Um.... so where's the tutorial? Can't seem to find it. "You need mencoder and mpeg4 codec." More information please.
So in the mencoder man file, near the very end, they list some examples... one of which is: To encode all *.jpg files in the current directory: mencoder "mf://*.jpg" -mf fps=25 -o output.avi -ovc lavc -lavcopts vcodec=mpeg4 This seems to do the trick!
