Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| positive | CONDITIONING | — | |
| latent | LATENT | — | |
| frame_idx | INT | 0-9999–9999 | Frame index to anchor the image or the clip first frame at. Negative values are counted from the end of the video. |
| mask_threshold | FLOAT | 0.50-1–1 | Binarize the mask above this value for a hard anchor edge (recommended: kills feathering at the mask border). Set below 0 to keep the mask soft, with gray values giving partial guide strength. |
| vaeopt | VAE | Video VAE, needed when an image is connected. | |
| audio_vaeopt | VAE | Audio VAE, needed when an audio is connected. | |
| imageopt | IMAGE | Image or video frames to anchor. Multi-frame batches are anchored as a clip and cropped down to the model valid clip lengths: 5, 22, 39... (17k + 5) frames. Batches shorter than 5 frames use only the first image. | |
| audioopt | AUDIO | Soundtrack to anchor starting at the same frame index, cropped to the video remaining duration. | |
| maskopt | MASK | Mask over the image guide: 1 keeps the guide anchored, 0 lets the model generate those regions freely. A single-frame mask applies to every frame of a guide clip; a multi-frame mask maps onto the clip by relative time. |
