On C4S I sell my shorter clips (four or five minutes long) which are sub-parts of my full length scenes (usually 25-45 min.) for the standard C4S pricing, eg 5 minutes for $5.99. And I sell the full length sex scenes for the higher prices of approx. $1 per minute, say $24.95 or $29.95, unless they are really long videos of 45-50 minutes in length, in which case I bring them back down to a maximum of about $29.95 or so. There are a couple of full length specialty videos that I sell for as much as $39.95 however and get regular sales for those too.
Clips.com standard pricing is a little less, and I follow suit with their recommendations- shorter sub-clips are just a few dollars ($3-$5 or so) and the longer full length videos I make top out at lower pricing than C4S, let's say $10-$15 for a full length 35 minute video. I sell less videos on Clips.com than C4S, but Clips.com have caught up a bit recently. Of course a lower default pricing than C4S plus a 60% commission for the site rather than C4S 40% means my net is much lower.
ClipClinic.com I have not managed to sell one single clip yet from the small selection I have uploaded, despite having my store featured for over a month. The interface there is maddeningly complex and it's simply too difficult and time consuming to continue to upload clips there. It takes as many as 20 steps and at least eight separate screens to add a new clip to a store unlike C4S and Clips.com's pretty usable interfaces, so I am not likely to keep uploading more clips unless I hire some broke webmaster or third world grunt worker to do the mind numbing work required to add more clips to my ClipClinic stores. It seems to me that the ClipClinic traffic is more fetish and amateur based anyway, so maybe my stores are not a great match for the customer base there. And like Clips.com you are looking at giving up 60% for the privilege of selling clips there.
All these third party clips stores are decent extra money if you know how to work them including sending your own traffic to the stores which is key now that the C4S main page is divided up into niches and overwhelmed with new studios. I will continue to offer my clips on all these platforms and others that may pop up. But I recently decided to exercise more control over my clip sales and traffic. Tired of giving up 40%-60% to the other platforms, I decided to create my own downloadable clip store at
http://JimGunn.com that I can send my own traffic to. The site uses a heavily modified version of Wordpress (free) as the CMS, and uses my own billing and an inexpensive token based downloadable video-on-demand script.
Instead of a per minute pricing, I went with a flat pricing per scene of $5 or $10 per full length videos rather than cutting up the videos into short clips. It's nice to have customers purchase as much as $50 of tokens at a time and keep more than 95% of that money. It is also nice to have 100% control of my site design and overall presentation so that I can show trailers, scene descriptions, scene ratings, related scenes, niche tags and other interactive elements, and also keep 100% control of my own traffic and be able to collect customer information including sales data and email addresses. I think that the market for downloadable clips will continue to grow.
