Background technique

In the prior art, commonly used ultra-high-definition video editing methods include: original bit rate editing, proxy bit rate editing, and local decoding based on wavelet transform coding. However, when using original bit rate editing to edit and produce ultra-high-definition video materials, due to the large amount of data per unit length of ultra-high-definition video materials, on the one hand, the performance requirements of the host used for editing are relatively high. When editing multi-track ultra-high-definition video, it needs to wait for processing, which is inefficient; when using proxy bitrate editing to edit and produce ultra-high-definition video materials, although the performance requirements of the host used for editing can be reduced compared with original bitrate editing, it is still inefficient. , because it is necessary to generate the low-bit rate version corresponding to the ultra-high-definition video material in advance before the video material is recorded and uploaded. On the one hand, the low-bit rate copy will cause a certain storage overhead. On the other hand, the system used for proxy bit rate editing is more complex, and the operation and maintenance is difficult; when using local decoding of wavelet transform coding for ultra-high-definition video editing, although it can reduce The amount of decoding calculation, thereby reducing the performance requirements of the host used for editing, however, it is only applicable to limited objects (only applicable to shrinking at a fixed ratio such as 1/4, 1/16, etc.), and the compression algorithm is single, and the image quality is limited .

Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

Referring to FIG. 1 , an embodiment of the present application provides a video editing system 10 for editing and producing a video. In this embodiment, the video editing system 10 is used to edit and produce a video, and generate a broadcast file that satisfies the broadcast television standard (for example, the format standard in the broadcast television standard).

In this embodiment, the video editing system 10 includes an editing server 11 and a decoding server 12 that are communicatively connected.

The editing server 11 is used to send a video material acquisition request. The video material acquisition request includes the identification of the video to be acquired and the basic format standard. The basic format standard is adapted to the editing server 11 . Optionally, the basic format standard may be the minimum format standard that can be used for editing by the editing server 11, for example, meeting any format standard of 720P, 2K, 4K, etc. of the broadcast television standard. Thereby, the processing pressure of the editing server 11 can be reduced, in other words, the performance requirements on the editing server 11 can be reduced.

It should be noted that the adaptation of the basic format standard to the editing server 11 means that the editing server 11 can perform relatively smooth editing and production of the video material of the basic format standard under its performance conditions. Exemplarily, when editing and producing a video material of a corresponding format standard, if the CPU occupancy rate is lower than a preset value (for example, 80%), it is considered that the editing server 11 can perform the video of the format standard under its performance conditions. The material is edited and produced more smoothly. Therefore, any format standard equal to or lower than this format standard can be regarded as the base format standard. For example, if the editing server 11 can edit and produce 8K standard video material relatively smoothly under its performance conditions, any of the format standards less than or equal to 8K can be regarded as the basic format standard.

It can be understood that the preset value can also be set to other values as required, for example, 50%, 60%, 70%, 90%, or a value between any two, which is not limited in this application.

In this embodiment, the video editing system 10 may further include a human-computer interaction device communicatively connected to the editing server 11 , such as a touch display screen, or a display screen and an input device (eg, a keyboard, a mouse, a controller, etc.) assemblies, etc. The editing server 11 can be integrated with the human-computer interaction device, or can be set separately. The user can input information through the human-computer interaction device. At this time, before sending the video material acquisition request, the editing server 11 is further configured to determine the format standard adapted to itself to obtain the basic format standard.

In one embodiment, the editing server 11 pre-stores an adaptation relationship table between server performance parameters and format standards. The editing server 11 may determine the format standard adapted to itself according to its own performance parameters and the adaptation relationship table. In this case, there may be a one-to-one correspondence between server performance parameters and format standards in the adaptation relationship table; or, a range of server performance parameters corresponds to one format standard. When a server performance parameter in the adaptation relationship table corresponds to multiple format standards (here, the editing server 11 can perform relatively smooth editing and production of video materials of any format standard among the multiple format standards under its performance conditions), The editing server 11 may display the corresponding format standard through the human-computer interaction device, and determine the format standard selected by the user as the basic format standard based on the user's selection instruction.

Optionally, the editing server 11 may determine the format standard suitable for itself when receiving the relevant information about the video material to be acquired that is input by the user through the human-computer interaction device.

Before sending the video material acquisition request, the editing server 11 is further configured to determine the video identifier to be acquired based on the user input information. Optionally, the user input information may include the storage location of the video material to be acquired, the corresponding time period, the name of the program to which it belongs, and the like. The editing server 11 may generate an identification of the video to be acquired based on the user input information.

After determining the basic format standard and the to-be-obtained video identifier, the editing server 11 is further configured to generate a video material acquisition request according to the basic format standard and the to-be-obtained video identifier.

The decoding server 12 is connected in communication with the editing server 11 and the video source 21, respectively.

The decoding server 12 is configured to receive the video material acquisition request, and acquire the original video material corresponding to the to-be-obtained video identifier from the video source 21 . The format standard of the original video material is the original format. The original format is different from the base format standard, and the resolution of the original format is higher than that of the base format standard. The original format can be any standard such as 720P, 2K, 4K, 8K, 10K, 16K, etc.

In this embodiment, after acquiring the original video material corresponding to the to-be-obtained video identifier, the decoding server 12 is further configured to decompress the original video material to generate uncompressed baseband data.

The decoding server 12 is further configured to process the original video material according to the original format and the basic format standard to obtain the video material to be edited. The format standard of the video material to be edited is the basic format standard. Specifically, the decoding server 12 is further configured to perform format transformation on the original video material according to the original format and the basic format standard (eg, through a format transformation algorithm such as a wavelet transform algorithm, a downsampling algorithm or a compression algorithm commonly used in the art). It can be understood that the specific process of performing the format transformation on the video material through the format transformation algorithm is the prior art in the art, and will not be described here.

The decoding server 12 is also used for sending the video material to be edited to the editing server 11 .

The editing server 12 is further configured to receive the video material to be edited, and edit the to-be-edited video material to obtain a program project file. The editing of the video material to be edited may include video editing operations such as adding subtitles, cropping, and arranging. The program project file may include the identification of the video material to be edited, and the editing script (including the timeline file, and the timeline position of the video material to be edited, etc.).

In this embodiment, the video editing system 10 may further include a composition server 13 .

The composition server 13 is connected in communication with the editing server 11 and the video source 21, respectively.

The composition server 13 is used to receive the program project file, obtain the original video material from the video source 21 according to the identification of the video material to be edited; perform packaging processing (for example, rendering, synthesis, etc.) on the original video material according to the timeline file and the timeline position, Generate a broadcast file. It should be noted that the original video material is packaged according to the timeline file and the timeline position, and the specific content of generating the broadcast file is the prior art in the art, and will not be described here.

It can be understood that, in other embodiments, the number of synthesis servers 13 may be multiple, and the multiple synthesis servers 13 are all connected in communication with the editing server 11 and the video source 21 . At this time, the multi-machine parallel technology can be used to package the original video material, thereby improving the efficiency of the synthesis work. It can be understood that since the multi-machine parallel technology is the prior art in the art, it is not described here.

It can be understood that, in other embodiments, the video material stored in the video source 21 may be dual-format encoded video material. The dual-format coded video material is formed based on the original video material, and includes the video material corresponding to the basic format standard. Please refer to FIG. 2 . FIG. 2 shows a brief flow of generating dual-format encoded video material based on the original video material, and after the dual-format encoded video material is stored in the video source 21 , the video source 21 communicates with the editing server 11 and the synthesis server 13 the interaction process between them. In this embodiment, the video material corresponding to the basic format standard is obtained by down-converting the original video material. The extended format video material is obtained by up-converting the video material corresponding to the basic format standard, and fusing the up-converted video material and the original video material. Then perform extended format encoding on the extended format video material, perform basic format encoding on the video material corresponding to the basic format standard, and integrate the encoded data to obtain dual-format encoded video material. That is to say, in this embodiment, the double-format encoded video material is a video material obtained by integrating the extended format video material and the video material corresponding to the basic format standard. The video material corresponding to the basic format standard is a video material obtained by down-converting the original video material based on the basic format standard and encoding the basic format. The extended-format video material is a video material obtained by performing extended-format encoding on the video material obtained by up-conversion of the video material corresponding to the basic format standard and the video material obtained by fusing the original video material. Extended format video material may be stored in the video source 21 . At this time, the decoding server 12 may be omitted. The editing server 11 is connected in communication with the video source 21 . The editing server 11 is configured to obtain dual-format encoded video material from the video source 21 based on the to-be-obtained video identifier and the basic format standard, and decode the dual-format encoded video material to obtain a corresponding basic format standard that meets the , as the video material to be edited. After the editing server 11 obtains the video material to be edited, the subsequent processing process is the same as that in the foregoing embodiment, and is not repeated here for the sake of brevity of the description. The composition server 13 is configured to obtain the dual-format encoded video material from the video source 21 according to the identifier of the video material to be edited, and restore the original video material based on the dual-format encoded video material (including the extended format video material and the basic format video material) , and then package the original video material (for example, rendering, compositing, etc.) according to the timeline file and the timeline position to generate a delivery file. In this way, after the editing server 11 obtains the video material that meets the basic format standard, it only needs to perform a decoding operation to obtain the video material to be edited. A decoding operation is required to restore the original video material based on the double-format encoded video material. Therefore, neither the editing server 11 nor the synthesizing server 13 has high performance requirements.
