Video upside down when transfer to pc

[JeremyH]

Using v15.0.3 Professional on iPhone4 mounted in an Optrix holder suspended below rollcage - so camera lens is at bottom edge of iPhone when mounted.
Got a great video of racing at Brands Hatch last weekend and lap overlays are going on fine (not finished all yet).
I want to upload raw video to YouTube, so I MOVE it to camera roll OK, then copy it to laptop OK.
BUT it's upside down!!

Can I invert it on laptop or is there a transfer step I've missed or messed?

this is down to the camera, windows live movie maker (free) can rotate it for you.
