Inverted thunbnails

[earthshaker]

I have found that the videos shot while the camera is mounted upside down, in the car have less movement or shaking. It is easy enough to invert them back to top side up, in the time line, but is there a way to invert the thumbnails back to the correct orientation?

I don't know if there is a way to invert the thumbnails direct since they are taken from the original video. One way of correcting the problem might be apply the "inversion" effect to the whole video and render it to a new video file. Then use the new video and the thumbnails should be correct
