Help me identify problem for slow export on a powerful machine
archie29 Nov 24, 2013 3:59 AMHi,
I am exporting an interview in Premiere Pro CC. It is 1:45:00 long and it has been 20 hours since, but the export is only 94% complete.
Project & Footage:
The footage is a combination of DSLR footage - 5D Mark III, GH3, 650 & 550D.
The edit is all straight cuts with: {a} Color corrector on each clip to match all cameras {b} NEAT - reduce noise on around 10% clips {c} Sharpen (10-30) & {d} An adjustment layer overall with a 3-way color corrector for a simple color grade.
Hard Drives:
- E: SSD-RAID for the source footage (Samsung 840 SSD on RAID-0)
- D: SSD for previews and cache (Samsung 840 Pro)
- C: SSD for Windows, Adobe CC & all programs (Samsung 840 Pro)
- G: Simple Seagate Hard disk for Export (used to be a 3 disk RAID but 2 drives crashed some time back)
Other Machine Spec:
Intel i7-3930K overclocked by 10%
64GB RAM
GTX-770 GPU
This is my longest project to date in terms of total time, but last time I did a 1:00:00 project, took around 2 hours not 20.
My concern is I need to understand where the bottleneck is?
My CPU is hardly working a sweat - 40% at max
My RAM is plenty - being used 40-70%
GPU is not even being used in anything (see it at 0%)
Disks (which I was sure was the bottleneck) barely cross 10MB/s
Checked the "power options" in Windows also - everything is set to maximum performance.
It was a big mistake not to send it to Media Encoder as I could have continued editing a different project. Biggest. Mistake. Ever! (no idea why Adobe does not make it a default behaviour?)
I am fairly new to the industry and till last year was using a MacBook Pro until I started getting demanding projects.
I want to know is this normal? If I had used NEAT video for 100% footage then probebly I could have understood this, but its used for only 1/10th of thr footage and I have used NEAT before (but on After Effects CS6) on my Macbook pro (nowehere near as fast as my current machine) and it only added a small overhead - nothing of this sort.
I expected maybe 3 hours to export this 90-100 min seqeunce, not over 1 day.
So what could be the reason? Why isn't one of the above (CPU, RAM, Disk, GPU) at 100%?
I expected 1 of these to be the bottleneck but nothing is crossing 50% even when it should be on full blast.
I dread what if there is small tweak required in the edit once its complete. This video is due on Monday, I would have to reencode for 24 hours.
Please experts - let me know your thoughts. Could it be that Creative Cloud Windows is slower than CS6 Mac & its not a hardware problem?
I am sure I am missing some hardware that is causing this bottlenck. Attaching resource Monitor screenshot (let me know if I should use some benchmark software for you guys to get more information).
