How to make and edit pictures during video?

Two materials are resized and placed on the same screen, such as a video size, the picture is on the left and the video is on the right.

Film editing is to screen, select, decompose and combine a large number of materials shot in film production, and finally complete a work with clear meaning, distinct theme, strong artistic appeal and coherence.

Starting from American director Griffith, the art of editing was produced by using the method of lens shooting and then connecting these lens groups. Editing is an indispensable work in the process of film production, and it is also the last re-creation in the process of film art creation. French new wave film director Godard: editing is the official beginning of film creation.

The word "edit" means "edit" in English and "cut" in German. In French, the word "edit" was originally an architectural term, meaning "composition and assembly". Later, it was used in movies and transliterated into Chinese, which is "montage". In China's films, it is very accurate to translate this word into "editing".

The word "editing" is immediately edited, which can be directly associated with editing like German, while retaining the meanings of "fusion" and "editing" in English and French. When people use the foreign word "montage" in Chinese, they often refer to the means with special effects in editing, such as parallel montage, narrative montage, metaphor montage and contrast montage.
