hey guys,

update: for reasons completely unknown to me, changing my video card from the stock NVIDIA card to an ATI mac radeon fixed everything. thought this might be helpful to others, and thanks again for everyone’s help.

Thanks guys! I have a gut feeling it’s software related, if for no other reason than that a full-res QT made from the same rendered sequence plays flawlessly in QT Player but not in the timeline—from a disk and CPU perspective I’d say those should be equivalently taxing on the system.

I’ll work my way down those (very helpful) lists and get back to you guys…

Yep, I’ve tried the project on multiple machines (most lower spec’d, actually) and it works no problem. And I don’t think it’d be a drive issue because according to the write/read tests on the actual throughput on the actual computer, it’s only using about 20% of the available performance bandwidth.

The video card is lower-spec’d than the slower computers, but given that it’s playing something fully rendered that should be an issue, correct? Also, this is my first FCP7 project (I hung around to 6 for ages)… I can’t imagine a scenario where that would have anything to do with it, but who knows.

Like I said, totally pulling my hair out over this. Thank you guys for all the responses so far, btw.

Thanks for the responses guys, I’m working through some of those lists of things to try.

The thing that’s most confusing to me is that these exact same projects, on the exact same drives, on the exact same (or lower spec’d) machines have absolutely no problem with any of this.

And as far as the numbers go, my drive is testing at 60MB/sec (byte, not bits) write and 75MB/sec read speed, and the files I’m playing back are 16.50MB/sec (all of these figures are from the Aja tools). At that rate I should be able to easily play 4 layers, and my computer is dying getting through one second of one track…

It’s ProRes 422 (non-HQ), and yep, the footage matches it exactly.

I’ve been trouble shooting problems like this for years, and I just cannot explain this one.
