Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|
| desired_duration | FLOAT | 5.00.1–30 | Desired video duration in seconds. |
| fps | INT | 248–60 | Target frame rate. LTX 2.3 default is 24fps. |
| round_mode | COMBO | nearest | How to round to valid 8n+1 frame count. 'round_up' = never shorter than desired. 'round_down' = never longer. 'nearest' = closest match. |
| max_frames | INT | 2579–513 | Maximum frame count. 121=~5s, 257=~10.7s, 513=~21.4s at 24fps. Higher needs more VRAM. |
