Why Choose This?

Image-to-video generation
Turn a start image into a generated video.
Optional prompt guidance
Describe the scene, action, camera movement, and mood for the video.
Last-frame guidance
Use last_image to guide the final frame or continuation direction.
Native audio generation
Generate synchronized audio together with the output video using generate_audio.
Flexible aspect ratios
Choose from 16:9, 9:16, 4:3, 3:4, 1:1, and 21:9, or let the output adapt to the input image.
Seed control
Use a fixed seed for more reproducible outputs, or -1 for a random seed.

Parameters

Parameter	Required	Description
image	Yes	Start image URL to guide the video generation.
prompt	No	Describe the scene, action, camera movement, and mood for the video.
last_image	No	Last frame image URL for video continuation.
aspect_ratio	No	Output aspect ratio: `16:9`, `9:16`, `4:3`, `3:4`, `1:1`, or `21:9`. If not specified, adapts to the input image.

Choose resolution — Select 480p, 720p, 1080p, or 4k.
Set duration — Choose a duration between 4 and 15 seconds.
Configure audio optional — Keep generate_audio enabled for synchronized native audio, or disable it if audio is not needed.
Set seed optional — Use a fixed seed for reproducible outputs, or -1 for random generation.
Submit — Generate the final video.

Example Prompt

A cinematic shot of the character slowly walking through a neon-lit street at night, soft rain falling, reflections on the wet pavement, gentle camera movement, atmospheric lighting, calm but dramatic mood.

Writing Effective Prompts

The input image sets the first frame — your prompt directs what happens from there. The clearer the motion and camera direction, the better the result.

1. Start from the frame

Describe the action that begins from your image: what the subject does, where it goes, how the camera moves. Don't re-describe what's already visible in the image — build on it.

The woman in the photo turns from the window and walks toward the camera; slow push-in, warm interior light.

2. Shot-by-shot timeline

For longer clips, break the motion into timed segments (1-second granularity), continuous, no gaps.

0-2s: She turns from the window, a faint smile forming. Camera holds. 2-5s: She walks toward the lens and stops mid-frame; slow push-in, shallow focus. 5-8s: She glances off-screen as light shifts from warm to cool. Handheld drift.

3. Consistency notes

Lock the look for the whole clip: camera style, lighting, palette, atmosphere, audio.

Camera language

Write these directly; the model understands them:

Shot size — extreme wide, wide, medium, medium close-up, close-up
Movement — push in, pull out, pan, track, follow, orbit, tilt up, handheld shake
Angle — low angle, overhead, eye-level, first-person
Techniques — one-shot / long take, dolly zoom, bullet time, speed ramp

For a niche term, add a plain-language gloss: "rack focus: the sharp foreground softens as the background comes into focus."

Referencing uploaded assets

When you attach images, videos, or audio, bind each one explicitly in the prompt by its upload order — @image1, @video1, @audio1 — and say what it's for. Don't rely on labels drawn inside the image itself.

"The knight in @image1 walks through the castle in @image2."
"Refer to @video1 for the camera movement only; keep its shot order."
"@image1 and @image2 are Character 1, voiced by @audio1."

When a reference is already accurate, just point to it — no need to re-describe it in detail.

Negative control

Positive descriptions work best, but you can suppress subtitles and audio:

"No subtitles."
"No BGM — ambient and action sounds only."
"No audio."

Weak vs. strong

	prompt
weak	`make it move`
strong	`The parked car in the image pulls out and drives down the wet street. 0-3s: headlights flick on, the car eases forward, reflections rippling on the asphalt. 3-6s: it accelerates past the camera, which pans to follow. Low angle, neon reflections, light rain, cinematic night mood. Engine and rain sounds, no music.`

Best Use Cases

Image-to-video animation — Generate motion from a single start image.
Start-and-end-frame guidance — Use image and last_image to guide the beginning and ending of the video.
Cinematic short clips — Create short videos with motion, atmosphere, and synchronized audio.
Social media content — Generate vertical, square, landscape, or ultra-wide video formats.
Creative prototyping — Test scene ideas, motion concepts, and visual directions from a reference image.

Pro Tips

Use a clear start image with the main subject visible.
Use last_image when the final frame or ending direction matters.
Keep prompts focused on visible motion, camera behavior, lighting, and mood.
Use 480p for quick testing, 720p for standard output, 1080p for higher-resolution results, and 4k for maximum-resolution output.
Keep generate_audio enabled when you want the video to include synchronized native audio.
Use a fixed seed when you want more reproducible outputs.
