This gist shows how to extract motion from a video using the method described by Posy in https://www.youtube.com/watch?v=NSS6yAMZF78
To get the motion from a video by comparing each frame to the one 5 frames later:
./motionextractor.sh input.mp4 5 output.mp4To compare to the first frame:

| # Extract frames from video every X seconds and geotag them using GPS data file. | |
| # Requires exiftool and ffmpeg. |

| # bash 1 bit image viewer | |
| # Usage: ./readbinary.sh filename linelength | |
| # Try echo '\x07\xe0\x1c\x38\x32\x4c\x30\x0c\x33\xcc\x18\x18\x07\xe0' > onebitimage; ./readbinary.sh onebitimage 16 | |
| # `xxd -b` gets binary dump of file, | |
| # first `awk` matches part after line number, | |
| # second `awk` strips ascii interpretation, | |
| # `tr` strips space, period, linebreak | |
