Hello. You did not inform the video to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
In a video, the speaker is the one who is narrating the video, presenting the information that the video contains. To determine who the speaker of the video is, you must identify how that speaker is related to the context of the video, that is, if this vice is talking about science, the speaker can be a scientist, a teacher or a researcher. If the video talks about theater, the speaker can be an artist, an actor, a director, or another professional related to it.
First person. The only exception is if they are talking about someone else. Or whiting about someone else
The movie theater is the subject.
The theme is used to convey the message/lesson of a text. For example, the lesson of “The Tortoise and the Hare” is that slow and steady wins the race. Therefore, the theme of “The Tortoise and the Hare” is that slow and steady wins the race. Hope this helps!
