AI Text to Video Generator
Write the shot you want — subject, setting, camera move — and the model builds every frame. Nothing to upload.
- Prompt only
- Eight aspect ratios
- Up to 1080p
- Watermark-free MP4
How it works
Describe the shot, not the story
What comes back is one continuous take. Name the subject, the setting and the light, then say how the camera moves through it.
Set the frame before you generate
Aspect ratio and duration decide what the model composes for. Picking them first beats cropping the result afterwards.
Change one thing per run
Hold the prompt and switch model, or hold the model and rewrite one clause. Moving both at once leaves you unable to say which change did the work.
What people use it for
Storyboards and animatics
Turn a written beat into a moving reference before anyone books a camera or a location.
B-roll nobody filmed
Fill a gap in an edit — a street at dusk, steam over a cup, traffic seen from above.
Social openers
A vertical clip built from one sentence, ready to sit under a hook while the voiceover starts.
Concept exploration
Run the same sentence through all three models and compare motion, colour and pacing side by side.
Available models
All three models generate from a prompt alone. The parameter bar filters itself to whatever the selected one supports.
Seedance 2.0 Pro & Fast
Pro leads on fidelity and on holding a face together across a shot; Fast gives up the 1080p tier for a quicker turnaround. Both accept an end frame.
- 4–15s
- Pro up to 1080p
- End frame
HappyHorse 1.1

Other ways to generate
Image to video
Upload an image and it becomes the first frame, so the composition is decided before the model starts.

Upload reference images of a person or a product and the model keeps them recognisable across the clip.
