Embodiment 1

[0047] A method for multi-channel audio and video synchronous recording and multi-track synchronous editing. The audio and video acquisition equipment used includes a microphone, a video camera, and a camera, and each audio and video acquisition equipment is connected to a computer equipped with audio and video processing software. The audio and video processing software includes two functional interfaces, namely the audio and video recording interface and the audio and video editing interface. The audio and video recording interface is mainly used to set and preview the audio and video information of each audio and video collection device. Synchronous editing of audio and video recording files and preview of editing results. The main operations in the audio and video editing interface include: synchronous loading of multiple audio and video recording files, time point marking of multiple tracks, synchronous editing of multiple audio and video recording files, and the results o...

Embodiment 2

[0052] On the basis of Example 1, as Figure 8 As shown, in the process of synchronous editing, 11'26" and 11'45" on the time scale in the audio and video editing interface are used as two divided time points, and at the two time points of 11'26" and 11'45" In the constituted time period, all audio and video clips (including audio, video 1, video 2, and video 3) can be selected at the same time, and at the same time, the audio and video recording files on each channel can be freely switched and displayed, so as to determine the display and The audio and video clips on a certain track are played, and when the audio and video clips are selected, the current operation is recorded in the editing script file. For example: during the period of 11′26″-11′45″ recorded on the editing script file, play video 2 on the second track, and from 11′45″ to the end, play video 1 on the first track. By specifying The audio and video on one channel to be selected and displayed among multiple aud...

Embodiment 3

[0054] On the basis of any of the above-mentioned embodiments, during the synchronous editing process, select two time points on the time scale as divisions, and click the "Delete" button in the audio and video editing interface to select the current audio files of all channels at the same time. The video clip is deleted. Such as Figure 5 As shown, all shaded parts are deleted parts. Such as Figure 9 As shown, take 11'26" and 11'45" on the time scale as two divided time points, and in the time period formed by the two time points of 11'26" and 11'45", click the audio and video editing interface The "Delete" button in the button can simultaneously select the current audio and video clips of all channels for deletion. While deleting the audio and video clips on each track, record the current operation in the edit script file, and move the subsequent audio and video clips of all channels forward synchronously. For example: it is recorded on the editing script file that the ...

Abstract

The invention discloses a multi-channel audio and video synchronous recording and multi-rail synchronous editing method, and relates to the technical field of audio and video processing. The method comprises the following steps that 1, multiple audios and videos are subjected to synchronous audio and video acquisition to obtain multiple independent and synchronous audio and video recording files;and 2, the multiple audio and video recording files are subjected to synchronous editing operation to obtain editing result files. Audio and video acquisition equipment is adopted to conduct audio andvideo acquisition, and audio and video processing software is adopted to synchronously load the acquired audio and video recording files and conduct synchronous editing operation on the multiple audio and video recording files. The method has the advantages that the audio and video information of multiple channels keep synchronous recording, the audio and video result files of multiple channels are subjected to fast synchronous editing, therefore, the problem that follow-up editing is difficult when various audio and video acquisition equipment asynchronously acquire the audios and videos isavoided, the operations of manually synchronizing and connecting audio and video pictures of the various channels are avoided, and the clipping efficiency and the clipping quality are high.

Description

technical field [0001] The invention relates to the technical field of audio and video processing, in particular to a method for multi-channel audio and video synchronous recording and multi-track synchronous editing. Background technique [0002] In the program production process of multi-camera positions, firstly, it is necessary to collect the video signals output by multiple cameras, and at the same time, it is also necessary to collect the time code (Time Code, TC) of the video signal, and combine the video signal and the time code together. And write it into the computer to form the program material for later editing. In the post-editing of the program, materials from multiple camera positions in the same scene need to maintain the original relative time relationship on different video tracks. Therefore, certain synchronization techniques need to be adopted, such as selecting a specific video frame as the Time reference, or capture synchronized time code while capturi...
