It has nothing to do with the length of the clip and the mix should be the most important part.
The aim is to show your site has enough porn that's worth signing up for and good and unique enough to make the viewer think he should come and look at the site. You have to hit the surfer in the first 10 seconds that your content is good and make him look at it, not see it, and start to get involved. Then hit him with a few 10 second hits of the hi lites. Then at the end give him a bloody good reason to come over and see what you have on your tour.
Then upload more of the same to the same site. In case he searches for more of your work.
Think in terms of movie premiers. Little snippets to build the desire to come back next week and buy a ticket.
OK I know what to do but don't do it and am clueless.
