Hi,
I'm trying to replicate one of the @jetdv script : "Remove Silent Areas from an Audio Track in VEGAS - Part 2" (
in order to modify it later in a video bass shake effect.
However i have an issue i located but i'm unable to fix it :
- The script works until it reach the first audio value and send the following error :
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Input string was not in a correct format.
at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt)
at Test_Script.Class1.ProcessLog(String path)
at Test_Script.Class1.Main(Vegas vegas)
The faulty code line is this one : trackVolume = Convert.ToDouble(pieces[2]);
Look like the value is not converted correctly to double.
Is there a solution possible to this issue ?
