QMaster Rendering

My QT renders in QMaster are just making .iff sequences... Two scripts rendered out properly (to Animation codec), but the others reported fails from Qmaster.
A sample Qmaster report:

Any ideas on what's causing this?

I had the white frame problem on one job on segments of the movie that were done on the Mac that did not have the source media. I did a test with another file and it worked fine. What I finally figured out was that the first file was a reference movie whose data (FCP render files) wa on a volume not mounted on that Mac. The volume with the reference movie was on the volume set in Qmaster. Mounted the media volume and all was well.
Funny it just puts out white frames instead of giving you an error message.
I don't usually do reference movies for just such reasons, but this was a long, quick & dirty VHS to DVD job, not a keeper.
Good luck,
Russ

    Thanks for taking the time to read my error! This is the vain of my life right now, we have recently set up a new cluster with 20+ imac's. I understand that the error is that the macs in our cluster cant find the project directory. I have changed this to a shared folder with read and right access to our x-raid server but to no avail. Im sure that its something simple but i have not much experience with mac since changing from windows network and server 6 months ago.
    Thanks for your time for reading my post.

  • Some Problems Rendering With Maya

    Hi there! I had submitted a Maya job with my Qmaster and it worked fine with my sime animation sequence and putting up basic materials. Now, I have a quite complex scene and it includes materials and textures. Qmaster renders the animation sequence but it only gives me black and white outputs... the textures were not included!
    What seems to be the problem?

    Hi,
    I haven't used qmaster, but i have extensive experience network rendering with maya, so here goes.
    Most likely, your problem is that you are rendering across multiple machines, but the volume names are different. Your file paths must match exactly. For example, on my pc's, all of them have a y: drive. Whenever I need to network render a project, I will just use the y drive and make an exact copy of the directory on each computer. this is also the same format that the renderfarm I use. Unless you have a SAN, you will need to do something similar to this on the mac.
    If you poke around, you should be able to find a log file that will show you that textures could'nt be found (missing), and in that case, the renderer render's black.
    I am interested in qMaster since I have switched my studio over to mac's and need a good network renderer. If you can post your experience when you get a chance i would like to know how it works for you.

  • EDIT in HDV 1080i60 or CONVERT to apple pro res 422?

    Hi all --
    I'm starting a project today shot in HDV 1080i 60.  Working in fcp 7
    The client has imported MANY hours of footage into fcp at that codec in preparation for the edit.... of course, there's still alot of material
    to import including dozens of hours of h264 files shot on an SLR.
    So my question is -- should I keep the project in the hdv codec or attempt to convert everything to prores 422 before proceding?
    Is there an advantage to working in prores?
    If conversion is the answer, what is the fastest and simplest way to batch convert this material?
    Thanks in advance,
    Mark

    thanks Studio X... what is it about HDV that's so heinous?  I have to say -- some of the file sizes I'm seeing for the clips are huge.
    Is it that the HDV requires more processing power from the machine?
    Anyhoo -- I'm feeling that you're right and it might be a good idea to convert the entire project to ProRes LT.  The Qmaster rendering services -- basically that's a way to assign processing power from the cores to the compressor conversions?
    This is the beginning of the long term project and I don't want to set off in the wrong direction.  The client did a good job loading the HDV material into the fcp, but I'd feel better if we were working in ProRes -- as you suggest. 
    cheers,

  • Can I speed up final cut and motion rendering using qmaster?

    I have set up a cluster to speed up exporting via compressor, but I am wondering if I can use the same technique to speed up the rendering (not the exporting) in final cut pro, or motion (or other programs included in the suite for that matter)
    I read that you can use an xgrid cluster to do this, but I don't have a mac server to use xgrid and would prefer not learning a new program if I can stick with qmaster.
    Thanks

    Since your camera is acquiring at the rate of 1.2 frames/sec, that means a frame is ready every 833 ms. This is a function of your camera and may or may not be variable. This is the fastest possible loop rate you can achieve. With that in mind, if your image analysis takes 400ms and the motor 200ms, you still have about 233ms of time left to wait for the next image to be ready.
    Yes, by reducing the acquisition window size, you reduce the amount of data moved across the PCI bus to system memory, but the camera control how quickly frames are being sent so this will not speed up your acquistion. It will, however, decrease your processing time since you are processing fewer pixels.
    Also, a ring acquisition would be the best acquisition mode to implement since you w
    on't need to setup a new IMAQ session each time. If you are worried about not finishing a move before the next image is acquired, you can just use the Wait for Move Complete function in ValueMotion and then continue with the image acquisition.

  • Rendering FCP w/ Qmaster?

    I am using four 2.7dual G5 powerMacs and they work great together for compressing. Can I use this process for rendering sequences in FCP?

    Just got back online. Thanks for returning my post.
    Here are the specifics. We have four 2.7 G5s, all running FCP Studio, completely. Up until I started working there they were all running isolated from each other in separate editing suites. I thought that was shame so I have been networking them to share processing time. They are on a gigabit ethernet connection. I have them continually linked to the cluster controller so that the shared volume is accessible to all computers. They all have Qmaster and admin.
    In system preferences I have services only on three nodes, with the "managed" box checked on each. I have a cluster controller, also running services, and all allow use of unmanaged services. Apple talk is active on all. I tried a test run today using compressor to make a 2-pass mpeg with audio and it cut my compression time by a factor of ten. (Literally, I compressed the same file last week and it took ten hours, today it took 90 min.) So I know the configuration is set up properly.
    Here is what I don't know. I see no option for sending a render sequence file to Qmaster or compressor. In FCP you go to sequence, and then render selection, render all, or render only and then choose audio, video, or both. When I did that as usual, it just rendered as usual, using only the host computer. How can I make the cluster take the onus of the render command?
    If there is any info left out tell me. Would very much appreciate the help.
    Thanks,

  • Qmaster stopps Maya rendering after the first submitted job

    I tried to render some jobs with qmaster 2 and maya 8. Everything worked fine until the first submitted job is rendered. It seems that qmaster can't quit this first job after rendering and so the batch render stopped. Any ideas?

  • Qmaster network rendering for AE?

    I was browsing the Final Cut Studio 2 site over at Apple.com and ran into this little tidbit...
    http://www.apple.com/finalcutstudio/compressor/encoding.html
    "Qmaster uses the processing capacity of your network computers for a wide range of tasks, including encoding and rendering for motion graphics produced by applications such as Apple Shake, Adobe After Effects, and Autodesk Maya. Configure Qmaster clusters to run jobs for encoding, rendering, or both,"
    So does this mean the new FCS2 Qmaster can network render AE projects?

    Final Cut Studio 1 can network render After Effects projects. This isn't new functionality in FCS2. The biggest caveat is that each rendering node needs an installed copy of After Effects as well as any AE plug-ins used in your project.

  • QMaster for rendering Maya from Windows XP systems

    I am working on setting up a distributed rendering system for a number of different applications including Final Cut Studio apps, Shake, and Maya. We have a mixed computing environment with Windows XP systems and OS X systems. I'm wondering if anyone has any experience with Maya on Windows sending projects to the QMaster queue. Any help that you can give me will be greatly appreciated.
    Thank you,

    The GDI print sample, on which I based my repo application, is quite trivial. There can't be any confusion between the screen and a printer, because the code only targets the single device that is hard-coded in the source.
    Regarding your speculation about registry keys, are you suggesting that there might be some OS registry keys that control this? If so, it seems to me, these keys would have names and somebody would have named them by now. Or are you speculating that the application uses its own registry keys for control? Again, the application is trivial. Someone would be able to cite the source file and line number if control points like this existed in the application.
    If the source code is changed to target the XPS document writer, the box characters all line up perfectly. Doesn't that eliminate everything except the PostScript driver?
    Is there a more formal channel for reporting bugs in the PostScript driver?

  • QMaster Settings, And Freezes When Rendering From FCP

    I have a Octo Mac Pro and I setting the settings in QMaster to 12 intances, and even 8 for cluster renderings. When I tried to render a clip from FCP to Compressor, it freezes in the Batch Monitor at like 50% and stops? Has anybody else had this problem? What are the best settings in Qmaster to get good results ? Sweet spot? Instances settings etc.? for Cluster renderings?
    Thanks TimC

    See kenstone.net for some articles on the topic of optimizing Qmaster.
    But freezing usually indicates a different kind of problem, probably associated with your source movie or the amount of space on the target drive.

  • QMASTER hints 4 usual trouble (QM NOT running/CLUSTEREd nodes/Networks etc

    All, I just posted this with some hints & workaround with very common issues people have on this forum and keep asking concerning the use of APPLE QMASTER with FCP, SHAKE, COMPRESSOR and MOTION. I've had many over the last 2 years and see them coming up frequently.
    Perhaps these symptoms are fixed in FCS2 at MAY 2007 (now). However if not here's some ROTS that i used for FCP to compressor via QMASTER cluster for example. NO special order but might help someone get around the stuff with QMASTER V2.3, FCP V5.1.4, compressor.app V2.3
    I saw the latest QMASTER UI and usage at NAB2007 and it looked a little more solid with some "EASY SETUP" stuff. I hope it has been reworked underneath.. I guess I will know soon if it has.
    For most FCP/COMPRESSOR, SHAKE. MOTION and COMPRESSOR:
    • provide access from ALL nodes to ALL the source and target objects (files) on their VOLUMES. Simply MOUNT those volumes through the APPLE file system (via NFS) using +k (cmd+k) or finder/go/connect to server. OR using an SSAFS such as XSAN™ where the file systems are all shared over FC not the network. YOu will notice the CPU's going very busy for a small while. THhis is the APPLE FILE SYSTEM task,,, I guess it's doing 'spotlight stuff". This goes away after a few minutes.
    • set the COMPRESSOR preferences for "CLUSTER OPTIONS" to "Never copy source to Cluster". This means that all nodes can access your source and target objects (files) over NFS (as above). Failure to to this means LENGTHY times to COPY material back an forth, in some cases undermining the pleasure gained from initially using clustering (reduced job times)
    • DONT mix the PHYSICAL or LOGICAL networks in your local cluster. I dont know why but I could never get this to work. Physical mean stick with eother ETHERNET or FIREWIRE or your other (airport etc whic will be generally way to slow and useless), Logical measn leepin all nodes on the SAME subnet. You can do this siply by setting theis up in the system preferences/QMASTER/advanced tab under "Use Network Interfaces". In my currnet QUAd I set this to use BUILT IN ETHERNET1 and in the MPBDC's I set this to their BUILTIN ETHERNET.
    • LOGICAL NETWORKS (Subnet): simply HARDCODE an IP address on the ETHERNET (for eample) for your cluster nodes andthe service controller. FOr eample 3.1.1.x .... it will all connect fine.
    • Physical Networks: As above (1) DONT MIX firewire (IPoFW) and Ethernet(IPoE). (2) if more than extra service node USE A HUB or SWITCH. I went and bought a 10 port GbE HUB for about $HK400 (€40) and it worked fine. I was NEVER able to get a stable system of QMASTER mixing FW and ETHERNET. (3) fwiw using IP of FW caused me a LOAD of DISK errors and timouts (I/O errors) on thosse DISKs that were FW400 (al gone now) but it showed this was not stable overall
    • for the cluster controller node MAKE SURE you set the CLUSTER STORAGE (system preferences/QMASTER/shared cluster storage) for the CLUSTER CONTROLLER NODE IS ON A SHARED volume (See above). This seems essential for SHAKE to work. (if not check the Qmaster errors in the console.app [see below] ). IF you have an SSAFS like XSAN™ then just add this cluster storage on a share file path. NOte that QMASTER does not permit the cluster storage to be on a NETWORK NODE for some reason. So in short just MOUNT the volume where the SHARED CLUSTER file is maintained for the CLUSTER controller.
    • FCP - avoid EXPORT to COMPRESSOR from the TIMELINE - it never seems to work properly (see later). Instead EXPORT FROM SEQUENCE in the BROWSER - consistent results
    • FCP - "media missing " messages on EXPORT to COMPRESSOR.. seems a defect in FCP 5.1 when you EXPORT using a sequence that is NOT in the "root" or primary trry in the FCP PROJECT BROWSER. Simply if you have browser/bin A contains(Bin B (contains Bin C (contains sequence X))) this will FAIL (wont work) for "EXPORT TO COMPRESSOR" if you use EXPORT to COMPRESSOR in a FCP browser PANE that is separately OPEN. To get around this, simply OPEN/EXPOSE the triangles/trees in the BROWSER PANE for the PROJECT and select the SEQUENCE you want and "EXPORT to COMPRESSOR" from there. This has been documented in a few places in this forum I think.
    • FCP -> COMPRESSOR -> .M2V (for DVDSP3): some things here. EXPORTING from an FCP SEQUENCE with CHAPTER MARKERS to an MPEG2 .M2V encoding USING A CLUSTER causes errors in the placement of the chapter makers when it is imported to DVDSP3. In fact CONSISTENTLY, ALL the chapter markers are all PLACED AT THE END of the TRACK in DVD SP# - somewhat useless. This seems to happen ALSO when the source is an FCP reference movie, although inconsistent. A simple work around if you have the machines is TRUN OF SEGMENTING in the COMPRESSOR ENCODER inspector. let each .M2V transcode run on the same service node. FOr the jobs at hand just set up a CLUSTER and controller for each machine and then SELECT the cluster (myclusterA, hisclusterb, herclusterc) for each transcode job.. anyway for me.. the time spent resolving all this I could have TRANSCODED all this on my QUAD and it would all have ben done by sooner! (LOL)
    • CONSOLE logs: IF QMASTER fails, I would suggest your fist port of diagnosis should be /Library/Logs/Qmaster in there you will see (on the controller node) compressor.log, jobcontroller.com.apple.qmaster.cluster.admin.log, and lots of others including service controller.com.apple.qmaster.executorX.log (for each cpu/core and node) andd qmasterca.log. All these are worth a look and for me helped me solve 90% of my qmaster errors and failures.
    • MOTION 3 - fwiw.. EXPORT USING COMPRESSOR to a CLUSTER seems to fail EVERY TIME.. seems MOTION is writing stuff out to a /var/spool/qmaster
    TROUBLESHOOTING QMASTER: IF QMASTER seems buggered up (hosed), then follow these steps PRIOR to restarting you machines.
    go read the TROUBLE SHOOTING in the published APPLE docs for COMPRESSOR, SHAKE and "SET UP FOR DISTRIBUTED PROCESSING" and serach these forums CAREFULLY.. the answer is usually there somewhere.
    ELSE THEN,, try these steps....
    You'll feel that QMASTER is in trouble when you
    • see that the QMASTER ICON at the top of the screen says 'NO SERVICES" even though that node is started and
    • that the APPLE QMASTER ADMINSTRATOR is VERY SLOW after an 'APPLY" (like minutes with SPINNING BEACHBALL) or it WONT LET YOU DELETE a cluster or you see 'undefined' nodes in your cluster (meaning that one was shut down or had a network failure)..... all this means it's going to get worse and worse. SO DONT submit any more work to QAMSTER... best count you gains and follow this list next.
    (a) in COMPRESSOR.app / RESET BACKGROUND PROCESSES (its under the COMPRESSOR name list box) see if things get kick started but you will lose all the work that has been done up to that point for COMPRESSOR.app
    b) if no OK, then on EACH node in that cluster, STOP the QMASTER (system preferences/QMASTER/setup [set 0 minutes in the prompt and OK). Then when STOPPED, RESET the shared services my licking OPTION+CLICK on the "START" button to reveal the "RESET SERVICES". Then click "START" on each node to start the services. This has the actin of REMOVING or in the case where the CLUSTER CONTROLLER node is "RESET" f terminating the cluster that's under its control. IF so Simply go to APPLE QMASTER ADMINISTRATOR and REDFINE it. Go restart you cluster.
    c) if step (b) is no help, consult the QMASTER logs in /Library/Logs/Qmaster (using the cosole.app) for any FILE MISSING or FILE not found or FILE ERROR . Look carefully for the NODENAME (the machine_name.local) where the error may have occured. Sometimes it's very chatty. Others it is not. ALso look in the BATCH MONITOR OUTPUT for errors messages. Often these are NEVER written (or I cant find them) in the /var/logs... try and resolve any issues you can see (mostly VOLUME or FILE path issues from my experience)
    (d) if still no joy then - try removing all the 'dead' cluster files from /var/tmp/qmaster , /var/sppol/qmaster and also the file directory that you specified above for the controller to share the clustering. FOR shake issues, go do the same (note also where the shake shared cluster file path is - it can be also specified in the RENDER FILEOUT nodes prompt).
    e) if all this WONT help you, its time to get the BIG hammer out. Simply, STOP all nodes of not stopped. (if status/mode is "STOPPING" then it [QMASTER] is truly buggered). DISMOUNT the network volumes you had mounted. and RESTART ALL YOUR NODES. Tis has the affect of RESTARTING all the QMASTERD tasks. YEs sure you can go in and SUDO restart them but it is dodgy at best because they never seem to terminate cleanly (Kill -9 etc) or FORCE QUIT.... is what one ends up doing and then STILL having to restart.
    f) after restart perform steps from (B) again and it will be usually (but not always) right after that

    Warwick,
    Thanks for joining the forum and for doing all this work and posting your results for our benefit.
    As FCP2 arrives in our shop, we will try once again to make sense of it and to see if we can boost our efficiencies in rendering big projects and getting Compressor to embrace five or six idle Macs.
    Nonetheless, I am still in "Major Disbelief Mode" that Apple has done so little to make this software actually useful.

  • I need to know best way to edit MXF files, with least rendering, is that converting the MXF or Log and Transfer? the end product is dvd, but I have lots and lots of these projects to do.

    I am about to comence my Edit, and was told of Mpeg Streamclip, however this doesn't seem to work with my Canon XF305 Clips, the reason I was told to use it was so I wouldn't have to Render in Final Cut Pro all the time.. I do have the Canon Disc with the Plug in Utility and the update from their site.
    Is it best to Convert these MXF files first and import them into FCP or use 'Log and Transfer', so far I am unable to do either!!
    The projects on the timeline will have introduction .Movs already on it as a Template to re-use again and again with the new Footage ( MXF Files ) to be added and edited with transitions etc..This process is repeated again and again but with different MXF clips each time.
      I am looking for the quickest and best way for workflow as there are 80 or more projects to do, each with 10 or so clips to be added to the timeline and Exported for DVD...Will I have to then Compress to fit onto DVD's??
    I know Streamclip is an Mepeg 2 app but I thought the Canon XF305 Shot as mpeg2....
    Is Log and Transfer my only Option?
    Basically I need to know the quickest for Render purposes, and of course, the best way so the files aren't so huge etc etc.
    Please, any suggestions would be greatly received....

    We only work with PR422 files in FC7.  We use Shane's workflow with all 5D & MXF footage.
    Make your life easier and stick to the ProRes family for your footage and edit sequences. Avoid H264 & convert any you have to ProRes.
    Unless you are considering Blu-Ray the only way to deliver video on a DVD is to convert it to SD.
    Depending on the length of your show you can make a Blu-Ray in Compressor but you have very limited authoring options when compared to DVD Studio Pro.
    Compressor can also convert your HD to SD mpg-2 & Ac3 files. The best results usually come from setting the frame controls in the mpg-2 setting of Compressor to best. Depending on the the length of the show and your Qmaster settings this can take quite a while.
    I personally find Compressor's HD to SD DVD conversion varies. Sometimes it is wonderful and sometimes not so much. I prefer the following as it is usually is faster and very consistent.
    Export a quicktime movie (not QT conversion) of your final sequence
    Import the exported HD file back into FC.
    Create a SD 16x9 sequence and then drop in the recently exported HD seq and render. Rendering the sequence basically has FC doing the HD to SD conversion. Export the SD sequence and then convert to mpg-2 & ac3 in Compressor. While this does take time I still find it faster than Compressor with Qmaster utilizing all cores.
    Another option is using jobs in Compressor
    http://pixelcorps.cachefly.net/macbreak-154-540p-h264.mov
    In this workflow you would have Compressor convert the HD file to SD and then through jobs convert the SD file to mpg2 & Ac3. 
    In theory the jobs version could be faster (based on a number of variables- length, Qmaster, etc) but I haven't had time to compare the two. 

  • Qmaster actually make a performance difference thats NOTICEABLE??

    I have Apple Qmaster 2.3.1 installed on a Dual 2.7 Powermac and an i7 new intel based Macbook Pro. The FCP Suite is all installed on the PMac Tower, and Compressor doesnt allow you to use the same serial on a second computer in the network (the doc. doesnt state it MUST be on all machines, only the Qmaster).
    I tried this setup with an ethernet cable as well as with Airport networking (computer-to-computer setup, no firewall turned on, internet access turned off for security)
    According to the "getting started quickly" segment of the 'Apple Qmaster and Compressor 2' pdf that came with my FCP Suite, I have installed it correctly.
    I can see and submit to the cluster that is originated on the Powermac, see the active service (Compressor cluster only allows one core of the Macbook Pro to be used according to documentation, and sadly only 3 kinds of render software can make use of all 4 but NOT ANY compressor or FCP rendering? LAME... or please correct me if Im wrong)
    I did a transcode of resizing and change of codec and timed it using just This Computer first then through the cluster....
    over a 22 min. encode in both settings, there was barely a difference of 5% between the trial encodings... is this thing actually working? is there a BETTER way to test the cluster to see if I actually would benefit keeping the laptop in cable length of the tower? (ie: is there a verifiably FAST encoding I could try to see ANY difference; .mov to .mpv or something?)
    I then downloaded and tried to do a cluster using Pooch but that breaks shortly after submission with an app crash... so that cant even get any performance vector to compare with Qmaster....
    Seriously... if a 5 to 10% increase in encoding speed is what Apple thinks is QUALITY performance, when using a virtual 6 chip system via Qmaster, I am underwhelmed... therefore Im thinking something must be wrong instead. Tested the cable with a high bandwidth video iChat and a few things, seems to have no prob with throughput, so cable doesnt look like the culprit.

    Well on the i7 it also had its firewall turned off (hoping this opens all available ports by doing this), had the setup of the prefs pane of Qmaster set to 'services only' as per the client/cluster rules in the guidelines, had the Managed settings turned 'off', the Network choice under the Advanced tab set to All Interfaces and a working cable confirmed by doing a machineToMachine test of conductivity by making an iChat audio/video connection.
    On the client machine (tower, serving the submission to the cluster) the setup was the same only with the prefpane set to Quickcluster with services, Services with Managed unchecked, Quickcluster option set to 'include unmanaged services from other computers', and the rest all identical settings.
    I just heard a Pick Our Brains on DP Buzz podcast that said H.264 does not multithread, which maybe effecting things even if transcoding to a different size (RE: re-encoding perhaps after resizing?), so maybe I will try a QT file output using x264 codec which the author loosly is suggesting IS multithreading (dunno but will try)
    Further more, I re-read the manual and on pg. 15 it is conflicting: "NOTE: the compressor 2... limited to computers that have either FCP Studio or DVDSP 4 installed". well, not possible without multi license release as it checks and warns you if you try installing the same software using the same license number... also is conflicting the message later on in the install instructions (below)
    Later on the same page the restrictions are different...: "Each computer in the network will require Apple QMaster AND/OR Compressor 2...", then again muddled on pg 16 (installation) by saying "make sure the client software (meaning qmaster I think) is on atleast one computer" and further on down "software (either Compressor or Apple Qmaster"
    SOOOOOO, what I gathered by the majority of the conflicting specs is that ONE machine should atleast have ALL the FCP and Qmaster installed on it, and the rest atleast have Qmaster installed... when it says either/or, I went with the 'or' boolean meaning I was allowed only to install Qmaster without the installer warning me about things.
    (I am not doing Dolby D. Pro audio so I dont have to install FCP/DVDSP as a result thankfully...because I dont see buying another license just to test out improved cluster processing)
    Wouldnt mind knowing if anyone found Pooch to be a better solution, and more flexible as it supposedly will work with a number of processes let alone with a QT codec for exporting a number of different formats... anyone try Pooch with their iMovie or FCP or DVDSP?

  • Using Qmaster with DVD Studio Pro OR Qmaster requires FCP on all machines?

    Greetings everyone,
    After a few days of tinkering I've finally managed to set up a managed cluster. However, I have a problem (surprise, surprise). When I submit a job to the cluster, Final Cut Pro suddenly opens up on all of the computers being used. I have Final Cut Studio 2 under an academic license, and all copies report that there is another copy running with the same serial number and that they must shut down. They render a few frames before suddenly quitting the job, regardless of whether I leave the message up or OK it away. I've done some reading from this thread which makes it sound like all systems must have a copy of FCP installed, or to use a slightly different method:
    http://discussions.apple.com/thread.jspa?threadID=375923&tstart=195
    It's a bit upsetting as I'd originally read that systems could aid in rendering with just QMaster installed, and that they didn't need FCP installed. Hence, having FCP open up was unexpected, and I get the feeling that uninstalling FCP from those systems wouldn't help me.
    But let me explain what I do normally, and perhaps some of you can guide me.
    My work has me converting hundreds of tapes to DVD. Without QMaster, I would import the videos in Final Cut Pro, set chapter markers and in and out points, and then export the video (with barely any processing - an export typically takes 4 minutes on a dual 800 Mhz G4). I'd then import it to DVD Studio Pro, handle the menus, and then do a build and format. That process would take ~2-3 hours per DVD, and that is the part that I'd like to optimize.
    The setup is such that I have one dual G5 wired to our hard drives (all Firewire 800), and then four other systems that connect to the G5 to access the HDs through a gigabit network switch. This has worked quite nicely in that it allows systems that only have Firewire 400 to work at Firewire 800 speeds regardless.
    I'd originally thought that DVD Studio Pro 4 would automatically be able to process jobs through Qmaster, but I couldn't find a setting for it and it didn't seem to do it on its own. Instead, I was planning to redo my work flow such that the encoding of the video (the most time-consuming part of DVD Studio Pro's build procedure) would be done in Final Cut Pro. Or more specifically, it would go through Compressor. However, as I mentioned above, attempting to work this way causes Final Cut Pro to open up on all nodes within the cluster. As they all have the same serial number, they become unhappy under such conditions. I can uninstall them from the systems as I only ever use one copy at a time anyway, but as I mentioned from the link above, it seems that rendering through FCP -> Compressor will require FCP to be installed on all participating systems.
    Does anyone have any advice for what to do? Is there a way to get around having FCP activate on all participating systems, or is there a way to do it directly through DVD Studio Pro (ideally in a manner that wouldn't cause DVD Studio Pro to activate on all participating systems)?
    Any advice is much appreciated. The distributed encoding is really the only reason why we upgraded to Final Cut Studio 2, so I'm going to feel rather foolish if this doesn't work out.

    A QCluster network isn't designed to distribute Rendering from FCP, rather it's designed to distribute encoding tasks.
    As mentioned in that thread you linked to, the best workflow I can think of in your situation is to export Quicktime reference movies from FCP, then bring those reference files into Compressor for distribution to the QCluster for the transcode to MPEG 2 for DVD. There is a wealth of good information in that thread.
    In short, if you attempt to use a Cluster to export from FCP, then all of your nodes will need to have separate licenses of FCP. But if you use the reference movie method, FCP is not required for the encoding.
    One question for clarification with your workflow, are you logging & capturing these clips then sending them directly to DVD? or are you editing them in a timeline prior to export to DVD?
    If you're just using FCP as your Log & Capture tool, then you can skip the reference movie step and just grab the captured clips in your Capture Scratch folder and send those directly to Compressor.

  • Is there a recommended maximum number of jobs QMaster can handle?

    In our setup we need to render some 4,000 - 8,000 short video segments (only a few seconds each). Right now we are submitting them all one after the other via the command line to a cluster (QAdministrator has been set to allow 10,000 batches in the queue).
    Has anyone experienced problems with queues this large? When rendering, QMaster randomly dies - mostly at around 1,000 batches. The batches remain in the spool but I need to reinstall the QMaster Service Node package to get everything off and running again.
    I don't like the idea of having to babysit the queue and I submitting the next one after the previous one negates the whole idea of using clusters.
    I've thought about adding more equipment to clear out the queue faster, but I don;t want to recommend this route if it doesn't work as that would be a huge expense wasted.
    It's almost as if QMaster has a memory leak but that's just a guess.
    Any thoughts or wisdom would be welcome.

    I would imagine most people submitting such a large number of jobs are using something more robust like Qube:

    Qmaster is very buggy and would need a complete rewrite before it could be qualified for use in such an environment.
