How to play .bk2 videos and re-encode them properly?

[darkwolves]

be careful using the radtools or bink encoder you need to know what you are doing or you could lose sound and the game can crash when a cutscene comes up.
another problem i've seen happen on the game DMC-Devil May cry for example the video was indeed reduced but alot of the sound like peoples voices were missing they were mute...if you do not know how to edit text files that go along with the video then i highly recommend against trying to re encode them...
if you do know how happy re encoding
