question concerning bk2 encoding

[Kitsune1982]

hey guys. Was looking at some different file types from 2 different games and noticed XCOM2 has bk2 videos and games like syberia and the witcher have .bik videos. i know how to encode bik, but could someone tell me if there is a tool or a legal free method to encode bk2 to/from the usual video formats - avi, mp4, mov, mkv etc as in, bk2 to mp4, mp4 to bk2 etc - i know rad tools can convert bik movies but is there a way to convert and edit bk2 video files without having to pay 5000 bucks for a bink 2 sdk? i know some of you out there have successfully encoded bk2 movies for games like WWF Smackdown and so on.
please post back, i would like to know how to convert a .BK2 to a different format, edit it then reconvert because as far as i know, encoding a bk2 with the bink 1 encoder then renaming the output file extension to .bk2 will cause the game that uses bink 2 videos to crash when reinserted back into the game.

thanks, catch you on the flip side.
