Exporting really slow/stalling even on Promise Pegasus R6
I am trying to export a Ceremony multi-cam edit in Premiere. It’s a little over an hour long duration. When exporting directly from Premiere (H.264, HD 1080p 23.987 preset… target and maximum bitrate = 8) it will get to about 2% and just stall, and the wait time says it will take over 14 hours.. then that number just keeps going up the longer it sits there. Meanwhile, using other applications on the computer is near impossible as the entire machine lags like crazy.
Curiously, when I export from Adobe Media Encoder, it seems to be movie along more steadily, albeit much much slower than I would expect when exporting from a Promise Pegasus R6 (RAID 5) via thunderbolt… but then it slows to a hault about 1/4 of the way through and just sits there and the estimated wait time just keeps going up. When exporting through AME I can use other applications on the machine just fine.. seems to move along smoothly, however when I try to edit, even on 1/4 resolution playback is really laggy.
The same stuff happens on other projects I’ve tried exporting. Just super slow and laggy, and export freezes up. It just started acting this way over the past week.
Below are the specs for my main workstation, but I’ve tried exporting a different project I’ve been having similar problems with on both this workstation and my Macbook pro (2011, mavericks, 16GB RAM, SSD drive) and it does that same stuff. The export just sits there. Help! Can’t afford to lose this much time on projects!
Specs:
iMac 3.4 GHz Intel Core i7
OSx 10.9.2 (13C64)
16 GB memory 1333 MHz DDR3
AMD Radeon HD 6970M 2048 MB
Stock hard drive (not an SSD)Files are on a Promise Pegasus R6 set to RAID 5

To be honest, the most vital component in determining exporting speeds is actually the processor as opposed to the drive that you are exporting to.
What is the source material for the project – is it identical to that you are exporting to, or are you doing any kind of cross-conversion (this would add time to the export).
It would be interesting to have the Mac’s activity monitor (Applications > Utilities > Activity Monitor) open whilst you are running this, and just see how hard the processor is working. Yes, you have a pretty good processor in there, but it is interesting to see just what it is capable of handling, particularly when you ask it work to do the processing!

The CPU is not being overly taxed during export. I’ve already checked activity monitor. In this particular project, I am exporting DSLR footage to H.264 1080p 23.987. The footage is 1080p 23.987 fps. I’m not sure if that is an exact match though? I am changing the bit rate down to 8 for a smaller file.
It’s not even that it’s slow – which it is – but it literally gets stuck. I tried exporting the same sequence off a different hard drive (I copied the assets and project file over to a firewire 800 external drive…which I would expect to be much slower than the Pegasus, but wanted to see if the Pegasus was the problem) and it did the same thing.. just got stuck.. I left it overnight and when I left it was at about 12% and said it would take another 6 hours or so. came in this morning it was stuck at 26 % and it said it had 48 hours to go. That really doesn’t seem right.

Additionally, I tried exporting a 7 minute clip yesterday – AVCHD file from a Canon C100… no crazy effects on it just a little fast color corrector – and exported it H.264, using the Vimeo 720p 23.987 preset, and it took a couple of HOURS to finish exporting. This was again via thunderbold through the Promise Pegasus R6. There is no reason ONE clip should take that long.

No, I must admit, these times do seem excessive.
How long does it take to export to, for example, the second 7 minute clip to the desktop as a test. This will help us rule out or focus on the Pegasus drive.
Which version of Premiere are you using? Have you tried trashing the Premiere Prefs?
Adobe Media Encoder preferences can also be cleared by:
Try going to “~\Library\Preferences\Adobe\” and then delete folders “Adobe Media Encoder” and “Common”
This will put AME in default state and remove media cache. Custom presets will also be deleted so make sure to back them up.
[copied from Adobe Forums].I always recommend just moving any preferences files out of the folder, rather than deleting them in case there are any problems (although in my experience, this is extremely rare).

I’m using Premiere Pro CC. Everything is up to date.
I tried trashing the preferences as you suggested, and am testing this 7 minute AVCHD clip. Exporting with the same settings as a few days ago (vimeo 720p 23.987fps preset). I am exporting it to the desktop, and it’s still taking way longer than it should. It’s been running for about 30 minutes now and is only at 12%. I copied the project over to another drive so I could test the speed on a different machine, and a different hard drive. Similar results. Really slow on my 2011 Macbook exporting to the desktop… running the project through our mac mini server via ethernet, which for a clip like this should not be a problem. I’ve exported much more complicated projects via the server without issue in the past.
I can’t imagine what the issue could be! I’ve tried everything I can think of for days now, and all our projects are getting backed up because stuff is just taking forever to export. If you have any other ideas, let me know!

It certainly is unusual.
How long does it take to export a clip of 1 minute of bars and tone, no effects? This is about as simple as you can get!
Have you attempted to export to something like a QT Pro Res file?
One other trick I have used in the past is to nest the whole sequence onto a new sequence. Sometimes this can get over any difficult hurdles that are presented by any effects.
Do you have any third party plugin effects on there, or is it all native PP CC effects?
Is the mercury playback engine activated (if supported on your machine)? Maybe try the opposite setting there?
