LTX-2.3 Multishot Lite - chained talking shots, core nodes only — v2.0

What v2 does instead. The last ~3 seconds of shot 1 — video and audio — are encoded as latent context, and the model generates forward from an ongoing utterance. This is the pattern community extend workflows and Lightricks' own hosted /extend endpoint use. Consequences:

• The voice carries over by construction. The chained shot needs no reference-audio node at all.
• Identity holds through the join, and the join is a continuous take rather than a cut.
• Measured on the shipped demo config, chained-shot audio/mouth correlation went from ~0.1–0.4 (wildly unstable) to 0.64 — and the second shot now syncs better than the first.

Also in v2.0

• Guide strength is 0.7 everywhere (the official value; 1.0 silently disables the guide's attention mask).
• Every length-dependent value now follows the single length primitive automatically — negative indexing for the last frame, clamped trims — so changing duration is a one-widget edit instead of seven. (In v1 the audio latent did not follow length, so anyone who changed duration silently desynced audio from video.)
• Notes inside the graph rewritten to match the new architecture.

One dependency change. The extension node (LTXVAudioVideoMask) ships in ComfyUI-KJNodes. Everything else is still core ComfyUI. v1's "no custom nodes at all" claim is retired — if you work with LTX you almost certainly have KJNodes already, and it buys working multishot.

Requirements unchanged otherwise: a distilled LTX-2.x checkpoint, the LTX-2.3 VAEs and Gemma text encoder, and the ID-LoRA for reference-voice mode.

Note: the workflow ships at cfg 1, which makes negative prompts inert on distilled models. If you need a negative to take effect — for example to suppress burned-in subtitles — raise it to about 1.3.
