Youtube video preview on hover?

Question

YouTube

What is the right way and how to implement it?
The client saw this feature on YouTube and now wants it to be the same on the site. There is a list of news with preview pictures and how can I implement them on hover so that they look like a GIF? If I understand correctly, this is a gif. But when you switch to this news, the YouTube player with the video is already inside

Answer 3

If you need a gif, then generate a gif from a piece of video and insert it under the picture, hide the picture on hover, and the gif will become visible, instead of a gif, there can be a piece of video that is stored on the server. But making gifs or pieces for each video is somehow expensive.
Instead of a gif, you can insert an iframe with a video from youtube, hover over the picture and start playing the video (youtube iframe api). There is nothing complicated there.
