Could you build this?
No Running an agentic harness that performs multi-axis scoring, subject tracking, transcription, and video rendering entirely on-device on Apple Silicon requires specialized native video DSP and local ML engineering.
What it would actually take: The application requires a native macOS architecture leveraging Metal, CoreML, Vision framework, and AVFoundation. Video processing pipelines require custom frame-by-frame subject tracking algorithms, local Whisper inference for transcription, and multi-modal local LLMs for moment scoring and highlight selection without latency. High-level expertise in macOS media frameworks, local neural engine optimization, and computer vision tracking is required.
