Subler is a lightweight macOS application designed for muxing and tagging MP4 files. It allows users to create and embed TX3G and WebVTT subtitle tracks, and add video, audio, and chapter tracks to MP4 containers in a format compatible with Apple devices including iPhone, iPad, Apple TV, and QuickTime. The app is particularly useful for content creators, video editors, and anyone who needs to prepare video files for playback on Apple's ecosystem without complex video re-encoding. It's a specialized but essential tool for anyone working with MP4 files who needs fine-grained control over container metadata and subtitle handling.
