Abstract
Disclosed is an audio follow video mixer incorporating a manual crossfade learn feature. According to the invention, an operator may set the mixer so that a custom crossfade operation performed manually is stored in memory. The custom crossfade can then be uploaded to a video editor unit where it may be stored in the edit decision list. Thereafter, the stored custom crossfade may be downloaded from the video editor.
Claims11
An audio follow video mixer system for performing a crossfade operation between a first audio channel having a first amplitude and a second audio channel having a second amplitude comprising,
- an audio mixer device which includes:
- gain control means for adjusting the amplitudes of the first audio channel and the second audio channel, said gain control means including means for manually controlling the adjustment of the amplitude of the first audio channel and the second audio channel and means for providing signals indicating the adjustment made to the first audio channel and the second audio channel;
- processor means for receiving said adjustment indicating signals;
- mixer memory means for storing data corresponding to said adjustment indicating signals;
- a first control member provided on a display portion of said audio follow video mixer, said first control member being operable to provide a store signal to said processor means to cause said processor means to provide said data corresponding to said adjustment indicating signals to said memory means;
- and
- a second control member provided on said display portion operable to cause said processor means to control said gain control means to adjust the amplitudes of the first audio channel and the second audio channel in accordance with said data stored in the memory means;
- and
- a video editor located remotely from said audio mixer device, said video editor being operatively coupled to said audio mixer device to receive said data stored in said mixer memory means;
- wherein said video editor includes editor memory means for storing said data and means for transmitting said data to said mixer apparatus.
7 more elements
An audio crossfade control apparatus comprising:
- an audio follow video mixer console;
- a gain control circuit provided in said mixer console for adjusting the respective amplitudes of a first output audio channel and a second output audio channel;
- a first manual adjustment member and a second manual adjustment member disposed on said mixer console and providing respective gain control signals to said gain control circuit to cause said gain control circuit to adjust said amplitudes of said first output audio channel and said second output audio channel;
- first memory means provided in said mixer console for storing data;
- first processor means operatively coupled to said gain control circuit, said memory means, said first manual adjustment member and said second manual adjustment member, said processor means providing data to said memory means which corresponds to said gain control signals;
- store control means provided on said mixer console operable to generate a store signal which is input to said processor means, said store signal causing said processor means to provide said data to said memory means;
- recall control means provided on said mixer console operable to generate a recall signal which is input to said processor means, said recall signal causing said processor means to read said data from said memory means and to provide gain control signals to said gain control circuit based on said data from said memory means;
- a video editor having second processor means and second memory means;
- and
- interface means for operatively coupling said first processor means within said mixer console with said second processor means with said video editor;
- wherein said video editor is operable to generate a second recall signal remotely causing said processor means to read said data from said memory means and to provide gain control signals to said gain control circuit based on said data from said memory means.
