InfiniteTalk vs SyncTalk
Audio-driven talking video projects compared
InfiniteTalk and SyncTalk both generate speech-synchronized video from audio. InfiniteTalk supports animating a still image or dubbing an existing video, including long-form generation, while SyncTalk focuses on subject-specific talking-head synthesis through a research pipeline.
InfiniteTalk: Generate Audio-Driven Talking Videos
InfiniteTalk generates talking videos from audio and an image or existing video, synchronizing speech with facial expressions and body movement. It is aimed at creators and developers who need dubbed or audio-driven video, including long-form generation.
SyncTalk: Generate Synchronized Talking-Head Videos
SyncTalk is a CVPR 2024 system for generating talking-head videos from a person’s footage and audio. It targets synchronized lip movement, facial expression, and head pose, with workflows for training on a subject or running inference with provided models.
