Sync'ing iPod Audio to Digital Video

I recorded a speech recently with two HD digital cameras, recording at 29.97. The video tracks sync'd easily. The speaker wore an iPod Nano with a microphone. The iPod output an m4a file, which sounds great, but is out of sync with the video. It starts out fine, but after about 3 minutes, the difference is noticeable. At 20 minutes, the audio is over 1 second behind the video. I have tried re-sampling the video in Soundtrack Pro, Soundbooth, and Audition. Nothing is working. What can I do to correct this?

It's a common problem when trying to combine non-timecode and non-trimeframe based media to precisely timed video formats.
Select the video track and examine its length. Write it down, accurate to the frame.
Select the audio track and select speed adjust. Enter the length of the video track. Render.
The small variation in pitch should not be noticeable. If it is, do the adjustment the other way by changing the length of the video track to match the audio. Thsi will impose a clearly visible hiccup in the frames on a regular interval but people tend to gloss over weird video these days; they've been numbed to bad video over the Net.

  • Problems sync'ing iPod with iTunes

    I purchased some episodes of The Office through iTunes recently. Initially these episodes appeared on my iPod after sync'ing. Now, when I sync, the episodes will not transfer to my iPod. They appear in my iTunes account, the checkboxes are checked, but I can't get them on my iPod.
    Has anyone experienced this before? Any thoughts?

    Disregard.
    I found an option in iTunes where you can set the Play Count to zero. When this is set to zero and you sync your iPod, all content appears on your iPod.
    Not sure if this is the best solution, but it works.

  • Exporting video for iPod - audio OK but video is "white"

    I know this issue has been raised before but I cannot find a clear resolution anywhere - happy to be pointed to the right place.
    Some time ago I converted some old VHS home movies to DVD and they play fine. To view them via AppleTV I've converted them to MP4 using H.264/AAC via MEGUI, and they work fine in iTunes on the PC and on AppleTV.
    Once they were in iTunes I tried converting them for iPod but the output is a blank white video screen though the audio is fine.
    To diagnose the problem I tried loading the MP4 version directly into Quicktime (Version 7.6.8)where the play fine. Then I tried exporting them for iPod and I get the same white screen plus audio.
    I've seen this issue dismissed as due to some form of DRM but I doubt that is the case here. The video is my own, the DVDs I created are not CSS protected and the MP4s are also unprotected.
    I've also seen it attributed to a missing codec, but that is unlikely given both iTunes and Quicktime play the videos without a hitch.
    Any clues on how to proceed?
    John

    Last post before I leave things alone for a while.
    I've uninstalled and reinstalled iTunes and Quicktime and iTunes no longer chews up lots of CPU when trying to convert one particular Quicktime created file.
    I've also recreated each file again from the same source, the AVI encoded as DV-PAL with screen res of 720x576. I created a series of test cases to try to pin the problem down and I think the best exposition is the following -
    The problem
    An MPEG4 file exported from Quicktime loads and plays in iTunes, plays on AppleTV and can be converted for iPod.
    An almost identical MPEG4 file created by MEGUI using the x264 encoder, latest build 1649, and all the same settings as Quicktime loads and plays in iTunes, plays on AppleTV but when converted for iPod produces a file with audio but the video is "white". Looking at the file size, less than 2mb, it is pretty obvious that the video stream is simply not there.
    Clues
    Quicktime Movie Inspector reports the screen resolution of the file it exported as 720x540 while for the MEGUI created file it reports a very odd 787x576. Note that Windows Media Player and YAMB (MP4Box utility) both report this same file as 720x576 which is what I would expect as MEGUI did not resize the video. As an aside, WMP and YAMB also report the Quicktime created file as 720x540 so they agree with Quicktime on that score at least.
    Obvious Question
    Why does Quicktime report an incorrect screen resolution, and is this contributing to the conversion problem in iTunes?
    My understanding is that MPEG4 uses 16x16 macroblocks and so the dimensions of anything to be encoded must be in multiples of 16 and 787 is not a multiple of 16.
    Of course, the 787x576 screen resolution could be a red herring.
    Details from Quicktime Movie Inspector follow:

  • Sync ing  iPod to more than one computer?

    Am I able to sync my iPod Touch 4th generation to a 2nd computer with iTunes, or will I loose everything on the iPod?

    You can only sync with one computer/iTunes library.  However, you manage music with more than one computer..  See:

  • "Sync"ing ipods

    My computer recently crashed, and with it's demise I lost all of my song files. I got a new computer and was able to retrieve all of my itunes purchased music, but a lot of my ipod library was a collection of borrowed cd's and whatnot. My question is: "Is there anyway to sync my ipod with a new computer and not erase all current music?"

    Check out the instructions/suggestions here.
    Music from iPod to computer.
    There's also another method. I've successfully tested this across several different Windows PCs.
    Open iTunes and select edit/preferences/advanced/general. Put a check mark in the box marked "copy files to iTunes music folder when adding to library" and also "keep iTunes music folder organized", then click 'ok'.
    Connect the iPod whilst holding down the shift/ctrl keys to prevent any auto sync, and if you see the dialogue window asking if you want to sync to this itunes library, click 'no'.
    Then go to file/add folder, open 'my computer', select your iPod and click 'ok'.
    The music files should transfer to your iTunes.
    If this doesn't work (and it may not because officially it's not supposed to), there's Yamipod. This is a free program that transfers music and playlists etc from iPod back to the computer. However, it does not transfer playcounts/ratings etc.
    Borrowed cds? Tut tut.

  • 60GB 5g iPod Audio Problems on VIDEOS only

    I've been looking all over the web for a solution but haven't found anything acceptable.
    I'm using the latest version of iTunes, G5 iMac, 1 GIG RAM, System 10.4.5.
    While my Music sounds great, my videos do not. Volume on Videos is adequate but not loud enough to block outside noises (if a subway passes by, I can't hear my Videos at all).
    I've tried the option tab in iTunes and raised the volume slider all the way to the right (100%); I've tried "iPod Volume Booster" and "gopod". None of these utilities help.
    While extracting DVDs in Handbrake I also use the higher audio settings: 48000 Sample Rate, 160 Bitrate. Results are still as I describe above.
    Any other suggestions? Any way I can increase volume as I'm extracting videos (I don't see any such option in Handbrake)
    Thanks in advance for any help.

    Not answered, just removing.

  • Sync of recorded audio and FLV video.

    Hey guys,
    I'm having a major problem. I'm trying to create a project
    that involves recording audio based on a video and then playing
    them back together in sync. The recording is sent to a Flash Media
    Server and the video comes from a local file.
    When recording starts I create the netConnection and
    netStream respectively. I then create an onStatus even for the net
    stream so that what the status code == NetStream.Publish.Start the
    video begins to play.
    Then when I play back the recording I create an inStream for
    the newly recorded file to play through. Once its onStatus event ==
    "playing" the my local video file starts.
    To me this all seems logical but there are obvious sync
    issues. I've managed to capture a delay between my initial call for
    my outStream to publish and the time that it actually sends the
    onStatus event. I've tried thinking of ways to use this data to
    affect my playback but nothing has worked right now.
    Hopefully someone out there has worked on a similar project
    or at least has experience with these types of things.
    Thanks so much in advance,
    Mr. PinC

    I have been searching the internet for days on a simple, standard answer for my problem. I am shooting video using a Canon 5d mark II and recording audio separately using an Olympus LS-10.

When I try doing it manually, the audio from the Olympus seems to be in between frames and I cannot line them up exactly.
    I exported the movie files through MPEG Streamclip to Apple DV/DVCPRO-NTSC, 720x480(DV-NTSC). I converted the audio files in Itunes to AIFF files at 48khz and 16 bit stereo.
    What are the exact settings I should be using for the video and audio?
    Do I need to change the frame rate of the video?
    Do I need to change the sample rate or speed of the audio?
    Is there a way to slide the audio clip in between frames?

  • Need help sync'ing iPod Touch (not authorized error)

    I have an iPod Touch (about year old not sure if 4th or 5th Gen), iOS 8.1.2.  I used to be able to sync everything fine with Windows ITunes on my old desktop, but when I got a new desktop I can't sync (more precisely I can't "Apply" updates to apps).  When I go to the device's Apps tab on the left of ITunes interface, I click the "UPDATE" button on an app (Temple Run 2), it changes to "Will Update", then I click "Apply".  During the sync it says
    "The iPod "name" could not be synced because this computer is no longer authorized for purchased items that are not on this iPod.  To authorize this computer fro items purchased from the ITunes Store, choose Store>Authorize This Computer."
    I know this question has been asked by others, and I've tried many things including deauthorizing and reauthorizing, going into hidden files and deleting the SC Data folder, signing in with another of my ITunes accounts, using the "Manage Deivces" section of My Account, etc.  None of it works. (Note: In Manage Devices, I see the iPod in question, but I renamed recently and it still shows as the old name in "ITunes Manage Devices" - I am afraid to delete it and add it back under the new name because I don't know what good or bad would happen if I do)
    So, is there another idea out there?  I would do a hard reset on the iPod, but I am afraid I;ll lose all the data for each app, especially game progress.
    Any ideas to troubleshoot this?
    Thank you,
    Mike

    Yes, thanks, that's one of the first things I went through.  Did all the Windows-related steps there and still have the same problem.

  • How do I sync my iPod without grabbing the Video Podcasts from my iTunes?

    Hi,
    I have searched and could not find the answer to this problem.
    Anyway, I have a 5th gen iPod and am running it on a Mac with the latest iTunes. On the iPod options pane, I have selected to update only the selected Podcasts. I am leaving the podcasts that I do not want on my iPod (but want to keep on my Mac) unselected.
    Now although it is true that the unselcted Podcasts to not appear in the Podcast section of my iPod, the files are still there and can be found by artist, album, etc.
    How can I get around this? Basically, I have a few gigs of Video Podcasts that I do not want to carry on the iPod but do want o keep on my Mac in iTunes.
    Any help would be appreciated.

    Try going into iTunes preferences and click on the iPod icon (pod has to be linked up) and choose to "manually" update iPod. Will this help?

  • I have an iPod Touch with 5.0.1 and iTunes with 10.5.1.42, and the problem is the syncing process. One of my videos won't get synced not matter how much I try. Other videos works. Any tips?

    My iPod is the 3rd generation and it is running 5.0.1, and the iTunes I use is 10.5.1.42 for Windows. When I started syncing my iPod to include one video, iTunes will work fine, but when it is finished, I checked the videos on my iPod and found out there wasn't. I went to the iPod section, and under the movie subsection, I even clicked the video I want to be synced, and clicked on APPLY, then sync. When I tried doing it over the air, or usb, it just won't work. The diagnostic for iTunes says it was all right, nothing wrong is going on. I rebooted iTunes and my iPod several times, nothing! Any tips!???

    Does the iPod work OK?
    Does it charge when connect to the computer?
    Does it appear in My Computer?
    Look at the dock connector on the iPod. Compare with the iPod that does work/connect.
    I suspect you have a 2G iPod. Those can only go to iOS 4.2.1

  • Synching a separate audio file with video

    Hello, I was hoping someone might be able to help.
    I have a video file but I am trying to sync a audio file to the video.. Not the video's original audio recording but a different file. Basically I have a recorded live band performance and I also have a direct out audio recording of same song (which is better quality than the video recorders internal mic) I want to sync the direct audio to the video.. The biggest issue is the tempos of the video and the direct audio recording are different. Can you set the tempo of the video file to the audio or vice versa? Can this be done in FCE or is this something for Logic Express.?
    Thanks for the help

    This is a BEAR!
    First need to know much more and even then, oh well...
    (a) You say the sound from the board has a different "tempo" than the sound from your on board Mic. or camera. Were both recorded at the same time and place? (b) When you say "tempo" do you mean that when you import the sound from the board (that was recorded to a CD?) into FCE and place on the timeline that the synch "drifts"? (c) Are you first finding a common "synch point" to begin with? (d) Your camera was set to 16 bit 48 kHz, right? What are "the properties" of the sound from the CD created on the board?
    If you are indeed finding a common synch point - that is, if you are synching by eye and the synch then "drifts" because the 2 have different "properties", then you will have to either use a cutaway every time you re-synch by eye to a common "cue" or use a D.A.W. or sound editing program that allows you to import a "movie" and has speed and pitch controls that you will have to constantly tweak. This is a formidable undertaking even for a pro but can be done. Say you do that, tho. This "tweaking" will change the quality of the sound at best and sound "wavy" at worse, so...
    bottom line - I'd try to enhance the sound you recorded in camera with filters and an equalizer in any DAW that you can import a "movie" into like Garage Band or just do it in FCExpress itself and learn that next time you are shooting a live musical event, plug your camera into the board to begin with... via balanced cable. Careful to tape your XLR cable run down well.
    Maybe a sound engineer might be able to help more. Ask on a Pro Tools or Logic board?
    Good Luck -
    B.S.

  • Cant hear audio after converting videos for ipod

    After i convert any video i have with itunes, it loses the audio. does anyone know how i can fix this so i can watch videos on my ipod with sound

    QuickTime expects video files with separate video and audio tracks, but many MPEG formats used a muxed (multiplexed) single track that contains both. Therefore, when you convert videos in iTunes to iPod format they only show the video and no sound since iTunes (really QuickTime) is not looking for the audio track within the video track and it gets lost.
    iPod plays video but not audio of some exported files
    http://docs.info.apple.com/article.html?artnum=302588
    One way to work around this is to use MPEG Streamclip to convert the files to fix this issue...

    but there are other applications besides MPEG Streamclip you can try as well.

  • I tried to sync my iPod touch to a new laptop and it deleted all of my music and videos. I called tech support and they told me to email iTunes and they would give it back to me. How do I do this??

    I  tried to sync my iPod touch to a new MacPro laptop and it deleted all of my music and videos. I called tech support and they told me to email iTunes and they would give it back to me. How do I do this??

    Correct. When you update via iTunes all synced media that is not in your iTunes library will be lost.
    As IO said before:
    You can redownload most iTunes pruchases by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store
    I do not think it included audio books.
