.bik

I want to work on making introduction videos for custom maps (the Watch Movie button when viewing the map's objectives when you connect to it), but I noticed the file format for said introduction videos is Bink Video, or .bik. However, while RAD Game Tools has a download for their Bink...

valve made for their own videos for their maps and their also have lyrics when you watch them in game. i made my own video for my map: View: https://www.youtube.com/watch?v=DLzTDsdllH4 but i don't know how to make lyrics for it. anyone knows? or knows a tutorial for that?
