KrillinAI Subtitle

Use this skill for the subtitle stage. Read skills/krillinai-cli/references/cli-contract.md first for binary location, execution working directory, configuration, and JSON behavior.

Command

(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" subtitle "<input>" \
  --origin-lang en \
  --target-lang zh_cn \
  --workdir "$WORKDIR" \
  --caption-source any \
  --prepare-video)

Inputs

YouTube URL: prefer --caption-source any; platform captions are used first, then Whisper fallback.
Local file: use local:/abs/path/video.mp4 or a path accepted by the CLI.
Bilibili or other yt-dlp supported links: use when media download works; platform caption behavior may differ, so expect transcription fallback.

Important Flags

Flag	Use
`--origin-lang`	Source language, such as `en`, `zh`, `ja`
`--target-lang`	Target language, such as `zh_cn`
`--workdir`	Dedicated task directory
`--caption-source any`	Prefer platform captions, fallback to transcription
`--caption-source whisper`	Force transcription
`--prepare-video`	Require the original video for later render stages
`--bilingual-top=true`	Put target language on top in bilingual SRT
`--subtitle-style-file`	Merge a JSON subtitle-style override
`--dry-run`	Validate without downloads or AI calls

Outputs

After a real run, read paths from krillinai_manifest.json. Main files:

origin_language_srt.srt
target_language_srt.srt
bilingual_srt.srt
short_origin_mixed_srt.srt
origin_video.mp4 when media preparation produced or required video
origin_audio.mp3 when transcription preparation produced audio

subtitle --dry-run validates command shape but does not write a manifest or output files.

Verification

Require terminal JSON with "ok": true.
Confirm krillinai_manifest.json exists under --workdir.
Spot-check bilingual_srt.srt ordering and short_origin_mixed_srt.srt readability.
When --prepare-video was requested, require a non-empty origin_video output.
