LTX 2.3 LoRA Foley V2A (Video-to-Audio)
Video-to-audio Foley LoRA: generates synchronized, music-free sound effects from a silent video (also works for text-to-audio Foley prompts). Primary use is muting the source and letting the model produce matching SFX. Gated repo. Place in models/loras/.

Will this run on my GPU?
Minimum: 16GB VRAM.
Recommendation: Strength 0.8–1.0, adjust per clip. Write prompts as physical sound descriptions ending with 'No speech is present. No music is present.' Out of scope: dialogue, music, lip-sync, or a full production mix. Requires the LTX 2.3 audio VAE.

Common issues
ComfyUI doesn't see the file after I downloaded it▼
Make sure the file is in ComfyUI/models/loras/ (not a subfolder). Restart ComfyUI fully — the menu refresh sometimes misses new files. Filename must match exactly: ltx-2.3-22b-lora-foley-v2a-1.0.safetensors.
CUDA out of memory error when loading the model▼
ltx-2.3-22b-lora-foley-v2a-1.0.safetensors needs ~16GB VRAM minimum. If you're hitting OOM: • Enable Sequential Offloading in ComfyUI settings • Lower the resolution (768×512 instead of 1280×704) — both dimensions must be divisible by 32 • Reduce frame count (65 frames instead of 161) — must be 8n+1 • Use a smaller variant — see Related models below.
How do I apply this LoRA in ComfyUI?▼
Load it in a 'LoraLoader' node and connect it after your model loader. Pair this LoRA with the dev base model (not the distilled one) for the right behavior. LoRA strength 1.0 is the trained value — start there.
