Linear editing video recorder and linear editing method

Abstract

This application provides a linear editing video recorder and a linear editing method. The linear editing video recorder comprises a hard disk, a graphics card, a video card, an audio card, a control operation panel, an IVDR disk cartridge, a serial port signal processing module, a timeline engine module, and a file reading and writing module, wherein the control operation panel comprises a display screen; the IVDR disk cartridge comprises a playing cartridge and a recording cartridge; the video card and the audio card are used for acquiring and outputting video signals and audio signals respectively; the serial port signal processing module is used for transmitting an operating command sent by the control operation panel to the other modules and sending feedback information of the other modules to the display screen of the control operation panel for display; the timeline engine module is used for copying segments of materials onto a timeline track to be recorded in a virtual manner for editing preview according to in-and-out points of each disk; and the file reading and writing module is used for writing the segments of materials into the hard disk. The linear editing video recorder and the linear editing method adopt the hard disk for storage and combine the hard disk with a timeline architecture, thereby solving the problem that the traditional linear editor is not capable of random access.

Description

technical field [0001] The present application relates to the technical field of radio and television video editing, in particular to a linear editing video recorder and a linear editing method. Background technique [0002] In the production of broadcasting and television, it is necessary to edit the video, that is, to connect the materials into continuous pictures according to the requirements of the program content. [0003] At present, most video recorders for video editing are tape video recorders. By using linear editing, the materials are sequentially edited into continuous pictures, and then a certain piece of material is replaced with the same length by insert editing. When it needs to be deleted, shortened or lengthened If there is a certain section of material in the middle, all the pictures after this section of material must be erased and re-recorded. [0004] The deficiencies in the prior art are: [0005] It is difficult for the existing video tape recorder ...

AI Technical Summary

Problems solved by technology

[0006] The embodiment of the present application proposes a linear editing video recorder and a linear editing method to solve the technical problem that the tape video recorder in the prior art is difficult to complete operations such as random insertion or deletion, resulting in low editing efficiency
