Something that I'm trying out is to not just end videos so that they loop like I'm sure you've seen. But write the script so that the pay off is actually the hook.
One of the videos I'm writing starts "is psychology why faceless videos still get 10M views..." (This mirrors the audiences inner dialogue)
And the video will end: "So, clearly there..."
I'll comment the video and the metrics of this video once I upload. So you can see how well it does.
But it could be something to think about in your own content.
