NLE is non destructive: that is, your video files remain completely intact. The computer merely creates markers to indicate the location of cuts, dissolves, color correction, etc.

When you play back your edit from the timeline --- the computer calculates from all the information in the markers and displays the bits and pieces of your video on the monitor as a coherent video stream.

When the work is rendered the computer combines all the data points into a coherent stream and exports the results to the file format of your choice, rather than sending the stream to your monitor.
