If the point is to send it to sponsors, you should cut it down to no more than a minute. I don't have any experience with MMA/jiu jitsu sponsors but I do with music sponsorships. You've got less than 30 seconds to spark their interest and then try to hold it for another 30. If you don't have them in that first 30 seconds they're just going to skip right past it. Think TV commercial -- you're trying to sell yourself as a walking ad campaign after all. Six minutes is an eternity for a promo pack. The first time I watched it, I watched it with the mindset of a sponsor and you lost me in the first match. It's got nothing to do with your jitz and everything to do with short-attention-span-theater. You've got some great material in there it just needs editing. I agree about the music transition right now, but that should be irrelevant in the end product. You won't have more than a minute of music anyway. Find a friend that couldn't care less about jiu jitsu and have them help you with the editing. They'll help you edit out the stuff *you* think is awesome but is meaningless to someone with no background. If you can sell him or her, you can sell a sponsor.
