You can make your post title looking like this: <a href="https://url-to-site-you-want-fwd-viewer-to">Cool video</a> but you need to be prepared for reactions of not really happy users who after clicking on post title were sent somewhere outside your site ;).
I guess it’s better to write the tilte as usually and within post content write: Click on <a href="https://url-to-site-you-want-fwd-viewer-to">this link</a> to watch some cool video.
