我有一个简单格式化的文本文件(编辑决策列表),其中包含数字行(时间码帧速率为25),后跟属性行(名称等)。
最终我想:
检索以* FROM CLIP NAME:
开头的行和上面的行/行(时间码)。在这一行是时间码,有4组数字,每组表示为00:00:00:00 - 或HH:MM:SS:FF或小时,分钟,秒,帧。然后我放弃其他一切。
使用前2个数字组(它们是开始和结束时间)来推导持续时间。
然后将持续时间附加到剪辑名称行。
将文件另存为" SourceFileName" .txt(原文为.edl,因此无法覆盖)。
由于我的帧速率是每秒25帧,我希望将每个组分解为帧数。
我希望将时间码转换为每秒25帧:
这会产生一组00:02:20:01 = 3501帧
3501模数(%)25 = 1帧余数
140/60 = 2分钟
然后我会从第二组中减去第一组以找出差异。一旦我有了差异,我就会将帧计数重新组合成一个时间码,只需要反转数学。
我无法确定如何指定名称行,然后使用前4个组中的前两个来获取前一行的arithemetic。
到目前为止(不远)我只为用户建立了一种在桌面上定义源文件的方法。
Option Explicit
Dim fso, oFile, y
Set fso = CreateObject("Scripting.FileSystemObject")
'get user to open file name
y = InputBox("name of file to save")
'next line opens a file with that name
Set oFile = fso.OpenTextfile(y & ".edl")
更新 :修改后的脚本,但我甚至无法对选定的行及其开始/结束值进行分组
Option Explicit
Dim fso, oFile, y, re, prev, line, matches
Set fso = createobject("Scripting.FileSystemObject")
'get user to open file name
y = inputbox("name of file to save")
'next line opens a file with that name
Set oFile = fso.Opentextfile(y&".edl")
Do Until oFile.AtEndOfStream
line = oFile.ReadLine
'At this point the variable prev either is empty (during the first loop
'cycle) or holds the content of the previous line.
If Left(line, 21) = "* FROM CLIP NAME: " Then
'do stuff here
Set re = New RegExp
re.Pattern = "C (\d{2}:\d{2}:\d{2}:\d{2}) (\d{2}:\d{2}:\d{2}:\d{2})"
matches = re.Execute(prev)
'print each pair of prev & Pattern match
prev = (line) & (matches)
wscript.echo prev
'don't know how to use submatch values
End If
Loop

我必须在VBScript中执行此操作,以便我们可以在各种用户的Windows桌面上运行它。我们无法安装其他可执行文件或从命令提示符运行。我没有管理员安装权限。

在阅读文件时,请记住单独变量中的上一行:
Do Until oFile.AtEndOfStream
line = oFile.ReadLine
'At this point the variable prev either is empty (during the first loop
'cycle) or holds the content of the previous line.
If Left(line, 19) = "* FROM CLIP NAME: " Then
'do stuff here
End If
prev = line
Loop
使用regular expression提取开始和结束时间戳。
Set re = New RegExp
re.Pattern = " (\d{2}:\d{2}:\d{2}:\d{2}) (\d{2}:\d{2}:\d{2}:\d{2})"
Set matches = re.Execute(prev)
时间戳可用作matches
的第一个和第二个子匹配。
请注意,输入文件中的某些FROM CLIP NAME
行似乎没有时间戳行,因此您需要处理它。
