LTX 2.3 Video Reasoning LoRA — Make AI Motion Actually Believable

ComfyUI tutorial focused on getting more believable motion out of LTX 2.3 using the video reasoning LoRA — practical tips and side-by-side comparisons.

📹 Video Tutorial

Editor's Note: Tutorial focused on motion quality. Useful follow-up to the IC-LoRA videos once you've got the basics working. Compares outputs with and without the reasoning LoRA and discusses prompt structure for natural motion.

Why this matters

LTX 2.3 distilled is fast (8 steps), but stiff or jittery motion is the most common quality complaint. This video focuses on:

  • Prompt patterns that produce more natural motion
  • How the video reasoning LoRA changes the output
  • When to use distilled vs dev for motion quality
  • CFG and step count tradeoffs (NVIDIA recommends 20–30 steps, CFG 3.0–3.5 for iteration — see NVIDIA's LTX-2.3 guide)
