Wan 3.0 Video to Prompt
Read any clip back into words

Give it a clip and get back the Wan 3.0 prompt that would produce something like it — written in Alibaba's own order, not a generic caption. The clip is opened in this browser: what crosses the wire is a sheet of frames and a compressed audio track, never your file.

Your Wan 3.0 prompt

descriptionsubject · scene · motion · camera
soundwhat the scene makes
musicor no music

Three sections, flattened into the one plain paragraph Wan 3.0 reads. The labels belong to this panel, never to the prompt.

Before you copy

A style is fair game; a recognisable work is not.
Real, identifiable people need consent.
Describe a mood and an instrumentation, not a specific song.

Responsible use

Generating needs an account, and the first clip on it is free: 480P, up to three seconds, with sound.

What it costs

Free reads, counted honestly

The tools that rank for this charge two to ten credits a go, from a pack you buy before you have seen anything. This one gives you a read a week without an account and three a week with one, and only starts charging after that — five credits, which is an eighth of the cheapest Wan 3.0 clip you could generate here.

It is metered because reading a clip is not free the way writing text is. Every run decodes frames, transcribes the audio and puts a vision model over the result. That is a fraction of a cent, not nothing — so rather than print "no counter" and then quietly refuse you on the fourth try, the number is on the button before you press it.

Free, up to the weekly count

720P and 1080P, and anything longer than three seconds

No card to start, and nothing here bills by surprise: the extractor prints its own price on the button, and a run that fails hands the allowance back.

What comes back

What it reads out of a clip

Rather than one paragraph of description, the result arrives in the layers a Wan 3.0 prompt is composed from — so you can keep the parts you want and rewrite the rest before anything is generated.

EntityThe subject, described as something Wan 3.0 could re-shoot rather than as a caption.
SceneLocation, time of day, and where the light is coming from — the layer Wan 3.0 invents for itself when a prompt leaves it out.
MotionWhat moves, how far and how fast — stillness counted as a choice.
Aesthetic controlShot size, camera move, apparent lens and depth — the layer Wan 3.0 follows most literally.
StylizationA named look, only when the footage clearly has one.
SoundSpeech, effects, ambience and score — and silence, where it is deliberate.
…flattened into one paragraphWan 3.0 takes a single plain prompt, so the layers are the panel's labels and never reach the model.

Speech is transcribed, not guessed

The audio track is transcribed rather than described, so a line of dialogue comes back as the actual line — already inside braces, which is the only way Wan 3.0 performs a line instead of narrating it. If the clip is silent, the result says so rather than inventing a soundtrack for it.

she looks up and {It stopped raining.}

Then it goes through the same checks

The prompt comes out of the reader and straight into the twelve rules the prompt writer uses — the character ceiling, the case-sensitive citations, the camera move that names neither size nor speed. A read that produced something Wan 3.0 would mangle says so before you copy it.

12 rules, run before you copy

Five reasons to read a clip

Five things people take from a reference clip

Naming the target changes which part of the read matters most, and what the Wan 3.0 prompt leads with. It is asked before the run rather than offered as a filter after it.

Style
style
Grade, light, texture — the look before anything moves.
Composition

Framing and blocking: where things sit and how the eye travels.
Motion

Choreography and camera path, written as a move with a size and a speed — the only camera grammar **Wan 3.0** executes.
Sound

The mix that makes it feel expensive, split the way Wan 3.0 takes it.
Character

Who is on screen — and the one goal that starts with consent.
Likeness line, below

A dance clip and a perfume ad might share a grade, but you would read them for opposite reasons: the first for its motion, the second for its light. If what you actually want is to keep the original framing or soundtrack rather than describe it, stop here and hand reference to video the file itself — Wan 3.0 carries up to five reference clips in one request, and a copy beats a description every time.

How the read works

Your file never leaves the browser

Most tools of this kind upload your video. This one opens it locally, decides what is worth looking at, and sends two small artefacts to build the Wan 3.0 prompt from — which is why the progress bar names the machine each second is being spent on.

Step 01Opened on your machine
Decoded in the tab, through the browser's own video pipeline. Nothing has been sent at this point, and nothing will be if you change your mind.
Local decode
Step 02Scanned for cuts
Four samples a second, looking for frames that change more than this particular clip normally does. A handheld single shot and a six-cut montage need different thresholds, so the bar comes from the clip itself.
4 samples / second
Step 03Built into a contact sheet
Six frames without an account, eight with one, laid out two wide. Cuts are claimed first so no shot goes unseen; the rest spread across the widest gaps.
6 or 8 frames
Step 04Audio compressed, not uploaded whole
The track is re-encoded small and sent alongside the sheet. If the browser cannot do it — Safari, most often — the read still runs, and the result says the sound was inferred rather than heard.
~24 kbps Opus
Step 05Watched and listened to
A vision model reads the sheet while transcription reads the track, and both land in the same prompt: what is on screen, and what it sounds like.
Sheet + track
Step 06Composed in Alibaba's order
Entity, scene, motion, aesthetic control, stylization — flattened into the single plain paragraph Wan 3.0 actually reads, with the sound written alongside rather than after.
One plain prompt
Step 07Checked before you copy
The same twelve rules the prompt writer runs, failing line quoted. A read that produced something Wan 3.0 would render as on-screen text is caught here rather than in a paid generation.
12 rules

The pass others skip

The three sounds your clip is making

Keyframe tools sample stills, which means they analyse your clip on mute.

This one listens, and splits what it hears three ways — because Wan 3.0 generates audio in the same pass as the picture, so the prompt is also the sound brief. The test between the last two is one question: could the people in the clip hear it?

Dialogue
The words people actually say, transcribed and placed inside braces in the shot they belong to. Who says it and how they say it stay outside the braces, in the prose.
{It stopped raining.}
Soundscape
Everything the scene itself produces: rain on an awning, a knife on a board, traffic two streets back — each with a distance and a moment it lands.
sound
Score
What only the audience hears: instruments, tempo, where it enters and where it resolves. A clip with none comes back saying so, and "no music" is itself an instruction Wan 3.0 obeys.
music

Say nothing about sound and Wan 3.0 still generates some — chosen by the model. That is the argument for reading it off the reference rather than leaving the field blank.

Length

A 60-second clip does not become a 60-second prompt

Wan 3.0 generates two to thirty seconds, and your reference probably is not that.

What it will readup to 60s of source
What Wan 3.0 generates2–30s at 30 fps

Pick a target length and the read is fitted to it. When the source is longer than the target — which is most of the time — the tool stops and asks instead of quietly reading the first eight seconds of a thirty-four-second video and never mentioning it.

Two ways to answer: take one contiguous stretch and drag it to where the good part is, or keep the whole clip and let it be compressed, vetoing the beats you do not want. The second is a genuinely different instruction — the model is told these frames span the whole clip and asked to compress, not to describe a window — and getting that wrong is what produces a timeline of one-second shots that nothing can execute.

The beats it found are drawn on a strip you can click, so the machine's taste is a suggestion rather than a decision.

Where the line is

Whose video is it?

Reading a clip does not give you rights to it, and we cannot grant rights we do not hold.

StyleLearning that a clip leans on golden-hour light and a slow push-in is fine. A style is not something anyone owns.
A specific workRebuilding a recognisable film or advert shot for shot is not, however the rebuild was made.
A real personDescribing a real, identifiable person into a model needs their consent, and reading their face off a clip does not obtain it.
MusicDescribe a mood and an instrumentation. Reconstructing a specific song is a different act with a different owner.
Logos and productsProtected no matter how the video was made. The practical test: if you would not put that clip in your own ad, do not rebuild it here either.

Full policy: Responsible use

Take the prompt to the generator

The prompt is plain text and it is yours — paste it into anything. But the shortest route from here is the button in the result panel, which carries it into a real Wan 3.0 generator on this site with the length and the aspect ratio already set to what you read it at.

01
Read it, then edit it
Every section is yours to change, and the checks re-run on what you leave behind.
02
Press the button in the panel
Prompt, length and ratio travel together, so nothing has to be re-typed.
03
Generate
This part needs an account, and the first clip on it is free: Wan 3.0 itself at 480P, up to three seconds, with sound.

Open text to video

A prompt is a description, and a description is lossy on purpose. If the goal is keeping the original rather than re-making something in its spirit, the file itself is the better input.

Honest routing

Describing a clip is lossy on purpose, and when the goal is learning why it works the loss is the point. When the goal is keeping the original framing, lighting or soundtrack, stop describing: reference to video preserves what a rewrite can only approximate, and re-voicing or continuing real footage is video editing's job.

The one case where a description is the only path is a source you cannot upload at all — someone else's footage, or private material — because a description you wrote is yours in a way a copy never is.

Questions people actually ask

Wan 3.0 video to prompt questions

Ten answers · all visible · nothing collapsed

What does Wan 3.0 video to prompt actually do?

It reads a reference clip — the frames and the audio — and writes back the single plain-text prompt that could produce something like it, composed in Alibaba's published order and checked against the twelve rules Wan 3.0 imposes.

Will I get the exact same video back?

No, and nothing will. Wan 3.0 exposes no seed to replay, and a prompt is a description rather than a recording. Expect the same register — same subject type, same camera language, same sound design — and treat it as a strong first draft.

Is Wan 3.0 video to prompt free?

One read a week without an account, three a week with one. After that it is five credits a run, which is an eighth of the cheapest Wan 3.0 clip you could generate here. The button says which of those you are about to spend before you press it.

Why is this one counted when the prompt writer is not?

Because they cost different things. Writing a prompt is one text call and a fraction of a cent. Reading a clip decodes frames, transcribes audio and runs a vision model over the result — small, but not small enough to promise without limit and then refuse you on the fourth try.

What can I give it, and how long can the clip be?

A direct link to an MP4, MOV or WebM, or a file of up to sixty seconds — comfortably more than the thirty Wan 3.0 generates. Anything longer than the target length you pick brings up a picker, because reading the first few seconds of a long video and not saying so is the failure this control exists to prevent.

What happens to my upload?

The file itself is never uploaded. It is opened and decoded in your browser, and what crosses the wire is a sheet of six or eight frames plus a compressed audio track. There is no video of yours on our side to keep.

Does it transcribe the dialogue?

Yes, and the line comes back inside braces — the form Wan 3.0 performs rather than narrates. If the browser could not compress the audio, or the clip has none, the result says which of those happened instead of inventing a soundtrack.

My reference is six seconds. Can I get thirty?

You can pick thirty as the target and the Wan 3.0 prompt will be written for it. Be careful with it: a six-second idea does not always contain thirty seconds, and padding a thin idea is a fast way to spend credits on a clip that sags in the middle.

Can I read a clip from social media?

Technically it will read one. Whether you should is what the rights section above answers, and for someone else's work the answer is usually no — reading it grants you nothing, and we cannot grant what we do not hold.

Can it go the other way — idea to prompt?

That is the prompt generator, this tool's mirror image, and it has no weekly count. Write there when you have an idea and no footage; read here when you have footage and no words.

Give it a clip, read it back as a prompt.

The file stays in your browser, the first read each week costs nothing, and what you copy is yours. Generating it on Wan 3.0 takes an email — and the first clip is on us.
