Built in ComfyUI specifically for NSFW / adult video generation. Takes any input clip, interpolates frames for smooth playback, generates ultra-realistic or exaggerated lewd sound effects via dual MMAudio branches (SFW for clean ambience &amp; impacts, NSFW for gagging, slurping, sticky thrusts, heavy breathing), overlays expressive TTS dialogue/moans from Qwen3-TTS (voice cloning from reference or pure text-based design), and even lets you blend in the original video audio for that hybrid real-AI punch. No more manual editing in Audacity or Resolve - queue it up, tweak volumes/seeds/prompts, and export MP4s with timestamped filenames ready for your stash. Perfect for adult ASMR, scene enhancement, erotic animation, or just experimenting with er... sound design. ### Key Features - **Dual MMAudio Branches** - SFW (vanilla model for natural sounds) + NSFW (gold-tuned for explicit SFX). Mute groups to switch modes without errors. - **Qwen TTS Power** - Separate groups for Voice Design (text-based fantasy voices like “sultry breathy moans”) or Voice Cloning (from ref audio + transcript). Auto-trims to match video length. - **Geeky AudioMixer Core** - 4-track mixing with per-layer volume, start offsets, fades, master normalize/compress/limit. Crank original video audio or mute it via Primitive toggle. - **RIFE FPS Converter** - Auto-handles any input FPS → targets 25 fps (or your choice) for perfect MMAudio sync. - **Shared Seed Control** - One Primitive seeds MMAudio + TTS for consistent randomness across layers. ### How to Use 1. Drop your video into VHS_LoadVideo. 2. Tweak prompts: - MMAudio SFW and/or NSFW - TTS (Voice Design or Cloning) 3. Mute groups for modes: Bypass SFW/NSFW/TTS as needed 4. Adjust mixer volumes: audio_1 = main voice/TTS, optionals = SFX/original. 5. Queue — outputs MP4 with embedded audio. ### Pro Tip – Pair with LTX2 (Latent Text-to-Video) LTX2 is blowing up for realistic lip sync and facial animation right now - but it lacks rich, layered lewd audio (moans, wet SFX, heavy breathing, gagging). Easy hybrid: 1. Generate your talking-head / character video in LTX2. 2. Load the LTX2 MP4 into this workflow's VHS_LoadVideo node. 3. Run as usual - MMAudio adds filthy SFX layers, Qwen TTS overlays breathy moans/dialogue. 4. Mix with LTX2 original audio (or mute it) - final export has perfect visual sync + dirty sound design. LTX2 does lips &amp; face, this workflow does the lewd audio. Instant upgrade. 🔥 ### Low-VRAM Tips (12GB seems to be a minimum): - Use **Qwen3-TTS 0.6B** instead of 1.7B → saves ~3–4 GB with only minor quality drop on short clips. - Set **unload_model_after_generate = true** in TTS nodes → unloads TTS immediately after generation. - Reduce **RIFE batch_size** to 4 or 2 → lowers peak during interpolation. - For tighter VRAM: mute RIFE group if not needed, or add **Unload All Models** node (ComfyUI-Unload-Model extension) after TTS before MMAudio. - Peak usage drops to ~9-11 GB with these tweaks - 8 GB cards are very tight (possible only with extreme cuts like no RIFE + tiny clips). ### Requirements (Custom Nodes via ComfyUI Manager) - comfyui-mmaudio (kijai/ComfyUI-MMAudio) - qwen3-tts-comfyui (flybirdxx/ComfyUI-Qwen-TTS or similar fork) - ComfyUI_Geeky_AudioMixer (GeekyGhost/ComfyUI_Geeky_AudioMixer) - ComfyUI-VideoHelperSuite (Kosinkadink/ComfyUI-VideoHelperSuite) - rgthree-comfy (rgthree/rgthree-comfy) - ComfyUI-VFI (Fannovel16/ComfyUI-Frame-Interpolation) for RIFE ### Models Needed (auto-download or manual from Hugging Face) - MMAudio SFW: kijai/mmaudio_large_44k_v2_fp16.safetensors - MMAudio NSFW: phazei/mmaudio_large_44k_nsfw_gold_8.5k_final_fp16.safetensors - Qwen3-TTS: Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice (or 0.6B for lower VRAM)</h3>
