LTX 2.3 Max — AI Video Workflow (part 4 of Lab series)
Four inputs. One cinematic video.
Drop in an image, a voice sample, your scene description, and your character's dialog — the workflow takes it from there.
✍️ Script-Driven Dialog Write exactly what you want your character to say in the Dialog Script node. Your words, your story — the workflow handles all the technical execution automatically.
🎬 Scene Description Describe the scene, the mood, the environment. The AI reads this alongside your dialog and builds everything else — no prompt engineering knowledge needed.
🤖 Fully Automatic Prompting Two local AI enhancers run silently in the background. One writes a complete structured video generation prompt from your scene and dialog. The other crafts precise voice delivery direction — pace, tone, emotion, texture — fed directly into the voice engine. You never write a prompt manually.
🎙️ VoX Voice Cloning Provide any short voice sample and VoxCPM2 clones it. Your character speaks your script in that voice, with the AI-generated delivery direction shaping how it's performed — not just what is said, but how.
🔁 Dual Voice Reinforcement The video and audio pipelines are locked together. The video prompt instructs the model on lipsync behavior while the audio direction drives matching emotional delivery through VoX — a unified performance from both sides simultaneously.
⚙️ GGUF & Safetensors Compatible Run whichever model format your hardware prefers — GGUF quantized or full safetensors, both supported out of the box.
