The reEmbed video player now supports HD video posters.
As time went by, we noticed that more and more users were embedding larger videos. As a result the default poster was being stretched and pixelated, spoiling the look and feel of the page.
The latest version of our player fixes this by selecting the best sized poster based on the size of the player. The fix took a bit more time to implement because we wanted to avoid forcing a high-res poster on every player, especially when the user was on mobile.
We feel that our solution (that decides on the fly what the best quality poster is) will provide the best user experience in both terms of look & feel and page load times.
