## Overview

Clipp is a private, local Android video editor. Its principal workflow is selecting media, editing a project with timeline content and effects, then rendering and exporting an MP4; project management and templates provide adjacent workflows. The README confirms these capabilities, while the available source excerpts contain no runtime implementation, so links between individual modules are limited to the documented workflow and are not presented as verified calls.
