Ignoring videos in macOS Photos

Is it possible to do this using Applescript? I currently have 110 albums, and will probably need to export them repeatedly as I slowly organise them better, so doing it by hand would be laborious to say the least.

Thanks Richard, but it looks like I'd have to create a separate smart album for every existing album in Photos, and that's too onerous a process for me. I did do an export script in the end that ignores files with certain extensions, which seemed the best way of excluding movies from the export.
