Linear editing is a traditional method of making a film in which scenes are edited in a strictly linear order, as they were shot. This approach was used before the introduction of digital technologies and non-linear editing systems.

Here are some key features of linear editing:

Sequence of scenes: Scenes are edited in the order in which they were shot, so changing the order of the scenes requires reshooting the entire film.
Limited flexibility: With linear editing, the ability to change the structure and chronology of a movie is constrained, limiting creative freedom.
Time-consuming: Changing or correcting any part of the movie requires the editor to redo and reassemble all the previous scenes, which takes a lot of time.
Limited technical capabilities: Linear editing often limits the use of complex technical effects, animation and other innovative techniques.
Fixed structure: The fixed structure of the movie makes it difficult to correct mistakes or change the creative vision after the first cut.
