Video prompts cannot rescue a bad reference image or bad starting frame.
If that frame is wrong, every second after it is a negotiation with a mistake.
Before generating videos, take time to brainstorm by generating varied images, varied styles, or using references.
You can also generate many images of the same character/item/place but change one single thing: e.g., the style of armor, the shape of an island, the scar on a character’s face.
