	An alternative method is to use VB Script. This example will transcode all files from one folder to another. It will also wait for each file to finish transcoding before starting the next. Create the script <code>transcode.vbs</code>, in the VLC installation folder, default <code>~~C:\Program Files~~\VideoLAN\VLC</code>. Change the <code>strSource</code> and <code>strTarget</code> in the example to match your requirements. Start a "DOS Box", Start → Run → cmd then change to the VLC folder and run the script <code>"cscript transcode.vbs"</code>.		An alternative method is to use VB Script.

	As an example, here is a bash script that will take a <code>.mpg</code> file as generated by an [[DVB]] capture device and transcode it into an [[MPEG4]] file using the [[h.264]] codec. Copy it to a file, for example <code>dvb2mp4</code>, and make it executable. It should work on any operating system that has bash, including windows if [~~http~~://www.cygwin.com Cygwin] is installed. It uses the cropping parameters proposed at [[Wikipedia:Overscan amounts\|overscan amounts]] adapted so that the dimensions are divisible by 16 for better encoding.
