Mercury aims to get YouTube videos to the same level of user engagement as livestreams. It’s equipment include dynamic thumbnails, dynamic description, and screen-and-taste! As it turns out, the two old ones add real time data to both video thumbnails and descriptions. Similarly, to thumbnails, this can be data on charity goals and merch sails, or shoutouts from the subscribers or supporters. Dynamic descriptions can include live streams, supporter spotlights, and community-wide statistics. Other tools include on-screen shout-outs for supporters, including YouTube subscribers, Patreon backers or discord members. StreamElements sends users an email tailored for the weekly email with a performance summary. StreamElements has updated 350 channels to find out if these kinds of updates can make even older videos more engaging for viewers, according to StreamElements. Sergey Bukhman, product manager of Mercury, said in a statement that by offering dynamic descriptions and thumbnails, shout-out overlays and polls, the instant gratification has gotten the viewer better engaged, retention and growth. Since the idea proved obvious, the creators who used Mercury achieved a 60 percent increase in engagement on average. This is an important boost that validates our free tools as a compelling new layer to video on demand production. Mercury is free currently, and available on the StreamElements website, in beta.
