System-Wide Audio/Video Syncing

I'm aware of VLC's capability to sync the audio to the video in milliseconds. It's really useful.
However, I've run into an issue where there is a lengthy video online (Flash) that is out of sync. Are there any solutions to syncing the two system-wide (as I doubt there are any browser extensions to do this)?
Now, the tough part is, the video is ahead of the audio. Would this require caching the video for a few milliseconds to allow the audio to catch up?

Please can anyone, who has places a whole movie on their ipod let us know how u did it and how it worked, bcuz i tried converting another moview, and it was a little bttr than the first movie, but there is still a noticeable delay none the less. plz help..

  • 'Source play' and 'audio-video sync' problems with PE8 on fast WIN7 64 bit computer

    I am transferring Hi8 videos, about 2 hours long, to my WIN7 64 bit computer with PE8.  [Dell Mobile Precision M4400 Computer Workstation (Intel Core 2 Duo T9900 500GB/4GB); NVIDIA Quadro FX 770M, 512MB] I seem to have several problems: 
    First, after importing the file (.avi), I get a message about ‘dropped frames.’ 
    Secondly, when I try to play the video in the source monitor, the audio plays but the video doesn’t; it only shows the first frame [this is after waiting until the video is ?recognized? ]   I can use the shift-arrow key and see that the video is there.
    Thirdly, I can play the .avi file in other players, e.g., avidemux or PE pro CS5 on another computer.  There, I see that the audio and video are not in sync; the audio can be up to 300 ms ahead of the video (as determined using avidemux). 
    Questions:
    1.  Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
    2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

    "I think you're telling me you're using a backwards compatible Digital8  camcorder to capture your video as DV-AVIs. Is that right?" YES
    "Are you using  Premiere Elements to do this capturing?" YES, AS ABOVE PE8
    "Go to the File menu and select Properties. It should show a standard DV codec being used for your video and audio."
    WMP v12 is dumb. Under properties, media, it says 'video.'  However, avidemux gave me the information state above: video -- Codec 4CC: dvsd, frame rate: 29.971 fps; audio -- codec: PCM, channels: Stereo, frequency: 48 kHz.
    So, back to the Questions:
    1.  Why doesn’t the source  monitor play the video? Is this a problem with PE8 (latest update as of 3  March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
    2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

  • Audio/Video sync drift in Premiere CS5.5, but not in CS6

    I have a QuickTime file with the following specs:
    Video: H.264, 854x480, 29.99fps
    Audio: AAC, 44100 Hz
    When I open the file in QT player, or in Adobe Premiere CS6, there is no issue with Audio/Video sync.
    However, when I import the file in Premiere CS 5.5, there is a drift in the Audio/Video sync.
    Is there something I can do in Premiere CS 5.5 to avoid or fix the drift?
    Thanks.

    I had a similar problem and these are the steps I took to fix it.
    First I deleted the files in "Adobe Premiere Pro Preview Files" for the project in question. I reopened Premiere and it appeared that deleting those files didn't seem to do anything as everything in the project looked the same.
    I then disconnected the drive with the footage on it and opened Premiere. When it asked where the footage was, I told it to Offline All. I then went into Preferences > Media and hit Clean for the Media Cache Database. This had to be done because it only cleans the cache for files that are no longer connected with the project (as noted above). I closed and reopened the project, selected everything in the Project window, right clicked and chose Relink Media. I located one file and it relinked the rest automatically.
    Now, finally, Premiere is re-conforming all the audio. Hooray!

  • Regular problem with video playback & audio video sync

    So, I am regularly having two problems (I wonder whether they are connected) that I cannot solve and am hoping someone can tell me if I am out of luck or if I need to do something or add something.
    For example, because it happened again today. These are details about the file stuff:
    Type:AVI
    Bit Rate:133kbps
    Dimensions:624x352
    Audio format: LameMP3
    Frame rate: 23 frames/second
    Data Rate: 1131 kbps
    Video Sample Size: 12 bit
    Video Compression: XVID
    First Problem: If I play the file - I use Media Player Classic - it plays fine. Open it in Windows Media Player and it plays fine. Try to edit it in Premiere and the file loaded into Premiere is filled with what I believe are called audio video sync problems, so I have to constantly unlink audio and video and adjust it. It loads and does not need to conform.
    I have the same problem on my laptop(Windows XP Home) and desktop (XP Pro), the desktop with twice the RAM. I have the K-lite Mega codec pack installed. I would call myself a beginner when it comes to video editing. I understand generally what codecs are but I am not capable to making any tweaks to the K-lite Mega codec pack (if I should have) so it is setup as installed.
    Second Problem: The video in the playback box never plays back normally. I have tried adjusting the playback settings: have changed the aspect ratio between the software and harware option and adjusted between the three desktop display options. Occasionally it is "ok" but most of the time not and never just normal.
    Any help is much appreciated.
    Thank you.

    I tried this already and then we had a blackout so going to try again and hope it goes through before a second one...lol
    Hello:
    Thank you Robert J. Johnston, the_wine_snob, Paul_LS and SteveGrisetti for your help so far.
    So this is where I am at now:
    Files all seem to be of the same type, so I will just say "the file" for the one I am working with right now.
    Loaded file into VirtualDub.  I like that program.  Well done, whoever made it.  Did some basic cutting of unwanted stuff.  Saved as AVI.  Saved both a Direct Stream Copy and a Full Processing Copy.
    Opened the FP copy in Premiere Elements and it plays without audio sync problems that I can see. Have edited it some so far and still no problems.
    Before I do any more editing work, I decided to save it (SHARE) in different formats to see what happens.
    Goal: Looking for no audio sync problems.  Best quality I can get with a 1GB file size limit.
    Saved as DV-AVI:  plays fine.  no audio sync probelms.  love the video quality.  2.95GB, so too big
    Saved as Flash:  Do not see any audio sync problems.  Do NOT like the quality (flips back and forth between clear and all pixely (is that a word).  32 MG
    Saved as Mpeg: Media Player won't play it (thought Media Player with KL Mega Codec played everything?) (It loads it but doesn't play?); Quicktime won't play it.  Windows Media Player just did.  Do not see any audio sync problems.  Like the video quality. 631 MB.
    Saved as Windows Media: Do not "think" there are any audio sync problems; if there are, they are very subtle.  Not crazy about video quality.  Better than flash video option though still flickers between two types of qaulity (if that makes sense) . 52MB
    Any suggestions as to what I should do at this point to meet my stated goal.  I assume [share]ing is what I should do?  Is there any exporting or any other options I do not know about.  Without your help I figure I will Share to MPEG?  Not sure why Media Player won't play it and Windows Media Player will?
    Any thoughts on the best choice for me?  Thanks for your help.

  • Is there a system wide audio manager?

    I'm trying to find a system wide audio manager for my MacBook Pro that won't cause voice lag or delays. Any suggestions?

    they say :
    To remove Audio Hijack Pro, simply place it in the Trash. If you've installed any of the extra components, you may wish to uninstall them first using the Install Extras menu item in the Audio Hijack Pro menu.
    extras seemingly being InstantOn.kext & Rogue Amoeba Schedule Helper.app although perhaps others.
    Find any File makes finding leftovers a little easier.

  • Audio/Video sync program for Power PC G5

    Greetings to ALL,  I am attempting to determine if there is a audio/video sync program for my PPC G5 running 10.5.8?
    Suggestions would be great because if I cannot locate a program I am at the end of the road for this little project.
    Working with a Nikon D7000 and RODE Pro Mic and looking to get the Tascam DR 100MkII recorder if I can figure out how to get things to jell.
    Thank You, pc

    Even if syncing directly is not practical, iTunes can manage audio files, has many organization features for audio, such as playlists and folders of playlist, and tags that can be applied to multiple audio and video files are supported by it.   MPEG4Streamclip offfers a variety of conversion tools that are available for PowerPC for video and will bring videos to work with iTunes.  H.264 MPEG4s are the best for iTunes.
    And http://www.lemkesoft.com/ GraphicConverter lets you browse Finder folders, which you can tag by month, and year, and even time, in a hierarchy that makes sure you don't do any duplication.   Since the Nikon D7000 does write to standard SD cards, you just need a Mac OS X 10.5 supporting SD card reader.  Many SansDisk readers supports it.

    BUG: Speed Change + Audio Transition = No Audio-Video Sync
    If you change the speed of clips (125%) and make an audio transition between them (power), the audio runs out of sync. The longer the transition, the more out of sync.

  • IDVD 08 audio/video sync drift toward end of DVD movie - fix/workaround?

    Anyone know how I can fix this issue? It's driving me crazy.
    I've just spent a few evenings in iMovie 08, editing together the video of my son's birth. All looked & amazingly good in iMovie. The "Large" .m4v file output by iMovie - Shared with the Media Browser - plays perfectly in Quicktime too.
    However, after adding that shared movie to iDVD 08, and burning a DVD, I noticed that the audio sync drifts toward the end of the Movie when plated back. At the start of the DVD all seems well, but by the end of the ~1hr 20 minute movie the audio is unbearably out of sync with the video. Completely unwatchable.
    After a little Googling I came across some reports that iDVD might not deal well with video that's been recorded with 12-bit audio. I've confirmed that my camcorder is (was!) set to 12-bit rather than 16-bit (the default, I'm sure). So if that's the problem I'm hosed... it's not like I can get a retake on that footage
    Is there a reasonable workaround for this issue? I'm obviously unable to re-take the video (or the other 10 hours of DV video tape I've yet to use in an iMovie project). Ideally I'd like Apple to release a patch for this. Shouldn't it be possible for iDVD to account for audio that was originally recorded in 12-bit... even if it's just a checkbox you have to select to tip it off?
    Then again, perhaps this is totally unrelated to the 12-bit issue, and this is just a run of the mill bug?
    As I said... iMovie generates a MPEG4 video file of the Movie that looks/sounds perfect, so it seems this sync issue's being created somewhere in iDVD as it's rendering the audio/video to burn to the DVD...
    Thanks in advance.

    I've tried most of the options I can think of, and the audio sync drift issue continues on this ~1hr 12 minute iMovie/iDVD 08 project.
    A couple of promising ideas tried used QT Pro, to export the audio track from the iMovie generated MPEG-4 file - as a WAV file, resampling to 48kHz and 16-bit... then Adding this back to the video track in the MPEG-4 file (having deleted the original audio track). In another test I also tried the Add to Selection and Scale option. Oddly enough I think the Add to Selection and Scale attempt generated more sync issues than before in the final DVD movie... so I stuck with the MPEG-4 file containing the video track and the added, resampled at 48kHz & 16 bit, WAV audio track.
    This was saved as a self contained Movie file, producing a QT .mov file. I moved this .mov file into the iDVD projects directory structure so that it was avalable in iDVD's Media Browser. I then reworked the iDVD project to use this QT large.mov file, instead of the original iMovie large.m4v file.
    As a reminder... the original large.m4v file has the following properties:
    29.97 FPS H.264 Decoder, 960 x 540, Millions
    AAC, Stereo (L R), 44.100 kHz
    0:01:12:07.16 duration
    The resampled and saved QT MOV file has the following properties:
    29.97 FPS H.264 Decoder, 960 x 540, Millions
    16-bit Integer (Little Endian), Stereo, 48.000 kHz
    0:01:12:07.16 duration
    BOTH versions of this Movie file play flawlessly within QT Pro... there's no audio sync drift evident toward the end of the movie unless I use iDVD 08 to burn either movie file to a Physical DVD (or DVD Disk Image). In both cases the resultant DVD Movie exhibits significant audio sync drift as the ~1hr 12 minute movie progresses. The sync goes out by ~ <= 1 second based on a rough visual assessment.
    I've not yet tried to burn either the original iMovie produced MPEG-4 video file or my QT Pro tweaked audio track .MOV file version to a DVD on my PC...
    ... But I have used an application called Burn (referenced in this earlier/archived iDVD sync drift forum post: http://discussions.apple.com/thread.jspa?threadID=1332100 by user F Shippey - http://burn-osx.sourceforge.net/) to take the QT Pro tweaked .mov file version of the original MPEG-4 file and burn it to a DVD...
    Results:
    The Burn app burnt DVD plays with NO audio sync issues!... Even though it was generated from the same audio tweaked (48kHz/16-bit resampled) QT Pro .mov file.
    However, whenever I burn a DVD using iDVD 08 the audio sync gradually drifts. It matters not whether I use the original iMovie 08 generated MPEG-4 movie file, or the QT Pro version of that file with the resampled audio track (the same one that works fine with Burn).
    It sure looks to me like iDVD has a problem... Again, refer to http://discussions.apple.com/thread.jspa?threadID=1332100 for someone else who seems to have run into similar challenges.
    Am I overlooking something?
    Thanks in advance.

  • Audio / video sync issue in playback

    for every recording i've made, when i play back the archive there is noticable lack of sync between the audio and the person's mouth.   the video seems to lag behind by almost a second.  the good news at least is that the delta is constant.
    has anyone else experienced this?  it's happening in any scendario i try, even if i'm just recording myself. 
    is the LCCS dev team aware of this?  since audio and video streams are recorded separately, is there any way for me to programatically 'nudge' the streams into sync?
    it's currently a show stopper, it looks really bad when the sync is so obviously absent.

    finally getting back to this..
    i did as you suggested and recorded a video of myself using the recording and playback examples provided with the SDK (the 2.2 newest version btw).
    the de-syncing of audio and video is definitely there.  it seems especially bad for longer recordings.  however, an interesting thing i discovered in playback:
    - sometimes, if i drag the playhead somewhere in the recording, pause, and then hit play, video and audio fall into sync. 
    - if i start playback from the beginning of the recording, audio/video is always out of sync.
    i understand that the video and audio streams are recorded separately and thus played back separately.  my guess is that when those streams are retrieved and playback begins, one starts before/after the other because they're not retrieved at exactly the same time.  it seems some extra work is required to ensure that their playback commences at exactly the same timestamp within each stream.
    i can provide my recordings as an example if required.
    this is a total showstopper for me.  it renders the entire recording service useless if the playback can't have sync between audio and video.  i would be happy to help with testing this more.  can someone from the LCCS team comment on this issue?
    thanks

  • Preference Pane for system wide audio EQ? (2 yrs later)

    I fully agree with the quoted message underneath.
    *"Is there some sort of universal Equalizer I can apply to all my audio? A Preference Pane would be great! I listen to an internet radio client (XM Radio) that doesn't have any EQ control.*
    *I know Audio Hijack can do this. But I'd rather not run a whole other application on top of the radio client just for EQ."* (original post from Feb 20, 2007 5:07 PM)
    I can't believe that almost 2 years later, there is still no system wide equalizer in OS X, working always, like, while watching YouTube or whatever. Yes, I know there is Hear now, but both apps, Hear and Audio Hijack Pro, are expensive and overkill for the simple ability to change some equalizer settings. A preference pane would be much better.

    I found a system wide EQ along with mixer and many other functions it works great its called Hear this is the web sight http://www.joesoft.com/products/hear.php

  • Why Wont Apple Fix AUDIO / VIDEO Sync Issues

    This has been a problem for awhile. Thank god there is a application fix but im receiving an iTouch very soon and I'm not sure if the same problem is going to be on that to..
    It might be how Quicktime reads .MP4 and .M4V Files but i can play the videos on VLC and Zune Software fine..
    I see other people posting this exact same problems. I see no answers... Apple Knows this is an issue. Why wont they fix it.
    From what im hearing it is the audio that is going out of sync from the video.
    Now my Final Question is
    "Is this just a Software issue for the computers or is it also a Software issue (Assuming that quicktime is the software on these devices) for the iTouch / iPhone ?

    well i got my itouch today and it seems that the audio and video sync issues are only on the computer distributions of quicktime and not the hand held device versions

  • Audio / Video Syncing Issues

    Hello Everyone,
    I own a 2011 MacBook Pro with a 250GB SSD and 8GB upgraded Ram. I'm currently using iMovie to create an hour long movie with images / audio / and voiceover in certain sections.
    I have been working on this for quite some time and would like to be able to export it the same way I'm able to view it inside the Application. However, when I export the movie the audio / video / voiceover is off and it does not match with what I have worked on inside the project.
    I have also tried breaking down the movie and exporting it in sections but the audio is still not syncing correctly on the export.
    Please can someone help me out and help me explore my options.
    Thanks in Advance,
    Mauricio

    Sorry for the confusion. To clarify:
    The Video and Audio are OOS. Let's say that at the beginning of the Clip, the difference is ~ 12 frames off. Is it still that ~ 12 frames off at the end, or is it now ~40 frames OOS?
    Though the best is to Capture with no OOS issues, the former is fairly easy to fix. The latter takes more work.
    Also, whether the OOS is constant, or dynamic, might lead to figuring out where this issue is being introduced.
    Good luck,

  • Audio/video sync with h.264 - players affected

    Hi there,
    I've been trying to do a sound mix in Audition CC and have been sent a video reference (h.264/AAC). I noticed the audio going out of sync with the video and so checked the file in a few players (PotPlayer, VLC, Quicktime). I found video was also lagging behind the audio with all these players so I was about to contact the person who sent me the clip but decided to do one more test. Weirdly, in Window Media Player the video stays in sync all the way through!
    I understand this means that my problem's more to do with my system than Audition, but I find this problem occurs sometimes in Premiere with other source clips too and instead of tweaking it to work temporarily as usual I really want to get to the bottom of it.
    I tried using AME to encode to different codecs and have tried uncompressed video and audio. This makes no difference, and I imagine that's because all my Adobe software is using a dodgy codec to read the video, could this be the case?
    Has anyone else had an issue like this? And why is Windows Media Player suddenly the only thing immune to this problem?
    Here's the mediainfo for the clip in question, thanks for any help!

    Hi,
    When encoding live in H264 with the FP 11  then playing it live on another client (through FMS r) the video sometimes (1/3 of times) has major skips or jerks. It's almost as if the video goes back to some older keyframes and then returns to live. Same experience with non-h264 produces smooth video.
    If the server (FMS ) records the video, the replay looks smooth, which is strange because I would have assumed the FP was not encoding well with H264.
    Has anyone had this issue? please reply
    Thank you.

  • Audio/video sync macbook

    I have a very strange problem. I have made a movie in FCE and exported it as MPEG-4 (1280x720) - audio as AAC 44.100 kHz using Quicktime Conversion.
    This all worked fine and it plays correctly on my mac pro running 10.6.4 with the latest QT.
    I copied this file (as a zip - over wifi) to my wife's macbook also running 10.6.4.
    The copied file in her QT runs with the audio out of sync and about 2 or 3 seconds in front of the video. Why would it play differently on her machine to mine? Very odd. However if I play it on VLC on her machine it plays perfectly.
    It is a wedding video that I would like to distribute to the family.
    How can I make it so that it plays ok on any machine?
    Any ideas?

    it's impossible to sync the computer get 100% no indication of the progress of the movie and audio on the tv
    the tv itself can keep it in sync
    but for the computer or ios device speaker to be able to sync it too the tv would have to feedback sync info all the time to the computer
    current systems does not support that
    same deal with bluetooth speakers and the likes the computer or ios device can assume that the audio is istant but in the real world there is audio proccessing which take a bit of time
