How to Write AI Video Prompts

A director's recipe for Sora 2, Veo 3, Kling and Runway. The seven parts of a video prompt, a camera-move cheat sheet, and free copy-paste examples that actually move.

Short answer: a strong AI video prompt names seven things - subject, action, camera move, lighting, mood, style and shot length - then sticks to one clear action per short clip. Write it like a shot note you would hand a film crew, not a wish. Below is the full recipe, a camera-move table, per-model tips for Sora 2, Veo 3, Kling and Runway, and prompts you can steal today.

The anatomy of a video prompt

Think of a video prompt as a shot note. A photo prompt describes one frozen moment. A video prompt has to describe change over time, so it needs two ingredients a still image never uses: motion and a camera. Leave those out and the model guesses, and its guesses are usually stiff and boring. Here are the seven parts that turn a vague idea into a shot the model can actually film.

Here is the same idea written two ways. First as a labeled checklist, then folded into the natural sentence you would actually send.

Prompt recipe
[Subject]  a lone astronaut in a weathered white suit
[Action]   slowly turns to face the camera, then raises one hand
[Camera]   slow dolly-in from a low angle
[Lighting] harsh side light from a distant sun, deep shadows
[Mood]     tense, awe-struck, cinematic
[Style]    shot on 35mm film, shallow depth of field
[Length]   6 seconds, one unbroken shot
Same prompt, ready to send
A lone astronaut in a weathered white suit slowly turns to
face the camera and raises one hand. Slow dolly-in from a low
angle. Harsh side light from a distant sun casts deep shadows.
Tense, awe-struck, cinematic. Shot on 35mm film with shallow
depth of field. One unbroken 6-second shot.

You do not need the brackets when you send it. They are a checklist to make sure nothing is missing. Most models read best when you fold the seven parts into one or two natural sentences, in roughly that order.

Camera-move vocabulary

The single biggest upgrade to any video prompt is naming the camera move with real film words. "Cool angle" tells the model nothing. "Slow dolly-in from a low angle" tells it exactly what to do. Here is the vocabulary worth memorising.

Camera moveWhat the camera doesReach for it when
Dolly in / outThe whole camera glides toward or away from the subjectBuilding intimacy, or revealing the space around someone
Tracking / followCamera travels alongside a moving subjectWalking, running, chases, any forward action
PanCamera pivots left or right from a fixed spotRevealing a scene, or following motion across the frame
TiltCamera pivots up or down from a fixed spotRevealing height, looking up at something huge
Crane / boomCamera rises or lowers through the airEpic reveals and sweeping establishing shots
Orbit / arcCamera circles around the subjectHero moments and showing all sides of a thing
HandheldSubtle natural shake, a human holding the cameraDocumentary feel, tension, raw realism
Push inA slow, steady dolly straight toward the subjectRising emotion, a dawning realization
ZoomThe lens magnifies without the camera movingQuick emphasis (note: this differs from a dolly)
Static / locked offNo movement at all, a fixed frameCalm, composed shots that let the action carry itself
Whip panA very fast pan that blurs the frameEnergetic transitions between two moments

Rule of thumb: one camera move per clip. If you want a dolly-in and then an orbit, that is two shots. Generate two clips and cut them together, rather than asking one short clip to do both.

How to describe motion and pacing

Video models live and die on verbs. If your prompt reads like a photo caption ("a red sports car on a mountain road"), the model has no idea what should happen, so it barely animates. Give it a verb and a direction ("a red sports car speeds around the bend, spraying gravel") and it comes alive. Describe how things move, not only what they are.

Pacing is the second half. Speed words steer the whole feel of the shot. "Slowly", "gradually" and "drifting" give calm, floaty motion; "suddenly", "in a burst" and "snaps" give sharp, energetic motion. You can also call the tempo directly with "slow motion" or "real-time speed". Keep it to one main action per short clip. A five-second shot that tries to have a person sit, stand, wave, and walk out will look rushed and broken. Pick the one beat that matters and let it breathe.

Weak vs strong motion
Weak:   a waterfall in a forest, beautiful, 4k
Strong: water tumbles over mossy rocks in slow motion, fine
        mist drifting up into a shaft of morning light, ferns
        swaying gently at the edges. Camera slowly pushes in.

Tips for each model

The seven-part recipe works everywhere, but each model has a personality. Lean into its strength and your hit rate jumps.

ModelSignature strengthPrompt tip
Sora 2Physical realism and synchronized audioDescribe the sound and the physics out loud; keep to one clear action so the realism has room to shine
Veo 3Native audio, including spoken dialoguePut dialogue in quotes and name the speaker; add an ambient-sound line for the room
KlingSmooth motion and strong image-to-videoFeed it a start image and describe only the motion to add, not the whole scene
Runway Gen-4Consistent characters and creative controlUse reference images and keep the character description identical word-for-word across shots

Sora 2 and Veo 3: write the sound too

Because Sora 2 and Veo 3 generate audio along with the picture, silence in your prompt is a wasted opportunity. Name the sound effects, the ambience, and any spoken lines. Veo 3 in particular is strong at lip-synced dialogue, so give it real lines. Put each line in quotes and label who says it, then add a line for the background sound.

Veo 3 dialogue example
Two friends sit in a diner booth at night, warm neon glow
through the rain-streaked window. Handheld, shallow focus.

Woman (smiling): "You actually did it."
Man (laughing):  "I told you I would."

Ambient: quiet diner chatter, rain on glass, a coffee cup
clinks down. Warm, hopeful mood. 8 seconds.

Kling and Runway: think in motion and continuity

Kling is one of the best at taking a still image and moving it convincingly, so it rewards image-to-video prompts (see the next section). Runway Gen-4 is built for creators stitching several shots together, so its superpower is keeping the same character and world across clips. If you are making a sequence in Runway, copy the exact character description into every prompt so the model does not redraw a new face each time.

Image-to-video prompting

Image-to-video is the most reliable way to get a specific look. You make a strong still first (in Midjourney, FLUX, Nano Banana, whatever you like), then hand it to the video model as the opening frame. The rules flip here: because the model can already see the scene, you should not re-describe it. Describe only what should move and how the camera should travel. Re-listing the subject just confuses the model and can make it redraw things you already got right.

Image-to-video example (Kling)
[Start image: a knight in silver armor standing in a snowy field]

Snow begins to fall, the knight's cape flutters in a slow wind,
she turns her head to look off toward the horizon. Camera slowly
orbits to the left. Everything else stays still. Realistic motion,
5 seconds.

Notice the prompt never says "silver armor" or "snowy field" again. The image carries all of that. Some models, Kling included, also let you set a start frame and an end frame; when you have both, describe the journey between them ("the door swings from closed to fully open") instead of the objects.

Common mistakes

Free prompt libraries by model

The fastest way to learn the rhythm is to start from prompts that already work, then tweak them. We keep a free, copy-paste library for each of the big video models:

Questions

How do you write a good AI video prompt?
Name seven things: the subject, one clear action, a single camera move, the lighting, the mood, the style, and the shot length. Keep to one action per short clip and describe how things move, not just what they look like. Write it like a director's shot note, not a wish.
What is the difference between Sora, Veo, Kling and Runway prompts?
The structure is the same but the strengths differ. Sora 2 and Veo 3 generate synchronized audio, so you write dialogue and sound effects into the prompt. Kling shines at smooth image-to-video motion. Runway Gen-4 focuses on keeping characters consistent across multiple shots.
How do you describe camera movement in an AI video prompt?
Use real film words: dolly in, tracking shot, pan, tilt, crane, orbit, handheld, push in. Name one move per clip and say how fast it goes, for example "slow dolly-in from a low angle". Vague phrases like "cool angle" tell the model nothing.
Can I turn an image into a video with a prompt?
Yes. Start from a strong still image, then describe only what should move and how the camera should travel. Do not re-describe things already visible in the image, since the model can see them and re-listing them just causes it to redraw the scene.
