Hello,
When I add any video or picture file before and after I place it in the timeline video track 1, it displays the top half screen right side up and the bottom half is upside down and reversed without applying any effects or transitions. It started doing this right after upgrading my windows 7 to windows 10. I'm not in 360 ( normal view ) I have uninstalled and reinstalled several times to no avail. I have been trying to figure this out for 3 days and I'm starting to run out of ideas. Also, I can export my project in any file format and it works just fine.
