Comment (by nickg):

 How to generate multiple versions of the same video file at different
 bitrates that are properly key-frame aligned? Is it posible with ffmpeg?

 Here is an article with example
 http://www.wowza.com/forums/content.php?192-Encoding-Suggestions-for-
 Video-on-Demand

 The article says that "Multi-birate encoding has not worked using ffmpeg"
 is it right?
