Abstract

For the sake of improving the operability in edits of audio and video signals in a video editor, the video editor of the present invention is constituted in such that at least two types each of audio and video signals are inputted, and levels of the audio and the video signals inputted are controlled in response to the operations of faders. The video editor is provided with a first fader; a second fader; and a control means for controlling simultaneously a ratio of composition in two types of video signals inputted with levels of two types of audio signals inputted in response to the operation of the aforesaid first fader, and only the levels of the audio signals inputted being controlled in response to the aforesaid second fader.

Claims5

Dependent claims

A video editor wherein at least two each of audio and video signals are inputted, and levels of the audio and the video signals inputted are controlled in response to the operations of faders, comprising:

a first fader which a user can operate for indicating a ratio of composition in said at least two video signals inputted,
a second fader which a user can operate for indicating the levels of said at least two audio signals inputted,
a synchronous/asynchronous mechanism for establishing whether the levels of said at least two audio signals inputted are synchronous or asynchronous with operations of said first fader,
a first level controller for controlling a ratio of composition in said at least two video signals inputted in response to the operations of said first fader, and
a second level controller for controlling the levels of said at least two audio signals inputted in response to operations of said first fader when said mechanism is establishing levels synchronous with the operations of said first fader, said second level controller controlling the levels of said at least two audio signals inputted in response to said second fader when said mechanism is establishing levels asynchronous with the operations of said first fader.
