Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| source | IMAGE | Source video or image batch. Can be AI-generated frames, photos, or existing video. | |
| mode | COMBO | first_last | Which frames to extract as LTX guide frames: 'first_last' = first + last frame (standard FLF2V workflow). 'first_only' = just the first frame (simpler I2V). 'last_only' = just the last frame. 'keyframes' = extract at specified indices. 'evenly_spaced' = N frames evenly distributed. |
| keyframe_indices | STRING | 0, -1 | Comma-separated frame indices for 'keyframes' mode. Negative indices count from end. E.g. '0, 40, -1'. |
| num_guides | INT | 32–10 | Number of guide frames for 'evenly_spaced' mode. |
| target_width | INT | 768256–2048 | Output width. LTX 2.3 supports up to 1920. Common: 768, 1024, 1280, 1920. |
| target_height | INT | 512256–2048 | Output height. Must match your LTX empty latent dimensions. |
