Data Processing Pipeline

Our data processing pipeline is designed to construct a large-scale, high-quality talking-head dataset through systematic preprocessing, filtering, and annotation, ensuring sample uniqueness, temporal consistency, and reliable multi-modal supervision.

Data Preprocessing Stage

Data collection: Aggregates initial content from Web videos and various Open-source videos to build a diverse raw data pool.
Deduplication & Slicing: Employs MD5 hash verification to eliminate redundant content and uses PySceneDetect to divide long videos into coherent clips ranging from 3 to 60+ seconds.
Standardize to 25 FPS: Normalizes all video clips to a uniform frame rate of 25 FPS using FFMPEG to ensure temporal consistency for model training.

Data Filter & Annotation Stage

Face detection & crop: Detects face visibility and crops valid sequences into a centered $512 \times 512$ resolution.
Jump cut detection: Uses optical flow analysis to identify and exclude sequences containing scene discontinuities or abrupt transitions.
Faceless filter: Screens and excludes frames where a detectable face is missing or the head region is improperly framed.
DWpose extraction & hand-filter: Extracts body keypoints and strictly removes clips featuring hand-over-face occlusion to prevent generation artifacts.
Lip-sync: Utilizes the SyncNet model to calculate confidence scores (LSE-C and LSE-D), discarding any samples with poor audio-visual alignment.
Audio feature & attribute labeling: Extracts robust streaming features via Wav2Vec and annotates metadata including language, ethnicity, age, and gender.
