Rotate a .3gp video file taken by phone

[ArisVer]

Is there a way I can rotate this video using a free program?

I have managed to rotate it using Windows Movie Maker. Anyone knows whether it sacrifices quality?

Anything that re-encodes the video (to a non lossless format) is going to potentially sacrifice the quality.

FFMpeg does a great job with it, and there is a gui for it that offers a ton of options (including rotating the video) with a program called WinFF: http://winff.org/html_new/

You could also use handbrake.

You loose some quality, yes

*.3gp and worried about quality. The loss can be minimized.

I have tried FFMpeg and didn't do it. It actually rotated the video 180 degrees in one of the tests. And I don't see any rotate options in Handbrake (10.2.286).

I ended up saving the original file alongside the converted one, just in case.
