audio and video out of sync on some readings

I just started on a few Web sites have a problem when I stream movies. The audio is not synchronized with the video. I have experienced a few times in the past and could stop playback and restart to fix the problem. Which is not solved the problem now. I keep my empty cache, so this isn't the culprit.

It is only on a few Web sites and they have always played fine before. How to track down the problem?

  • Audio and video out of sync in first after importation


    I've seen a lot of discussion threads on this site and others on the subject. I shot some videos on my iPhone 6s and wanted to compile it to Premiere CS6. When I watch the video on my phone, VLC or QuickTime Player, the audio and video line up perfectly. When I import it in preview the sync audio and video download very out of wack. I tried to convert the video in .mp4, .mpg, .mxf file formats, and nothing does the trick. I tried to use the hand brake to apply a constant rate, but not luck. Does anyone have a solution to this?

    Data sheet:

    CS6 6.0.5 Adobe Premiere version

    16 GB of RAM

    a lot of free space on the hard drive

    Thank you


    If you go to the movies on a cell phone from Apple, you may need to use an Apple program for editing... have you looked at Quicktime Pro?

  • Audio and video out of Sync

    I capture images from video game using ShadowPlay recording at 60 fps mp4 files. When I import into first and play in the sequence, the audio and video are out of sync. When I play in VLC or Windows Media Player, the timing is perfect.

    Why first plays the audio and video synchronized?

    The corrections that I found online that does not solve the problem are:

    -Make the video in the work area bar (it actually makes it worse for some reason any)

    -Edit video in .mov file extension

    -I know how to use Handbrake to make the files before import has also been suggested, but I don't want to have this extra step added to my workflow, it should not be necessary.

    Any help on this would be greatly appreciated.

    Also, is there no other way to get around the problem of variable frame rate?

    Not if you use the GPU hardware to capture your h.264 videos, there isn't.  First can not correctly handle variable frame rate images.  And the images only you're going to get your encoder is VFR.

    You have 3 basic choices:

    (1) stop using ShadowPlay and use something else which will tax your system more to capture video in a constant frame rate format.  There are other applications that capture images CFR, generally in AVI format, and the resulting files are massive.  You will have a drop in performance in the game when you use these applications.

    (2) transcode w/parking brake to the CFR

    (3) use a different NLE.  Sony Vegas, from what I hear, will support VFR without problems.  Most other NLEs will not, including Premiere Pro.

  • Audio and video out of sync after rendering


    I already asked a fairly identical question like this, but I have some news:

    First of all, my problem is that after the export of the audio and video is not synchronized as in the scenario. Well, many have told me that he deals with variable frame rates, because I have images is 25 frames per second and sequences with 29.97 fps. But normally first would have changed directly each element in my sequence (25 fps, 1920x1080p) settings. And later when I add the clip in MediaInfo, he also tells me that the frame rate is 25 fps constant, not Variable. So I think that this is not yet the problem more.

    But now, here's a little 'story': when I open the video after the return of his perfectly synchronized WITH the VLC Media Player (and not Windows Media Player).

    And my question is: how is this possible? Couldn't, I now just change the Standart to VLC Player and then upload it to Youtube with the normal sync? What is the difference between windows media and VLC media player in this case player? Maybe it's because I have a few Quicktime footage in my sequence, which can be read with VLC Media player and not with windows media player?

    If you have any ideas, let me know!

    Thank you

    You basically answered your own question. VLC has proved to be more versatile and superior then the WMP.

  • audio and video out of sync in first pro cc 2015, player QT video on a mac mini

    So, I use Adobe Premiere pro cc 2015 to change a screen capture video recorded with quicktime player. I'm on a mac mini with OS X el capitan, and it was my first time using first (so I probably just doing something wrong because I do not know the program, but anyway, I imported the video into the first, (it's a .mov file format) and the video and audio are out of sync) so I thought ok, I can simply detach the audio, move it above, the re - attach it, right? so I found a part of the video that has been easy to match the audio and video, and I lined up. Everything was perfect until I went to other parts of the video and realized that they were always out of sync. Apparently, the video is at a different speed or format or something as the audio, and even if I have lined up on the one hand, the other parts are always out of step. I looked at how to fix, I messed with the project settings, then tried to change a .mov to a mp4 (because a mp4 file that I already have on the computer was functioning very well in first) and finally, as a last effort, I downloaded version 2014 so and NEITHER VERSION WORK they both the same number.

    If someone can please help me I WILL BE so HAPPY and thanks a lot in advance

    I am really sad because I'm upgrading to use iMovie (ugh) and I was so excited for the first time and now it is messed up, and I'm really disappointed.

    If it makes a difference, the microphone that I use is a blue snowball ice I bought a week ago (WEEK AGO) haha

    None of the parameters of creation, or QT player or something that might help is very much appreciated.

    Thank you, Owen

    Thank you very much!! I finally found out with the help of the family, but I thank very you much for help!

  • Audio and video out-of-sync clock at 00:00 in "Adobe Player.

    Video jumps backward and forward, the error window appears. And audio, of course breaks in and out. I tried to start with a new project. Fell to a simple piece of video in the project which had NO audio - always get the error and playback jumpy.

    Of course, I wish I had not being updated, but it's too late now. And for the first time that the process REMOVED upgrade my 2014 version-, really sucks for my production schedule

    How can I get CC 2014 Back!

    premiere Pro CC 2015 Error.PNG

    Hi all

    There was some success workarounds for this problem. You can:

    * Disable the input device listed in default of entry via the Device Manager (so that the default input device is "No. Device") available.

    * Change the entry to something like line or microphone input device and a device and then connect this entry (even a pair of headphones will usually work for this)

    * Alternatively, install Asio4All to provide an alternative to the MS driver listed under device class.

    These options have been used successfully to solve this problem. The Premiere Pro team knows and is actively working to resolve this issue. If all goes well they'll have something soon!

  • Why do my audio and video start in sync, then move quickly out of sync?

    I have just installed Windows 8 and have also ordered: 12 items first.

    I also have Windows movie maker.

    When I play my clips in Premiere Elements, they audio and video synchronized early, but quickly get out. This does not happen with Windows Movie Maker and I had tested a few videos NCH also editing software and do not have this problem.

    can someone tell me what I have to do to get this working right?


    For troubleshooting purposes, assume that the video is characterized by a variable instead of a constant rate.

    1. download and install the free program of handbrake.



    Import your video 1280 x 720

    Then, where it says "Chapter", I put for seconds


    Locate, and then set your backup location for the file to process



    Picture tab

    Leave as is

    Video tab

    Video codec H.264 (x 264)

    Framerate (FPS) 23.976

    and point next to Constant Framerate

    Press start at the top right of the workspace

    Wait for 'Queue finished' in the progress bar in the bottom left of the workspace.

    Then determine if this H.264.mp4 file works for you in Premiere Elements project set the project preset manually set the



    AVCHD LITE 720 p 24

    This should rule in or out a possible variable rate being at the heart of the problem.

    Thank you.


  • Imported audio file related and video out of sync

    I have video and audio in Mixcraft, export it to an .avi file, and then import it into APE8.  For some reason any video and audio is out of sync way every time.  Any suggestions?  Thank you for always!

    For sustainable development projects, MS AVI with CODEC DV/DVC is the right to choose. There are very, very little to gain with the AVI uncompressed, except much larger files.

    Good luck


  • Premiere Pro CC 2015 video / Audio won't play - Out-of-Sync Audio and video clock errors

    After the installation of Premiere Pro CC 2015 I am unable to actually play my video in the timeline.

    I must point out that the same video and audio files accurate work perfectly in my previous version of CC 2014.

    Usually when I hit the play button nothing will happen and then after a time it will stutter back and fourth between a small loop (no audio present) and give an error that says "clock Audio and video out-of-sync (instead of time) in"Adobe Player.

    I tried full uninstall and reinstall Premiere Pro CC software 2015 without success. I also tried to delete all the preferences of Premiere Pro to my settings user without success. I should also mention that after effects CC 2015 is oddly also often send me errors do not have enough executives, so I'm not sure if they are related. Once more, the CC 2014 version works perfectly.

    For reference the video file is a .avi with Xvid compression and sound is a .wav. These have always been used exactly the same with CC in 2014 without problem.

    I also ran a full virus and malware scan just in case for some strange reason, that was at fault, and I ran into zero issues. Media Encoder, Photoshop, and Illustrator CC 2015 that all seem to work great.

    I am quite technically savvy and this one left me speechless, that really stinks that I was looking forward to the potential improvements to speed updates. That's life.

    Thank you.  In 2015, CC, you can click on the settings... button in the Audio hardware preferences.  Then in the record of the OS dialog box tab, you can disable manually (for example, right-click and choose the appropriate option) the SPDIF input.  It is only a temporary workaround until get out us a patch with a fix, but let me know if it works for you.

  • The audio files are out of sync with video clock?

    I record an audio book with premiere pro 2014, is therefore a larger file, then Adobe switched me to first pro 2015 and now it says that my audio files are out of sync from the video clock. I realize Adobe has no technical support so I googled a cure. They told me to remove CC 2015 and reinstall CC 2014. Of course, Adobe's download anything over three days old extremely difficult unless you are following specific steps that are simply in place to harass. Try as I could, download CC 2014 cannot be done. My question is this: How can I re - sync my files using only CC 2015? What is the best way?

    * UPDATE. Problem found! It turns out that when I opened my task manager my CPU or central processing unit, was filled to 99%. I just had to uninstall some programs needed and things much better brought.

  • Audio video out of sync once imported into Encore CS6

    Hi all

    I am having some problems with Encore CS6 on my iMac with OS X 10.9.5.

    I'm burning a few videos I captured off the coast of the VHS using Elgato Video Capture. He outouts as .mp4 files

    The videos play fine on the outside, but as soon as I import them into even the audio becomes out of sync. I burned a lot of VHS to DVD and for some reason that the problem appears to be new.  It out of sync in the timeline, listen to excerpts and once burned.

    I even tried using Adobe media encoder to convert the .mp4 to MPEG-2 outside again and the audio is always out of sync. I even tried to cut a bit of the audio to the front because it seems to be just a little bit slower, and it worked for the first 5 minutes, then he again not synchronized.

    Does anyone have an idea as to whats going on? Or has experienced this problem?

    Thank you


    And you can see here that my proposal was wrong. This is a variable rate. You need convert this file in constant cadence. I suspect that John may have a link to a converter. There are many more threads about that in the Premiere Pro forum.

  • Binder/sync Audio and video

    I think I'm right on the right edge if this can work:

    I have a rough cut of a few clips using audio on the device. I also recorded with a separate audio recorder. I want to sort a secondary audio link to the primary audio and video clips from the source, so that the secondary audio will be added for the first mounting without having me to go and re - synchronize each change with the corresponding secondary audio. Is it possible to sync the audio added in a source file and have a reflection in an edited sequence?

    Aligning each camera with audio clip associated with its own sequence, then changing using these sequences rather than the original clips is one of the best ways to proceed in the light of your starting point.

    Audio drift should not be apparent on reasonable periods of clip (for example, up to 10 or 20 minutes) depending on the stability of the clock in the audio device.  Many reports were due some manufacturers using audio rates slightly non-standard who first then supposed to be correct and therefore generated out-of-sync issues for about 30 minutes or more.  Not your problem here.

    If, when you check the sync audio on a full clip, you know it's OK at first but in the end, then setting a marker for both video and audio at the end and using the rate stretch on the audio to change its length by a small amount to align the markers should give good enough sync for the clip.
