Does not fix upside down videos

My recorded videos play upside down on my PC. They play right side up on my iPhone. I tried rotating my video with this app so it plays upside down in my phone. I saved it to my photos on the phone, and yes, it plays upside down on my phone. I copy it off to the computer, and it still plays upside down on my PC. I just wanted to add, I tried both export options, fast and slow. Neither worked.
