LTX 2.3 Workflow Collection, including Wan 2.2 and HuMo refinement

LTX Video 2.3 — Multi-Stage Workflow Collection

A collection of LTX Video 2.3 workflows built for high-end hardware, focused on quality over speed. Designed without get/set nodes, AIO functions aside from text/image combined workflows or subgraphs.

Pipeline Variants

Two-Stage

Draft → Upsample → RefineStandard pipeline

Triple-Stage

Quarter → Half → FullUp to 4x faster · output must be div-by-128

HuMo

Two-stage + motion pass - Audio-driven human motion conditioning

Wan 2.2 LN

Two-stage + refinement pass - lower denoise required than HuMo

Features

• Audio latent retention — first-stage audio latent is carried into refinement rather than re-encoded, preserving timing and texture coherence across passes

• Per-stage sampler & scheduler tuning — each stage uses independently configured samplers and schedulers

• RTX Video Super Resolution output — easily removed if not needed

• Dimension & frame calculator nodes — can be swapped for any input source; note that refinement stages have strict dimensionality requirements

Workflow Types

T2V / I2V toggle · First & Last Frame · Audio I2V · Identity LoRA · Video Continuation

Most types are available across all three pipeline variants.
