Video and Audio Are Out-Of-Sync After Recording With Camtasia on Windows

Problem

After finishing a recording, the video and audio seem to be out-of-sync.

Solution

This can be caused by a system resource issue. The computer processor or hardware cannot process both video and audio fast enough to keep them in-sync. There are various options to solve this solution. Please try all of the troubleshooting steps below.

Option 1: Update to the Latest Drivers

Check for updates for the hardware drivers on your computer. Visit your computer manufacturer's support site and check for updates based on your computer model number.

Windows Update searches for driver updates automatically. You can often find more recent ones manually.

Here are some popular manufacturer's support sites:

Option 2: Reduce Screen/Capture Frame Rate

Reducing the screen area and capture frame rate can free up more resources in order for the audio to be in-sync while capturing. For more information on system performance, see this article.

Option 3: Check Windows Recording and Playback Settings

Windows 10

Some Windows 10 devices enable audio enhancements. This can cause audio issues in your recording.

  1. In the Control Panel, select Sound > Recording tab.
  2. Select your recording device and click Properties.
  3. On the Advanced tab, deselect Enable audio enhancements and click Apply.

Try a new recording in Snagit to confirm that the audio issues are resolved.

Windows 10, Windows 8, or Windows 7

Snagit works best when the audio devices on the computer are configured to a 16-bit, 44.1 kHz sample rate. Check the sample rate on your computer and change it if necessary.

  1. In the Control Panel, select Sound > Recording (for microphone audio) or Playback (for system audio).
  2. Select the recording/playback device and click Properties.
  3. On the Advanced tab, set the Default Format to 16 bit, 44100 Hz (CD Quality).

  5. Close and reopen Camtasia. See if audio and video are in-sync during playback.

Option 5: Update Webcam

We have also seen this happen with webcams. Update the webcam to the latest driver available from the hardware manufacture's website.

Tip: Record the screen and audio

If you are recording the webcam and audio without recording the screen, try recording the screen as well. Once the recording has finished the screen video can be deleted from the timeline.

Option 6: Set Power to High Performance

  1. Press Windows+R on your keyboard to open the Run window.
  2. Type the following and click OK: control panel
  3. Select Hardware and Sound > Power Options.
  4. Select High Performance.
