When we think about Non Linear Editing software (NLEs) certain words tend to jump into our minds, Avid, Final Cut Pro, and now even Adobe is making a serious dash into the digital editing arena with CS5.
But when some of these NLEs did not even exist, there was a piece of software helping to define the non-linear editing space; it's an editing system know as Lightworks. Until around the mid 1990's, Lightworks competed in the NLE arena with many top editors world wide using it as their tool of choice in the edit room.
In the United Kingdom, an editor named Chris Gill -- with credits like "28 Weeks Later" and the Ricky Gervais directed, "The Invention of Lying" to his name -- was gleefully, whenever possible, sitting in front of a Lightworks editing station, his preferred editing tool.
