FCP 5 unbelievably slow to compress video on Mac Pro hardware.

Hi -
I am compressing some HD video to H.264 format on a Mac Pro...
The version # is 5.04 - Not the Universal version which I just discovered needs to be crossgraded to. But that is a different topic.
I have about 22 minutes of video which seems to take anywhere from 2 to 5 hours to compress to the MP4 format. The machine claims that 2.6 out of 4 processors worth of processing is going on... Perhaps this is just an artifact of the emulation of the PPC hardware/software... But - yuck.
I opened the process window for the Final Cut Pro Process and it showed a zillion faults.... And then I sampled the process and ended up with a thread listing as such...

Any ideas - can this be improved? Or am I going to have to wait for the new 'discs' to arrive.
Thanks,
Dan

What Brian said. FCP will not run well, if at all, under Rosetta. It certainly won't give you any where NEAR the potential of your Mac Pro. I have friends with your system setup and they can't believe how fast it is...

  • Premiere Pro CC continuous crash and extremely slow renders on a new Mac Pro.

    Hello,
    recently we changed our editing machines with the new Mac Pro with this configuration:
    - CPU 3,5 GHz 6 core Intel Xeon E5
    - 32 GB RAM
    - 2x AMD FirePro D700 6 GB
    we work on a server connected to the Mac Pro in Dual Ethernet configuration.
    The rendering of a sequence at 1920x1080 with 3 video tracks (video footage converted at ProRes 422 LT, a title on a linked After Effects Comp and a PSD graphic overlay of a small logo) of the length of about 3 minutes it takes about 4 hour... when it doesn't crash.
    When it crash, usually when i simply scroll the timeline, i receive an error message very long (if you want I can send you a rtf file about it, it's too long to paste it here).
    These are my system information:
    - Premiere Pro CC 8.2.0 (65)
    - I've installed every updates available at this time
    - OS X Yosemite 10.10.2
    Thank you very much in advance, and sorry for my bad english.

    Thanks Andrea for your assistance in reporting that additional information. You have come across an intermittent bug which has been reported by other users with no reliable repro steps for us to follow in house. So it appears to be mainly system specific, but we're not even sure which sorts of systems demonstrate it yet.
    One other thing to try is clearing your media cache files (from preferences > media panel). In the meantime,e the best thing to do is make sure you submit those crash logs to adobe whenever you get them. This helps us identify common thread among various users who may be experiencing the same problem. Also, if you have time, please file a bug report describing the steps that caused the issue in your case: http://adobe.ly/ReportBug
    Please be as specific as possible when describing your steps. Without a repeatable case, a bug like this is very, very difficult to fix. Thanks again for your support.
    To work around the sloe render for AE comp problem, please try right clicking on the comp in the timeline and then choose the "Render and Replace" command to transcode it out to a more easily handled format. This should help a lot with your performance slowness, and you will still have the ability to restore the original comp files if needed.

  • Premiere Pro running slow with Quadro 4000 on Mac-Pro

    Hi Forum, I could really use some help.
    I recently upgraded to CS6 abnd have been having major speed issues in Premiere Pro ever since. At the time I was running with an ATI Radeon HD 5870 1GB and using CS5.5 with no issues.
    After installing CS6 my Premiere Pro projects just slowed to a crawl. After doing some hasty research online i "upgraded" to the Quadro 4000 for Mac. It made the applications usable but still frustratingly slow. Exporting projects either directly from Premiere Pro or through Media Encoder is 2-3 times slower than before. I'm ready to ditch CS6 and go back to CS5.5 if necessary as it is serioulsy impacting my productivity.
    Any advice on fixing this issue would be greaty appreciated. Hardware, work-flow, software recommendations? I'll take it all!
    I also use two Mac monitors (only one of which is hooked up as I am awaiting the arrival of a converter to hook the second to the DVI-I) and would like to use 3 but I cannot run the ATI card at the same time as the Quado as there are only two power supply sources in the mac-pro housing.
    My projects typically look like this:
    Project Settings:
    Quicktime DV NTSC
    Codec: DV25 NTSC
    720x480
    Raw sequence:
    4 video tracks where I'll align my different camera angles to their correct time markers.
    MTS Format 1080p
    Multi-cam Equence:
    Camera edits from the raw sequence:
    Effects Sequence:
    Layers for on screen graphis, music etc.
    1 Voice track
    2-3 music tracks (mp3)
    1-2 photoshop layers
    effects track (black video fade in and out perhaps, sometimes I'll have a timer sequence dropped in here for on screen countdown).

  • Mac Os 10.6.8 Crash and video freeze, Mac Pro

    Hi,
    I just installed Mac OS 10.6 on my old Mac Pro, early 2009 (8 gib of Ram installed). I still have my old Mac OS10.5.8 on another internal boothable disk.
    It went well the first day or so but now I'm experiencing some major video problems: picture of the desktop keeps freezing, videos are crashing in Firefox 30 with Flash 14 plugin, etc. I have 2 internal identical video cards and 2 separate monitors (NVIDIA-GT120). Here is a picture of what's happening:
    I have installed upgrade for FireFox and Flash Player plugin 14.
    I've tried to deactivate Flash option for "Accelerated": nothing is changing, the problem is still there.
    Everytime a have a window that I move from one monitor to another smear and freeze all over on both monitors.
    I have QuickTime 7 and QuickTime for mac OS 10.6. I want to keep my older version because I have Quicktime Pro.
    Where should I start, I'm no expert, thank you in advance to explain it  to me in a simple manner if you answer to that post.
    Please help,
    Thank's!

    Thank you for answering so promptly,
    I already made a backup with TimeMachine of my new and original files of Mac OS 10.6 system.
    May I point out that I've just installed Mac Os 10.6 as an upgrade of  Mac OS, from 10.5. I have now Mac OS 10.5 on one boothing disk and Mac Os 10.6 on another boothing disk. I can wether rebooth on one or the other. I upgraded to my new Os from a clone copy of 10.5 to 10.6 on a different disk: I'm aware that my new Mac OS may be not be as clean as it should be.
         I also did all the operations you where mentionning such as disconnecting all non essential peripherals (even my main monitor) then power it up again. I also reboothed in "Safe Mode" and started again in normal mode afterwards. I've even zapped the "P RAM". I even did a "Repair Permissions with "Dislk Utilities". Nothing of that nature have resolved the various issues that I metionned in my previous Post.
    "Isolating an issue by using another user account"
    Thank you for the link, I shall read it carefully and thoroughly. Yes, I have tried to logged-in as a new user before your Post. I  think this solution helped afterwards.
        I don't use these options often, I'm the only user and I'm not that familiar with all these options. I've tried to share some folders or files and also tried to setup an automatic password but I was not that very succesfull. As this article is mentionning: the main idea is to "check if  the Mac OS is behaving as expected" in a new user account.
    The answer to that is a positive "yes" and I did regain a better control of my Mac OS new system afterwards.
    I did not understand at first your expression "If Back-to-My Mac is selected in System Preferences, the Guest account will not work". Reading a little about it, I think it has to do with an "iCloud feature to set up a network of Mac computers that you cant then access remotely". I don't have an iCloud connection/account installed/set-up. I only expremimented with that option once or twice many years ago with my iPod so, I,m not familiar with that option.
    "Deleting/disabling the third party applications after a restart by using the application un-installer"
    Since I'm not a newbie on the Mac, I know how "Third Party's Applications/utilities" may really mess up an OS and make it behave in unusual ways sometime... I did find some of them installed in the menu that where messing up my new Mac OS. I deleted/deactivated them completly and reinstalled them one by one, carefully reboothing my Mac between each new installation. Some upgrades where installed for some.
    Question about User Account vs. System's Files
    Can I delete certain presets and/or preference files only stored in my "User Account" but should I never do this with files stored in the "System Folder" or the "Main Library"? Sorry, I'm an "Older Guy" and I'm used to older versions of Macs... Thank you for suggesting any good updated documentation on that matter.
    Which Quicktime to use with mac OS 10.6: 7.6.6 or 7.7?
    This is not clear at all on Apple's Web Site. I've downloaded and installed both. Maybe this is my problem. I wish Apple would more clear about it for those like me who want to use Quicktime Pro: 7.6.6 for Mac Os 10.6 and 7.7 for Mac Os 10.5???
    As for now...
    My system is behaving better and it' also much more stable now, thank you! All the suggested steps have been made to to resolve certain issues.
    But not all...
    I've still have the problem with QuickTime 7 and Flash 14 plugin when I browse and watch certain videos on the Web after a certain time. It's still very annoying when it's starts: I get an all smeared up display of my desktop afterwards (as shown in the above example in my first post). Restarting my Mac resolve's it for a a while only... It seem's that there's a problem with the Video Ram stored when Quicktime/Flash 14 are used? They freeze the System's process who is trying to erase the old data and prevent's it to replace/refresh it with new data on screen...
    Thank you for your time and looking forward to read you,

  • No video on mac with hardware accelaration enabled

    hi there, i just posted this thread yesterday in the flash player category, but i think it might be more correct if its posted here. we are creating a live stream  with a digital rapids encoder, and getting no video on macs if the  hardware accelaration is enabled. we have also on demand videos which  are encoded over a main concept codec without this bug.
    so  now my question. is it possible to disable the hardware acceleration  from within flash or does anybody have similar experiences?

    Hi, I can only supply some information of the options the end user would have on Hardware Acceleration. From what I have read is that even though Adobe Flash Player has included the Mac to be able to use this, Apple may have only allowed it to function on certain Mac and iMac editions. So the end user can turn the H.A. off if it is causing issues with Videos etc. Also with the Flash Player version 10.1.82.76 the H.A. is turned ON by default, hence the option of turning it off. Now if a Mac user wants it on, or even those using other operating systems, it is also recommended to update the video and graphic drivers to the latest versions.
    From your end as to what you do I have no idea since this is the Flash Player forum and just speaking for myself, I have no experience with what you do.
    Perhaps the Flash Forum would be helpful or one of the Adobe Forums for the particular Adobe Program you use.
    Thanks,

  • Slow render speed with new Mac Pro / NVIDIA 8800

    I bought a new Mac Pro to replace a dual G5 because I have a number of Motion projects to finish quickly. My local dealer recommended the NVIDIA 8800 as it has 512 mb RAM (versus 128 on my old machine). I'm finding that the render time is worse than with the G5. I have yet to successfully render a 1 minute segment using Compressor (I've left it to run overnight several times with no success).
    In Activity Monitor I'm seeing this message: CompressorTranscoder (Not Responding). But none of Batch Monitor, Compressor or Motion are unresponsive - not indicating any hung applications.
    I've read that version 10.5.5 has compromised the NVIDIA card with Motion but haven't been able to get any reliable corroboration. As the Mac Pro shipped with 10.5.5 I can't really roll back to an earlier version.
    Any advice? Anyone with similar experiences? I'm trying to render on a new iMac with 4 GB of RAM (with the ATI 2600 video card) but it doesn't seem to be working as it is an hour in and shows at least three more hours.

  • No video on Mac Pro 266 + 20" Apple Cinema Display + ADC to DVI Adapter

    When I boot my Mac Pro, I don't get a video signal. I currently have a 20" Apple Cinema Display (clear case) connected via an ADC to DVI adapter. I have connected the monitor/adapter on a Powerbook G4 wihout any issues, which rules out the monitor. I've tried everything: resetting PRAM/NVRAM, motherboard reset button, unplugging everything...nothing works.
    Any help would be greatly appreciated!

    Are you guys using the ADC to DVI adapter or the DVI to ADC adapter?
    I have a clear 23" cinema display and I was thinking of getting a new Mac Pro... From what I can tell, you need the DVI to ADC adapter that sells for $100+. Is that correct?

  • Slow Intel 530 SSD in Mac Pro 1.1 (only write is slow)

    I Understand that SSD speeds will clock down in half since my the Mac Pro 1.1 SATA ports are 2g, but I'm still getting super slow speeds on my intel SSD. My intel SSD is clocked at around 550 read and write, which half for sata 2 should be about 250 read and write (in actual performance). The read is good at about 255, but the write is at 120s. I also have an OWC SSD, and that one is about 250 read and write, which is correct. Why is my intel SSD at 120 write instead of about 250? It has the latest firmware installed.
    im running mavericks 10.9.5 on an 8-core Mac Pro 1.1.

    OWC is not anti-TRIM. Their statements are essentially that their devices do not require TRIM.
    That is very different from what you said.
    Once you have enabled TRIM, every NEW delete you do will actually free the blocks occupied by deleted data. But to get back your performance, you need to mark more than a few blocks as TRIM-ed, then allow garbage collection to assemble them into pre-erased SuperBlocks.
    One way to accomplish this is to install TRIM Enabler on an Alternate spare system drive (any system 10.6.8 or later will suffice). Then run Disk Utility (Repair Disk) against your regular Boot drive. This produces an additional line of output, "Trimming unused blocks" and the Utility pauses for up to a minute while the block re TRIM-ed. It is very satisfying.

  • Uncompressed HD video on Mac Pro?

    I ordered my first Mac ever and will receive it in mid-September with the ATI card, 2.66 and 4 gigs of RAM. I ordered it primarily to work in Final Cut with HD video. I am confused about some of the posts I see on this forum. Will this Pro configuration be able to handle uncompressed HD, or do I need to consider a RAID configuration? If so, what type of RAID configuration is recomended? I ordered the Pro with 2x500 HD's, and just received from Newegg an additional 2 x500 HD's that were recommended on this site.
    Mac Pro   Mac OS X (10.4.7)  
    Mac Pro   Mac OS X (10.4.7)  

    You do not necessarily require RAID (0, 1 or any combination there of) for Final Cut Pro/Final Cut Studio.
    Generally speaking RAID is used for three distinct, combinable, reasons…
    1) Higher reading and writing disk access. RAID 0 will improve both and RAID 1 will improve read speeds.
    2) Redundancy. With RAID 1 implementations you get multiple original disks. This is subtely different from cloning whereas if you drestry one original in a RAID 1 set you destroy them all. Clonging is incident based so will preserve your disk state until your next clone.
    3) Larger contiguous drive sizes. Currently drive sizes max out at 750GB although with RAID 1 you can easily exceed this value into the TBs.
    If there are one or more reasons that match your needs then a RAID scheme may be for you. Be aware though there are inherent dangers (higher chances of data loss for instance) that you need to be aware of and accept/deal with when implementing such schemes. If you manage RAID correctly then every possible danger area is able to be safeguarded against. It's knowing about them in the first place.
    Personally I will be going with a 4 drive RAID 10 (RAID 1 + 0) configuration in my Mac Pro whenever it arrives.

  • MAC Pro hardware issue

    Mac Pro starts up and shuts down before loading the login screen. Any ideas what could cause this? It's about 4 years old and never gave any problems before.

    Sounds like there is a rash and run on 2008's with issues like this now.
    And SMC RESET doesn't help?
    And you have backup system disks?
    You or I or we should collect all the threads about this and 2008 and general maintenance and troubleshooting steps.
    Whether PSU, PRAM, dust, issue with incoming power that over time affects those PSUs, or even faulty graphics (2600XT, 4870, other?) and FBDIMMs do stress and age from heat when not kept cooled to below 70*C.

  • Unbelievably slow / choppy online video ...

    Hello all --
    About 3 weeks ago, I began watching "Real Time Overtime" online at HBO.com, as I do every week. It was choppy and slow, the first time that ever happened. It seemed to be buffering. Since there was no pause option on the live video feed, I would hear about 3 seconds of audio, followed by 10 seconds of buffering...then the live video would catch up and I'd miss those 10 seconds. I chalked it up to something wrong with the website. Well, over the next few weeks, I notice it happening on any live feed that I watch. Today, trying to watch the NCAA Tourney, it is laughably slow. I might get 5 seconds of play, followed by 30 seconds of delay. (insert joke here, lol/___sbsstatic___/migration-images/migration-img-not-avail.png)
    I have tried the following:
    - Updated the Software.
    - Cleared cache, history & temporary internet files.
    - Tried both Firefox and Safari (searched for updates for both). Both same.
    - In desperation, I moved to trash the contents of my plug-ins folder (when I tried to play a video next, it prompted me to update my flash player, which I did). Still no luck.
    - Rebooted my router.
    No luck at all/___sbsstatic___/migration-images/migration-img-not-avail.png Interestingly, if I play a DVD or a downloaded video, everything is fine. Even YouTube, I might pause it a couple seconds to buffer it at the beginning of a video, but it's good overall. I'd sure like to watch some hoops today/___sbsstatic___/migration-images/migration-img-not-avail.png
    Thank you in advance

    Are you on cable or DSL?
    My understanding of cable is that the more people in a neighborhood watching, the slower the connection becomes for everybody.
    There are probably 20x more people trying to watch streaming video of the basketball tournament today than anything else. It could be lack of capacity at the network host website or your internet provider.
    My video was always choppy with my old ISP on my MacBook 2,1 (and my Wii, for that matter) until I switched to a DSL provider and 3.0Mbps-rated service. Now the video streams smoothly 99% of the time. I haven't tried to watch ncaa.com/mmod in the past 24 hours, though.

  • Incredibly slow streaming of video from macbook pro to apple tv

    Hi.  We purchased an apple tv 3rd generation connected to wifi.  our internet runs about 7mb/sec.  no problem streaming movies purchased on itunes through apple tv but ridiculously slow streaming mp4 through itunes to apple tv over macbook.  when i say ridiculously, not even sure if it works... just seems to think about it.   home sharing is enabled on both devices.  i know they are communicating because i can play my music library on the tv (which is also pretty slow).  am i missing something? 

    Home sharing is done over the local network so internet speed wouldn't play a factor. I would be inclined to think it is specific to the videos you are trying to share.
    Have you made sure they are compatible with the Apple TV?
