Timed TTS narration and video audio mastering
What it does
Synthesize scene narration, fit segments to timing, master the voice track and mux it into supplied video with checksums. A newer script reads scene JSON; defaults still come from an archived product demo.
Core pattern
Scene-based narration synthesis + duration alignment and video muxing
- Input
- See required param_schema fields.
- Output
- See description and operation-specific result.
Key parameters
| Name | Type | Default | Values |
|---|---|---|---|
| voice_id | string | — | — |
| language | string | en | — |
| speed | number | 1 | 0.5–2 |
| sample_rate_hz | integer | 32000 | 8000–192000 |
| bitrate_bps | integer | 128000 | 8000–512000 |
Maturity and limits
Static inspection only; no tests or provider calls executed.
Scripts overwrite chosen output files and assume local tools/layout. Excessive speedup can clip speech because the time-compression factor is capped; verify intelligibility and scene timing.
