Detailed ways

The present application will be further described in 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 related invention, but not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

FIG. 1 illustrates an exemplary system architecture 100 to which embodiments of the special effects video generation method of the present application may be applied.

As shown in FIG. 1 , the system architecture 100 may include devices 101 , 102 , 103 , 104 and a network 105 . The network 105 is the medium used to provide communication links between the devices 101 , 102 , 103 , 104 . The network 105 may include various connection types, such as wired, wireless target communication links, or fiber optic cables, among others.

The devices 101, 102, 103, 104 may be hardware devices or software that support network connections to provide various network services. When the device is hardware, it can be a variety of electronic devices including, but not limited to, smartphones, tablet computers, laptop computers, desktop computers, servers, and the like. At this time, as a hardware device, it can be implemented as a distributed device group composed of multiple devices, or can be implemented as a single device. When the device is software, it can be installed in the electronic devices listed above. At this time, as software, it may be implemented as a plurality of software or software modules for providing distributed services, or may be implemented as a single software or software module. There is no specific limitation here.

In practice, the device can provide corresponding network services by installing a corresponding client application or server application. After the client application is installed on the device, it can be embodied as a client in network communication. Correspondingly, after the server application is installed, it can be embodied as a server in network communication.

As an example, in FIG. 1, the devices 101, 102, 103 are embodied as terminals, and the device 104 is embodied as a server. Specifically, the devices 101, 102, and 103 may be clients that actually install the target files, and 104 may be based on the clients that provide shredded special effects videos for the target files.

In practice, since generating a smashing special effect video according to the current display content of the target file does not require much computing resources and strong computing power, in order to consider the convenience of the user to play the smashing special effect video when the target file is smashed in the future, Therefore, the special effect video generation methods provided by the subsequent embodiments of the present application are generally executed by the devices 101 , 102 , and 103 installed with the target files. In this case, the exemplary system architecture 100 may also not include the device 104 and network 105 embodied as a server.

However, it should also be pointed out that, for example, when the computing power of the devices 101, 102, and 103 is insufficient, or it is preferable to perform the special effect video generation work at the device 104 embodied as a server (for example, the service provider provides the user with a crushing special effect video service). When there are many computing resources required to generate a smashing special effect video, etc.), the device 104 can also complete the above-mentioned operations performed by the devices 101, 102, and 103 through the corresponding applications installed on it, and then output the output with the devices 101, 102, and 103. 102 and 103 have the same result. Especially when there are multiple terminal devices with different computing capabilities at the same time, but the device 104 where the corresponding application determines that the device 104 is located has stronger computing capabilities and more remaining computing resources, so as to generate special effects videos more efficiently, The device 104 can be allowed to perform the above operations, so as to appropriately reduce the computing pressure of the devices 101 , 102 , and 103 .

It should be understood that the number of networks and devices in Figure 1 is merely illustrative. There can be any number of networks and devices depending on the implementation needs.

Please refer to FIG. 2, which is a flowchart of a special effect video generation provided by an embodiment of the present application, wherein the process 200 includes the following steps:

Step 201: Obtain the current display content of the target file, and generate a bitmap of the current display content.

In this embodiment, the execution body of the special effect video generation (for example, the devices 101, 102, 103 shown in FIG. 1 that are embodied as terminals) acquires the current display content of the target file, and generates a corresponding bitmap (Bitmap) based on the current display content. ), also known as raster graphics or bitmap, is an image represented by a pixel array (Pixel-array/Dot-matrix).

Wherein, when the target file is closed, the current display content may be the display icon and the corresponding file name of the target file, or may be the display content of a specific page in the target file, such as the first page after opening the target file, The tab page of the target file specified by the user, etc.

It should be pointed out that the current display content of the target file can be directly obtained by the above-mentioned execution body from a local storage device, and the local storage device can be a data storage module arranged in the above-mentioned execution body, such as a server hard disk, in this case , the current display content of the target file can be quickly read locally.

In addition, when the above-mentioned execution body generates special effects videos for other devices, the current display content of the target file may also be obtained from a non-local storage device (eg, the device 104 shown in FIG. 1 ). The non-local storage device may also be Any other electronic device configured to store data, such as some user terminals, in this case, the above-mentioned executive body can obtain the current display content of the desired target file by sending an obtaining command to the electronic device.

In practice, in order to better reflect the effect of the currently displayed content of the target file, the size of the bitmap is preferably the same as the definition and size of the currently displayed content, so that the subsequently generated special effect video content is relatively relative to the currently displayed content , showing better results.

Step 202: Store the pixel value of the pixel in the bitmap into the collision data set, and set the size of the pixel to change with time within a preset time period.

In this embodiment, after obtaining the bitmap based on the above step 201, the pixel value of each pixel in the bitmap is stored in the collision data set (Crashdata), and the pixel value at least includes size information, Each component element in the collision data set records the size information and color information of the pixel point, and after the pixel point value is stored in the collision data set, the corresponding size information in the value change of the pixel point is set in the preset value. The time period varies with the size of the time.

Among them, the length of the preset time period usually corresponds to the deletion process of the target file, that is, the time when the action starts according to the desired pixel point is the start, and the time when the deletion of the target file is completed is the end, and the corresponding preset time period is determined. On this basis, it is also possible to set different preset time periods for different pixel points according to the special effect that is expected to be achieved, so as to combine to form the above-mentioned special effect that is expected to be achieved.

In some embodiments, the color information in the pixel value can also be synchronously set to change with the size within a preset time period, so as to further enrich the diversity of the smashing special effect video.

Exemplarily, when the representation of the collision data set is formed as a matrix, each data in the collision data set matrix corresponds to a value unit of a pixel, and this value unit has a color value, and the pixel is in the bitmap. The x-coordinate and y-coordinate form a matrix based on the value units of each pixel in the bitmap to obtain a collision data set.

Step 203 , generating a rendered image based on the collision data set, and generating a smashing special effect video of the target file according to a plurality of rendered images whose generation time is continuous.

In this embodiment, after the collision data set is obtained based on the above step 202, because the size of the pixels recorded in the collision data set changes with time within a preset time period, the pixel points recorded in the collision data set are continuously Value rendering generates a corresponding image, and arranges the acquired images according to the generation time to obtain an image sequence, and generates a smashing special effect video formed based on the change of pixel size according to the image sequence.

In the special effect video generation method provided by the embodiment of the present application, the current display content of the target file is acquired, a bitmap of the current display content is generated, the pixel values of the pixel points in the bitmap are stored in the collision data set, and set in a preset It is assumed that the size of the pixel in the time period changes with time, a rendered image is generated based on the collision data set, and a smashing special effect video of the target file is generated according to multiple rendered images with continuous generation time. This embodiment can generate a shredding special effect based on the currently displayed content in the target file, so that the shredding effect video can be played later when the target file is shredded, which can not only help the user understand the shredding state of the file, but also enhance the interaction of the file shredding process. enhance the user experience.

In some embodiments, storing the value of the pixel in the bitmap into the collision data set includes: dividing the pixel in the bitmap into a preset number of sub-pixels; The point value is stored in the collision dataset.

Specifically, when the pixels in the bitmap are stored in the collision data set, the pixels in the bitmap can be further divided into a preset number of sub-pixels, and the shape of the sub-pixels can be determined as The circle corresponding to the pixel point can also be determined as a diamond, triangle, etc. according to actual needs, and further store the pixel value of each sub-pixel point in the collision data set to improve the special effect detail in the smashing special effect video. granularity.

In some embodiments, setting the size of the pixel to change with time within a preset time period includes: in response to storing the value of the pixel, a pixel having at least one historical pixel already exists in the collision data set Value, the end time of the size change of the historical pixel point is taken as the start time of the size change of the value of the pixel point.

Specifically, when the pixel value of the pixel is stored in the collision data set, the pixel value of the historical pixel that has been stored in the history already exists in the collision data set, and the size of the historical pixel value is obtained. The time when the size changes over time, and the end time is used as the starting time for the size change of the stored pixel value, so as to continue the current stored pixel when the size of the historical pixel is changed. Point size changes for more dynamic effects.

In some embodiments, using the size change end time of the historical pixel point as the size change start time of the pixel point value includes: storing the size change end time from the pixel point value to the nearest historical pixel value storage time The change end time of the pixel value of the point is taken as the start time of the size change of the pixel value.

Specifically, determine the time when the pixel value of the historical pixel point is stored in the collision data set, and take the time when the size of the value of the historical pixel point with the nearest storage time changes over time and ends as the pixel value stored this time. The starting time of the size change of the value, to further improve the continuity of each part in the effect.

In some embodiments, the method for generating the special effect video further includes: in response to the number of pixels in the collision data set whose size changes within the same preset time period meeting a preset requirement, updating the preset time period .

Specifically, when the number of pixels whose size changes based on the same preset time period are set in the collision data set to meet the preset requirements, the preset time period is updated, and the subsequent pixels are updated with the updated preset time. The corresponding setting of the size change of the point is performed to realize the gradient setting of the size change of the pixel point and form more kinds of special effects.

In some embodiments, the pixel value of the pixel in the bitmap is stored in the collision data set, and the size of the pixel is set to change with time within a preset time period, including: the pixel in the bitmap is The pixel value of the point is stored in the collision data set, and the size of the pixel is obtained; the change speed is determined according to the size, and the size of the pixel is set to change with time according to the change speed within the preset time period .

Specifically, when the pixel value of the pixel in the bitmap is stored in the collision data set, the size of the pixel is obtained, and the corresponding change speed is determined according to the size, and the pixel is set within a preset time period. The size of the point changes with time according to the change speed, so as to generate special effects suitable for the resolution of the current display content and improve the visual effect.

Further, on the basis of any of the above-mentioned embodiments, in order to fully make the special effect video obtained according to the above-mentioned special effect video generation method play a role, it can also be made to play a role in the file shredding scene according to the following steps:

In response to receiving the shredding instruction sent for the target file, a file shredding operation is performed on the target file, and a shredding special effect video corresponding to the target file is played; wherein, the shredding special effect video is generated by the special effect video generation method provided in FIG. 2 . generate.

Referring to FIG. 3 on this basis, a flow 300 of an embodiment of a special effect video playback method is shown, which specifically includes:

Step 301, in response to receiving the shredding instruction sent for the target file, perform a file shredding operation on the target file.

In this embodiment, the device actually installed with the target file is usually used as the execution body of the special effect video playback method (for example, the devices 101, 102, 103 shown in FIG. After the shredding instruction sent by the file, the shredding special effect video generated locally in advance can be obtained and played accordingly, or the shredding special effect video of the desired target file can be obtained by sending an acquisition command to other devices for generating shredding effect video.

In step 302, the interface is jumped to the display interface where the activation logo of the target file is located, and the transparency of the activation logo is lowered.

In this embodiment, after starting to execute the shredding instruction sent by the target file, the interface of the device that saves the target file is jumped to the display interface where the startup identifier of the target file is located, which can be exemplified by the startup identifier of the target file. on the desktop, application menu, etc., and reduce the transparency of the startup logo in the display interface.

In some embodiments, if the shredding instruction sent for the target file explicitly specifies that the shredding target is part of the data in the target file, the activation identifier may be determined to be the activation identifier for retrieving the partial data in the target file, and correspondingly The interface jumps to the interface where the startup identifier of the part of the data is recorded in the target file.

In some embodiments, in order to better present the display effect of the smashing special effect video, the transparency of all the startup signs included in the display interface may be further lowered.

Step 303: Play the smashing special effect video corresponding to the target file on the lower interface of the display interface where the start-up identifier of the target file is located.

In this embodiment, the smashing special effect video corresponding to the target file is played on the lower interface of the display interface where the startup logo is located, so as to simultaneously present the target file and the corresponding smashing special effect video on the device.

In the special effect video playback method provided in this embodiment, when the target file is deleted, the smashed special effect video corresponding to the target file can be played synchronously, which can not only help the user to understand the shredding state of the file, but also enhance the performance of the file shredding process. Interactive, enhanced user experience.

In some embodiments, the method further includes: updating the currently displayed content according to the deletion progress of the target file; obtaining an updated shredding special effect video based on the updated current display content; and playing the shredding corresponding to the target file Special effects video, including: Play the update smash special effect video.

Specifically, when the above-mentioned execution body performs the smashing operation of the target file and plays the smashing special effect video, the currently displayed content may further be updated according to the deletion progress of the target file. Exemplarily, when the smashing progress reaches 50%, the Crop the display content to 50% of the original image, obtain the updated current display content, and give feedback on the updated current display content, so that the execution subject of the special effect video generation method can crush the special effect according to the updated current display content. The video is updated to better feedback the crushing progress into the crushing effect video, so as to generate a more dynamic and more valuable crushing effect video.

In order to deepen understanding, this application also provides a specific implementation scheme in combination with a specific application scenario:

1) In this application scenario, the main body of the special effect video generation method obtains the current display content of the target file (a sketch of a house), as shown in Figure 4-1, and generates a bitmap of the current display content .

2) Store the pixel value of the pixel point in the bitmap at least including the size information into the collision data set, and set the size of the pixel point within the preset time period to become 0.5 times larger for every 1 second increase (ie The size of the pixel point x, y coordinates, magnified 0.5 times per second).

3) Generate a rendered image based on the collision data set, and generate a smashing special effect video of the target file according to a plurality of rendering images whose generation time is continuous, wherein, a schematic diagram of a rendered image effect for generating this smashing special effect video can refer to FIG. 4 -2.

In this application scenario, the execution body of the special effect video generation method can generate a corresponding bitmap according to the current display content of the target file, and store the pixel values of the pixel points in the bitmap into the collision data set, and then control the collision data set. The elements change with time, that is, the pixels in the bitmap are gradually changed with time to generate special effects in which the pixels in the bitmap are gradually expanded, to simulate the special effects of the target file being gradually smashed, and obtain the final smashed special effects video, so as to facilitate When the target file is shredded subsequently, the shredding special effect video is played, which can not only help the user understand the shredding state of the file, but also enhance the interactivity and user experience of the file shredding process.
