simple-deinterlacer is a simple bash script that will deinterlace any video file using ffmpeg.
You will need to have bash and ffmpeg installed on your system for this to work.
Simply run the script with a video file together like this:
$ ./script.sh example.vob
The script will then ask you which field order you would like to deinterlace the video with, you can check the field order of the video with a program like mediainfo-gui, but there is also a built-in auto detection option in the script.
