2 .SH NAME
3 blind - Collection of command line video editing utilities
4 .SH DESCRIPTION
5 .B blind
6 is a collection of command line video editing utilities.
7 .B blind
8 uses a custom raw video format with a simple container.
9 If you have a video file you want to edit, you first
10 have to convert it with
11 .BR blind-from-video (1).
12 To be able to play your video in a video play, you
13 have to convert it with
14 .BR blind-to-video (1).
15 .P
16 Raw video takes up tremendous amount of space, you
17 should therefore avoid storing the video without
18 first convert it with
19 .BR blind-to-video (1).
