I did a second one that has much improved audio over the first one.   I have a better audio editor now and I'm able to mix, plus added sound effects and dialouge to spice it up.   Also used a different audio codec that doesn't squash the audio as much.   The video is more tightly edited and more 'trailer-like', plus it's shorter.

Here's a Grievous 'trailer' I did using the xbox & workprint footage.   It has probably 95% of all the Grievous scenes in it.   The audio is mainly the 'Grievous theme', I would have put more sound effects & dialouge in if I had a better audio editor, as it is it's mostly pieced together bits.   And I use the term 'trailer' lightly, as it's a lot longer (and with extended sequences) than a standard trailer .
