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.
