Overview
Requires Python 3.11+. `to-captions-pipeline.py` needs ffmpeg and faster-whisper (via `uv run`). Run scripts via `uv run`.
Recipes
Copy-paste command sequences agents can run via uv run. Replace <skill_directory> with the absolute path of this skill (the folder that contains SKILL.md) — do not run scripts/… relative to cwd.
Check compliance rules
uv run <skill_directory>/scripts/rules.pyValidate an SRT file
uv run <skill_directory>/scripts/validate.py --input captions.srtNormalize whitespace and wrap long lines
uv run <skill_directory>/scripts/format.py --input captions.srtExport for broadcast (SCC / CEA-608)
uv run <skill_directory>/scripts/to-scc.py --input captions.srt --output deliverable.sccExport SMPTE-TT / TTML
uv run <skill_directory>/scripts/to-smpte-tt.py --input captions.srt --output captions.xmlFlag cues that may hit lower-thirds
uv run <skill_directory>/scripts/apply-busy-zones.py --input captions.srtSpeech → SRT (full pipeline)
uv run <skill_directory>/scripts/to-captions-pipeline.py --input clip.mp4 --model tinyOperations
Each script returns structured JSON — see the script contract.
