1000 - 520 = 480 and so on.
Except for simple FadeOut and Trim commands, the intro video was relatively straightforward. The show video itself had some extras, including a subtitle call for adding the Indian voices to the credits. The file was as below:
++ subtitle(Trim(mix,39024,40504), "Indian voices: K, A, V", -1, 1000, align=2, 651, 699)
++ FadeOut(Trim(mix,3116, 37816),60)
The last line being actually on a single line with all the ++ etc. The outro also had some gymnastics because of an extra line of audio I wanted added. This was before the Virtualdub quadrilateral transformation:
video_pre ++ video
Finally, all the three - intro, outro and the show itself - were put in a KMPlayer playlist, a .KPL file.
