IMHO the stock video marketplaces need to add the ability for content creators to showcase their work across social media networks and other distribution channels with the least amount of friction possible. The reason why this is valuable is because I want to share out and talk about my storytelling as a real tool for viral video makers to invest in high quality content and be able to send them directly to a buy now page to capture the impulse buyer.
Create shareable urls for videos so they can be posted on twitter and other social media as an integrated video. For example, if I post a vimeo or youtube video profile page url into twitter the video preview page is shown.
