Video and sound are out of sync

The picture and sound my Apple TV are out of sync by several seconds. THese are on items that have been copied to Apple TV as opposed to streaming from iTunes. Anyone have experience with this? What's the solution?
Thanks.

What format were the original items ?
What frame rate are they in the original ?
What format are they on the AppleTV (H264 video AAC audio is the most common, but there are others) ?
What is the video frame rate now ?
Most out of syncs come from an imperfect attempt to encode for AppleTV. ie. DVD frame rate is 29.97fps. Many encode this to 30fps. So the movie plays 0.1% too fast, too little for you to notice, but at the end of a 100 minute film, the audio is 6 seconds out of sync with the video. Or 3 seconds on a 45 minute TV show.
Also check the source. I'd had DVDs (Alien Resurrection) jump 10 seconds out of sync in the middle of the movie. Back to the shop for that one.

  • Video images and sound are out of sync

    Hi, I'm new to videocasts so please forgive me. I have a few video podcasts that play fine in iTunes and in other iPods but audio and images become out of sync when I play it on my Nano. Does anyone have any suggestions?

  • Video and sound slightly out of sync when screen mirroring

    When I start screen mirroring and play a video, then my macbook screen matches perfectly with the sound output from my stereo, but my tv is slightly delayed compared to my macbook which makes the sound and video out of sync. it is something like 1/10th or 1/20th a second, but it is extremely annoying.
    Anyone has the same problem or knows how to solve this?

  • The video and audio are out of sync while watching movies with iTunes

    I have searched for an answer everywhere but haven't found one yet, so if someone could please help.

  • Video and audio are out of sync

    I have the Dell Venue 8 pro tablet running 8.1.  After downloading video from itunes, it plays fine but the audio and video quickly get out of snyc.  Any ideas?

    First thing to check is the audio rate:
    Are 32 kHz clips going to an FCE 32 kHz Sequence?
    If the exports are 48 kHz, is the Sequence matching at 48 kHz?
    Seqeunce settings are governed by the Easy Setup chosen when you start a Project.

  • N95 Recorded Video: Video and audio is out of sync

    Audio and video is out of sync when I play videos recorded with N95 on my PC. If have used different PC applications to play the video, but all exhibit the same problem.
    In the beginning of at video it seems that the audio is about 400milliseconds ahead of the video - you hear the sound first. The different in audio and video is not constant. In a long video (30-50minutes) it is quite unpretictable how video and audio is out of sync in the end.
    To experience the problem yourself record a long video sequence with a N95.
    1 .Record something where it is easy to see if video and audio is in sync.
    2. Transfer the recording to a PC.
    3. Play the recording using VLC (www.videolan.org)
    Another way to experience the problem is to convert the recording to AVI format at play it in MediaPlayer or WindowsMovieMaker. To convert a N95 video recording to AVI format use Mp4Cam2Avi.
    http://sourceforge.net/projects/mp4cam2avi/
    The video recording settings I use on my N95 are:
    Best Quality
    No Video Stablisation
    Firmware version 21.0.0.16.
    I think the video quality of N95 recordings is quite good, so I would really like to be able to view and edit the recorded vidoes on my PC.

    You can edit videos on your PC, just converting them to AVI then using any Video Editor on the PC.
    Yes while editing separate the audio channel from the clip and reinsert at the begining of the clip. This will minimise sync issues.To get accurate sync increase the timeline so that you are able to the see audio squiggles as a waveform.

  • Video and audio goes out of sync when imported into Premiere

    I have some videos ripped from some DVD that an acquaintance made, with an open source program called HandBrake, with the default "high profile" settings. When I play it both in VLC and in Quicktime, it plays just fine, but when I import it either in Premiere or in After effects, the video and audio goes out of sync (the video ran faster than the audio and when the video stops, the missing audio is trimmed).
    Video info according to Premiere (in Spanish but you may get the meaning).

    "HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10.  HandBrake is migrating to quality-based encoding."
    Hmmm.  I use HC Encoder to make my DVDs because it's the only free encoder I've found with the much more professional Constant Q encoding option.  But HC Encoder doesn't do HD sources for Blu-ray, so I've been wondering if I'd be stuck with the lame-*** consumer CBR and VBR options most encoders provide (including Adobe - hint, hint) when I eventually start working in HD.  This is a very interesting program, Handbrake.  I will have to check it out.

  • Why are my imovie video and garageband track out of sync?

    Hi
    I'm currently making a video of an original song for youtube. I've been recording the video in imovie and the audio in garageband.  I mixed down the audio in garageband and imported it to imovie. I lined up the audio with the visual at the start of the track, only to find it gradually goes out of sync with the video. I tried a different approach, syncing up the video and audio at the end of the song. I went back to the start of the song to see how in sync it was and the audio started way before I open my mouth! Unfortunately imovie did not record any sound, so I can't use the imovie sound to sync it.
    I have literally no idea how the video and audio could be going out of time! I have one video and one audio track, so it's not a mix up.
    It is totally bizarre and I wonder if anyone could suggest what's caused it/how to solve it.
    Thanks
    Vic

    First do not use the Share ➙ iDVD menu option in iMovie.  Use the Share ➙ Media Browser.  The former loses considerable quality in the shared movie.  Drag the movie from the Media/Movies pane in iDVD into the iDVD menu window.
    Follow this workflow to help ensure the best quality video DVD:
    Once you have the project as you want it save it as a disk image via the  File ➙ Save as Disk Image  menu option.  This will separate the encoding process from the burn process. 
    To check the encoding mount the disk image and launch DVD Player and play it.  If it plays OK with DVD Player the encoding was good.
    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

  • When I trim a Video in QTpro, the video and audio become out of sync

    I use mpstreamclip to export video to mov or mp4 files. When I load up on QT pro and then do some trimming, the resultant clips often have audio and video that are slightly out of sync.
    Can anyone provide some guidance on what to do?
    Thanks so much.
    Skip

    I think it is going to be a problem with the fps setting on export. If you entered 30 fps as the setting for export and you found the result had the audio getting further and further ahead of the video the longer you watched it may be that you needed to enter a frame rate of 29.97 fps to keep things in sync. I am doing similar tests on some conversions because I have had sync problems as well. I will repost when I check my current export at 29.97 fps.

  • ITunes 10.5 video and audio getting out of sync

    Hi,
    my iTunes videos (bought from the store) are getting video and outio out of sync.
    I found some hints to turn options in QT but iTunes 10.5 doesn't use QT - isnt'it?
    Any ideas to solve this problem are welcome.
    Yours Rüdiger

    Hi and welcome to the forum!
    First of all, don't convert the file to a MP4. What exactly are the specifications of the MPEG file you are using? It would help to know the frame size, frame rate, and the audio rate.
    You most likely placed a 32kHz clip in a 48kHz sequence or vice versa.

  • Video and audio fall out of sync in Captivate 6

    I made a great little video demo in which I added audio while I recorded it in Captivate 6. However when I play it back the audio and video fall out of sync. How can I fix my problem and how can I prevent it from happening again?
    JJ

    Douglas, I found that even the SWF files have started to get out of synch as well (although not as badly as the MP4), so with Adobe's blessing, I installed Captivate 7 on my 2009 model MacBook Pro (with Windows 7 running in Bootcamp) and now when I publish both SWF and MP4 projects, they are in perfect synch. 
    The strange thing is that my MacBook Pro probably has less grunt than my work PC (Dell Lattitude) and I would also have thought that running in a Bootcamp based Windows 7, that would detract even further from Captivate's performance. 
    I am happy that this solves the synch issue, I am not happy that I must continually move projects between my office PC and my home based MacBook Pro in order to do this and I am still none the wiser as to what is actually causing the problem; although I do wonder whether it is in some way related to the reporting to base issue that was causing Captivate 7 to go into a not responding state every few minutes (that was resolved with a patch provided by Adobe support)..

  • After months, my loops and metronome are out of sync

    I searched but couldn't find this: added some tracks to a metronome track, played them back and they are way off. I've recorded hundreds of tracks and they sync up no problem, added loops, still no problem. What could I have done to make everything out of sync? I can't record anything now.
    Must be simple thing but 'sync' in HELP search produces nothing. Not sure what to look for.
    Thanks

    Been awhile- thanks for your reply. It just happened again. I moved a drum loop, changed the tempo. Then I added tracks and they are not syncing up with the drum loop. Each subsequent track appears to be in the same tempo as the drum loop.

  • Video and audio are not in sync. How do I fix it?

    I recently bought the Adobe Premiere Elements 11 Video Editing Software and after using it one time most of my videos are not synced with their audio. The audio seems to be fine, but the video keeps on speeding up and slowing down. It is very stressfull. I would love to get back to my video editing as soon as I can. Please Help!

    If you want to merge Apple ID's - you can't do that. For reasons unknown, Apple just doesn't allow it. Passwords are are different story. You should be able to reset your password for any other the ID's that you have.
    Do you have multiple Apple ID's? And if this situation is that much of a mess, you might be better off contacting Apple in order to get it straightened out.

  • Video and Audio getting out of sync?!

    So I have Final Cut Express on my Macbook with 2.4 GHz, 2.6 GB RAM and I am running Mac OSX 10.5.8. I have a 30 minute mpg, which does not import into FCE, so I converted it to an MP4 via a converter. When I play the video in a standalone player (the mp4) everything is fine but as soon as I put it into FCE and render it, the audio starts to get ahead of the video as the video goes on. its fine in the beginning then by the time its 15 minutes in its a good 1/2- 1 second ahead, and gets even worse by the end. CAN ANYONE HELP?!
