+'''
+This program takes one or more video files as input and outputs timeline images.
+If a cuts path is given, it also outputs a json file containing cuts. If in and
+out points are given, only that part of the video(s) will be rendered.
+
+The timeline modes can be any combination of 'antialias' (average color),
+'slitscan' (center pixel), 'keyframes' (one or more frames per cut), 'audio'
+(waveform), 'cuts' (antialias with cut detection overlay, for debugging) and
+'data' (each frame resized to 8x8 px).
+
+One or two timeline heights can be specified, larger height first. The timeline
+widths will be 1 px per frame for the first one, and 1 px per second for the
+second (smaller) one. If the wide option is set, large 'keyframeswide' tiles
+will be rendered. They can be used at a later point to render small 'keyframes'
+tiles without having to decode the video again.
