video - command line editing:

• 
  MPEG [8Mb]

  using ffmpeg [from the command line] to decompose video into image folders - and then using bash script to compose two image folders into one video

• 
  MPEG [9Mb]

  using ffmpeg [from the command line] to decompose video into image folders - and then using bash script to compose two image folders into one video





using ffmpeg:

ffmpeg -y -i filename.dv -s cif -qmin 20 ./img1/img%04d.png

*after executing the bash/python script below...
[which takes a # of images from each folder and moves them in sequence to the /cmp folder]

ffmpeg -y -i cmp/img%04d.png -b 2000 output_filename.mpeg




*the python script in the box below is piped through bash:

python filename | bash
