Krillinai Subtitle is an Agent Skill for documents published in the krillinai/KrillinAI repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when generating subtitles with KrillinAI CLI from a YouTube link, Bilibili/local video, or existing media, including platform caption download, Whisper fallback, translation, bilingual SRT, and short vertical subtitle output.

KrillinAI Subtitle

Use this skill for the subtitle stage.

Command

./build/krillinai-cli subtitle "<input>" \
  --origin-lang en \
  --target-lang zh_cn \
  --workdir tasks/demo \
  --caption-source any

Build the CLI first if needed:

go build -o build/krillinai-cli ./cmd/cli

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
`--bilingual-top=true`	Put target language on top in bilingual SRT
`--dry-run`	Validate without downloads or AI calls

Outputs

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
origin_audio.mp3

Verification

Confirm stdout JSON has "ok": true.
Confirm krillinai_manifest.json exists under --workdir.
Spot-check bilingual_srt.srt ordering and short_origin_mixed_srt.srt readability.
