The Invideous in-player Paywall does exactly that. We integrate directly with mainstream OVPs at platform level meaning you can usually add the Paywall via your OVP control panel, so no complicated setup or API knowledge required. The Invideous Paywall then enables you as a Publisher to process consumer payments within your video player without viewers leaving the page.
You set the initial 'free' period, I.e.60 seconds. The Paywall then stops the video and processes the user payment via C/Card, D/Card, Paypal or SMS at the rate you have specified, before allowing playback to resume.
Tariff options are set using the web based control panel, options include single view, daily/weekly/monthly access or rolling subscriptions. The Paywall supports 12 languages and handles most major currencies. Receipts are fully branded and the look and feel of the paywall itself can be configured in line with your site.
Although rarely needed, 24hr consumer support services are in place for peace of mind. You can also us the voucher based system to offer consumer discounts by email to assist in marketing etc...
There are no set-up fees and Invideous simply retain a small fraction of ongoing revenues.
Please drop me a line if you are interested in trialling, I'd be happy to talk you through it.
