Open source AI Video Generator

Hey!

For images I looked up on YouTube and found a way to use Stable Diffusion on Google Colab for creating AI images for free.

I wish to create a short movie that is 20 minutes long, and realized if I use runway and Kling it would probably cost me in thousands due to credit usage just to get the perfect videos.

Is there a stable diffusion for video generation that I can create at home without a powerful graphics card?

Any help would be greatly appreciated.
