, and on Low in my User prefs.
The link Jerry sent was helpful in understanding RT Extreme. I’ll try some new settings.
Unfortunately, the opening of the show is tomorrow night, so I don’t want to do anything drastic at this point. I’m going out to BluRay tonight. When I get this done, I will Media Manage and then clean up the system and RAID a bit and see if that helps. At this time I plan to do some serious testing with my project (backed up of course) and I will report back to this thread. I will also look into Disk Warrior.
Thanks for all the suggestions!

HUH, didn’t know that. Still learning everyday, and till the day I die.

Oh and I should add that energy saver and screensaver and all that is always off. I always render. When I’m doing grading or anything image critical, I do need to see things in high quality to make the best decisions.
Jerry: You’re saying even though my playback setting are on medium or low, if I render the clip with effects, etc. it will automatically play at high?

Thanks everyone. I have run TechTools and drives seem fine. I will try to keep it on Unlimited, but in the past it brought more errors than not. That’s a good point though Jerry, and didn’t think of it that way. Even with filters, effects, I always render it, whether it’s a green or red bar.
Still stumped. And thanks for the feedback.
