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.
