SRT 至 VTT
轻松将SRT文件转换为VTT格式
字幕在让更多观众观看视频方面发挥着重要作用,并且有许多不同的格式可用于为视频添加字幕。最广泛使用的两种字幕格式是SRT(SubRip 字幕)和VTT(WebVTT)。虽然这两种格式的用途相同,但它们的结构不同,并且在不同的环境中使用。SRT通常由各种视频播放器使用,而VTT则更受基于 Web 的应用程序青睐。
在本文中,我们将指导您完成将SRT 转换为 VTT的过程,以确保您的字幕文件与使用 WebVTT 的网络视频播放器和平台兼容。
什么是SRT文件?
SRT文件(SubRip 字幕)是视频文件最流行的字幕格式之一。它简单、易于创建,并且几乎所有视频播放器都支持它。SRT 文件的结构由字幕序列组成,其中包括:
- 字幕编号
- 表示字幕出现和消失时间的时间戳
- 字幕文本
以下是 SRT 文件的示例:
在 SRT 格式中,时间戳使用逗号将秒和毫秒分隔。
什么是VTT文件?
VTT文件(WebVTT) 是一种文本文件格式,用于显示 HTML5 视频中的字幕、副标题和其他定时文本轨道。WebVTT 是网络视频的标准格式,广泛用于基于 HTML5 的视频播放器和 YouTube 等流媒体平台。
A WebVTT file follows a similar structure to an SRT file, but there are a few key differences. The timestamps in WebVTT use periods to separate the seconds from the milliseconds (instead of commas), and there is a "WEBVTT" header at the beginning of the file.
Here is an example of a WebVTT file:
Why Convert SRT to VTT?
You might need to convert an SRT file to VTT for a few reasons:
-
Web Compatibility: If you're uploading a video to a website or a platform that uses HTML5 video players (such as YouTube or Vimeo), you may need to use WebVTT (VTT) subtitles instead of SubRip (SRT). Many web-based video players rely on the VTT format for displaying captions and subtitles.
-
Web Video Players: Some video players that are embedded into web applications require VTT files to function properly. If your subtitle file is in SRT format, converting it to VTT will make it compatible with these players.
-
Streaming Platforms: Streaming platforms like Twitch and other online video services often use WebVTT for subtitles. If you plan to stream videos on these platforms, you may need to convert your subtitles to WebVTT format.
-
Improved Syntax: WebVTT files allow for additional features like styling (e.g., font size, color) and positioning that are not available in SRT files. If you're working with such features, converting SRT to VTT can be a good idea.
