1. A video switcher apparatus having no time code input terminal, comprising:
- input means for inputting first video signals of moving images from a plurality of moving image video capture systems which do not have a time code output function;
processing means for video effect processing the first video signals of two or more video capture systems input into said input means and generating video effect processed second video signals having effects such as at least dissolves and wipes;
time code generating means for generating a first time code based only on a preset value independent of external time code input; and
time code adding means for (a) adding the first time code generated by said time code generating means to the video effect processed second video signals generated by said processing means, and (b) adding a second time code to the first video signals which is input into said input means, the second time code is obtained by adding a value corresponding to video effect processing delay time at said processing means to a value of the first time code generated by said time code generating means, wherein said first and second time codes are mutually synchronous.

Abstract
A video processing apparatus is provided. The video processing apparatus includes: an inputter inputting video signals of a plurality of systems, and a processor generating processed video signals by performing switching on the video signals of two or more systems input into the inputter. Further, the video processing apparatus includes: a time code generator generating a time code, and a time code adder adding the time code to the input video signals and the generated video signals respectively, outputs the video signals with the time code to be recorded in a recording medium.
