Hello fenderman,
Just so I'm clear, are you referring to the "Settings/Clips and Archiving" section where you configure export?
The checkbox called "Add the camera's current text and graphic overly" seems to be the only one that makes sense. However, if I check that box and hit ok, it comes back saying "Files will be overwritten--are you sure?" Just not sure which files it wants to overwrite, so better safe than sorry.
Any info you can share would be appreciated!
