# HeyGenVideoTranslateNode - ComfyUI Built-in Node Documentation

> Complete documentation for the HeyGenVideoTranslateNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

Translate a spoken video into another language with voice cloning and lip sync. This node clones the original speaker's voice and re-animates the mouth to match the translated speech, producing a natural-looking result.
