Why does my youtube video have a picture of a camera with a clock thing on it.?

how can i change that? whenever i see videos they dont have a white camera on it. it usually has a still from the video on it. when i go to choose a still... all it shows is that camera. how can i fix this?

In a while, the camera with the clock will change to a still image of the video. Just go for a bike ride or a swim and come back, and see if it is there yet!
