Filename

The filename can be customized by going to YouTube Center Settings -> Download -> Filename. By editing this text field the filename can be customized. You could eg write: "This is my awesome custom filename text", but you probably want something a little more dynamic. This is here the special tags are used. You can combine these tags and normal text to create your own unique filename for every YouTube video you have downloaded. You can combine them like this: "{pubdays}-{pubmonth}-{pubyear} - The video {filename} I have downloaded", which will result in something like this: "27-3-2012 - The video RANDOM TITLE I have downloaded".
