Poster previews
A static image shown before a video plays or when it is paused.
A poster preview is like a thumbnail for a video. It's a single picture that shows up before you hit play, or when the video is paused. This gives you an idea of what the video is about without having to start it.
For example, when you see a list of videos on a website, each one might have a poster preview. It helps you decide which video to watch next.
In video playback, a poster image is a static image displayed before the video starts playing or when it is paused. It serves as a visual placeholder and can convey information about the video's content. This is often implemented using the 'poster' attribute in HTML5 video elements.
