Made a dragon and used VEO 3 in Google Flow but it is only 720p, 16:9 with a watermark. I brought into After Effects and had to enlarge it to cover the watermark and set to 21:9. Don't recommend that part but it had the mist and ocean spray that I liked so I did with it. I made the focus on the dragons head and tried to keep it subtle. PDF of the steps to use in your own projects is attached.
