Camtasia (Windows): Error 2002: a Bad Public Movie Atom Was Found in the Movie

Problem

Error -2002: a bad public movie atom was found in the movie (.mp4)

Solution

We have seen odd frame rates of source files cause this error message after production. When producing the MP4, do the following:

  1. Select File > Produce and Share > Custom Production Settings > MP4 > Video Settings.
  2. Change frame rate from Automatic to 30.

We also seen producing to a network drive or folder that syncs with cloud storage because of this behavior. We recommend all source files and production folder be on the local hard drive.
