Practical guide
The biggest SaaS video mistake is trying to explain the entire product. Choose one audience and one job, then use the product website to support that story.
Define who is watching, what problem feels urgent to them, and what outcome would make them care.
A launch film can focus on a new capability; an outbound film can focus on a painful workflow; a homepage overview can explain category and value.
Use separate versions for different audiences, features, and channels rather than forcing every purpose into one short film.
