Let me be honest about where I started. My very first prompt was something like "a cat in a city." That's it. Four words. And the result was… fine, I guess? A cat. A city. Zero personality. It looked like a stock clip someone forgot about.

The problem wasn't the AI. These tools are genuinely impressive now. The problem was that I was giving it almost nothing to work with and somehow expecting magic back. Once I understood that a prompt is really just a set of instructions — the more specific, the better — everything got easier. So this is the guide I wish I'd had on day one.

Why your first prompts probably feel flat

Here's the thing nobody tells beginners: AI video tools don't "imagine" the way you do. When you picture "a cat in a city," your brain fills in a hundred details automatically — the time of day, the mood, whether it's raining, how the camera moves. The AI doesn't get any of that unless you say it. It just fills the gaps with the most average, generic version of your words.

So the real skill isn't writing fancy prompts. It's learning to say the parts your brain was keeping to itself.

The simple structure I use every time

You don't need to memorize anything complicated. I basically run through five things in my head, in this order:

  1. Subject — who or what is this about?
  2. Action — what are they doing?
  3. Setting — where, and what time of day?
  4. Camera — how does the shot move? (This one's a game-changer.)
  5. Mood & look — lighting, colors, the overall feeling.

That's it. If you hit those five, you're already ahead of most beginners. Let me show you the difference on that sad little cat prompt.

❌ Before a cat in a city
✅ After A fluffy orange cat sitting calmly on a rain-soaked window ledge at night, looking out at a glowing neon city. Slow push-in toward the cat's face. Moody, cinematic lighting with reflections of pink and blue neon in the wet glass. Shallow depth of field, quiet and dreamy.

Same idea. Completely different result. And notice I didn't use any technical jargon — I just described what I actually wanted to see, one layer at a time.

Quick tip: The camera line is the one most beginners skip, and it's the one that instantly makes videos feel less "AI." Even something simple like "slow push-in" or "gentle pan from left to right" adds a huge amount of life.

The small tweaks that made the biggest difference

1. Name the lighting

"Golden hour," "soft morning light," "harsh overhead neon," "warm candlelight" — lighting sets the entire mood, and it's a single phrase. Honestly, if I could only add one thing to a weak prompt, it'd be this.

2. Pick a color palette

Saying "warm oranges and deep browns" or "cool blues and silver" keeps the whole clip visually consistent. Without it, the AI sometimes throws in colors that clash and the video feels a bit chaotic.

3. Describe motion speed

Is it slow motion? Real-time? A quick, energetic burst? "Slow-motion" alone can turn an ordinary clip into something that feels intentional and premium.

4. Stop overloading it

This one took me a while. Early on I'd cram in twenty things — three characters, five actions, a whole storyline — and the AI would panic and do all of them badly. Short AI clips are usually a few seconds long. Give it one clear moment, not a movie. Less really is more here.

A mistake I made for way too long

I used to blame the tool when a video came out wrong. "Kling can't do hands," "Runway doesn't get what I mean." Sometimes that's true — these tools do have limits. But nine times out of ten, when I went back and actually read my prompt, it was vague. I'd written "a person walking" and gotten annoyed that the person didn't look how I imagined. Well… I never said how they looked.

So now, before I complain, I re-read my own prompt and ask: did I actually describe this, or did I just assume it? That single habit fixed most of my problems.

You don't have to write these from scratch

Here's the part I'll be upfront about: writing a full, detailed prompt every time gets tedious, especially when you're still learning what "good" looks like. That's actually why this whole site exists. You can describe a rough idea, or upload an image or a short clip, and the tool builds the detailed, structured prompt for you — with the camera, lighting, and mood already filled in. Then you tweak it to taste.

It's a nice way to learn, too. Seeing how the tool expands "a cat in a city" into a full prompt taught me more about structure than any tutorial did.

Try it on your own idea

The short version

If you remember nothing else: be specific, name the camera and lighting, and keep it to one clear moment. Do that and your very next prompt will already be better than 90% of what beginners write. Everything after that is just practice and taste — and those come with time.

Now go make something. Your ideas are better than "a cat in a city." Prove it. 🙂
