This depends on which citation style you are using. Below are examples for both MLA and APA style.
MLA: YouTube Video
Video and audio sources need to be documented using the same basic guidelines for citing print sources in MLA style. Include as much descriptive information as necessary to help readers understand the type and nature of the source you are citing. If the author’s name is the same as the uploader, only cite the author once. If the author is different from the uploaded, cite the author’s name before the title.

APA: Blog (Weblog) and Video Blog Post
Include the title of the message and the URL. Please note that titles for items in online communities (e.g. blogs, newsgroups, forums) are not italicized. If the author’s name is not available, provide the screen name.
