Fade to black and vice versa

[adhirajghosh]

Hi,
Thank you for open-sourcing this great work.
I am trying to execute a video format where I would like to interpolate from a black screen(image) to a certain prompt and then interpolate to a black screen again. Is there a way to implement this?
Additionally, I understand it is bad practice to predefine the init_noise params, but what would be the method to replace it with feature embeddings of images? I implemented the same but I get hazy images as shown in the image attached.
