Audio and Video do not sync once published

  • Updated 4 years ago
The video/audio sync is perfect in the project's timeline. Once I publish it to YouTube or MP4, it is about 2-3 seconds off. I have tried restarting, renaming the project, and publishing from a different machine. The sync is fine in AVI so I uploaded that to YouTube. I'm on 7.1.1

One other thing to mention, I get this message every time I publish a project to YouTube. I do not have any of these features in my video. I have been had lots of publishing issues since this error first appeared so I feel like they must be connected.

Your video contains at least one feature not supported by the YouTube plug-in.

If you continue producing, you may experience one or more of the following:
-Quiz or Survey will not be included in the video.
-Hotspots will not be included in the video.
-Side-by-side PIP is replaced by PIP on top of the video.
-TOC based on Markers cannot be included in the video.

To produce your video and upload to YouTube, choose OK.

To select a different production setting, choose Cancel.

Sorry to hear that you're having problems. The sync issue for MP4 or YouTube (which also uses MP4) is not a known problem. The best way for us to help you is for you to open a ticket at http://support.techsmith.com. Someone from our TechSupport staff will followup with you by email to help troubleshoot the issue you're seeing.

The message you reference is an informational message, and is unrelated to the sync problem. The message is simply there to tell you that there's something on your timeline that isn't supported by the Share to YouTube output. For example, if there are markers on your timeline, and you use the Share to YouTube option, you'll see this message to let you know that the resulting video won't have a Table of Contents (TOC).

Hope this helps.

I just searched for this exact issue and found this posting I made months ago. I forgot I already had this problem!! I wanted to share my workaround for anyone that happens on this topic. (Or in case I can't remember 6 months from now.) I exported the screen action and audio to separate files. Created a new project and imported those files in and then produced. The YouTube window is now totally in sync. :)

Thanks for posting and have a great day/night. I would also suggest trying the free trial of Camtasia Studio 8 as some issues were taken care of in the newest version. Just a suggestion.

In my case, I can get a separate audio and video track to sync perfectly. But then on export (Produce and Share), the audio is not synced by 1-2 seconds.

I'm running 8.02 on Windows 7 64-bit. I've tried most of the export types including the custom option to manually set the frame rate at 30 seconds. Also tried different media players with same out of sync results.

Is there anything in Camtasia or the timeline that would cause the audio to go out of sync with the video when using the Produce and Share feature?

Hey, bartlettcharles. This issue sounds exactly like what I ran into in 7.1. The workaround I posted above worked for me. I'm sorry to hear this issue still exists in version 8.

Thanks for the reply. Actually, my starting point is your workaround (separate video and audio files). So maybe the problem is worse in 8.02.

For a second I thought it might have been caused by shooting video in AVCHD, but checked the camera and I'm definitely importing an mp4 file. Thanks again.

have done a lot of camtasia recordings and edits over the years. I noticed that apple prores files have an out-of-sync issue which grows with the video length. This may happen with different cameras and sources.

Looks like camtasia does not like FPS of 29.97 fps or 23.98 fps. Looks like it rounds up to 30 fps and 24 fps respectively.

Solution: Run the video through http://www.macroplant.com/adapter/ (it is free) to change the frame-rate. This will fix the issue. ( For AVCHD I run them through iMovie first and export as quicktime)

**For sync up multiple camera angles, I'd suggest trying out PluralEyes (http://pluraleyes.com).And if you're just shooting on 1 camera, check out DreamSync (http://dreamsyncapp.com). It's not as cumbersome or expensive as PluralEyes and gets the job done for smaller quick projects. 

**There's acutally an app called DreamSync, a standalone application that's built for the novice user as well as professionals. It syncs your footage and audio into one single clip so that it can then be imported into applications like iMovie, Windows Movie Maker, Adobe Premiere, Final Cut X, or any other editing suite.

Both apps are effective depending on your editing workflow and how much (or little) time you want to dedicate to learning another interface for syncing audio/video footage.
