Request body
14 properties · 1 required · 0 $defs| property | type | description | constraints |
|---|---|---|---|
| video_url* | string | The URL of the source video to transform. | |
| seed | integer | Random seed for reproducibility. If None, a random seed is chosen. | nullable |
| enable_safety_checker | boolean | Whether to enable the safety checker. | default: true |
| num_frames | integer | The number of output frames. Output duration is num_frames / frames_per_second. The IC-LoRA control budget caps the resolution x frames volume: roughly 6s at 720p or 15s at 480p; a request above it returns a 422 (lower num_frames, or use 480p). | 9 ≤ n ≤ 481 · default: 121 |
| guidance_scale | number | Classifier-free guidance scale. The default is tuned for fast, high-quality generation. | 1 ≤ n ≤ 20 · default: 1 |
| prompt | string | Optional short description of the video's content/scene. It is woven into the effect's trained caption to sharpen the result; leave empty to apply the effect with a generic description. | default: "" |
| generate_audio | boolean | Whether to include audio in the returned video. When disabled, the final MP4 is returned without an audio track. | default: true |
| resolution | enum | Output resolution (short side), preserving the source aspect ratio. The IC-LoRA control path caps the resolution x frames volume, so resolution trades against duration: 720p allows up to ~6s (sharper), 480p up to ~15s (softer but longer). A request above the b… | 480p | 720p · default: "720p" |
| frames_per_second | number | Frames per second of the generated video. | 1 ≤ n ≤ 60 · default: 24 |
| negative_prompt | string | The negative prompt to steer generation away from. | default: "color distortion, overexposure,… |
| sync_mode | boolean | If True, the media is returned as a data URI inline in the response. Useful for short-lived requests and tests. | default: false |
| video_quality | enum | The quality preset of the generated video. | low | medium | high | maximum · default: "high" |
| num_inference_steps | integer | Number of inference steps. Defaults to 15 and can be increased up to 30. | 8 ≤ n ≤ 30 · default: 15 |
| video_write_mode | enum | The write mode of the generated video. | fast | balanced | small · default: "balanced" |
