为什么要对WebVTT提示使用多个连字符？

Question

我在看https://developer.mozilla.org/en-US/docs/Web/API/WebVTT_API。

相关示例是这样：

WEBVTT - This file has cues.

14
00:01:14.815 --> 00:01:18.114
- What?
- Where are we now?

15
00:01:18.171 --> 00:01:20.991
- This is big bat country.

16
00:01:21.058 --> 00:01:23.868
- [ Bats Screeching ]
- They won't get in your hair. They're after the bugs.

我不明白为什么我会用一个连字符They won't get in your hair. They're after the bugs而不是这样做：

- [ Bats Screeching ]
- They won't get in your hair.
- They're after the bugs.

最初的意思是它将在同一时间范围内分成两张标题卡，而不是三张吗？如果是这样，为什么不将其分解为更多的提示，而不是包含更多连字符的提示？还是要在标题卡中同时显示多行？

Answer 1

抓住玩家的每个破折号是换行符：

00:01.000 --> 00:10.000
- It will do something.
- It will do another thing.

因此，由工程师决定什么是合适的句子长度以及是否需要多行。
