Snagit (Mac): Audio plays back in Snagit, but not when shared


A mp4 video that is recorded using Snagit, plays back audio when viewed in Snagit. However when the mp4 is uploaded directly from the Autosaved Captures (to something like, or Youtube), there is no audio (or some of it is missing).


Note: This does not apply to Snagit on Mac 4.X and later. If you are experiencing similar problems with version 4.X, please submit a support ticket with us.

Snagit on Mac has the ability to record both system audio and microphone audio at the same time.  This will record the two audio streams as two separate tracks within the mp4 file that is created.  However, these two streams cannot be merged until the video is manually saved or shared using an output in Snagit.  

  1. Open the video in Snagit.
  2. Browse to the menu bar item File > Save as, and save the video as a mp4.

  3. Upload this mp4 (instead of the one in the Autosaved Captures folder).


  1. Open the video in Snagit.
  2. Use one of the Share outputs available in Snagit to upload the video to your desired destination.
