Answer 1

In some cases you want to be able to do more like: - Kill the exe in case it hung. - Be able to abort the exe. - Get the exe output (to the standard output and the standard error) - Run it asynchronously.

Answer 2

You've got all the pieces in your question. It's just a matter of putting it all together.

Something such as the following should work:

public class Test {
    public static void main(String[] args) throws Exception {

        String[] cmd = { "C:\\E.M. TVCC\\TVCC.exe", "-f E:\\TestVideo\\01.avi", "-o E:\\OutputFiles\\target.3gp" };
        Process p = Runtime.getRuntime().exec(cmd);
        p.waitFor();
    }
}

That said, hard coding paths like this isn't a good idea, you should read them from somewhere; arguments to your program, a properties file, etc.
