Movie "stutters" into slices....audio playback is fine

Out of the blue, all my QT movies are cut into vertical slices. Audio plays fine, but picture is in a dozen pieces. Help!

Open the QuickTime Control Panel / Advanced tab and switch the video to "Safe mode".
Quit and relaunch QuickTime and try the file again.

  • IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

    iMovie 11  audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
    I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
    The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
    I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

    I have a fix - or rather, a workaround.
    WARNING: It is lengthy, but still far better than starting a new project from scratch.
    I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
    ...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
    It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
    This will require:
    A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
    1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
    2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
    3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too,  as they will be extremely helpful later.
    4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
    This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
    5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
    You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
    Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
    We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
    VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
    I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
    6.) Once you are done with this, export your newly pieced together audio track.
    7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
    8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
    9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
    Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
    YOU'RE FINALLY DONE!!!
    I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
    DON'T USE IMOVIE EVER AGAIN.
    I hope this helped!

  • New MAC PRO: itunes audio playback-stuttering, glitching, skipping

    I have a brand new mac pro 3.2ghz quad, with 8gb ram (bought a couple weeks ago). All seems fine with the exception of brief skips, glitches and stutters with audio playback in itunes. I tried updating to itunes 11 and this did not resolve the problem. My music files play fine on my girlfriends macbook pro (purchased over a year ago), and never had any problems on my old machine (imac 24inch aluminum). I went to apple with the problem and after multiple system recoveries they determined that the computer was faulty and sent me a replacement. I just received the replacement and tested out some downloaded music from the itunes store and the same problem happened. Am I just unlucky to get two computers with this issue? Is it the Mac Pros? Has anyone had this issue with mac based machines, specifically the mac pros? I saw another thread on the issue but seemed to be primarily windows users running itunes. The skipping happens as frequent as every 20-30 seconds to every few minutes, but it is definitely enough to notice
    Thanks.
    Baffled,
    Greg

    Hi Greg.
    I seem to have discovered this problem this weekend. I listen to a lot of music from my apple devices and have done for years. What I have noticed this weekend is that both my Macbook 2008 and iMac late 2010 both suffer with a brief stutter every minute or so making the enjoyment of listening to music a little annoying. Both are running Mountain Lion 10.8.2. My iMac is running the 2.93 GHz intel i7 processor with 8GB ram. Playing music should be a doddle!
    From my point of view both Macs are running independently to external speakers. The music I am running on those 2 devices has been ripped on both devices. e.g. Macbook has ripped and plays Apple Lossless format and my iMac has ripped and plays songs in 320kbps. My guess is its a bug with the new iTunes 11 or Mountain Lion although I have been using 11 since its release.
    While I'm not able to supply a fix I think its safe to say its not your new Mac Pro. One other thing to note is that I have been running up until this weekend a 7 or 8 year old Mac Mini as a media device in my kitchen playing Apple Lossless format with no issues at all. This device however is running Snow Leopard with all updates applied. The Macbook is now playing the Lossless music with stutters that was ripped on the Mac Mini that was playing OK.
    So is the problem Mountain Lion?
    Take care

  • Windows 7 (64bit)  itunes choppy stuttering audio playback

    Hi All,
    I'm new to these forums so apologise in advance if this topic has been covered already....
    I recently upgraded my Dell to Windows 7 64 bit and also upgraded iTunes/ QuickTime to the 64 bit version which resulted in audio playback in iTunes stuttering every few seconds. I waited for the latest release thinking it must be a bug which apple are addressing. Just installed it (ver. 10.1.056) but the problems is still there. I’ve tweaked quick time, installed the newest possible audio drivers, for my soundcard nothing makes any difference. If i use windows media player to play my music its absolutely fine , no stuttering , no problems at all. So why can't apple get their act together?
    Has anyone else experienced this problem or found a fix? if so please get in touch.
    Thanks for reading
    Dave

    I have a similar problem. I recently got a new laptop with Windows 7 64-Bit. I've started to rebuild my iTunes library and it was all going well. However, I noticed a lot of my files are starting to loop the first second or so of the intro for around 6 seconds before the song plays normally. At the time, I didn't think of this as a problem, but the exact same looping occurs on the iPod itself on the same files, at the same time, everytime.
    After deleting the broken files and getting new versions of the same songs, I decided to test them in Windows Media Player first and there was no intro looping. Assuming all was well, I added these files to iTunes, tidied up the song info, added album art and then played the tracks to see if the looping was still gone. Some of the tracks were fine, but others had developed the intro looping. Playing these same files in Windows Media Player again, after running them throgh iTunes, also now has the looping which it previously did not.
    iTunes seems to be destroying my files. Is there any way to fix this?

  • Audio playback stuttering using AirPlay under iOS 8

    I encountered a lot stuttering in audio playback with apples music app and Spotify using AirPlay mode with my AirPort express. It occurs not only in background use, but also when the apps are on top. Reseted all devices, nothing helped the issue. Very annoying, it never happend in the previous builds. I think it's a iOS 8 problem and hope Apple solves it soon. My internet works fine at 50 mbit though.

    I've contacted Apple Care lately, and though they where very nice and kind, they pretended to never have heard about the issue and claimed, it should work. they gave it to their developing engineers though. Let's wait and see...

  • Recording with audio playback slowed down 65% what speed do I need to speed the video back up to to get it into real time?

    Ive recorded a test video with audio/music playback slowed down 65% what speed do I need to speed the video back up to to get it into "real" time?
    If I'd slowed the audio playback down 50% I would make the video 100% faster.
    If I'd slowed the audio playback down 100% I would make the video 200% faster.
    So its obviously somewhere inbetween speeding up by 100-200%
    Sorry but its melting my brain today and I cant remember the calculation.
    thanks

    hey all
    Thanks for the advise on this. I will explain a little more what am have/am intending to do.
    I have used Audacity to slow the song down (Effect>Change Tempo)
    Audacity will allow me slow the original song down by up to 99% (Or anything in-between up to 3 decimal places)
    Unfortunately I am working to a time restraint of 12 minutes per clip (as my DSLR will only allow up to a 12 minute clip).
    The song at normal speed is 4 minutes long.
    Originally I slowed the audio down by 50% (Making the audio 8 minutes long), lip synced to it using a rasta blaster and recorded the video using my DSLR at 720p 50fps.
    I then imported the video and audio I had been lip syncing to into FCPX.
    I sped up the video by x2 (equivalent to speeding it up 200%)
    Retime>Fast 2X
    Layered the PROPER normal speed audio back over the top and all was fine.
    Test video complete.
    (You can ignore the 65% slowed down audio I mentioned earlier if you like, that was just an example of a slower than 50% audio test)
    Firstly what I really want to do is to be able to slow the AUDIO down as much as possible (But still within the restraints of only being able to adjust FCPX retiming within a whole 1 percentage in the final video edit), but have the AUDIO of the song as near to/under 12 minutes as possible.
    I will then re-record the video again to this new slowed down audio.
    Secondly I will speed up the video from 12 minutes to 4 minutes.
    Thirdly I will layer the correct 100% Normal AUDIO on top.
    The FINISHED video should then look like everyone is wizzing around at high speed but the guitar playing/lyrics look like they are being played/sung at the normal speed.
    Whatever happens (due to the constraints of FCPX) I need the calculations to work so that FCPX is retimed exactly to a whole 1% for the final video to sync up correctly.
    So what I need to know in a nut shell is:-
    What calculation do I use to work out the percentage to slow a 4 minute song down to a 12 minute song?
    What calculation do I use to work out the percentage of how much I need to then speed the 12 minute video up to turn it back into a 4 minute video?
    My mind is melting

  • When I import audio and move it into my timeline the project will no longer play?

    When I import audio and move it into my timeline the project will no longer play?

    The audio is a .wav file created in Audacity.
    The OS is Windows XP
    The verison is CS4
    I have included images of the Sequence settings and the playback settings because I was not sure what information you would need.
    I am not sure what you mean by waiting for the Audio to conform but I know I have imported the audio and gone back the next day and tried to place it in the timeline and it still did not work.

  • When I compress my movie to quicktime, the audio doesn't sync properly, even though it looks fine in iMovie. How do I fix this?

    When I compress my movie to quicktime, the audio doesn't sync properly, even though it looks fine in iMovie. How do I fix this?

    Audio on the timeline, especially stream, tends to play very reliably. Is this project under any NDA or can you provide a FLA to examine? Let me know if you want to private message it and I'll shoot you a message.
    What version of Flash Player are you targeting and is this AS2 or AS3?

  • Can one move or upload a garageband project done on an iPad into logic for further and finer tweaking?

    Can one move or upload a garageband project done on an iPad into logic for further and finer tweaking?

    Share your GarageBand iPad project to iTunes as a project. Then you can import it into GarageBand and upgrade it to a GarageBand Mac project. And Logic can open GarageBand for Mac projects.

  • No Audio Playback due to Error Message "Disk is too slow. (Prepare) (-10001)"

    Out of the blue, no audio playback.  Was working just fine earlier today.
    I repeatedly get the error message:
    Disk is too slow. (Prepare)
    (-10001)
    NOTE: I have more than enough disc space.  That is NOT the issue.
    I also just got a second error message:
    Part of the Project was not played
    This project has too many real instrument tracks to be played in real-time. To optimize performance, see the 'Optimizing GarageBand performance' page in GarageBand Help.
    NOTE: Odd as I have only 2 tracks in the GarageBand file.
    Any others experience this?  Suggestions?

    Have a look into the Preferences folder (YourUserFolder/Libraries/Preferences/) and trash all Logic preferences.
    You'll have to setup the program again.

  • Trouble exporting any mov files into H264 after adding K-Lite codec pack into Windows XP SP3.

    I have QuickTime 7.7 (1680.34) installed. I have used it extensively and exported the video separate from the audio and extracted and used filters and it has all worked great with all of the other codecs I have had installed. It even worked great after I recently installed this K-Lite codec pack that actually saved files in a *.hdmov file type and I was able to view them with the Media Player Classic .... (I have Windows XP update 3)  and see what I could do over there and then go back to saving them as *.mov file types and work in QuickTime Pro. And still export them relatively fast to their latest H264 format.
    I gave more file types to the Media Player Classic. I think along the line of the just the *.3g2 and *.mp4 and took them away from QuickTime but still keeping the *.mov, *.qt and *.mqv  file types .... and that is when I think everything must have changed.  all of a sudden I can not save any *.hdmov files and the export process in QuickTime takes longer than forever.
    I thought that I had reconfigured Media Player Classic back to its default ....
    and it should all go back to being how it was.
    Is there some Direct Show filter or codec that upsets QuickTime Pro ... that I might have not reset back to what it was?
    Any codec help would be much appreciated.
    This is what the K-Lite site says in one instance about H264:
    If the video that you are playing contains H.264 video, then you could try using another decoder. The codec pack by default uses ffdshow for decoding H.264 video. This is a free and open-source decoder. Other decoders exist that have better performance as ffdshow. They should give you smoother playback, specially if you have a dual-core or quad-core processor.
    Alternative H.264 decoders are:
    CoreAVC. This decoder is unfortunately not available for free.
    DivX H.264 decoder. This decoder is available for free as part of the DivX Bundle. Tip: disable everything in the bundle except the H.264 decoder.
    ffmpeg-mt. This is an experimental multi-threaded version of the libavcodec decoding library, which is used by ffdshow. You can select ffmpeg-mt as decoder in ffdshow video decoder configuration.
    MPC DXVA H.264 decoder. This is an internal decoder of Media Player Classic Homecinema. It uses your graphics card to perform most of the decoding process, resulting is a very low CPU usage. You can enable this decoder though: MPC Options -> Internal Filters. Note: this decoder has some specific requirements.
    I downloaded the DivX bundle and will pull out that codec. I bought the CoreAVC for $13 but Norton said it was a risky file when I downloaded it ... (I have a question into the site about that) and I will try the ffmpeg-mt codec as well as see what they say about the last one. I will also try to undo everything I did that happened I guess before QuickTime started to export so slow that it is not even worth it to try and convert a mov file into H264.
    Sorry so long ... I just was trying to lay out the things I have attempted, will attempt to try and improve the situation.
    Thanks again very much if anyone makes it thru this ... geez .. sorry.

    Hello Tim,
    I decided to do a clean install, a fresh new installation of windows and all its updates, I didn't get the option of
    install SP1 yet.
    After that I only installed Catalyst drivers: 11.5 and Realtek HD audio drivers, all downloaded on May 24 2011.
    Then latest FFDShow and MPC-HC to test, both x64 versions Nothing else installed.
    Only a fresh copy of windows with its updates and those mentioned drivers.
    To my surprise, it happened a gain.
    It still crashes after a while when playing MKV videos.
    It's weird, because it doesn't happen with avi's or mp4's.
    So, there must be something wrong with one of windows updates that creates this windows FREEZE.
    Also there is no possibility to find out what error it is in "Event Viewer" as nothing gets recorded there. Anyone could
    advise?
    Thanks

  • Best settings for exporting and dropping a MOV file into iDVD7?

    I have a movie (originally shot in HD), made in iMovieHD6, and that I'd like to export and drop into iDVD7. *What settings would the brain trust recommend?* I cannot seem to get iDVD to render a good version through direct export from iMovie. (As a side, I wonder if it is because I started this process by bringing AVCHD files from my camera into iMovie8 and "going backwards" to iMovieHD6.)

    I have used Pro-res from Final Cut Pro into iDVD and it works.
    *This is from iDVD help menu:*
    Video and image formats that work with iDVD
    You can use these movie and graphic formats in iDVD:
    ◼
    Most video or image files supported by QuickTime (see the list of unsupported QuickTime formats below)
    ◼
    16:9 widescreen formats
    ◼
    AAC, MP3, and AIFF audio files
    ◼
    Any format from iMovie: DV, high-definition video (HDV), MPEG-2 SD, MPEG-2 SD, MPEG-4 SD, MPEG-4 HD, and AVCHD
    High definition video is converted to work with the format of your project. iDVD supports using 16:9 widescreen video; therefore, when your DVD plays on a DVD player that supports widescreen format, the footage appears in its original aspect ratio.
    The following video and image formats are not supported in iDVD:
    ◼
    Copyrighted or protected videos.
    ◼
    Movies saved in thousands of colors using the “none” compression setting in iMovie.
    ◼
    48-bit color images (16 bits per color). To use source files in one of these formats in iDVD, save them in a supported format.
    ◼
    Aurora uncompressed files. For best results, export Aurora clips as DV-format video before importing them into iDVD.
    ◼
    QuickTime VR, MPEG-1 or MPEG-2, Flash, streaming or encrypted movies, or QuickTime spanned movies. You can’t add MPEG-1 or MPEG-2 files to an iDVD project because they don’t contain standard video tracks.

  • FCP Splits QT movie file into several files... problem and solution.

    Hi All,
    I was having problems exporting a QT movie (Video Only) of a 20 min Reel within a Feature Film I edited. The Database was quite large - the film was 2Hrs and Footage was about 12X.
    FCP would split the QT movie file into several files - only one of which was openable (either in FCP or the QT player). To my surprise, I also found that even though the file opened fine, I would get an error message when trying to copy it or its associated files over to another HD (Tiger would abort, after giving me an error No. and saying that there was an error while copying). The problem was repeatable and specific to this sequence.
    After some testing, I found that copying the clips (Video Only) to another sequence and re-exporting, seemed to solve the problem. My take on this is that too many ( > 12? ) Audio tracks causes problems in FCP when the database is large.
    But I do need these additional tracks. Any work arounds?
    Thanks,
    RD

    First, look in System Settings, and see if you've checked the box to limit file size to 2GB. Uncheck that box. See if that helps.
    Or it could just be a corrupt project causing the problem.

  • Copying movie files into a presentation

    Hi.
    I have a keynote presentation which includes lots of pictures. When I saved my presentation, I saved it with the option to copy the image files into my presentation document.
    However, I would like to copy some movie files into the presentation as well, but I do not want the movie files to be copied into the keynote presentation document.
    Is there anyway I can do this? If you have any suggestions, please let me know. Thank you very much.

    Keynote ALWAYS copie images into the file (except the theme images from the built-in themes, but it always copies YOUR images into the file). When you first saved it, did you check the box that said copy movies and audio into the file? If you did NOT check this then you're fine. If you did, you might have to make a new file and copy over your slides, then save it and make sure that box is UNCHECKED when you save it the first time.
