Any way to Speed up Compressor?
We just recently purchased a new Mac Pro with 2 gigs of ram and 2 x 2.8GHz quad core processors – and have FCP Studio 6 installed.
We are capturing HD features uncompressed and then using Compressor to apply the bitjazz codec (https://www.bitjazz.com/en/products/sheervideo/) to them to shrink the file size down to a manageable size.
The problem is that Compressor seems to take approx. 6-8 hours to grind through each feature (approx 90 min TRT)
Does anyone have ANY advice about the best course of action to speed up Compressor? More Ram? More Processors?
when checking the activity monitor it shows the machine has around 1/2 gig of free memory and another 1/2 gig is “inactive”
The processor does’t look like its overworked either?
Is there a setting inside Compressor to enable multiprocessor functioning?
any help would be apprciated.
thanks

If you have multiple computers you can use QMaster. Read up on QMaster. Keep in mind you will need multiple FCS licenses to take advantage of it.

You don’t need multiple computers to speed up compressor, just use QMaster and set up a virtual cluster in your own computer.
It’s in System Preferences/Apple Qmaster. Select Share this computer as Quick Cluster with services. Share Compressor. Options should be 1 instance for each of 2 processors, so if you have an Octo, set it to 4 instances. Click Share…
Then when you submit from compressor, change it from This Computer to whatever you named your cluster. Works like gang busters…

Why not just capture straight to the bitJazz codec? Or ProRes?

[Travis Roop] “Is there a setting inside Compressor to enable multiprocessor functioning?”
Yes, look up info on setting up a Virtual Cluster in QMaster but you need more RAM (at least 1 GB/processor that you turned on).Could you not capture to this codec? Seems like the workflow doesn’t trust the selling points of the codec if you can capture, the real savings is if you don’t waste the space capturing HD uncompressed.

Thanks guys! I have set up a virtual cluster inside my computer and instead of 8 hours to encode its now taking around 2 amazing!
We had originally thought we could capture directly to the bitjazz sheer codec but apparently there is a bug in the codec or something that prevents you from capturing large frame sizes… so we’re capturing uncompressed and applying the codec afterward.
thanks again!Travis Roop

What capture card do you have?
-
well unfortunately the cluster I set up was saving the temporary files to the main hard drive instead of the other media hard drive, even though I had selected the media drive as the destination…
the main drive filled up and stopped my batch. I couldn’t figure out how to empty the hard drive as the temp cluster files aren’t viewable via finder! luckily our tech guy was able to delete most of the temp files so the main hard drive is back to normal size but the cluster settings have been removed and Im back to square one 🙁
I’m not sure what capture card we’re using..uh..where would I find that info?
I know we have an HD graphics card and use Black magic deck link. -
Blackmagic, that’s your card.
Sorry can’t hekp you there. A Kona can do this (capture to Sheer) but not sure about Decklink. Have you contacted Sheer? I hear the support there is good.

As Jeremy suggests you can capture directly to Sheer with the BM. You should have the Sheer’s Easy setups in FC.
However if you want to convert your HD Unc to Sheer, there is no point to do it in Compressor.
You don’t go to change field order,size, pixel aspect..only the codec.
FC will do it as good as Compressor and much faster. Don’t waist your time.

The cluster storage is defined under the Advanced tab… it defaults to /var/spool/qmaster – type ⌘-shift-G in a Finder window and put that in to get to that folder to remove old temporary files… redefine it to your media drive if you like…
