Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|

| overlap_frames | INT | 161–200 | Number of frames shared between the two chunks. These frames will be crossfaded. |
| blend_curve | COMBO | ease_in_out | Blend curve shape: linear = straight ramp, ease_in_out = smooth S-curve (3t²-2t³, best for most cases), sigmoid = steep S-curve (snappier transition) |
