Choose the 'use software-mode only' option and restart Camtasia, then try to make a test video and see if this fixed the issue. In order to do this go to Edit > Preferences > Advanced tab and select the Hardware acceleration feature. However, if the problem persists, you should try adjusting the settings, because it is quite possible that the equipment you have can't support the video or audio quality you selected. As the great Alexander Graham Bell once said 'Preparation is the key to success', so before starting your recording session make sure that you've checked everything twice.

There isn't anything more frustrating than realizing that your video and audio are out of sync once you've finished the recording session. After recording my video and audio are out of sync, how to fix it? We will provide quick solutions to these annoying problems that take the fun out of the screen capturing experience. Furthermore, some users have experienced audio and video syncing problems in Camtasia. More advanced users who want nothing but the crystal clear audio recordings in their videos will probably find Camtasia's audio recording features underwhelming.

Even though the software allows you to record audio files with external and internal audio recording devices the final audio outputs aren't always as good as one would expect from such a mighty screen recording and video editing tool. The Camtasia screen capture software is far from being ideal for recording audio files.
