Stuttering and Out of Sync Playback in Logic Pro X

I'm having a problem with my playback.
About 1 of every 4 times I play back audio, Logic experiences stuttering; portions glitch up and the output cuts in and out. 
Then the project plays out of sync for a few seconds before the system recovers.
This is happening on very simple scratch projects with 4 tracks or less, and about once every 4 times I hit play (which is unacceptable in my mind).
It also happens during recording which is very frustrating.
All my drivers are up to date, I've used disk utility to clean my system and repair permissions, and I have a very fast and current computer. 
My projects are on my internal drive, and set at 96khz 24-bit; but again, these are very simple tracks running off of a "blazing fast" PCIE solid-state drive.
I'm beginning to think this is a hardware problem, as I experience pops and clicks when I first play any audio on any app after the system has been idle.  The cut out effect also occurs with iTunes once in a blue moon.
Thoughts?

What is Logic's I/O Buffer set at?
Not sure what you're using for an audio Interface but 96kHz is overkill. Unless you have a pristine listening room, many $$$ worth of monitor speakers and amplifier...  the best mics, instruments, yes in can make a difference with soft instruments + a lot of effects but even then. I hope you have a high end audio interface otherwise it's pointless and unnecessarily hard on your system. Also, recent versions of OSX do a lot of writing to the drive. What make is the solid state drive, there is a known issue with some recent Samsung drives. 
Logic does better running loops/recording/playback from a separate drive although it normally should be able to handle a few tracks. Are you running any applications in the background? If so close them.

  • Video runs slow on firefox and out of sync with audio with abode flash 12.

    Ever since I installed adobe flash player 12 my videos run slow and out of sync with the audio it is like it pauses for a couple seconds and starts back working and keeps doing that.

    Hi jth10,
    The troubleshooting steps provided by Adobe can be found here: [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Windows_users]
    * Are there any settings in the Flash settings manager that changed when you updated? [http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html]
    *These are the recommended settings for specific resolutions [http://helpx.adobe.com/flash-player/kb/poor-video-quality-flash-player.html]
    You can also try to disable hardware acceleration in the Adobe settings menu.

  • I just bought a IMac and i am trying to install Logic Pro 9 but it keep failing

    I just bought a IMac and i am trying to install Logic Pro 9 but it keep failing, how do I get it to work?

    In that case it sounds like your DVDs have a physical problem or your DVD drive has an issue reading the DVD,
    I would suggest you try making DMG inages of your DVDs, save them to your Mac and try installing from the disk images instead...  (Disk Utility reads the DVDs in a slightly different way that can help get around certain physical issues)

  • Apple TV Stutters and Pauses on Streaming Playback

    I have had an Apple TV for 3 weeks and it has stuttered and paused on playback of movie trailers, podcasts, and all previews almost continuously. I have had our home broadband improved, but seen no ATV improvement. ATV starts playing SD trailers quickly, but takes an age to play anything HD.
    I have found the ATV's performance from day one to be very frustrating, and would like it to do what it says on the box, which is work seamlessly. I spoke to Apple support, and did everything that asked, including factory reset, but nothing has changed.
    I just wanted to ask whether my experience of stuttering, pausing and long loading times is the common ATV experience? If it is then this box needs no more perseverance and I will wait for an iteration that works as advertised. If not, then this box will be exchanged on Saturday and I will try again.
    I have a 5 Meg ADSL broadband line connected to Airport Extreme. I have plugged ATV into Ethernet and there is no change.

    Thanks for your replies. I have an 8 Meg line that hits about 5 Meg. I have worked with the ISP (TalkTalk), and they have upgraded my line. I have tried to use ATV both day and night, and the service remains the same.
    Am I right in understanding that none of you get the stuttering and pausing that I am talking about? I like ATV, but will be frustrated with it if its current performance continues.
    i believe TalkTalk to be one of the more heavy throttlers (although they will never admit it to you in any way).
    i don't experience any stuttering or pausing.
    to rule out your WIFI, you could connect the appletv to your router via ethernet. if the problem goes away then you know it's your WIFI network causing the issue. if the problem stays then the finger is pointed at your ISP.
    edit - i see you have already tried ethernet.
    i assume that content that has been synced to your appletv (movies, tv shows, music etc) does not suffer from the pausing or stuttering ?

  • Flash Player doesn't play smoothly and out of sync in full screen

    Hello! Everyone
    The flash player (11.2.202.235) does not play smoothly and in full screen audio and vidoe is out of sync.  I didn't use to have any problem at all, it only started about two weeks ago and since then despite trying various things (i.e. disabling hardware excelration, uninstalling & reinstalling, trying various browsers etc.) has not resolved the issue.  I don't know why it has suddenly stopped playing smoothly as I have not installed any software recently which might have cuased this. 
    I am using Windows XP (service pack3) and have dual partion with dual operating system (both XP).  There is the same problem on both operarting system and flash player won't run smoothly on either of them.  Although my computer and graphics card is quite old but the downloaded movies/DVD playback is fine even in full screen.  It runs smoothly and audio&video is in sync so I don't think it could my the graphics card. 
    As I mentioned I have tried all the browsers but without any luck.  The BBC iplayer plays ok most of the time if not in full screen but as soon as you make it full screen the vidoe is more like a slide show and very jittery and audio&video gets out of sync.  Same with youtube vidoes, they play ok when not in full screen but the video in full screen does not play smoothly and audio&vidoes gets out of sync.  However the ITV player & Channel 4 content on 4OD does not even play smoothly when not in full screen and the video&audio is out of sync all the time. 
    It would be really helpful if anyone can suggest anything to resolve this issue as I have not been able to find anything on the internet to solve the problem and its driving me up the wall.  Although I have tried to include as much details as I could think of so please let me know if I have missed any details that could be crucial in order to identify the problem.
    Thank you very much for reading this and taking the time to reply and your feedback.

    Would you mind opening a new bug on this at bugbase.adobe.com?  Please include your dxdiag report, a specific URL and a link to this forum thread.
    In the meantime, you might want to try our 11.3 beta or rollback to a previous version of the player to see if that resolves the problem.

  • Audio goes in and out of sync when burned dvd played on standard DVD player

    I made a short film recently (7:00 mins) and once completed and burned to DVD using iDVD and DVD Studio Pro about 20% of the clips have out of sync audio. Just slightly out of sync. Some more noticeable than others.
    Playing off the timeline syncs perfect, the exported prores 422 mov file syncs perfectly, and if the finished DVD is played on my mac or my pc the sync is perfect, but when played on a standard dvd player to my TV I get the syncing problem, but only at certain points through the film. As I said, about 20% of it. The rest of the film is fine.
    Shot on Canon 5d mkII - footage converted to prores 422 1920x1080. Audio recorded on Zoom H4N with some ADR recorded on logic pro. Audio synced manually using clapper board reference. Using a 27'iMac with current OSX update as of 14 March 2011. Edited in FCP 7, exported to proress 422, burned to DVD with current iDVD and DVD Studio Pro, all current versions and updates.
    I have tried exporting to mpg4 and mpg2 - no joy. I checked audio bit rates and discovered the logic recorded stuff was 44.1khz as opposed to 48, so I converted to 48 but still no fix.
    I am STUMPPED
    Any suggestions?
    Cheers
    Dallas

    Should I convert just the clips which are out of sync in the DVD, or all of theclips in the FCP timeline?
    If that is the issue, wouldn't I have the problem in the final prores mov as opposed to just when its played dvd to tv?
    Ill try it though. Its an odd problem so its likely to have an odd solution. Willing to try anything at this point.
    Thank you.

  • DVCAM capture choppy and out of sync

    I'm capturing Sony DVCAM tapes using a Panasonic DVX camera & firewire 400 four-to-six pin cable into FCP using the DV NTSC 29.97 setting.
    The tape plays fine in the camera, but the captured clips in the browser are choppy and way out of sync (and are that way when brought into a sequence, too).
    There isn't a DVCAM setting that I can see for the capture, and DVCAM is just DV format anyway... or is it? Any tips? Do I need to use a Sony camera for the capture? Rrrrgh....

    If the material is actually DVCAM media it will not play back in a Panasonic camera. You need a Sony device for playback. It's just DV but it's recorded differently, different head pitch with higher speed tape.

  • Dealing with dropped frames and out of sync audio

    Hi!
    I'm using Final Cut Studio 3 and I'm trying to record some video from a pretty old MiniDV-camera. The problem is that a have some dropped frames and when I record the whole thing it gets out of sync.
    By default Final Cut aborts the capture (without saving) when it finds dropped frames. That won't work for me. I start recording, it records a couple of minutes and then it just aborts without saving anything.
    I tried to record the entire tape when using the option of not aborting on dropped frames. I recorded the entire video but not it gets more and more out of sync later and later in the video.
    So, do you have any suggestions on how to deal with this? Maybe I can use an external application for this cause I haven't found a way to deal with this in Final cut.
    Best
    Felix

    Hi(Bonjour)!
    Did you shoot in DV or HDV ?
    Did you try to capture HDV with Apple Intermediate Codec 1080i60 (or 50 for europe)?
    Does you downconvert HDV shooted to DV upon capturing from camcorder ?
    DV-NTSC 48 kHz is the way to go with downconverted material.
    Does your DV audio setting is 16 bit on FX1 ? (HDV is a fixed one).

  • XMPSES file extension and Out of Sync issues

    I captured a VHS tape to an AVI. If I watch this file using Windows Media player, the audio and video are in sync. I then imported the AVI into PE11 and created a video project. I selected the MPEG option for Computer under Publish+Share. I did not change any settings. The preset is NTSC DVD Standard. When the project was complete, I now have two files
    FILENAME.MPG
    FILENAME.MPG.XMPSES
    Also, when I play the .MPG file using Windows Media player, the audio and video are out of sync. The audio is delayed by a couple seconds.
    I am using Windows 8.1
    Does anyone know why PE11 creates the two files? Is this related to the sync issues?
    thanks,

    uberjaeger
    That .xmpses is an informational file attributed to Adobe and described as a Premiere Elements DVD Marker File (has information about DVD marker project, chapters, titles and scenes). I can confirm its existance. I do not suspect that as the source of your out of sync audio in your Publish+Share/Computer/MPEG with NTSC DVD Standard export.
    How did you capture the VHS tape to AVI and what type of AVI did put on the Premiere Elements 11 Timeline....DV AVI? If DV AVI, was it type 1 or type 2?
    What were the properties of this import into Premiere Elements 11 - 720 x 480 4:3 @ 29.97 interlaced frames per second or something else? What did you use for Add Media?
    What was the project preset of this Premiere Elements 11 project? Did you set the project preset to NTSC DV Standard manually before the Add Media or did you let the program automatically set the project preset based on the first video drag to the project's Timeline? If the program took charge, what did it set? Please see Edit Menu/Project Settings/General and the readings for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio (even if grayed out).
    If you take your Timeline directly to Publish+Share/Disc/DVD disc, does the DVD-VIDEO standard on DVD disc play back with out of sync audio?
    By the way, do you have the VLC Player and does your mpg play back with audio out of sync there?
    Let us start here and then decide what next.
    Thank you.

  • A hiccup and out of sync

    Well, I've captured my first two tapes. Had a bit of a problem with them, as they were out of sync at first, but after searching this forum, found that the problem was in the fact that the tapes were recorded in 12 bit, requiring me to capture them at 32 KHz. (if a camera is capable of 16 bit audio, isn't it better to record it at that?). I captured both tapes using the "clip" strategy, as the capture all gave me some problems. On one of the tapes, there is sort of a stutter in the video, and then the audio from that point on is out of sync. Now, I will figure something out, and I guess it will involve me separating the audio from the video, and adjusting the audio from that point onwards, but if anyone knows of any magic wand I can wave, or can see any pitfalls in my path, by all means chime in. Thanks in advance.

    I've got a easy workaround. I was using two cameras, and I've placed them, synced, on two video tracks (and their accompanying audio tracks). If I just disable the audio on the camera with the stutter, this seems to solve everything. I didn't think it would-I thought the stutter would prevent me from syncing straight through even on the other camera audio track. But it seems to have worked.

  • AJA audio on HD capture crackles and out of sync

    AJA Kona LHe card
    DV capture is fine.
    Tried to capture HD and audio has crackle and worse- way out of sync.
    I checked settings again and again- I uninstalled and reinstalled the drivers. I tried the latest drivers and the previous versions.
    I can't get this card to capture HD sync audio.
    It's a 1080i signal component- audio is coming off a mixer.
    This set-up works for DV capture and never fell out of sync with a Decklink- so I know it's correct.
    any suggestions? Before I call AJA.

    NOpe. Call AJA.
    I have the Kona LH and Kona 3 and have not experienced this issue.

  • "Pixelated" and out of sync movies played in flash

    Hello.
    Recently i had a problem with my flash player after installing a Windows Update (not sure if its related).
    Movies played on sites like YouTube became out of sync and pixelated.
    Im not exactly sure how to explain this, so i uploaded a few pictures of the issue.

    The sound is normal and the only thing affected if the video. If is there is any sudden movement in the video, it will distort the image.
    Im using v10.2 and am on Win7 x64. Viewing the video's in Firefox.
    I had the same issue on my older computer a while back using Vista x64 in both Firefox and IE.
    The problem on my older computer was resolved by simply restarting the computer. But this time that didnt work.
    I also tried uninstalling and reinstalling flash, and restarted multiple times.
    If anyone could help me solve this puzzle please let me know. Or if you need any more info on my specs or setup, just ask =)
    I use the flash player in a daily basis. So this just really ruined my day =/

  • Green pixels and out of sync movie on PAL

    I put subtitles on an NTSC timeline and movie. I exported as NTSC. I went to Compressor and converted to PAL. The footage is out of sync and there are frames with green pixles and fill the whole screen.
    I notice these green frames on the timeline and they were disappearing when ever I rendered the clip. They appear back on the PAL conversion, but not on the TSC export.
    Thanks for any info.

    Did you ever get an answer on this?  I have the exact same problem.  Windows Vista, iTunes 10.5.3.3
    Songs play great, videos are choppy and warble but they play fine on QuickTime.

  • Logic Pro x - additional content downloads and installs but it won't show up in my Logic Pro X. Where is the add'l content downloaded and how do I activate on Logic Pro X?

    The additional content downloads and installs, but it won't show up in my Logic Pro X. I cannot find the "Library" folder where this additional content is  downloaded to and can't seem to activate the new loops and instruments in my Logic Pro X (i.e. loops are still greyed out). Any solutions?

    similar problem that I'm hoping revives this thread. Took over 24hrs to dload additional content (after another full day for the actual problem) due to a bad dload rate. so quitted, and relocated closer to my wifi router. Restart, open logic x, Menu bar:  Logic Pro/ Download Additional content ...Tells me i have no internet connection.... Ahh... I do, I'm using it right now! Tried restarting and relaunching. same thing every time.
    Any clues?
    This whole apple upgrade has been so disappointing! All i wanted to do was reinstall logic 9! $2500 later and I'm still struggling. ***!
