A poster frame is a static image taken from one frame of video to represent a video (like a video post) visually in various contexts such as a thumbnail or before the video is played.

Why

You should include an explicit poster frame on your video posts to provide an image that is representative of what the video is about, since the first frame might not show much, or is blank.

How

Use the HTML5 poster attribute on the <video> tag with a URL to the poster frame image like a JPEG.
