Synchronize the source
Preserve a high-quality recording and align clocks across the encoder, transcript service, marker interface, and renderer. Store both wall-clock and source-relative timing when possible. Detect restarts and discontinuities instead of shifting later clips silently.
Use monitoring proxies for speed, but render from the best available master. Proxy and master time mapping must be exact.
Combine marker signals
Producers, editors, transcripts, audience signals, scene changes, and event data can all propose candidate moments. Store who or what created each marker, the timestamp, reason, and confidence.
No single signal proves that a moment is publishable. A chat spike can indicate excitement, spam, outrage, or a technical failure.
Review context and render variants
Give every marker handles. Confirm the setup, complete action or thought, reaction, and outcome. Correct names and captions. Approve one editorial master before generating vertical, square, and landscape versions.
Use explicit states so draft candidates never leak into the public feed. Rights and safety checks may differ by event and destination.
Measure each stage
Track capture delay, marker delay, transcript delay, review time, render time, feed publication, and destination processing separately. A single time-to-post number cannot reveal the actual bottleneck.
Record rejection reasons and retry safely. Idempotent jobs, stable GUIDs, and an audit trail make fast corrections possible when a live event changes quickly.
