I just had one accepted on some big ll's I used two galleries 4 clips each gallery 16 seconds per clip to make sure it was at least 120 seconds (8 x 16 secs total 128). More clips, more the user has to go back to your gallery page or stay on it. I also didn't want the visitor managing to have a wank frenzy with a 30 second clip and not be in any state to visit a sponsor!!
