28## Subtitle Behavior
29 
30The Go renderer follows the good behavior from `vertical_srt.py`:
31 
32- Chinese uses word segmentation before line decisions.
33- Display width is used for line splitting: Chinese counts as width 2, other text as width 1.
34- Long Chinese subtitles are split across time into multiple `Dialogue` entries instead of stacked with `\N`.
35- The goal is to keep the screen to one English line plus one Chinese line when possible.

37## Outputs
38 
39- `transferred_vertical_video.mp4`: source converted to portrait format.
40- `vertical_bilingual.mp4`: default final vertical video.
41- `vertical_dubbed.mp4`: final video with `--dubbed`.
42- Final variants are reported through the manifest key `vertical_video`.
