VBScript and FFMPEG

[Ads79]

I've got a strange one here that I can't figure out. I basically want to pipe the output from calling ffmpeg to a text file. I am using ffmpeg version SVN-r23607.
If I create a batch file with the following statement it works. All of the output is saved to the text file.

"C:\ffmpeg\ffmpeg.exe" -i "FileInput.mp4" -vcodec copy -acodec copy "FileOutput.mp4" 2> "LogFile.txt"

If I then convert the same statement to VBScript it no longer works. It doesn't even run the command.

Set objShell = CreateObject("Wscript.Shell")
Cmd = Chr(34) & "C:\ffmpeg\ffmpeg.exe" & Chr(34) & " -i " & Chr(34) & "FileInput.mp4" & Chr(34) & " -vcodec copy -acodec copy " & Chr(34) & "FileOutput.mp4" & Chr(34) & " 2> " & Chr(34) & "LogFile.txt" & Chr(34)
objShell.Run Cmd, 10, True

If I get rid of the part that outputs the info to a text file, then the VBScript works but obviously doesn't save the output to the text file.
ie

Set objShell = CreateObject("Wscript.Shell")
Cmd = Chr(34) & "C:\ffmpeg\ffmpeg.exe" & Chr(34) & " -i " & Chr(34) & "FileInput.mp4" & Chr(34) & " -vcodec copy -acodec copy " & Chr(34) & "FileOutput.mp4" & Chr(34)
objShell.Run Cmd, 10, True

Very confused as to why it works in a batch file but the same cmd doesn't work in VBScript.
Is there another way to capture this output in VBScript instead of dumping it out to a text file. I've heard "stdOut" could be used but I can't get this to work either. If someone has an example of this it would be great.

For file redirection to work, you have to run the command shell.

Set objShell = CreateObject("Wscript.Shell")
Cmd = "cmd.exe /c " & Chr(34) & "C:\ffmpeg\ffmpeg.exe" & Chr(34) & " -i " & Chr(34) & "FileInput.mp4" & Chr(34) & " -vcodec copy -acodec copy " & Chr(34) & "FileOutput.mp4" & Chr(34) & " 2> " & Chr(34) & "LogFile.txt" & Chr(34)
objShell.Run Cmd, 10, True

Thanks, that solved the problem. I just had to wrap the command up in quotes in order for it to work. As so...

Set objShell = CreateObject("Wscript.Shell")
Cmd = "cmd.exe /c " & Chr(34) & Chr(34) & "C:\ffmpeg\ffmpeg.exe" & Chr(34) & " -i " & Chr(34)  & "FileInput.mp4" & Chr(34) & " -vcodec copy -acodec copy "  & Chr(34) & "FileOutput.mp4" & Chr(34) & " 2> " &  Chr(34) & "LogFile.txt" & Chr(34) & Chr(34)
objShell.Run Cmd, 10, True
