ComfyUI-QwenVL-Mod — Enhanced Vision-Language with LTX 2.3 Version 2.3.1 (2026/08/25) — 🎬 LTX 2.3 Native Video+Audio + 10Eros Uncensored + Qwen3.5 Auto-Prompting

⚠️ Requirements — Read First!

GPU & VRAM

• 🟢 Recommended — RTX 5090 / 4090 (24 GB+) → FP8 text encoder + checkpoint FP8 → Fast, best quality

• 🟡 Enthusiast — RTX 3090 / 4080 (16-24 GB) → offload text encoder / VAE → Slower, good quality

• 🟠 Budget — RTX 4060 Ti 16 GB → aggressive offload + lower resolution → Experimental, slow

12 GB GPUs: Not recommended for LTX 2.3 with the full 10Eros setup. The text encoder alone is ~12.8 GB FP8.

Software

• ComfyUI: v0.32.0+ (required for LTX 2.3 native audio and Sage Attention flags)

• Python: 3.10+

• CUDA: 13.0 recommended

• Storage: 100 GB+ SSD (models ~40 GB + outputs)

Qwen3-VL Prompt Enhancer

• GGUF: Q4_K_S (~4.8 GB) or Q5_K_S (~5.5 GB) for 8B model

• HF: Qwen3-VL-8B-Heretic-Stable (~16 GB) or Qwen3-VL-4B (~8 GB)

🌟 What is ComfyUI-QwenVL-Mod?

A powerful enhanced vision-language node for ComfyUI that combines Qwen3-VL models with LTX 2.3 video generation workflows. Features multilingual support, visual style detection, native synchronized audio, and NSFW capabilities for professional AI content creation.

Think: *"Your all-in-one solution for intelligent prompt enhancement and uncensored video+audio generation with LTX 2.3!"

🎬 Key Features

🚀 LTX 2.3 Native Video+Audio Generation

• I2VA (Image-to-Video+Audio): Animate a first-frame image with synchronized audio

• FL2VA (First-Last-Frame): Generate the transition between two keyframes with audio — Qwen3-VL sees both frames

LTX 2.3 produces video and audio in the same forward pass: no separate MMAudio or audio-VAE stitching is required.

🧠 Qwen3.5 Auto-Prompting

• Multilingual: Write your prompt in any language — Qwen3-VL translates and converts it

• Auto-format: Generates optimized LTX 2.3 prompt structure

• Multi-reference: Qwen3-VL sees all connected images via image + image2 inputs

• Visual style detection: 12+ artistic styles (photorealistic, cinematic, anime, 3D CG, claymation, vintage film, watercolor, fantasy, etc.)

• Smart caching: Performance optimization with Fixed Seed Mode

• GGUF backend: Efficient local model inference with quantization support

• Qwen3.5 support: Thinking mode disabled via /no_think for fast prompt generation

🔊 Native Synchronized Audio

• No separate audio node needed — LTX 2.3 generates video and audio jointly

• Voice, sound effects, ambience and music modeled together

• Describe sounds and dialogue in your prompt and the model generates them natively

🎨 NSFW Support

• Comprehensive content generation without restrictions

• Dedicated NSFW presets tuned for LTX 2.3 I2V and FL2V

• Natural progression, consistent characters, explicit diegetic soundscape

📦 What's Included — 2 Workflows

1. 🖼️ I2VA — LTX23-I2VA-Qwen3.5.json — text + first-frame image (image) — Image-to-video+audio. 10Eros v1.5 + DMD hybrid v2 LoRA, dual-stage with spatial upscaler.

2. 🔄 FL2VA — LTX23-FL2VA-Qwen3.5.json — text + first-frame (image) + last-frame (image2) — First-Last-Frame to video with audio. Qwen3-VL sees both frames and describes the transition. Includes TensorRT upscale + RIFE frame interpolation for high-resolution output.

Both workflows include TensorRT upscaling (RealESRGAN x4) and RIFE frame interpolation.

🖼️ Multi-Reference Input (image2)

The QwenVL-Mod node has two image inputs:

• I2VA: image = first frame

• FL2VA: image = first frame, image2 = last frame, frame_count = 1

Qwen3-VL sees all connected images as individual images (not as a video sequence), enabling proper multi-reference analysis for FL2VA.

🎯 QwenVL-Mod NSFW Presets

The workflows include built-in NSFW presets for the Qwen3-VL prompt enhancer:

• 🎬 LTX 2.3 NSFW I2V — Image-to-video with mandatory audio instructions

• 🔄 LTX 2.3 NSFW FL2V — First-last-frame transition with audio instructions

What the presets produce

• 🎬 I2VA: Rich scene description, camera motion, subject action, explicit diegetic soundscape, non-diegetic music flag

• 🔄 FL2VA: Describes the transition path between first and last frames (not the scene — images fix the scene). Favors single continuous shot.

• All presets: smooth, continuous camera motion (no abrupt or stepped changes), explicit audio notes

SFW presets are also available. Edit the preset dropdown in the QwenVL node to switch.
