In the spirit of sheepish confession: that is my fault. I always tell founders to make raw, unprofessional videos for their Launch HNs. In fact, here is my standard blurb about it:

"What works well for HN [demo video] is short and direct, with zero production values. Skip any introductions and jump straight into showing your product doing what it does best. It should take only a few seconds before we see it in action, doing something cool. Voiceover is good, but no marketing slickness—no fancy logos or background music or anything like that!"

I can see how maybe this could be counter-grain for some enterprise products.
