Final Production - missing / garbled audio

  • Updated 1 year ago
I've been using Camtasia to create some animated videos with underlying music and I've had no issues with playing the production in the tool but when I export it to an MP4 - there are certain parts of the music that just drop to silence or garble.  

Any idea what could be causing this and how I can fix?  Did the production file somehow get corrupted?

I am assuming that you have tried the export more than once?  
When you click share and the production wizard starts what production method are you choosing?
What settings are you using for audio?

Is your audio at "normal" levels within Camtasia?

This is actually not that uncommon if your using VBR music files "Variable Bit Rate" Camtasia just doesn't digest that type of file well for some reason.

Camtasia has always worked well with 44,100 16 bit audio using the .wav format.
The best thing to do is convert your audio to that format.

The easiest way to that is let Camtasia do it for you.

You can covert multiple tracks all at the same time. However, that lumps all the audio into one master track. If there's overlapping audio the way the original tracks were stacked, you've lost the ability to edit volume levels and that content separately.So unless your absolutely sure your done editing, you should export your audio tracks separately.I highly recommend exporting all tracks separately.    

To do that, lock all but one audio track and export to .wav one by one.
 

 Right click the track you just exported and select update media.


Select the file Camtasia just created and select open.The file will be replaced and placed in the media bin.
It will have been converted to 44,100 16 bit .wav here is that same file in Adobe's Audition.
