This is my first attempt to make video with AI.
WOW! I tested RUNWAY (for now just the free version), starting on some Midjourney images of mine and doing my best to add some simple movement. Just for fun (the last famous words… 🙂 ).
The results look pretty promising, – at least to me – although the free version doesn’t allow movies longer than a few seconds.
Here I used this image 
and a quite generic prompt “(scuba floating gently away under water with fishes)”.
And here… voilà Charon’s boat stuck in a hellish cave while the souls of the dead are waiting…
In this case I used the brush option to show where and which elements of the image should be involved in the motion: astounding! intuitive, quick and easy. Easier than by prompt.
