## Description

VideoCaptioner is an automated tool designed to generate and embed time-synchronized subtitles into video files. By leveraging speech recognition models, the software converts spoken audio into text and calculates precise timestamps to ensure captions align with the original media.

The project operates as a local-first inference pipeline, performing all transcription tasks on the host machine to maintain data privacy. It utilizes a transformer-based neural network for speech recognition and integrates a multimedia framework to handle the technical aspects of video processing and subtitle stream multiplexing.

Beyond automated transcription, the tool provides capabilities for hardcoded subtitle embedding and the permanent integration of text tracks into video containers. This functionality ensures that generated captions remain visible across various media players and devices, supporting accessibility for hearing-impaired viewers.
