# Speech-free & music-free source clips — a random sample of 12

Drawn at random (seed 20260809) from the **8,191** clips that survived a two-stage audio filter over
**101,503** source videos from InsAVE-80K and JAVEdit-100k:

1. **No speech** — FireRedVAD over every clip, then FireRedASR2-AED transcription on every VAD
   positive; a clip is kept only if no real words were transcribed.
2. **No music** — no music-related AudioSet tag (74 of them: Music, Background music, Musical
   instrument, Theme music, Guitar, Piano…) anywhere in the top five.

These are the **inputs** to the object-removal pipeline, not its outputs.

## Sampled, not cherry-picked

3 of the 12 carry `Speech` as their top AudioSet tag despite VAD and ASR both clearing them. That is
the known model disagreement: FireRedASR2 covers Chinese and English, so speech in another language
transcribes empty and slips through. Those are flagged in the manifest as `speech_disagreement`; the
stricter variant (`kept_no_speech_strict.csv`, 6,983 clips) drops them.
