常见使用场景

机器翻译纯文本已经很成熟,难点在于字幕的格式:SRT 和 VTT 有固定的段落结构、序号和精确到毫秒的时间戳,翻译后必须原样保留。直接复制到翻译网站,格式往往会被打乱。

本工具把文件拆成只含文本的片段,按顺序逐段翻译,再用原来的时间戳重新组装成 SRT——时间轴与视频完全同步,只有字幕文字变了。做字幕组翻译、YouTube 多语言上传、无障碍字幕时,这能省下大量手动对轴的时间。

使用技巧

英语译成西班牙语、法语、德语、葡萄牙语等欧洲语言质量很高;译成中文、日语、韩语也不错,但俚语和习语最好人工过一遍。医学、法律等专业内容,机器翻译适合作初稿,发布前请专业人士审校。

人名、品牌名、专业术语很重要时,发布前在译文里批量查找替换一遍。保留原始 SRT——发现问题时对照原文改起来最快。VTT 文件会被自动识别并转成标准 SRT,SRT 不支持的位置、对齐等 VTT 设置会被去掉。

常见问题

这个字幕翻译工具真的免费吗?

我的字幕文件会上传到服务器吗?

文件在你的浏览器里读取,只有字幕文本会发送给翻译服务,不会被保存,工具也不记录内容。

支持哪些格式?

SRT(.srt)和 WebVTT(.vtt),也可以直接粘贴字幕文本。

支持哪些语言?

借助 Google 翻译支持 100 多种语言,包括中文、日语、韩语、西班牙语、法语、德语、阿拉伯语、印地语等。

翻译需要多久?

500 段以内的字幕文件大多 30 秒内完成,更长的文件可能需要一两分钟。
