Camtasia (Windows): Production Hangs/Freezes with Imported WMV File or Shows Blank Thumbnail in Clip Bin


Production hangs/freezes with imported WMV files from webinar applications.


WMV files made in any webiner software may exhibit one or more of the following errors:

  • The thumbnails in the Clip Bin or Timeline are blank.
  • Attempting to produce a project with a certain clip hangs.
  • The audio/video can be out-of-sync in the Timeline.

The Microsoft Screen Capture codec does not contain time stamps. These are needed for Camtasia to edit and produce a movie. This essentially puts gaps in the file that Camtasia cannot read. The lack of time stamps in these WMV files are also an issue in Microsoft’s Movie Maker and Producer. The best workaround is follow one of these methods below:

The best workaround is to use Camtasia Recorder to capture the playback of the WMV file from another program, and use this new .camrec or AVI in a new project. This will ensure you have a recording that can be properly rendered in Camtasia Studio 8.
