PROBLEM TO BE SOLVED: To provide a video audio file system for eliminating the need for re-collecting broadcast materials attendant on the correction of video and audio levels or the correction of a field angle to a video audio server. SOLUTION: The video audio file system includes: a first video audio level variable apparatus 2 connected to a signal transmission system for externally transmitting the broadcast materials of the video audio server, and a second video audio level variable apparatus 3 connected to a monitor system for monitoring the broadcast materials of the video audio server. The video audio file system adjusts a video level, an audio level, and a field angle of a signal outputted from the second video audio level variable apparatus 3 on the basis of level revision data for revising a video level and an audio level and field angle revision data for revising the field angle, and adjusts a video level, an audio level, and a field angle of a signal outputted from the first video audio level variable apparatus 2 on the basis of a confirmed value of the level revision data and the field angle revision data designated by an operator.
