This kind of issues is what I'm constantly coming across. Say I'd like to say something like this.
In the middle of the video, a ghost pops up from nowhere.
What I'm confused is whether I should add the in front of video. I thought maybe? it could be redundant because there is already an article before middle, but I'm not sure because that article is for middle, not for video.
To put this question more generally, can I ever omit articles if there is another article in the same noun phrase?
