Exploration · Local AI video factory

HLN Machine

HLN Machine explores a local AI video factory. It is not about one generated result, but about splitting generation into a white-box pipeline that can be inspected, rerun, and repaired.

Narrative

Design and engineering judgement

Product frame

Short-video generation looks like media automation, but the real work is workflow design: each intermediate state has to be understandable for the system to keep improving.

Engineering frame

The public Python pipeline coordinates news scripting, speech, A/B-roll, word-level subtitles, branding, and optional YouTube upload. Design notes, module specs, and runbooks make intermediate state and failure location inspectable.

Design frame

This is not a turnkey model or content bundle. It is a public AI engineering lab: the code and architecture are readable, while credentials, model weights, private media, and machine-specific assets remain operator supplied.

System

Components and visibility

Component	Type	Visibility	Role
News story pipeline	Editorial / speech stage	Public snapshot	Fetches source material, builds editorial context, drafts the script, synthesizes speech, and generates subtitle timing.
Video pipeline	ComfyUI media stage	Public snapshot	Selects B-roll references and coordinates ComfyUI image, video, and speech-to-video workflows.
Branding pipeline	Post-production stage	Public snapshot	Renders word-level subtitles and applies brand assets.
Upload pipeline	Distribution stage	Public snapshot	Prepares title, description, and cover, with an optional YouTube Data API upload step.
