This is been one of my go-to video AI tools for months. Easy to use text and image to video, with plenty of other functions also: camera control, aspect ratio, and fun templates.
I really like the Haiper 2.1, but it is also great to do unlimited on 1.5 to see if it is the right look for the scene. I have done a couple short films using only Haiper and people like them.
Haiper has its own unique personality. It can be a nifty companion that brings new inspiration to the creative field. I am the most satisfied with Haiper and love it the most out of all the AI generators I've tried.
