ass2srt.vbs(ass/ssa批量转换srt的脚本)

(编辑：jimmy 日期: 2024/12/26 浏览：3 次 )

iPad中的OPlayer只支持srt格式的字幕，而动画一般使用的是ass/ssa格式的字幕，所以需要将ass/ssa批量转换srt。

Google了一下，在《ass2srt[ass/ssa批量转换srt]》中找到一个ass2srt.wsf脚本，内容如下：

<job id="ass2srt">
  <script language="JScript">
  cInput="unicode";  // You can find them from:
  cOutput="utf-8";  // HKEY_CLASSES_ROOT\MIME\Database\Charset
  function rrr(){
    re = /Dialogue: [^,.]*[0-9]*,([1-9]"$1" + "}"); 
    rg =/\{[^}.]*}/gi;
    t3 = t3.replace(rg,"");
    rg =/(\\pos\([0-9]*,[0-9]*\)})/gi;
    t3 = t3.replace(rg,"{" + "$1"); 
    }
  </Script>
  <script language="VBScript">
  set ad=CreateObject("adodb.stream")
  set af=CreateObject("adodb.stream")
  set ass=CreateObject("adodb.stream")
  ad.open
  af.open
  ass.open
  ad.Charset=cInput
  af.Charset=cOutput
  ass.Charset=cOutput
  Set objArgs = WScript.Arguments
  For I = 0 to objArgs.Count - 1
    ad.LoadFromFile(objArgs(I))
    z=0
    gg=left(objArgs(I),len(objArgs(I))-3)&"srt"
    Do While ad.eos <> True
      ss =ad.ReadText(-2)
      if left(ss,8)="Dialogue" then 
        ss=replace(ss,",,",",d,")
        rrr
        t3=replace(t3,"\n",vbcrlf)
        t3=replace(t3,"\N",vbcrlf)
        z=z+1
        af.writetext z,1
        af.writetext t1 & " --> " & t2,1
        af.writetext t3 & vbcrlf & vbcrlf
      else 
        ass.writetext ss,1
      end if
    Loop
    af.savetofile gg,2
    ass.savetofile gg&".style",2
  Next
  if i=0 then 
    msgbox "Please drag files to me!",,"Error!"
  else
    msgbox "Converted "&i&" file(s).",,"All Over!"
  end if
  </Script>
</job>

Windows 脚本 (.wsf) 文件是一个包含可扩展标记语言(XML)代码的文本文档，它结合了若干功能，提高了脚本编程的灵活性。由于 Windows 脚本文件并不局限于特定的引擎，它们能够包含所有遵循 ActiveX(R)规范的脚本引擎的脚本。

上面的脚本文件同时包含了JScript和VBScript的代码。问题在于，有这个必要么？单纯用JScript或者VBScript都可以实现，为什么要混用不同的语言呢？JScript在代码中的作用仅仅是正则表达式而已，一个合理的推断是作者不会VBScript的正则表达式，或者嫌VBScript的正则表达式太麻烦。就算撇开语言混杂不说，上面代码的风格实在是不敢恭维。

下面是我写的ass2srt.vbs，也许比上面的代码好一点点罢。

Option Explicit
Const Encoding = "unicode" 'assume unicode

Dim shell, folder, fso, ext, i, args
Set shell = CreateObject("Shell.Application")
Set fso = CreateObject("scripting.filesystemobject")
Set args = WScript.Arguments

If args.Count = 0 Then
  Set folder = shell.BrowseForFolder(0, "请选择ASS字幕所在的文件夹", 1)
  If folder Is Nothing Then WScript.Quit
  For Each i In fso.GetFolder(folder.Self.Path).Files
    ext = LCase(fso.GetExtensionName(i.Path))
    If ext = "ass" Or ext = "ssa" Then
      ASS2SRT i.Path, Encoding
    End If
  Next
Else
  For i = 0 To args.Count - 1
    ASS2SRT args(i), Encoding
  Next
End If

MsgBox CInt(i) & " file(s) Converted!", vbInformation

Function ASS2SRT(path, charset)
  Const adTypeText = 2
  Const adReadLine = -2
  Const adSaveCreateOverWrite = 2
  Dim ass, srt, re, str, arr, s, e, t, i
  
  Set ass = CreateObject("ADODB.Stream")
  Set srt = CreateObject("ADODB.Stream")
  Set re = New RegExp
  
  re.Global = True
  re.IgnoreCase = True
  re.Pattern = "\{.*"
  
  ass.Type = adTypeText
  ass.Charset = charset
  ass.Open
  ass.LoadFromFile path
  
  srt.Type = adTypeText
  srt.Charset = "utf-8"
  srt.Open
  
  i = 0
  
  Do Until ass.EOS
    str = ass.ReadText(adReadLine)
    If Left(str, 8) = "Dialogue" Then
      i = i + 1
      arr = Split(str, ",", 10)
      s = "0" & arr(1) & "0" 'Start time
      e = "0" & arr(2) & "0" 'End time
      t = arr(9) 'Text
      s = Replace(s, ".", ",")
      e = Replace(e, ".", ",")
      t = re.Replace(t, "")
      t = Replace(t, "\n", vbCrLf)
      t = Replace(t, "\N", vbCrLf)
      srt.WriteText i & vbCrLf
      srt.WriteText s & " --> " & e & vbCrLf
      srt.WriteText t & vbCrLf & vbCrLf
    End If
  Loop
  
  path = Left(path, Len(path) - 3) & "srt"
  srt.SaveToFile path, adSaveCreateOverWrite
End Function

把上面代码保存为ass2srt.vbs，然后将需要转换的ass/ssa字幕拖动到ass2srt.vbs脚本上即可。如果需要批量转换的ass/ssa字幕比较多，可以先把它们放到同一个文件夹里，然后直接双击运行ass2srt.vbs，选择字幕所在的文件夹即可。
