I don’t remember if it was someone here or on YouTube, but someone achieved this exact idea before, so it is definitely doable without voice Ai or anything.
EDIT: I did find a version of this idea. https://www.youtube.com/watch?v=5GvpT_7BMAc
The scene is very good, but unfortunately the music is not the same, so I don’t think this scene could be used in an actual edit. We would need to change the whole score.
Huh? Of course it could be used in an edit.
Also, changing the score is what fan edits do best! - well, maybe not BEST…but they do it. 😛
