I have a bunch of videos filmed on a camera that was mounted sideways and would like to rotate them.
I have been using the command,
mencoder -vf rotate=1 -ovc lavc -oac copy <Original>.avi -o <copied>.avi
which works fine, but the files are then about 1/5th the size of the original. There is a noticeable loss in quality of the video being much more pixelated and grainy.
Any suggestions for programs to do the job properly...or am I doing something wrong.
