I think if you have any sort of talent that can be incorporated into a short creative video, it can only be helpful. Both of my kiddo’s submitted videos, one purely for their artistic talent and the other, a combination of two different elements. My kiddo’s last year had about 40 views on the private link, so I know it was watched (only applied to 3 schools, and got in to 1).
It makes you stand out, the people on the admission committee who have not met you have a face to a name.
