Camtasia (Windows): After recording my video and audio are out of sync

This is usually a system resource issue.  Your computer processor or hardware cannot process both the video and audio fast enough to keep them in sync. We can try a few things to correct this:

  • Camtasia 9 Software-Only Mode: Open Camtasia 9 and click Edit > Preferences > Advanced tab.  Under hardware acceleration change that drop down to "use software-mode only".  Then close and re-open Camtasia and see if your audio and video are now in sync during playback.
  • Reducing the screen area you are recording along with reducing the capture frame rate can help free up more resources in order to capture the audio in sync.  For more on system performance click here.
  • In some other cases we have seen outdated audio or video card driver cause this behavior.  It is best to visit the hardware manufacturer's website to get the latest drivers for your audio and video cards.
  • Another test to verify if it is a system resource issue is to see how many frames are being dropped during your recording.  In Camtasia Recorder click on Tools > Recording Toolbars and make sure Statistics is checked.  Once done perform a test capture.  During the recording on the recording toolbar you'll notice the following.

Look to see how many frames were dropped compared to the total amount captured.  A normal capture of screen content (e.g. recording a program, PowerPoint presentation) should be dropping very few frames (less than 10).  If you have a lot of dropped frames this will confirm it is a system resource issue.

Recording high motion content (e.g. video, games) will typically result in significant lost frames.
