| fps | FLOAT | 24.00 | — |
| prompt | STRING | Replace the person in <Video 1> with the character in <Picture 1>. Preserve motion, framing and scene. | — |
| window_frames | COMBO | 124 | Maximum generated frames per window; short clips and tails shrink automatically, excluding past history: 107 = 4.46s, 124 = 5.17s. Valid H3 sizes are 17n+5. |
| history_frames | COMBO | 18 | 0 = independent windows; 1 = generated boundary only; 18/35/52... = H3 sliding history. Includes one boundary frame. Must be smaller than window_frames. |
| seed | INT | 9042340–18446744073709550000 | Master seed. Window 1 uses this value; later windows use master + window index. Changing it starts fresh windows and clears per-window overrides. Keep fixed to reroll individual windows. |
