How to rotate videos?

[klumy]

Is there a chance to rotate videos to 90°?

Yes, via Avisynth.

If it's an avi save the following two lines as a file with extension .avs into the same directory as your video*:

Avisource("Name of your video")
TurnRight()

(or TurnLeft)
If it's no avi replace AviSource with DirectShowSource, in that case it may also be necessary to add the framerate like this: DirectShowSource("blah.wmv",fps=25).

Then go to the Winamp preferences > Input > Nullsoft DirectShow decoder > Configure and add ;AVS to the extension list, now you can play the avs script in Winamp like any video.

*you can also save it anywhere, then you have to put the full path to your video between the quotation marks
