Satya's blog - mencoder rotates video files
So I made a video with my cell phone camera held wrong, and to fix it I used this:
mencoder -o OUTFILE.dv \ -vf-add rotate=1 \ -vf-add scale=640:480 \ INFILE.dv \ -oac copy -ovc lavc
To keep aspect ratio and add black bars:
mencoder -o OUTFILE.dv \ -vf-add rotate=1 \ -vf-add scale=-10:480,expand=640:480 INFILE.dv \ -oac copy -ovc lavc(via http://lists.mplayerhq.hu/pipermail/mencoder-users/2006-February/002843.html)
Winff can convert 3gp files to raw DV, but it's a GUI application.
