When editing a video in Premiere Elements the sound will not sync.

[Carl5E46]

If users try to edit a video in Adobe Elements, the sound will not be synced. The file is an mp4 files.

When users try to trim the video using Elements, the sound gets out of sync by about 2 or 3 seconds.
They can manually adjust the audio but it's not ideal and it takes time to try and line it up perfectly and with the amount of videos they edit, that solution is not ideal.

We have tried using a Handbrake to force a constant frame rate but this did not help. We have also verified our systems are powerful enough to meet minimum requirements for the 2021 version of Adobe elements.

Any other suggestions that might help resolve this issue?

I have never had that issue.  Will you please share one of your clips so I can see if the issue duplicates in my laptop system.  Thanks in advance.   (For sharing, use DropBox, OneDrive, Google Drive or upload here.)

@Bill Sprague , is the you tube vidoe Caitlin posted sufficient for you to try and duplicate the issue on your laptop?

No.  What you put on YouTube is exported output.  It processed in your software and processed again in YouTube's software.  To try to duplicate and figure it out, one would need a clip from the source camera.

Hi Bill, please see the attached video below. I tried to upload it before but it wouldn't let me. I hope this time it works.

Thank you,

I downloaded your video.  No matter what I use to play it, the audio is out of sync.  That means you didn't send me an original camera clip so I can't try to figure out the fix.  Unlike a video editor, a simple video player like VLC or the Windows default should play it.   If it is straight from your camera, your cameras has a recording problem of some sort.   

Assuming that, instead of from your camera, it is exported output from Premiere Elements (or some other video editor) it can be fixed.    (1) Put the clip on a Premiere Elements timeline.  (2) Select the clip, right click and choose "Unlink Audio and Video".  (3) Select only the audio track.  (4) Hold down the Alt key an press the right arrow key a few times.   That "nudges" the timing of the audio track by the equivalent of a frame.    Depending on the severity of the sync timing, you might need a frame less or more.   On my computer, five frames seemed to work.   Attached is a portion of my output. 

(I would still like to try an original, straight from the camera clip!)

Hello, Please see the attached file for the non-edited video. The video is all good until we put it into the editor.

Sorry that I didn't see this sooner.   MediaInfo reports that your video uses the AVC1/H.264 codec and has a variable frame rate.   I'm not sure why, but it seems that variable frame rates might be used reduce file size mostly in phones.   Variable frame rate video always plays well in simple players but does not always work well in video editing software including Premiere Elements.   It is better now than it used to be. 

Your first post said you are using version 2021.  I have version 2024 installed and your test file didn't cause any trouble in a simple in and out project.   Attached is the output.  MediaInfo lists the output as using a constant frame rate.    

Over the last few years, the subject of variable frame rates has come up.  Whenever anyone has shared a "problem" file,  I've not had trouble using it.   It may be that a combination of software, CPU, RAM and graphics card are involved.   Or, it may be that somewhere in the last couple of updates, Premiere Elements has adapted.  

If you like Premiere Elements workflow style, you might consider the newest version.  Please use the free trial before you spend money!
