Every YouTube video resides on its own page and has a unique URL. YouTube creates HTML meta tags for each of these video view pages based on different page elements.
The title of the video becomes the title tag, the description becomes the meta description tag, and the YouTube tags become the meta keywords tag (never mind that this tag is ignored by most search engines).
Therefore, writing a good title can vastly affect your video’s click-through from both YouTube and from non-video SERPs.
