research development of editing technology

In 1885, the cinematographe was invented by the Lumiere Brothers, this was a device that recorded, captured and projected moving images. Shortly after the Lumiere Brothers invented the cinematographe, Edwin. s. porter showed that a film didn't need to be one long take, and instead created a story that was different to the original footage story.
The film "for love of God" by D.W Griffiths was the first film with a continuity cut when a scene cut, he then developed a way to show emotion int he film, instead of just the actors shwoing. What he did was use different camera angles and changing the speed of the editing. He later went on to make "the birth of a nation" which included many camera techniques filmmaker use today like panoramic long shots, still shots, cross cutting, iris effect and panning shots.
Lev Kuleshov discovered the Kuleshov effect, which was a montage effect. The potentials of montage were explored by Eisenstein and Dziga Vertov as Eisenstein's in 1925 thought he could by using a montage in film, could explore different ideas in his film Battleship Potemkin- montage.
Before computer editing, there was analog editing. The negative of the film would be cut down and then pasted back into order, it was then put though a Moviola or K.E.M machine.

Editing on a computer is much easier and faster, because it is you can cut, paste and put togetehr all on one machine as analog you would need to cut the negatives. Many editing software's are available such as Imovie or Adobe Premier pro. When editing on these software you can also add different visual and sound effects.
Offline editing is when the raw footage gets copied and edited in post production without effecting the cameras original footage. The name offline editing is referred to when he footage is not being edited by any other device unlike online editing, which comes after the offline editing. Offline editing has been used since near the beginning of editing, however this process was usually used to assemble scenes together than final editing, as if done wrong or imperfectly, physically cutting the image could lead to the picture breaking up.
Online editing is the final editing process, which takes place after offline editing. Online editing has mainly now been taken over by computer editing software like Adobe, that have NLE (non linear editing systems). Online editing is more automatic than offline as it is under the control of another device.
