Problems solved by technology

For example, to replace a section of picture in the current program file with a piece of picture from other sub-shots, the existing technology does not have the function of direct replacement, and can only manually intercept the picture for a period of time and then cover it, and the start and end time must be consistent during the manual interception process. It is very time-consuming to replace multiple screens in the program file
[0005] To sum up, in the prior art, the replacement of program files needs to be manually intercepted from the sub-camera images, and the start and end times of the two need to be consistent. When there are many images to be replaced, it will consume too much time and reduce work efficiency. Unable to meet the requirements of refined editing and rapid production of programs

Embodiment 1

[0022] figure 1 It is a flowchart of a method for replacing track materials in a multi-channel system provided by Embodiment 1 of the present invention.

[0023] Such as figure 1 As shown, the method includes the following steps:

[0024] Step 101, intercept material units from multi-channel material to form track material. The track material is composed of multiple material units.

[0025] Step 102: Obtain source replacement unit information, the acquired source replacement unit information includes: start and end time of the source replacement unit, and the source replacement unit is a selected material unit.

[0026] Step 103, receiving a replacement instruction.

[0027] The replacement instruction includes: an instruction for replacing an audio unit, replacing a video unit, or binding and replacing an audio unit and a video unit.

[0028] Step 104: Parse the replacement instruction to obtain information about the destination channel. The information about the destina...

Embodiment 2

[0034] figure 2 It is a flowchart of a method for replacing track material in a multi-channel system provided by Embodiment 2 of the present invention.

[0035] Such as figure 2 As shown, the method includes the following steps:

[0036] Step 201, the images captured synchronously by multiple cameras form multi-channel materials.

[0037] Step 202, intercept material units from the multi-channel material to form track material. The track material is composed of multiple material units. Through the above steps, recording and editing can be performed synchronously, and the time code of the multi-track material is kept consistent with the time code of the multi-channel material.

[0038] Step 203: Obtain source replacement unit information, the acquired source replacement unit information includes: start and end time of source replacement unit, and the source replacement unit is a selected material unit.

[0039] Step 204: Obtain picture information in the multi-channel mat...

Embodiment 3

[0047] image 3 It is a flow chart of the synchronous search method provided by Embodiment 3 of the present invention.

[0048] Such as image 3 Said, the method includes the following steps:

[0049] Step 301, receiving a user synchronization search instruction.

[0050] Step 302, analyzing the time code information contained in the synchronization search command and sending it to the material module. The material module includes: a multi-channel material module and a track material module, both of which have the same time code. The time code includes: hour, minute, second and frame.

[0051] Step 303, the material module performs a synchronization search according to the time code information.

[0052] Step 304 , displaying the synchronously searched pictures, and displaying the synchronously searched pictures on 4-16 monitors.

[0053] The embodiment of the present invention searches the material modules synchronously and directly locates them on the defined time code...

Abstract

The invention discloses a track material replacement method in a multi-channel system. The method comprises intercepting a material unit from multi-channel materials to obtain track materials; acquiring source replacement unit information including a source replacement unit start and stop time, the source replacement unit being the selected material unit; receiving a replacement command; analyzing the replacement command to obtain destination channel information; intercepting a unit, of which the start and stop time is identical to that of the source replacement unit, from the destination channel according to the received replacement command to form a new unit; replacing the source replacement unit by the new unit; and displaying the replacement result. According to the invention, the method can greatly improve the program production efficiency on the premise of satisfying the fine program editing, thereby improving the program production quality and lowering the program production cost.

Description

technical field [0001] The invention relates to the field of video editing, in particular to a method for replacing track materials in a multi-channel system. Background technique [0002] The party programs or sports competition programs watched by the audience are all recorded by multiple cameras and then presented by means of editing. [0003] Simply speaking, the editing of the video is to intersperse and combine the pictures captured by multiple lenses, and this combination is set according to the actual environment of the scene. Sometimes after recording a program, it needs to be broadcast immediately or even live broadcast, so we don’t have time for too tedious post-editing steps. Therefore, the most commonly used method is to edit the program while recording it, and then generate the program file to save time. [0004] Since the generated program file is generated by synchronous editing during the recording process of the program, it is necessary to modify the edit...
