Audio and Video Are Out of Sync After Recording With Camtasia on macOS


When finished recording from a web cam, the audio and video is out of sync, pixelated, or has a low frame rate.


This is a known issue that we hope to improve on in future releases. Please try all of the troubleshooting steps below.

Camtasia 2020 and Later

This should be fixed in Camtasia 2022. If you are using Camtasia 2020 and experiencing this issue, please check the Camtasia Recorder webcam portion is set to 1920x1080 or lower. This can be found in the Camtasia Recorder before starting the recording.

Camtasia 2019 and Earlier

These versions can only record a web cam at a maximum resolution of 1280x720. If higher resolution is needed, upgrade to Camtasia 2020 or later, or use QuickTime (or another program) to record the webcam.

Other possible solutions (Any Version)

Option 1: Restart computer with the webcam plugged in.

Option 2: Make sure there are no unnecessary programs running when attempting to record (this will free up resources).

Option 3: Try the built-in webcam to see if issues occur with this webcam.

Option 4: Record with Quicktime and see if the same behavior is happening with the same webcams.

Option 5: Set sample rate of the audio file to 11025 Hz, 22050 Hz, or 44100 Hz.

Camtasia (Mac) is compatible with numerous audio sampling rates. However, some sampling rates such as 48000 Hz or 96000 Hz may not work properly and result in noisy or distorted audio. This problem occurs with Camtasia recordings and imported media containing audio.

Application programs on macOS can set the sampling rate and change it to an uneven rate. macOS has a program called Audio MIDI Setup installed on Mac. Follow instructions to reset sampling rates.

    1. Open a new Finder window.
    2. Select Applications > Utilities.
    3. Double click Audio MIDI Setup.
    4. Set the Input and Output Format Rate to 44.1 Hz.

Option 6: Disable Automatic Graphics Switching.

  • Open the macOS System Preferences and then open Energy Saver
  • Click the lock to make changes and enter the computer password.
  • If you see Automatic Graphics Switching, make sure it is unchecked. If it was checked please unchecked this and restart the computer.
    • If it wasn’t checked, check it, restart the computer, go back to the setting and uncheck it and restart the computer one more time

      Not all computers have this option. If this is not an option on your computer please skip these steps.

  • Try recording a new video with Camtasia.
