Each folder contains cropped 4000x4500 8 bit per plane PNGs for the scene "XX.YY".
The frames have both the left and the right eye, left on the top, right on the bottom.
The file "list.txt" is the list of all frames used in the movie, in sequential 
order as they are to appear in the final movie if they are to match the soundtrack.

Example commandline for encoding a monoscopic 30 fps 1080p version of the movie with
MPlayer's mencoder and x264:

mencoder mf://@list.txt -mf w=4000:h=4500:fps=60:type=png -ovc x264 \
    -x264encopts profile=high:level=4.1:preset=placebo:tune=animation:ref=4:bitrate=3000 \
    -vf scale=1920:-2,stereo3d=abl:ml,scale -fps 60 -ofps 30 -o bbb_1080p_30fps_normal.avi

Some of the folders contain more frames than are strictly needed to create the movie.
