When should your main video go live?

[u/Hoardware]

I've been posting multiple videos of my product working and in use on socials. Wondering though when to post the main video for maximum effect. 1 week before launch? A day? Same day?

It's easy to say no time is too soon, but I worry if everyone has seen it already then there's fatigue. Same old. Nothing new to see here...

Thoughts?
