What is Timecode?

In your own words, explain what timecode is to someone who has no idea. What is it? Why is it so important for editing video?

A video is a cumulation of multiple photos displayed in sequential order. Time code allows the editor to define the frame in a sequence indicated by the CTI, or current time indicator. The CTI will most often be seen as a long vertical line on the timeline panel. The four groups of numbers are hours, minutes, seconds, and frames. Time codes are important to editing a video because it helps pin point a certain frame at a specific time. For example, time codes can be specifically typed in the editing software to reach an accurate frame. A full length movie will require more attention to time code in order to differentiate from good shots and bad shots. Professional videos require more attention to detail of frames in order to maintain continuity between shots or tell the story more effectively.
