How to Create an AI Video: Describe What You Actually Want

To create a video with artificial intelligence, the process is simple: you describe the scene in a few sentences, pick a visual style, and the tool generates your clip. With Kiin’s AI video generator, the whole process takes just two steps.

What separates a great, usable clip from an attempt you have to redo is almost always the first step: the quality of your description.

Selecting a style takes a single click. Taking an extra thirty seconds to craft a thoughtful description, on the other hand, changes everything. That is where most of the final output is decided.

How do you create a video with AI?

The core principle is the same across most tools, and Kiin keeps it as streamlined as possible:

1. Describe your video: what is seen on screen, where it takes place, what moves, and the overall mood.

2. Pick a style: cinematic, photorealistic, anime, 3D, vintage, dreamy, and more.

3. Download your clip once the generation is complete.

Selecting a style and downloading your file require no effort. Drafting the description, however, is worth a closer look.

Why the description matters more than the style

The style determines how the video looks. The description determines what actually happens. A stunning cinematic finish will never rescue a vague or confused scene.

When a prompt stays too vague, the AI fills in the blanks using generic defaults: a standard background, an ordinary movement, and a neutral atmosphere. The clip turns out fine, but nobody looks at it twice. Conversely, every specific detail you provide is one less decision the AI has to make for you.

The 4 parts of a good description, one by one

Our guide to the 10 AI video styles sums up the formula: subject, setting, action, mood. Here's how to fill in each one.

1. The subject: who or what, exactly

"A dog" leaves everything open. "An old Labrador with a graying coat" creates a clear image instantly. Add one or two visible traits (age, color, material, clothing) and stick to a single main subject. Having two characters perform two separate actions in a short clip is already a complex task for a few seconds of AI video.

2. The setting: where, and when

The location alone isn't enough. Time of day and lighting completely transform a scene. A kitchen at sunrise and that same kitchen under flickering fluorescent lights at midnight tell two completely different stories. One detail about the light often does more for the result than three adjectives.

3. The action: one, and visible

Use verbs a camera can film. "He thinks about his life" cannot be seen on screen. "He looks out the window, then lowers his eyes" can. For a short clip, one main action is enough, followed at most by its direct consequence.

4. The mood: the tone in a word or two

Calm, tense, joyful, melancholic, mysterious. Pick a single direction and keep it. Stacking five conflicting adjectives dilutes your intent instead of strengthening it.

Before-and-after examples

A social media clip

• Before: "a video of coffee in the morning"

• After: "A young woman in an oversized sweater opens the curtains of a small kitchen at sunrise, golden light floods the room, soft and quiet mood."

The short version gets you an anonymous cup of coffee on a table, somewhere. The detailed version gets you a moment, with a gesture and natural lighting that make people stay.

A product ad

• Before: "an ad for sneakers"

• After: "A pair of white sneakers on wet concrete, on a city street at night, a drop of water falls and splashes the sole, urban and energetic mood."

Notice that it describes the physical product itself, not a specific brand. That works better for the AI model and is much safer for you legally.

A short story scene

• Before: "a child discovering magic"

• After: "A little boy in pajamas walks into a dusty attic lit by a flashlight, lifts the lid of an old trunk, and a blue light spills out, mysterious and wonder-filled mood."

"Magic" is an abstract idea. A glowing blue light spilling out of a trunk is a cinematic image.

The mistakes that ruin an AI video

• Too many ideas in one clip: a change of location, three actions, and a plot twist won't fit into a few seconds. Stick to one core idea per clip; if your story has several, generate multiple clips.

• Abstract words instead of concrete visuals: "success," "freedom," and "innovation" cannot be filmed directly. Ask yourself what those concepts look like in real life, and describe those physical elements instead.

• Contradictory elements: a sunny night or a scene described as both calm and frantic will confuse the AI model.

• On-screen text inside the prompt: AI video generators are still unreliable at rendering readable text. Add your titles and captions in video editing instead.

• Real people, brands, or protected characters: avoid them without explicit permission, and describe generic characters or products instead. This is the exact type of compliance issue that weighed heavily on Sora's shutdown.

What if the clip doesn't match what you pictured?

Adjust one element at a time. If the subject comes out wrong, make the subject description more specific. If the mood feels off, rework the light and the mood words. If you change everything at once, you won't know what made the difference.

And if the content of the scene is right but the aesthetic look isn't, keep your description exactly as it is and simply switch visual styles. The styles guide helps you choose by use case.
