Error -2002: a bad public movie atom was found in the movie
I am trying to convert .mov files to avi or mpeg-4 files to edit in windows to create a video. The source is a mov file from a Nikon Coolpix camera. It is a model L-11. When I open the file in quick time it plays fine, but when I go to export the file to create a mpeg-4 file it starts the process the export progress bar opens and it sits at 0% for a little then it fails and shows the error "Error -2002: a bad public movie atom was found in the movie" I have tried changing the settings a number of times but no improvement. The issue is affecting some mov files i have and some it failed. No idea of what the issue is and if I have to just shoot a lot of stuff and hope that about half of them can be converted. Any ideas on what causes it would help. Could not find any referance to what bad public atom is so no idea what to look at. Did an web search and a search of this group and could find no solution that seemed to fit.
