I unexpectedly got free-to-me access to the BEST A.I. VIDEO generating tool as of May 2025 — Google Veo 3.
… It costs U.S. $250 / month as I post. 
I first asked for audio and video of a hiker crossing a river in a rain storm on Vancouver Island.
NEXT I was offered an A.I. enhanced version of that same prompt:
Atmospheric and moody cinematic scene, reminiscent of a Pacific Northwest indie film. Overcast day, with a soft, diffused light filtering through the dense canopy of evergreens. Cool blues and grays dominate the color palette. Medium shot of a lone hiker, seen from the waist up, mid-stream in a rushing river. The hiker is wearing a waterproof hiking jacket and a backpack. His face is partially obscured by the rain and the hood of his jacket. The river is rocky and fast-flowing, with the water churning around the hiker’s legs. The background consists of a lush, green forest with ferns and moss-covered trees. The camera slowly pans to follow the hiker as he makes his way across the river. The sound of the rain and the rushing water create a sense of immersion and isolation.
Finally, I changed the last enhance prompt to have the hiker in deeper water.

Whether we like it or not, A.I. video will be increasingly included in movies, television, and YouTube videos.
