Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| enabled | BOOLEAN | true | Turn FreeLong on or off. Useful for comparing results with and without. |
| blend_strength | FLOAT | 0.80–1 | How strongly FreeLong affects the video. Higher = more consistent motion but slightly softer. Lower = sharper but may drift. 0.8 is optimal for most cases. |
| low_freq_ratio | FLOAT | 0.800–1 | Balance between motion consistency and fine detail. Higher = smoother, more consistent motion. Lower = more dynamic but may drift. 0.8 is a good balance. |
| local_window_frames | INT | 339–241 | How many video frames the detail-preservation looks at. Smaller = sharper details but may cause morphing. Larger = smoother transitions. 33 works well for 81-frame videos. For longer videos, try ~40% of total frames. |
| blend_start_block | INT | 0-1–40 | Advanced: Which model layer to start applying FreeLong. 0 = from the beginning. Most users should leave this at 0. |
| blend_end_block | INT | -1-1–40 | Advanced: Which model layer to stop applying FreeLong. -1 = apply to all layers. Most users should leave this at -1. |
