KrillinAI Render Vertical

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

Bilingual Short-Subtitle Video

(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" render-vertical \
  --workdir "$WORKDIR" \
  --video "$WORKDIR/origin_video.mp4" \
  --subtitle "$WORKDIR/short_origin_mixed_srt.srt" \
  --major-title "今日话题" \
  --minor-title "AI Video")

Dubbed Vertical Video

(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" render-vertical \
  --workdir "$WORKDIR" \
  --video "$WORKDIR/video_with_tts.mp4" \
  --subtitle "$WORKDIR/target_language_srt.srt" \
  --dubbed \
  --major-title "今日话题" \
  --minor-title "AI Video")

Subtitle Behavior

The Go renderer follows the good behavior from vertical_srt.py:

Chinese uses word segmentation before line decisions.
Display width is used for line splitting: Chinese counts as width 2, other text as width 1.
Long Chinese subtitles are split across time into multiple Dialogue entries instead of stacked with \N.
The goal is to keep the screen to one English line plus one Chinese line when possible.

Outputs

transferred_vertical_video.mp4: source converted to portrait format.
vertical_bilingual.mp4: default final vertical video.
vertical_dubbed.mp4: final video with --dubbed.
Final variants are reported through the manifest key vertical_video.

Verification

Use text and visual checks:

rg -n -F '\\N' "$WORKDIR/formatted_vertical_bilingual.ass"
ffmpeg -y -ss 00:00:01 -i "$WORKDIR/vertical_bilingual.mp4" \
  -frames:v 1 "$WORKDIR/vertical_preview_%03d.jpg"

Also require terminal JSON with "ok": true, valid video/audio streams, readable subtitles, and non-garbled titles.

discernment-nudge

After you give a substantive answer or draft that the user may act on — advice or recommendations, drafted artifacts such as goals, plans, pitches, proposals, or emails, estimates or projections, analysis or interpretation of data, factual claims they may rely on, or a multi-step argument — invoke this skill BEFORE finalizing your reply and then, if it applies, append 2-3 short follow-up questions, each tied to something specific in what you just produced, that help the user check key facts, probe the reasoning or assumptions, and notice missing context. Do this at most once per conversation. Skip it when the user asked a trivial how-to or simple lookup, wants a purely educational explanation, asked you only to format, convert, or assemble a file from content they provided, is writing code they will run, is doing creative writing or casual chat, or already asked you to double-check, cite, or review — the skill file explains these boundaries and the exact output format.
