I made 37 videos that are intended to be merged into a Kickstarter video - but when I transfer them to my PC - guess what - they are all upside down. The thumbnail is right side up - why is the video upside down and how can I fix all these videos?
Anything Apple-related will show the items right side up. PC will show them either upside down or 90 degrees rotated (pix) unless you use a third-party program to turn them to the proper attitude and then save them again as such. Irfanview can do this for photos; not sure about video.
