The "blue line" in editing is a visual cue used in film and video editing software to denote the limits of a ‘shot’ or video clip. It's usually an underline drawn underneath the clip, and it separates each clip or scene for easy visual identification.
The blue line helps editors work faster by providing a quick cue of where each clip starts and ends. When watching the timeline, cuts between each clip are represented by the blue line moving up and down the timeline, hence its name.
Some key benefits of the blue line include:
-Provides a clear visual representation of where one clip ends and another begins.
-Helps you quickly find a clip among hundreds of others on the timeline.
-Signifies where a clip’s in and out points should be.
-May be used to indicate where to make precise splices (cuts) between video clips without needing to use video ‘guides’ such as a countdown or special effects.
Overall, the blue line is an extremely useful tool helpful in the editing process and is essential for any editor who wants to maintain the precise timing and cutting of their edit.
