One camera move
Two moves at once is the single most common cause of an incoherent clip: the model attempts both and commits to neither. If you want a compound move, generate two clips and cut between them.
MOTION PROMPTS · ONE MOVE AT A TIME
Image-to-video prompt generator
Describe the motion, not the picture. Pick one camera move, one thing the subject does and one detail of the world, and this builds the prompt in the order a video model reads best.

THE METHOD
Three mistakes cost more credits than everything else
A motion prompt rarely fails for want of a better adjective. It fails in one of three specific ways, and this tool names each of them back to you rather than quietly rewriting your words.
No completed events
A clip that has to finish something inside its duration either rushes it or is cut off. "Candle flickering" behaves; "candle goes out" is a gamble against the clock.
Do not re-describe the image
The model can already see your start frame. Every word spent on what is in it is a word not spent on what should move — which is the only thing it needs from you.
PAST THE PAGE
A prompt is half of it. The frame is the other half.
Starting from an image fixes the composition, the colour and the subject before generation begins. That is why image-to-video usually takes fewer attempts than describing a whole scene from nothing — and why the prompt only has to carry the motion.
- Bring your own still, or pull one out of footage with the frame extractor.
- Draft at 360p for 20 credits, then re-render the take you want at 1080p for 125.
- A free account starts with 200 one-time credits, which covers several drafts and a finished clip.
This page is free and needs no account. Generating video is a billed mode, priced above.

Motion prompts, answered
Is the prompt generator free?
Yes, and there is no account. It composes text in your browser — nothing is generated and no request is made, so it costs us nothing to serve. Generating the clip from the prompt afterwards is separate and billed.
Why only one camera move?
Because a model given two will attempt both and commit to neither, and the result reads as a camera losing its balance. It is the most common cause of an incoherent clip. For a compound move, generate two clips and cut between them — which is also how it would be shot in reality.
What clip lengths can I ask for?
Clips run 4, 6, 8 or 10 seconds and nothing in between. A request for 5 snaps down to 4, which is the usual reason an ending gets cut off. Six is the default and suits most single camera moves.
Can I use a negative prompt?
There is no standalone negative-prompt field in the Video Studio, so phrase things positively instead. "Static camera" works better than only saying "no camera movement", and both together work better still.
Can I add a style reference as well as a start frame?
No — frame modes take frames only, and a separate style or character reference cannot ride along in the same request. Build the style into the source image first, which is cheaper anyway: fixing a look in a still costs an image rather than a video.
Will a prompt work on a photo of a real person?
No prompt will, because the refusal is not about wording. Image-to-video rejects raw photographs of identifiable real people deliberately — that is a consent boundary. Generated portraits, illustrated characters, products, animals and places all work.
The studio behind this tool

Video Studio
Turn a prompt or a still image into a moving clip, in vertical or widescreen for wherever it ships.
Character Studio
Design a character once and reuse them consistently — the same face in new images, scenes, and clips.
Storyboard
Plan a video scene by scene, then send each shot to the studios to render.
Music Studio
Write full tracks with vocals or instrumentals for your videos and streams.
