LTX 2.3 Director in ComfyUI | Timeline AI Filmmaking Workflow

Turn prompts into full cinematic videos with timeline control.

Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning - you still choose inputs, prompts, and settings.

Why RunComfy first
- Fewer missing-node surprises - run the graph in a managed environment before you mirror it locally.
- Quick GPU tryout - useful if your local VRAM or install time is the bottleneck.
- Matches the published JSON - the zip follows the same runnable workflow you can open on RunComfy.

When downloading for local ComfyUI makes sense - you want full control over models on disk, batch scripting, or offline runs.

How to use (local ComfyUI)
1. Load inputs (images/video/audio) in the marked loader nodes.
2. Set prompts, resolution, and seeds; start with a short test run.
3. Export from the Save / Write nodes shown in the graph.

Expectations - First run may pull large weights; cloud runs may require a free RunComfy account.

Overview

This workflow lets you build cinematic stories with timeline precision. You can arrange images, camera moves, and audio across scenes like in professional editors. It helps create polished, story-driven videos with AI assistance. Manage multiple scenes, prompts, and transitions in one place. Ideal for storytellers, filmmakers, and anyone crafting structured video narratives efficiently.

Important nodes:

Key nodes in Comfyui LTX 2.3 Director workflow

• LTXDirector (#46). The heart of LTX 2.3 Director. It accepts a global prompt, a timeline of shot segments, and optional per‑shot local prompts, then outputs structured guidance plus synchronized AV latents. Tune the balance between global and local prompts to control how tightly each shot follows its own description. For cut‑driven edits, keep segment definitions clean; for fluid transitions, allow overlap and consistent style language.

• LTXDirectorGuide (#8). Turns the director’s cues into actionable guides for Stage #1. Adjust its scale and resampling method to trade speed for fidelity during the preview pass. If scenes look too coarse, increase its influence; if over‑constrained, reduce it so the sampler can breathe.

• LTXDirectorGuide (#58). A second, higher‑fidelity guide for Stage #2. Use it to re‑assert framing, camera intent, and style after upscaling. Balance this node with the upscaler: stronger guidance locks composition, while a lighter touch lets the upscaler emphasize detail and micro‑texture.

• LTXVCropGuides (#55). Normalizes composition and enforces aspect rules before upscaling. Use it to stabilize horizons, headroom, and center of interest across cuts. If a character drifts frame to frame, strengthen these crop guides before resampling.

• LTXVLatentUpsampler (#52). Applies the LTX‑2.3 Spatial Upscaler x2 to the latent. This is the main lever for recovering crisp detail from the Stage #1 preview. Ensure the chosen upscaler model matches your VAE pair to avoid mismatch artifacts.

• CFGGuider (#9, #49). Controls prompt adherence during sampling. Lower values typically yield smoother motion and more natural transitions; higher values enforce textual precision. If faces or props drift, raise guidance slightly; if motion looks stiff, ease it.
