You are only talking about followers I think but I beleive if someone can just post video just to get the attention of people then how earn do you that they will be able to earn?That is certainly one of the ways most persons do make their money on social media,they post recreational videos,educational,health and anything that you can use to gain followership online,and then you can be lucky to get huge followers.
Rather I think that you will need to attached something with the video which can also help you to earn
