Less choices is right. Loads of research to show that.
However, sending them straight to one payment page, with one choice won't work as well as giving them, say, three choices.
1) One month recurring @ £18.78
2) 3/6 month recurring @ £14.96 per month
3) 2 day trial @ £1
Prices are just made up, but shows you the jist.
You need a page to sell to them, before they hit the payment page. I am sure of that. Look at ANY big site. They all do it, and they all will have tested the idea with a lot more data than you have available.

And there is one trailer, yes, but when you click on any of the updates, it takes me to a page that has a non clickable graphic over the player inviting me to join, but obviously, it isn't clickable! Show them more!
You can't decide to join a site based on a still from a video and no sales text, imho!
