LivePortrait Models (safetensors)
Mirror of the LivePortrait model weights, converted from .pth to safetensors format for safe, pickle-free loading. Hosted by Æmotion Studio for use with ComfyUI-FFMPEGA.
What is LivePortrait?
LivePortrait is an AI model for portrait animation — it transfers head pose, facial expressions, eye gaze, and lip movements from a driving video onto a source face image. It produces high-quality results in real-time.

⚠️ Conversion Note
Weights were converted from the official .pth checkpoints in KlingTeam/LivePortrait using:
from safetensors.torch import save_file
import torch
# For base models (direct state dict)
sd = torch.load("model.pth", map_location="cpu")
save_file(sd, "model.safetensors")
# For stitching module (nested sub-dicts → flat prefixed keys)
# retarget_shoulder → stitching.*
# retarget_mouth → retarget_lip.*
# retarget_eye → retarget_eye.*
The stitching/retargeting module uses flat prefixed keys in safetensors format. The module. DDP prefix is stripped from all keys.
Usage
These models are automatically downloaded by ComfyUI-FFMPEGA when the Animate Portrait skill is used. No manual setup required if allow_model_downloads is enabled.

Why This Mirror?
- Pickle-free: safetensors format eliminates arbitrary code execution risks
- Supply chain resilience: first-party mirror ensures availability
- Faster loading: safetensors loads faster than pickle-based
