Inputs (18)
| Name | Type | Default | Description |
|---|---|---|---|
| source_images | IMAGE | The source images to extend (from previous generation) | |
| overlap_frames | INT | 101–256 | Number of overlapping frames between batches |
| overlap_side | COMBO | source | Which side to take overlap frames from |
| overlap_mode | COMBO | linear_blend | Blending method for overlapping frames |
| enable_math | BOOLEAN | true | Enable math calculations for frame adjustments |
| math_operation | COMBO | a-b | Math operation to perform on overlap value |
| safe_mode | COMBO | none | Compatibility: mimic the original workflow behavior (start_images extracted as images[-overlap_frames:-1]) |
| start_frames_rule | COMBO | none | Optional: force start_images frame count to LTX rule (1 + 8*x) for VideoVAE encode |
| color_match_mode | COMBO | none | Optional: match color/exposure of new_images to the tail of source_images before merging |
| color_match_strength | FLOAT | 1.000–1 | 0=no effect, 1=full match (only used if color_match_mode != none) |
| color_reference_window | INT | 81–256 | How many frames from the tail/head to use for stats matching |
| seam_search_mode | COMBO | none | Optional: search inside new_images for a better seam start (reduces rewind/odd restarts) |
| k_search | INT | 00–64 | How many candidate offsets to test (0 disables). Used only if seam_search_mode=best_of_k |
| metric_weight_color | FLOAT | 1.00–5 | Weight for color/luma continuity metric |
| metric_weight_edges | FLOAT | 0.50–5 | Weight for edge continuity metric |
| preset | COMBO | custom | Preset that auto-configures overlap/blend/seam search options (and updates widgets live). Choose 'custom' to keep manual settings. |
| new_imagesopt | IMAGE | The newly generated images to extend with | |
| math_value_bopt | INT | 10–256 | Second operand for math operations (b) |
