MLA citation style
In-text citations - Audiovisual resources
Audiovisual recordings such as videos and songs do not have page numbers to be included in in-text citations. For such time-based media, you should include the time or range of times for any segment you are quoting or discussing.
Example:
Near the beginning of the film, a woman tells Johnnie that Lina is “a very carefully brought-up young lady” (Suspicion 4:50).
