During playback the audio ends at the right spot- but upon publishing, and playing the Quicktime >mov- The audio loops at the end, and starts playing again
We will be releasing a new patch version of VideoScribe soon that will address some of these issues so you might want to wait a while for that.
If you go back to 1.3.26 you will not be able to open any scribes created with version 2.
...or, if you can't do that, add a soundtrack that's longer the voiceover will not loop. If you don't want to listen to the music just set it to zero volume.
