a mainstream movie trailer is the length is it for several reasons that have nothing to do with showing the audience what they are going to see.

First off, when a big budget movie is announced, the average trailer is 90 seconds for the first several weeks, then shortened to 45 seconds (obviously this varies). This is not because they only want you to see that much! It's because it costs $105,000 to show a 90 second trailer once on a network during prime time. That 45 second trailer, still costs $52,500 to air once!

Porn producers don't pay $100,000 to show their trailer once! I've seen trailers for big movies 10 times during prime time in 1 night, that's $1M they spent that night, just on the channels I was watching.

now, take away the cost, and assume that they could show their trailers for free, would they do the same? NO, their trailers would be exactly 2 minutes and 30 seconds every time, why? Because it is mandated by the Motion Picture Association of America, they aren't allowed to make them any longer.
