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 ...
