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.

  • Why can't Adobe first Pro CC 2014 time remap Audio and Video together?

    In case you haven't noticed, my question is WHY.  I don't know why Premiere Pro can't do that.  What I understand at the moment, the only way to time remap audio in anyway shape using the software Adobe is Adobe After Effects, that my computer has no chance of ever being run through.  I know how to stretch a regular hearing and Premiere Pro audio, but apparently I can't time remap audio using these programs.

    So why can't Adobe Premiere Pro time-remapping audio with the video?  What is the reason that he can't?  It's a disappointment, huge and very impressive to see in the future.  If it is possible to time remap audio and video in After Effects, which is great and all, except for the fact that I can't use this program.  Why can't we do in Premiere Pro, and it will be always possible in Premiere Pro?

    In addition, audio time remapping will become possible in hearing one day?

  • Audio and video Shifted only in Premiere Pro

    Hello guys,.

    I'm having a problem with premiere pro with sync audio and video, which are stored in files separated by means of bandicam.

    These files are saved as:


    AVI Motion JPEG to the 720 p 30 fps


    Stereo PCM 48 kHz

    When I open the video file, via a media player like the one used by default on windows, I have no problem, but when I add these files in the timeline of a sequence in first pro, I notice that after some time (+-2 minutes), audio and video are starting to change and I don't really know why.

    In Premiere Pro, I tried the sequence with the video and tried settings with HDV 720p30. In both cases I had the same output two files moved after awhile.

    Someone knows how can I fix this?

    Kind regards


    Is bandicam media variable or fixed rate? If you don't know, drag & drop a file on the MediaInfo program mentioned here, go to TreeView and see if it's the VFR or CFR. PrPro do not play perfectly with the media of VFR. Which many screenshot recorders produce.

  • Satellite Pro A120: DVD/CD burner does not burn audio and video files


    I have the Satellite Pro A120 with a cd/dvd burner MAT * a uj-8415. It works very well with data Brüning, but...

    When you try to burn the MP3 files or video files on DVD or CD/r or any type of audio file, it suddenly gives me an error message telling me that the cd can no longer be used.

    I tried hole Sonic (RecordNow), through Nero 6, and also directly by dragging and dropping files, but all was in vain. This MATI * a uj-8415 machine has also made the same error while burning a DVD double layer.

    Again, the unit reads all types of CD and DVD and writes also all types of files with the exception of the audio and video.

    Can you help me please to solve this problem?


    I know that some mp3 files and audio are protected against copying and burning on different CDs or DVDs so could not work? ¦

    Other reasons why you can't write these files to CD or DVD is simply a problem of compatibility between the STRANGE and the CD or DVD.
    According to my experience, not all CD or DVD is supported, and these compatibility issues are not really rare.

    I also have another idea.
    Have you heard of burning of problems caused by the bad registry entry? I mean the upper and lower filters...

    Please check this doc MS:

    Completely remove the Upperfilters and Lowerfilters from the following registry key values:

  • Windows XP - installation of Realplayer changed audio and video icons

    Running XP Home on my laptop.  I installed Realplayer and all of a sudden all the audio and video elements icons have changed.

    I went into preferences/Options in Realplayer and Windows Media Player to select the default reader for WMP files, and while files now open with WMP, the icons are still those changed.

    In the past, the minute I change associations (i.e. the value of the default WMP player), the icons changed as well, but it doesn't now.

    How to restore the original icons, i.e. If a file is associated with WMP, how can I get the icon to show that it's a WMP icon?

    Thank you

  • Windows 7 audio and video stutter problem

    Recently when I watch videos (be it youtube, shake, DVD or videos on my hard drive) apparently at random my audio and video will be stutter.

    I tried to disable hardware acceleration, it did not help. I have the latest video and audio drivers (that I know) and it seems to happen more predictable when I run a software intensive treatment like utorrent, it is not get recorded by the recorder of camtasia studio or bandicam (first being a screenshot while the second is a game of capture) I tried to catch in the Act to make a short video to demonstrate the problem , but he has not registered. the video seems quite well with no stutter.
    I have: Windows 7 Home premium 64-bit
    graphics card: NVIDIA GeForce GTX 660 (tested by alienware benchmarking to work perfectly)
    Processor: Intel Core i7-3820 CPU @3. 60 GHz quad core
    Under "sound video and game controllers" in Device Manager there: NVIDIA High Definition audio.
    NVidia, Virtual Audio Device (extensible wave) (WDM)
    Realtek High Definition Audio
    All claiming to have the latest drivers when I have them check for them.
    My version of windows is up to date and I am completely baffled because I did not install anything new in the last few weeks, but this problem started about 2 weeks ago.
    What is my problem? Y at - he of the info, I did not think I should? If so let me know what and I will update this
    Update 1: this issue is still not resolved, despite the installation of codecs and update of the adobe flash player, I always get the question every time I launch a program or open a new tab in google chrome

    I had the same problem. I have exeprienced a random 1-2 dry freeze when I played games online (for example, League of Legends, Maple Story, etc.) or on my gaming laptop youtube videos. After countless trials and errors, the problem solved when I disabled the "NVIDIA device Audio (Extensible Wave) (WDM)"audio driver in Device Manager. The man was this frustrating...

  • Very bad audio and video performance

    I have a Pavilion dm1 laptop running Windows 7.  When I got all first the machine audio and video performance was very good.  However, towards the end of last year the performance for audio and video has become extremely slow.  Still, the sound stutters even without video.

    I used the tools to clean the registry, updated (or verified) all drivers I can think, but nothing has not improved.

    Maybe related, but less to worry about because it is necessary that in rare occasions, boot has become very slow too.

    I think I have tracked down a part of the problem by chance.

    Normally, I start my DM1 when connected to various devices of office as keyboards etc.  These are all plugged into the USB ports.  As the boot begins there very long delays in the process.  And when the boot ends stuttering audio and video as described.  However, if no USB device is attached during the boot process, start happening quickly and the audio/video all work fine.

    2. definition update for Windows Defender - KB915597 (definition 1.69.301.0)

    Other things, that he did...

    3. I have a Microsoft Lifecam VX-5000, and installed the software for it because I changed the USB port
    4. I had several errors with my Microsoft Wireless Multimedia Keyboard 1.1 and mouse.  I had to disable these updates last week, because they never properly install and keep trying to reinstall on each reboot:

    5. Microsoft - Input - Microsoft USB double receiver wireless keyboard IntelliType Pro)
    6. Microsoft - Input - Microsoft wireless receiver double USB mouse (IntelliPoint)

    Cripes, I bought Microsoft Products assuming that they would work well with Windows, and BOY was I wrong!  I got that grief of this keyboard, here and on XP prior agreement.

  • 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.

  • Fusion audio and video clip

    Will be the first evidence of fusion audio and video clips so that I can then change them as a clip?


    So that we keep in sync, I just wanted to clarify something... it is, your question is not out of sync audio before or after export. Ask not how to synchronize audio in Premiere Elements. Using the tools of Premiere Elements, you have been able to successfully replace the sound of the iPad with another audio source and synchronize the new audio source to component video without much trouble with Premiere Elements. I think that is correct based on what you wrote

    I found that I can synchronize the two audios and then delete one of the iPad and then link other audio and video. It seems that I can then edit the video and keep the linked video and audio.

    What did you use as your tools of Premiere Elements for the audio synchronization - Alt and arrow key (left or right) faucet to shift the audio 1 frame left or right or the SHIFT + ALT and arrow (left or right) tap to push 5 audio images left or right? These are details of Windows... for your Mac, did you use Option Alt and shift + Option for Shift + Alt? I'm strictly a Windows of the elements user.

    I hope that your future posts will clarify the following to make sure that we are clear about what your goals and make sure you have the information you need to work on your project.

    Is there a reason why you couldn't do all in a project and an export - create your Timeline with iPad video and audio special for it but also make additions to the project timeline prior to export of this timeline to a final product of Premiere Elements?

    If everything goes well and there is no problem that you have not mentioned, I would try to avoid re-encoding involved in the export and import of export in another project where the only issue is another exporting.

    Please consider.

    Looking forward to hear your progress as your schedule allows.
