Really slooooooww exports from FCPX
on Sep 10, 2015 at 6:05:06 pm

Hi,

I'm exporting single clips from a multicam file that has 2 4K r3d files and a 1080p ProRes file synced with some external audio.

Exporting from one 48TB raid to another one, via thunderbolt. One has over 3TB space, another has 17TB. Machine is a new Mac Pro, 6 core, 64GB ram, D700s.

With FCPX, a 1 minute file from 4k r3d source to 4k prores LT, is taking over 10 minutes.

I can export a full 40 minute sequence in adobe media encoder to prores and it takes just over 50mins.

How come FCPX has got so slow?

Does anyone have any suggestions at all - I;m sure it wasn't this slow a few weeks back....


Thanks in advance.

It's 4K RED to 4K ProRes LT! It's going to take a LONG time. RED at 4K is being deBayered at FULL quality, hence the slowest possible export. In the case of AME, that quality setting might be overridden by the source raw settings. I don't believe that's the case in FCP X as it goes by the system prefs REDCODE pane, which is probably set to auto. You'll probably get a faster export if you can run it through Resolve.

I know it will take a long time - but the RAW settings are the same in AME and FCPX. AME is encoding the files way faster. Like I said, a full 40 minute segment is being exported in less than an hour in AME, in FCPX a minute of r3d is taking 10 mins......

I can't get the files into resolve due to the complicated multicam edits. Hey ho - just looks like a long night watching render bars!

[Tom Sefton] "FCPX a minute of r3d is taking 10 mins"

Assuming that these are indeed both at full debayer quality, then yes, that does seem a lot longer than I've experienced with a 2010 Mac Pro tower.

It's really odd. The performance in FCPX seems to have nosedived on this machine in the last 48hrs. I've had Mac support try a few things but I can't tell what the issue might be. Unless some RAM has gone faulty or one of the D700s has given up....

Have you opened Activity Monitor and watched what's happening in the processing stream?
Or run BlackMagic speediest to make sure your hardware is running as it should?

Might give you a few clues to follow.

Same things happening in activity monitor in FCPX and in AME. Both drives have high read/write speeds. The drive where footage is located is spinning at 500MB/s ish and the target drive is spinning at 800MB/s +

Really odd. Its the export from FCPX from red raw files that has dropped off a cliff, no other program is suffering.

Any new devices added to the export buss that might be throttling speeds? I know quite a few editors who work in Red files all day and have never heard them discussing this. Only folks with huge export grief are folks who have applied one of the really pixel calculation intensive plugins like Neat Video noise reduction. Puzzling for sure!

The only difference is that last week I had an Ultrastudio 4K running from one of the thunderbolt ports (different bus to the RAID 1 and 2). As I have completed editing and just need to export 30-40 1 minute clips I've removed it to save bandwidth (and the constant fan humming).

Thanks for trying to help though Bill.

Apple have advised me to take the Mac Pro to my nearest shop and book with a genius to see if a GPU or RAM stick has gone faulty.
