Why is my video audio out of sync for video files uploaded to Dropbox?

I have .mov file I created in which the audio sync is correct on my computer (Mac). But when I upload the .mov file to my DropBox account, the audio is out of sync in the copy on DropBox.

How do I fix this?

Thank you!

  • I figured it out.  The file on DropBox is fine: when I DOWNLOAD it, there are no sync issues. So it looks as though the problem is opening it from DropBox. The playback Codecs playing from the Web site mess up the sync. But as long as the file is fine, my co-collaborators will be able to download it.

     

    Thanks for taking the time to reply.

      Thanks for writing back, criehl
       
      Hmm. :thinking: Out of curiosity, do you experience this in all browsers available on your device, as well as incognito mode? Could you also ensure that you’re not running any browser extensions or plug-ins that could be hindering the process?
       
      Let me know what you find!

        I am having this same issue when uploading to dropbox from the website. When trying to post on Instagram the video and audio is out of sync.

    Hi there criehl, could you please elaborate a bit on this so as to have a better understanding? For example:
    • How did you add the video to your Dropbox folder? From the website or the desktop app?
    • Are you previewing this on the website or using your Dropbox folder on your desktop?
    • Are you having this issue with only that video or others too?
    • If you added and/or are previewing the video through the Dropbox folder, could you please let me know what the Dropbox icon that’s next to your computer’s clock reads when you click it?
    Thank you in advance!

    I can't believe how Dropbox is bad currently, I'm using it for years for my business and now I can't anymore.

    I'm a video editor and I'm sending videos to my clients all the time, and they keep asking for revisions just because videos are out of sync on Dropbox preview, and they last longer with black screen on the end without a reason.

    There are no any problems with my files when I'm using a player to see them on my computer.

    Does anyone have same problem?

      Hi AlonerCRO; welcome to our Community!

      As your query seems to echo this discussion here, I moved your post under this thread to keep things neat around our Community.

      Can you let me know if any of my previous suggestions (clearing your browser's cache, trying an incognito window or another browser) improve this at all?

      If not, may I reach out via your Dropbox associated email address to have a further look internally?

    Hi there fellow dropbox users, 

     

    I don't remember this happening to me in the past and I have been using the same set-up for months but the problem has been happening for the last two weeks so I'm kinda lost. 

     

    I use a Samsung S7, a MacBook Pro 16" 2019 with Catalina and I have the dropbox app on both. Basically I upload videos from my computer onto my Dropbox and then I export the video and save it to my device on my phone so I can upload that said video on Instagram. The problem is that every time I do it now, the audio of the file that's been saved on my device is out of sync... 

     

    Anyone knows what to do?
