Camtasia (Mac): Zero Byte File Exported


When exporting a project from Camtasia for Mac 2 or 3 in a specific manner the resulting file shows in Finder as 0 KB:

Camtasia 2: Share > Advanced Export > Export to MP4 (not Export to Main Concept .mp4)

Camtasia 3: Share > Local File...>Export to MP4 (not Export to Main Concept .mp4)   


There are two reasons this behavior can occur.   

Cause 1

In the Advanced Export Options you are choosing a Custom Audio Data Rate and choosing something below 30 kbits/sec or above 255 kbits/sec.

Solution 2

Change the video profile in the Advanced Export Options to any of the options with "AutoLevel":
