Ask HN: What makes a good product demo video?

Thank you for putting forward the great question!

My experience is to launch with a series of videos according to what stage the launch will be and where to present the product:

1. Product landing page (1 min - 1.5 min): short video with the essentials or core uses cases as you mentioned

2. YouTube: multiple demo videos for each of the deep features. Each one last for 1.5 min - 2.5 min

You can start from the short ones and gradually move to the longer ones as you get more experiences

Have a look at this YouTube channel for the examples that last from 1 min to 2.5 mins: https://www.youtube.com/@Fluxcut-2026

Those demo videos are by Fluxcut at www.fluxcut.dev which can save you product launch lots of effort and time!

BTW, the demo video in the landing page of Fluxcut is made by Fluxcut.

For your convenience, two essential demo videos on Fluxcut:
