Launching in two days with screenshots only. Is a demo video worth the rush?

My Product Hunt launch is in two days. The gallery is ready, but it's all screenshots: a hero image and a few shots of the product in use. I don't have a video. I could spend the next two days recording one. I'd rather spend that time on the first comment and on replying to people on launch day, though, and I'm not sure a rushed video helps more than it hurts. If you've launched before, did your video actually change anything? Or did most people just look at the first image and read the tagline?
