LongCat-Video-Avatar digital human text-to-video long video

This workflow is built to generate long, audio-driven videos of a digital avatar using the LongCat-Avatar model. Its core function is to synchronize a character's lip movements and facial expressions with a provided audio track. The system processes the video in sequential, overlapping chunks, allowing it to maintain consistency and create extended, seamless animations from a single reference image. In practice, the workflow takes a reference image and an audio file as input. It uses an audio processing pipeline to create motion embeddings that drive the avatar's performance. The "long video" capability is handled by an iterative process where the end of one generated segment is used as the starting point for the next, ensuring smooth transitions and making it effective for producing continuous, long-form talking avatar content. 🎥 YouTube Video Tutorial Want to know what this workflow actually does and how to start fast?
