# MEncoder nonsense

# MJPEG video input, and I stupidly rotated the camera while taking the movie.
# Not sure how to make transcode do JPEG decoding without amplifying noise.
# Thus: MEncoder

# Need forceidx because mjpeg isn't seekable in the typical fashion
# Clip off 4.4 seconds from beginning, then rotate it 90 degrees CCW and expand
#     it to 640x640 (to account for rotation).
