Hi all,

          I've been pulling my hair out for the last 2 days struggling to get QMaster to work within Compressor 4. Here's my current set up:


Macbook Pro 17' i7 2.4Ghz, 16 GB RAM with a 512GB SSD HD - This should be a pretty good set up for laptop processing???


Within Compressor 4 I select 'share this computer'

- Share as QuickCluster with services ON

- Services; Compressor ON

- Number of instances; I've chosen everyone from 1-4. It gives me the option for 8 can my computer handle 8?

- Require these services only to be use in managed cluster ON (i've tried it selected off and still no joy)

- QuickCluster; Named my QuickCluster

- Include unmanaged services from other computers ON


When I hit submit I can't select my named Cluster. Only 'This Computer'


In Share Monitor I can only see one cluster. I've read many posts saying that you should be able to see the multiple cluster setup.


In Activity Monitor Compressor is using 344% and The CPU overall is saying only 44% used by user???


Ive followed so many instructions on the internet but still no visible joy.

    Hi Reelsick (love your business name!). HELP IS ON ITS WAY (Little River Band 1979) This symptom is easy to rectifiy. NO NEED for any third party apps and nothing to do with itself.


    Simply you need to REMOVE all the QMASTER state information.


    Here's a detailed link at ... look at the 3rd post down... detailed instrucrtions/procesure.. easy.


    Basically is you remove | purge | delete all things in ~/Library/Application Support/Apple Qmaster/ after you have shut down QMASTER , QMASTER will restart ok


    BTW.. theres loads of tips on this on these forums however there is NO NEED at all for any 3rd party apps, nor resinstallation of compressor  nor messing with prefs.. yeah it may have helped some but the issues is qmaster.


    Try these procesures at , it usually works for my colleagues and myself.


    Oh btw, you might find more responsive when adding a batch if the PREVIEW window is closed. Simply it seems to avoid building a oeview and submission is faster for a lot of jobs.. (old R.O.T but worth mentioning).

  is great.. just need to coax it a bit.


    Post your results for others to see.

    Thanks for the reply. So i followed your steps.... But i still can't see the customized cluster i named. It just says 'this computer' in the drop down menu.


    If i Control+Click on the compressor icon I can see 8 Qmaster services...


    Am I getting close?

  • Reelsick Productions Level 1 (10 points)

    Ok So now I have 3 clusters named This Computer... ahhhhhh which one? Any of them?

    In Compressor make sure 'Allow Job Segmenting' is check. If it not checked this will not work.

    If you are not sending the finial video to the web turn off fast start. Streaming: None




    Compressor Menu---> Apple QMaster---> Share This Computer.

    Screen Shot 2013-02-25 at 4.12.02 AM.png

    Notice that under QuickCluster the identifying  name is Dave's. You'll select this when submitting the job in Compressor. (Your name will be different.)




    Click on the Compressor options button to bring this widow up.

    I have a 27" i7 4 core iMac. 4 cores = 8 Threads. So I set this to 4 instances. I can go up to 8 but, this doesn't add to the speed when rendering the job. In fact this can add time to the rendering time.




    Submitting the job:


    Click the Sumit button--->


    Screen Shot 2013-02-25 at 4.36.37 AM.png

    From the drop down menu pick the QuickCluster identifier name that I mention above.


    ________________________________________________________________________________ __


    Open the Share Monitor window.


    Screen Shot 2013-02-25 at 4.41.37 AM.png


    Click on the QuickCluster name to see the rendering process. Done.




    This is how I use the Activity Monitor App to see how the computer is processing the video.


    Screen Shot 2013-02-25 at 4.46.18 AM.png


    Activity Monitor Menu---> Window---> CPU Usage window (and pick to keep this on top).


    You'll have 4 compressord open. I usually get around 180% CPU usage per compressord. The 5th one is for 'This Computer' and won't be used.

  • Reelsick Productions Level 1 (10 points)

    Well I've just selected one of the clusters named This Computer (can't remember which one I chose but user CPU activity is up from 40%-70%. And i now can see 8 CompressorTranscoderX processes in the activity monitor.


    If I adjust the number of instances do i have to trash my preferences again?


    Thanks for all your help

  • David M Brewer Level 6 (9,355 points)

    Click on the Rendering button in the Qmaster window. Remove all but one 'This Computer' from the window.

    are you usiing MANAGED clusters or a simple quickcluster? IF the former, just go in to Qmaster and purge (remove) all the clusters then simply define a new custer controller and add the nodes.


    2) you can simply adjust the number of instances through  menus Apple Qmaster/share this computer/setup tab.


    1. stop qmaster "untick "share computer"
    2. adust the instances form hte list box near "compressor"a
    3. start qmaster again "TICK shre thsi computer"


    ALso a good tip form DAve about job segmenting. Also unless you need to make syre that FRM CONTROLS is set to OFF. Some people have their default apple presets to INITIATE FRAME CONTROLS.. thisis very CPU intensive.. loke seriously intensive and will prolong the job's elapsed greatly... simply turn it off for that job in the inpsector


    oh lastly,, just note that sometime the STATUS displays foro SHARE, and Qmaster etc may be slow. Its all socket driven and get a bit confused at times. You'll see loads of whinging in the /var/logs. by them both. You will see this also exhibited in eth HISTORY UI of yep it gets out of whack. GLadly it does right itself after time.


    post your results for others to see.



  • David M Brewer Level 6 (9,355 points)

    CompressorTranscoderX is basically the same thing as compressord. I have Compressor 3.5 and that maybe the reason my CompressorTranscoderX is named compressord.


    You should only have 4 CompressorTranscoderX. Change your instances to 4 if you have a 4 core computer. Each video segment will use 1 core and 1 hyper-thread. If you have 8 instances chosen. The video will be broken up into 16 segment. It will take more time to join the 16 segments together compared to 8 segments.

    Just a quick comment to add to the excellent help you're getting.


    Over time, everyone's system becomes unique in some important way – even if we start out buying precisely the same model, OS, and so forth. And so we should not be surprised when seemingly identical symptoms end up requiring somewhat different fixes.


    In my case I've got one foot in the FCS environment and the other in the FCPX environment. By and large, both C4 and C3.5 coexist nicely and the results I get are predictable. That's no small thing because they are essential and are used just about every day.


    But…every now and then (perhaps a couple of times a month) my Quick Cluster will go missing; it simply won't be available as an option…or even more disconcerting, I'll see the dreaded None in the Submit dialogue window. Typically, if C4 gives me None for cluster options, C 3.5 will be affected as well…perhaps offering This Computer but no QuickCluster option – and so forth.


    I'm not a real tech-savvy guy so my reponse to these "surprises" has been developed over time by trial and error. With both versions, I start by shutting down sharing – from the Qmaster menu in C4 and from Systems Prefs in the case of C3.5. Then I  close out C, reopen and start up Sharing. Often I have to close and re-open the application once more to get everything working as it should. This usually works, although I've had some occasions where I had to use Digital Rebellion's Compressor Repair. It's a great tool and I've often recommended it to others who are having Compressor-Qmaster issues.


    So I guess I'm doing more or less what Warwick was suggesting.


    And to David's explanation of TranscoderX terminology, here are rwo screen shots in AM of the same segmented job – one in C3.5 amd the other in C4.

    Good luck.



  • Reelsick Productions Level 1 (10 points)

    IT BLOODY WORKED!!!!!!! User CPU is at 98% with 4 Instances selected. It seemed to help when i changed my cluster name to a shorter name. Just need to find the right balance of instances.


    I have a macbook pro 17'' i7 2.4Ghz with 16GB of Ram.


    Thanks all

    That's great. But which step made the secret sauce?



  • David M Brewer Level 6 (9,355 points)

    I have test all combination for how many Instances to choose from and 4 is about the right number.


    When you say 98% for your CPU usage. Are you saying 98% for the total CPU usage? Or for 98% for each CompressorTranscoderX process.  98% is right for total CPU usage. 98% for each CompressorTranscoderX process is to low.  If so,  codec are you transcoding too?


    If you have this widow open in the Activty Monitor. Are all 8 indicators pegged out?


    Screen Shot 2013-02-25 at 12.18.14 PM.png

    and  this...




    If you are looking at this...


    Screen Shot 2013-02-25 at 12.28.10 PM.png


    and reading 98%. It is the same as my example above... this is correct too. All of this indecates that the Qmaster is doing it's job and working correctly.


  • David M Brewer Level 6 (9,355 points)

    My computer specs...


    3.4GHz Quad-Core Intel Core i7

    16GB 1333MHz DDR3 SDRAM - 4x4GB

    2TB Serial ATA Drive + 256GB Solid State Drive

    AMD Radeon HD 6970M 2GB GDDR5


    Basically the same as your.

    A combination of Warwick Teal and David M Brewer

    So stoke its finally working.
