I work on slideshow creation software for funeral homes. Stories like yours are something I worry quite a bit about, since we've found that once users trust our software, they stop bothering with the preview. We let the user choose custom zoom points but don't yet incorporate face recognition. As far as I am aware, none of our competitors have face recognition or even face detection. Some funeral homes hire or outsource to a local videographer instead of using purpose-built software. It's possible that the videographer could have used a slideshow plugin with that feature and then combined it with the stock footage.
