Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
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.
Claim 2
Dependent Claim
204 words
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.
Claim 3
Dependent Claim
45 words
A video editor as claimed in claim 1 further comprising a fader controller which shifts an operating position of said second fader in response to the operations of said first fader when said mechanism is establishing levels synchronous with the operations of said first fader.
Claim 4
Dependent Claim
96 words
A video editor as claimed in claim 1 wherein said at least two audio signals inputted comprise first and second audio signals, said second fader is provided to each of said first and second audio signals, and said mechanism establishes a level of said first audio signal to be either synchronous or asynchronous with the operations of said first fader independently of said second audio signal, and said mechanism establishes a level of said second audio signal to be either synchronous or asynchronous with the operations of said first fader independently of said first audio signal.
Claim 5
Dependent Claim
60 words
A video editor as claimed in claim 1 further comprising an adjuster which sets a level control for each of said at least two audio signals inputted in response to the operations of said first fader, said second level controller further controlling the level for said at least two audio signals inputted in response to the setting of said adjuster.
Claim 6
Dependent Claim
37 words
A video editor as claimed in claim 1 wherein said first fader and said second fader are displayed on a screen of a computer, said first and second faders being operable in response to a pointing device.
