Have a problem using the GoPro Omni Importer? Have you encountered a bug that needs fixing? Please post it here. Des difficultés à utiliser le GoPro Omni Importer ? Avez-vous découvert un bug qui doit être fixé ? Postez les ici.
I'll try to reproduce your issue but just to make things clearer for me : -> All your SD cards are coming straight out of Omni? -> Your OS is Windows 10? -> Have you the permissions to write in the directory where you're trying to import your footages? (this might be your issue).
