frasave

frasave is a framework and set of practices for saving and archiving frame-based data streams, particularly in multimedia processing, computer vision, and scientific imaging. It aims to balance storage efficiency, fast access, and rich context by treating sequences of frames as first-class persistence units rather than standalone files.

The term frasave is used across open-source projects and academic literature to denote systems that preserve frame sequences with built-in support for metadata, versioning, and retrieval by time, camera, or event.

Core techniques include frame differencing and scene-change detection to avoid storing unchanged content, delta encoding between consecutive frames, traditional and modern compression, and an extensible metadata schema capturing timestamps, sensor data, annotations, and provenance.

A typical frasave architecture comprises a frame input layer, a deduplication and encoding module, an index and metadata store, and a storage backend that may be local, cloud-based, or hybrid. It provides APIs to ingest frames, query frames by time or attribute, and reconstruct streams for playback or analysis.

Common use cases include long-term surveillance and security archives, time-lapse and scientific imaging, sports analytics, visual effects pipelines, and virtual reality workflows where frame-level persistence and rapid access are important.

Critiques center on complexity, potential vendor lock-in, and privacy concerns. The effectiveness of frasave depends on workload characteristics, frame rate, and the ratio of new versus changed content; not every scenario justifies its overhead.
