This repository is a comprehensive, community-authored tutorial for video encoding and VapourSynth preprocessing, maintained by VCB-Studio. It is primarily documentation with executable example scripts (.vpy), covering everything from video format fundamentals to advanced mask generation and expression-based pixel manipulation. The 'Basics' section builds foundational knowledge (e.g., video properties, common artifacts, encoding tools), while the 'Advanced' section dives into VapourSynth internals like the Expr filter and mask creation. Although not a standalone application, the scripts are production-oriented and carefully crafted to illustrate best practices in Blu-ray ripping and quality enhancement. The repository is actively maintained with a responsive issue tracker, and its content reflects current industry techniques.
MetaSeg is a Python library that packages Facebook's Segment Anything Model (SAM) into an easy-to-use interface for automatic and manual image/video segmentation. It provides high-level predictors (SegAutoMaskPredictor, SegManualMaskPredictor) that handle model loading, inference, and output visualization. The library integrates with SAHI for sliced inference and FalAI for cloud GPU execution, and includes a Gradio web application. The codebase is primarily a thin orchestration layer over the official SAM implementation, with additional utility functions for data loading, video processing, and model download. It is designed for developers who want to quickly apply SAM without deep model internals.
