LTX A/V Bind Schedule (Koolook)
Decouple big motion from lip-sync in LTX 2.3 by gating the audio->video cross-attention — globally by sigma, or (windowed) only around keyframe transitions so lips stay synced everywhere else. One pass, no re-noise.

Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | LTX 2.3 audio-video model. | |
| early_gain | FLOAT | 0.000–1 | Audio->video strength in the early (high-sigma) steps where big motion resolves. 0 = audio-blind motion; 1 = stock. In windowed mode this is the floor INSIDE the transition bands only. |
| bind_start | FLOAT | 0.550–1 | Denoise progress (0=start,1=end) where audio begins ramping in. |
| bind_end | FLOAT | 0.750–1 | Denoise progress where audio binding reaches full. |
| transition_framesopt | STRING | Comma-separated keyframe transition frames (timeline frames, e.g. '34,63,93'). Empty = global ramp (audio gated everywhere). Set = WINDOWED: audio binds fully everywhere except a band around these frames. | |
| total_framesopt | INT | 00–100000 | Clip length in timeline frames (e.g. 146). Required for windowed mode to map frames -> latent grid. |
| transition_windowopt | INT | 80–100000 | Half-width (timeline frames) of the audio-protected band around each transition. |
