Problems solved by technology

It cannot be accurate to the frame level, and the ideal effect cannot be achieved in production
[0004] If you want the filter effect to be different for each frame when making a video, or intersperse a few paragraphs of plain text descriptions, or add a few beautiful pictures, or insert a few wonderful clips, or add a few classic songs as background music, The traditional method is cumbersome, and it is impossible to flexibly allocate any combination of materials on the time axis. These functions will be realized through multiple transcoding, which will greatly reduce performance.

Embodiment 1

[0049] Before the cloud clipping method proposed by the present invention is described in detail, the following technical terms are introduced first:

[0050] A frame is the smallest unit of a single video frame in video animation, which is equivalent to each frame on a movie film. One frame is a still picture, and continuous frames form an animation.

[0051] Video encoding is encoded according to GOP (Group of Pictures, Group of Pictures). A GOP file is a group of continuous pictures (ie frames). Each GOP file represents the distance between two I frames. There is no connection between GOPs. of.

[0052] In compression coding, a picture can be divided into three types of frames: I, P, and B. I is an intra-coded frame, P is a forward prediction frame, and B is a bidirectional interpolation frame. Simply put, I frame is a complete picture, while P frame and B frame record changes relative to I frame, without I frame, P frame and B frame cannot be decoded. figure 1 A GOP comp...

Embodiment 2

[0097] The above embodiments describe the cloud editing method of the present invention in detail, and the cloud editing device of the present invention will be described in detail below from the perspective of modular functional entities.

[0098] Please see Figure 8 , the cloud clipping device provided in this embodiment includes:

[0099] Interface module 1, used to encapsulate the basic transcoding module in the cloud clipping server, and provide a video editing interface for clipping services;

[0100] The clipping module 2 is used for the cloud clipping server to analyze the clipping instruction and execute the clipping task after receiving the clipping instruction and the clipping material sent by the user, and perform video clipping in units of frames; the clipping instruction includes video screenshot, video interception, video filter and Multi-material mix;

[0101] The output module 3 is used for the cloud clipping server to encode and package the video that comp...

Embodiment 3

[0105] Please see Figure 10 , the cloud clipping device 500 may have relatively large differences due to different configurations or performances, and may include one or more processors (central processing units, CPU) 510 (for example, one or more processors) and memory 520, a Or more than one storage medium 530 (such as one or more mass storage devices) for storing application programs 533 or data 532 . Wherein, the memory 520 and the storage medium 530 may be temporary storage or persistent storage. The program stored in the storage medium 530 may include one or more modules (not shown in the figure), and each module may include a series of instruction operations on the cloud clipping device 500 .

[0106] Further, the processor 510 may be configured to communicate with the storage medium 530, and execute a series of instruction operations in the storage medium 530 on the cloud clipping device 500.

[0107] The cloud clipping device 500 may also include one or more power ...

Abstract

The invention discloses a cloud editing method, device and equipment and a storage medium, and aims to solve the problem that the video effect is reduced due to the fact that a conventional video editing method usually performs processing according to a second level and cannot achieve the precision to a frame level, a basic transcoding module is packaged in a cloud editing server, and a video editing interface oriented to editing service is provided. After the cloud shear server receives the editing instruction and the editing material sent by the user, the cloud shear server analyzes the editing instruction and executes an editing task, video editing is carried out by taking a frame as a unit, the operation precision of video capture, video screenshot, video filter and the like reaches aframe level, and the video production effect is improved.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a cloud editing method, device, equipment and storage medium. Background technique [0002] A new era of personal video has arrived, one in which you can sit in front of your home computer and create studio-quality movies, creating a stunning presentation video. [0003] The video frame interval is at the millisecond level. Traditional video splitting, screenshots, and filter effects are processed at the second level. If the frame rate is 25 frames per second, the blur position is 25 frames. If the positioned frame is not an I frame , the positional deviation is larger. It cannot be accurate to the frame level, and the ideal effect cannot be achieved in production. [0004] If you want the filter effect to be different for each frame when making a video, or intersperse a few paragraphs of plain text descriptions, or add a few beautiful pictures, or insert a...
