What makes a product demo actually feel good to watch?

I’ve been working on NovaCapture, a Mac screen recorder focused on making product demos feel more polished without spending hours editing.

I’m curious — when you watch a SaaS/product demo, what bothers you most?

• Choppy cursor movement?

• Too much zooming in/out?

• Hard-to-follow clicks?

• Poor audio?

• Too much editing needed?

Would love to hear what other makers and users think.
