## Useful for

- Cut an interview by timecodes and fit it to 60 seconds for Reels
- Add karaoke captions and a vertical crop for TikTok
- Remove silence and normalize loudness to -14 LUFS

## Why it’s here

- Star-counter measurements on 2026-10-29 (UTC), 00:03–04:59: 3519 → 3607 stars (+88). This is the change over that interval.
- Estimated end-of-day forecast: about +456 stars, using observed gains and the previous day.
- Over the last two days the pace is 4.6× that of the previous week and a half.
- The repository is 56 days old and already has 3,607 stars.
- About 41 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 289
- Issues and pull requests: 367
- Watchers: 6
- Average over the last week: 289 per day
- Usual pace: 19 per day
- Stars in the last hour (measured): 17

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
