About

LivePortrait is an AI digital-actor and lip-sync tool. Open-source portrait animation: transfer expression and pose from a driving video.

Our take — LivePortrait for short drama

LivePortrait, from Kuaishou's research arm, transfers expression and pose from a driving video onto any portrait — humans, and even cats and dogs. For short drama it's one of the most useful free primitives we track: one performer can puppet a whole cast of AI-generated faces, which is how consistent characters get acted rather than merely lip-synced.

The tradeoff versus hosted tools like Hedra or Sync is operational: you self-host on an NVIDIA GPU, wire it into ComfyUI, and own the pipeline — no per-second fees, no platform gatekeeping, but also no support when a frame glitches. Our read: ideal for technical studios building repeatable character pipelines; wrong for solo writers who need output today.

Best for

Technical studios self-hosting a repeatable expression-transfer pipeline for consistent AI characters.

Watch out

Research code, not a product: needs an NVIDIA GPU, setup time, and tolerance for edge-case artifacts.

  • Expression and pose transfer from video
  • Stitching and retargeting control
  • Video-to-video editing mode
  • Broad ComfyUI ecosystem
