The following is a video ad I put together back in May. It is intended to be used by a staging company and is targeted at real estate agents. The ad's total length would be 3-5 minutes which is pretty normal for this kind of ad. It is not laid out ready for a videography company to produce on purpose. I don't want you to have to wade through a bunch of producer jargon to understand this document.
The format I use for writing video ads allows me to produce them in a matter of a few hours given certain critical information such as offers, resources, etc. The below ad can also be translated into a sales letter quite easily.
