I think it highly depends on your product. Main question: is your product easy to understand by others?
Before investing time in making this video I'd do a little bit of user research.
1. Ask people if they understand what the product does.
You could show it to random people, friends, family.
2. Run a survey on the website - simple question with thumbs up / thumbs down asking "Would you know how to do X with our product"
3. Do a smoke test: add a link in the hero section "I'd like to watch tutorial" and then see how many people actually click on it. There could a message after clicking "We are working in the tutorial, please come back shortly" but you will know if the want it or not.
4. Additionally if you have high bounce rate and people spend very little time on the website, chances are they don't really understand it
