What you’re talking about is the primary marketing collateral. But any good marketing campaign needs a ton of secondary or even tertiary marketing collateral

The first “real video” you talked about is meant to grab attention and tell users, honestly, what the product is about

But they’re not customers - yet. They need to be reminded about your brand again and again

You can’t run the same video every time - for one, its repetitive. And for two, its disruptive on the wrong channels

You will need static images and basic videos and even tweets across platforms to remarket to your audience

That’s where tools like this come in handy. You grabbed attention with the first video. But now you need to tell users that if they buy tomorrow, they get 15% off.

I think you might be seeing guys who do that well so it's a bit survivorship bias. For most, if you just record yourself talking for 1m and watch it back as a video it's incredibly painful and awkward. The filler words, tangents, weird pauses. It really made me have respect for great speakers

This works for the subset of people who have a good story or a real connection to their brand, but that's just not most businesses. I buy and operate e-commerce brands, and I can't do it both because I really don't want to be on camera and because "hey I bought this company that sells leather handle covers for cast iron pans, and I personally don't use them but the cashflow was good" is not so compelling as a message. Sometimes you just need messages that convey the value proposition of the brand. (And FWIW they are nice handle covers, I just prefer to use a kitchen towel to grab my cast iron.)

That said, I think video generation is at the point where someone will probably develop a product that fakes the kinds of videos you're talking about in the near future.

Yes but those guys need their marketing to work. Most marketing people just need to spend a budget. For those guys now they can pump out infinite crap to spend their budget so that you rEMemBeR tHeM lATer.
