With the development of internet technology, the threshold of video production and processing is lower and lower, and more users enter the field of video production. For users who need to process videos on a large scale, such as new media practitioners, processing of stickers for each video requires a great deal of time and effort. In order to improve convenience and efficiency of video production, some users may design template files in advance, where the template files include preset materials, rendering modes, and the like.

As shown in fig. 1, for convenience of description, the present embodiment provides a video production method, which is described by using a common server as an execution subject, where the server may be replaced by a tablet, a computer, or another device with a data processing function, and the video production method includes the following steps:
and S10, acquiring a video production instruction.
Specifically, the server obtains a video production instruction first, and the user can specify a plurality of video materials in the video production instruction. The video production instruction specifies template information for producing a video file, such as a template number and a template name.
And S20, determining a template file corresponding to the video making instruction according to the video making instruction.
Specifically, after the video production instruction is obtained, a template file corresponding to the video production instruction in the pre-stored template files is determined according to template information in the video production instruction.
The template file is a pre-prepared template file for making videos, canvas attribute values, sticker materials, sticker coordinates and transformation attribute values can be preset in the template file, and the sticker coordinates comprise preset coordinates corresponding to the preset stickers.
As shown in fig. 2, the canvas attribute value is an attribute value such as the size of the canvas used for generation, the background color, and the like, and the canvas size is, for example, 720 × 1280. The sticker material comprises a preset sticker and an update sticker, wherein the preset sticker refers to a sticker carried by the template file during creation, such as a sticker set by a designer of the template file, and the update sticker is a sticker subsequently updated by a user or the designer. Since the preset sticker is the sticker set when the template file is created, it has corresponding preset coordinates, i.e., the position coordinates of the preset sticker on the canvas. If the sticker material is directly pasted on the canvas, the pasting effect is relatively stiff, so that the general sticker material needs to be subjected to conversion processing such as rotation and scaling, the pasting effect is more flexible, and the conversion attribute value refers to the conversion mode and the conversion parameter adopted by the sticker material.
The update sticker includes stickers from different sources, for example where the update sticker includes a user sticker derived from sticker material uploaded by a user. The video production instruction can comprise user materials, the user uploads the user materials while sending the video production instruction, and the server takes the user materials as the updating sticker corresponding to the template information in the video production instruction and stores the updating sticker. Because the user's material that the user sent generally all is screenshot or simple drawing, and the highlight degree and the effect that directly regard as the sticker are relatively poor, consequently, for the highlight degree that improves the sticker material, when uploading user's material, can carry out special effect to the user's material, concrete mode is:
and A10, displaying a preset special effect selection box when the user material is detected.
Specifically, when it is detected that a video production instruction contains a user material, a preset special effect frame is displayed, and the special effect frame contains various different processing names and corresponding processing parameters, such as clipping, noise reduction, cutout and the like. For example, the special effect box includes general processing options and special processing options, the general processing options include general processing such as image denoising, high definition processing, cropping, and rotation, and the special effect processing options include special effect processing such as matting, image stylization, and face transition. The user material can be stored in the user material module and enter the server for Operation, and the server can adopt OSS (Operation Support Systems).
And A20, when a special effect instruction corresponding to the special effect selection frame is detected, carrying out special effect processing on the user material according to the special effect instruction to obtain a special effect paster and displaying the special effect paster.
Specifically, the user sends a special effect instruction according to the content selected by the special effect box. And when the special effect instruction is detected, carrying out special effect processing on the user material according to the special effect name and the processing parameter in the special effect selection frame aimed at by the special effect instruction. And displaying the special effect paster obtained by the special effect processing on a display screen so that a user can select the special effect paster which accords with the mind of the user.
For example, the uploaded user materials contain faces, the selected special effect processing is juvenile, face recognition is conducted on the user materials, face images in the user materials are extracted, and then the face images are juvenile based on a juvenile model trained in advance to obtain the special effect paster. For another example, the user materials include a plurality of user materials, the selected special effect is processed into an excessive video, the face images of the uploaded user materials are respectively extracted, then the appointed user materials are used as initial images, face replacement images of the initial images are made unexpectedly, and then the special effect paster is made according to the initial images and the face replacement images. For example, the uploaded user materials include user material a, user material B, and user material C, and the starting image is user material a. And replacing the face image in the user material B and the face image in the user material C with the face image in the user material A to respectively obtain a face replacement image B and a face replacement image C, and then making the initial image, the face replacement image B and the face replacement image C into a moving image to obtain the special effect sticker.
In addition, all special effect stickers may be clipped to a fixed size, e.g., 100 x 100, for size uniformity.
In addition, in order to increase the processing rate, the embodiment performs the special effect processing and the presentation in an asynchronous processing manner. Taking the user material A, B as an example, the user material a is displayed after being processed, and the user material B is processed while being displayed. The special effects processing may be performed by the material processing module.
And A30, when a determination instruction corresponding to the special effect paster is detected, saving the special effect paster corresponding to the determination instruction as the user paster corresponding to the template file.
Specifically, when the user determines the special effect sticker meeting the mind of the user, a determination instruction for the special effect sticker is sent, and the special effect sticker corresponding to the determination instruction is used as the user sticker corresponding to the template file and is stored. The special effect sticker may be stored in a user library module.
For the preset sticker in the template file selected by the user and the user sticker uploaded by the user, the preference of the user to the sticker and the positioning of the style of the template file are suggested, for example, the preset sticker and the user post are both in an lovely style, and the user has a preference to the sticker in the lovely style, so that for each template file, the user can be imaged according to the user sticker and the preset sticker corresponding to the template file to obtain a user label corresponding to the template file, and the user label can be calculated in a mode of data statistics, clustering, theme and the like.
As shown in fig. 3, the user can upload user material, view video production effect, and the like, and the user experience function entry module can be used to implement the method.
Besides manual uploading of the pasters by users, in order to improve the richness of the pasters, the pasters are buried in databases such as a material library in advance, and pasters are obtained from the material library regularly in a point burying mode. The method specifically comprises the following steps:
and B10, acquiring the buried point material based on a preset updating instruction.
Specifically, an update instruction is preset, the instruction is used for updating the sticker material, and the update instruction includes information such as an update cycle and an update number. The method can be used for embedding points in a database for storing materials in advance, when the situation that new materials for manufacturing stickers are updated is detected, new materials are obtained from the database based on an updating instruction and are stored into the database as embedded point materials, and the database can be named as an embedded point material management module.
And B20, screening the point burying materials according to preset screening rules to obtain the point burying paster.
Specifically, in order to avoid the excessive number of the embedded point stickers, a screening rule is preset in this embodiment, and is used for screening the embedded point materials to obtain the embedded point stickers. In one way of filtering the rules, the number of the embedded point stickers is set, for example 10, and only the top 10 acquired embedded point materials can be used as the embedded point stickers. In another screening rule, the embedded point materials are compared with the preset pasters, the embedded point materials which are very close to the preset pasters are removed from the embedded point pasters, the repeated appearance of the pasters with high similarity is avoided, and the richness of the pasters is increased inefficiently.
In order to cope with the preferences of different users, the third filtering method is also performed in combination with the previous user tags. Firstly, performing feature recognition on the buried point material to obtain buried point features, wherein the buried point features can be text descriptions, tags, feature vectors and the like of the buried point material. And calculating the similarity value between each buried point feature and the user tag, wherein the similarity can be calculated by adopting a cosine similarity algorithm. And finally, determining the embedded point paster in the embedded point material according to the similarity value. And presetting a similarity threshold, and taking the embedded point material with the similarity value exceeding the similarity threshold as the embedded point material close to the user label, namely the embedded point sticker. The third screening method can also be associated with a fixed number, for example, the number of the newly added stickers at one time is preset, that is, the threshold value of the newly added number is less than or equal to 10, and the top 10 of the embedded point materials are selected as the embedded point stickers from the embedded point materials exceeding the similarity threshold value. The added quantity threshold value can be determined according to the canvas attribute value, the number of the preset stickers and the user stickers in the template file. Taking the example that the preset sticker and the user sticker are both empty, the canvas attribute value 700 × 1280 can accommodate 700 × 1280/100 × 100=89 stickers for a sticker size of 100 × 100, and the newly added threshold value is a value smaller than 89, for example, 80. The screening aiming at the user preference can be realized by adopting a recommendation service module.
And S30, creating a blank canvas according to the canvas attribute value, and calculating a chartlet coordinate corresponding to the preset pasters according to the preset coordinate and the transformation attribute value.
Specifically, a blank canvas corresponding to the threshold is created according to the canvas attribute value, and in this embodiment, the size of the blank canvas is 720 × 1280.
Meanwhile, for the preset sticker, because the preset sticker is not directly pasted on a blank canvas, generally, the preset sticker is processed by rotating, amplifying, reducing and the like, the corresponding pasting coordinate is calculated according to the preset coordinate and the transformation attribute value set by the designer of the template file.
For example, a canvas coordinate system is constructed by presetting a vertex at the upper left corner of the canvas coordinate as an origin, a horizontal axis at the left side and a vertical axis at the upper side. The preset coordinates corresponding to the preset sticker are (0,0), (0, 100), (100,0) and (100 ), the anchor point is (50, 50), the anchor point refers to the center point coordinate of the rotation of the sticker material in the layer coordinate system, and the center point coordinate generally selects the midpoint of the sticker material. The transformation attribute values include image transformation parameters such as a rotation value, a scaling ratio, etc., wherein the rotation value is 30 ° counterclockwise and the scaling ratio is 0 in this example. The coordinates after rotation can be calculated according to the rotation formula and taken as mapping coordinates. For example, (0,0) corresponds to coordinates (-13, -32), (100 ) corresponds to coordinates (36, 136). The coordinate system of the canvas can be freely set, for example, in fig. 2, the upper left corner of the display interface is used as the origin, the horizontal left side is used as the horizontal axis, and the vertical downward side is used as the vertical axis.
If the transformed coordinates are directly used as the coordinates of the mapping, on one hand, the calculation in the mapping is complex, and on the other hand, the coordinates which are easy to be selected are overlapped with the preset paster when the coordinates are selected and updated subsequently, so that the calculation burden is increased. Therefore, in this embodiment, the mapping coordinates are calculated in the form of a bounding box, and first, for each of the preset pasters, the coordinates of the converted preset pasters are calculated according to the size of the pasters corresponding to the preset pasters and the transformed attribute values, and the coordinates are used as the insertion coordinates, for example, (36, 136) in the foregoing example, and the pseudo code used here can be referred to as shown in fig. 4. And then generating a minimum rectangular surrounding frame corresponding to the preset paster according to the inserting coordinates. The minimum rectangular bounding box refers to coordinates, a rectangle length and a width that surround the center of the set of specified contour points, as shown in fig. 2, the sides of the transformed preset sticker are not horizontal and vertical, and the minimum rectangular bounding box is a conventional rectangular box that can surround the transformed preset sticker. The algorithm of the minimum rectangular bounding box can adopt a rotating caliper algorithm, a traversal algorithm and the like. And finally, generating a map coordinate according to the minimum rectangular surrounding frame.
In the first way of generating the map coordinates, the coordinates inside the minimum rectangle bounding box can be directly taken as the map coordinates, which can be described by the four-corner coordinates and the anchor point. Since the template file is in different environments, the sticker material from different sources is prone to shift in coordinates to some extent, and the transformation will shift some of the sticker material away from the canvas, for example (-13, -32) as mentioned above, beyond the range displayed by the canvas. To avoid the effect of such an offset causing the final video to render only a portion of the sticker material, the present embodiment also corrects for the smallest rectangular bounding box. The method specifically comprises the following steps:
c31, determining whether the minimum Bao Weikuang is crossed with the canvas coordinate according to the minimum Bao Weikuang and the canvas coordinate of the blank canvas.
Specifically, the coordinates of the canvas, that is, the coordinates of the area displayed by the canvas on the canvas coordinate system, are compared with the coordinates of the canvas in the smallest bounding box to determine whether there is an intersection between the smallest Bao Weikuang and the canvas coordinates. Intersection herein should narrow the interpretation, referring only to the coordinates within the existing non-canvas coordinates in the smallest bounding box. The simple judgment method is to compare the vertex coordinates of the smallest enclosing frame with the vertex coordinates of the canvas coordinates.
And C32, if the minimum surrounding frame exists, calculating the moving distance between the surrounding frame coordinate of the minimum surrounding frame and the canvas coordinate.
Specifically, the bounding box coordinates of the smallest bounding box refer to the vertex coordinates of the smallest bounding box, the distance between each bounding box coordinate and the vertex in the canvas coordinate is calculated, the distance is used as a movement value, the positive direction of the canvas coordinate system is used as the movement direction, and the movement distance corresponding to each bounding box coordinate is calculated.
And C33, generating the map coordinate according to the moving distance.
Specifically, after the moving distance is obtained, all coordinates of the smallest enclosing frame are adjusted according to the moving distance to obtain the mapping coordinates.
And S40, determining an updating coordinate corresponding to the updating paster according to the mapping coordinate and the canvas attribute value.
In particular, the canvas attribute value determines the size of the canvas, and also determines the number of coordinates of the sticker on the canvas. All available coordinates on the canvas can be determined according to the canvas attribute values, all already occupied coordinates on the canvas can be determined according to the map coordinates, the rest coordinates are updated coordinates corresponding to the updated stickers, and the rest coordinates are called idle coordinates. And the free coordinates can be randomly distributed to the corresponding update coordinates of different update stickers.
The efficiency of adopting random allocation is too low, and overlapping easily occurs, so in this embodiment, a coordinate set may be generated according to the canvas attribute value first. In this example, the dimension is 720 x 1280, the outer-layer cyclic abscissa values are gradually increased by 1 from 0 and circulate to the maximum of 720, the inner-layer cyclic ordinate values are gradually increased by 1 from 0 and circulate to the maximum of 1280, and finally 720 x 1280 coordinate results are obtained, which are coordinate sets. If the coordinate set is represented by an array, it is [ (0,0), (0,1), (0,2),. - ]. And then screening the coordinate set based on the map coordinates to obtain idle coordinates. And then determining the updating coordinate corresponding to each updating paster according to the idle coordinate.
In order to avoid the situation of coordinate conflict when determining the update coordinates corresponding to the update sticker at the same time, the embodiment determines the update coordinates in a traversal manner. And traversing the updating stickers randomly, and determining the coordinates of each updating sticker until the traversal is finished. The coordinate determination is a process of determining the updated coordinate corresponding to the updated sticker. In one determination, random traversal is used, but space utilization is low. In another determination method, starting point coordinates are set in advance, for example, (0,0), and then initial coordinates are generated according to the starting point coordinates and the size of the updated seal paper, taking the coordinate system of the present embodiment as an example, the size of the seal paper is 100 × 100, and the initial coordinates are (0,0), (0, 100), (100,0), and (100 ). And then matching the idle coordinates according to the initial coordinates. And matching all coordinates in the range covered by the initial coordinates with the coordinate set, wherein if all the coordinates can be successfully matched with the idle coordinates in the idle set, the initial coordinate range does not contain the sticker material, so that the idle coordinates corresponding to the initial coordinates are used as the update coordinates corresponding to the update sticker, and the idle set is updated, for example, the idle coordinates corresponding to the update coordinates in the idle set are deleted.
As shown in FIG. 5, the set of canvas coordinates is named z, the free set is named z _ new, the set of map coordinates is named a2, the update sticker is represented by array a, i1 represents the coordinate in z, i2 represents the coordinate in a2, and i3 represents the coordinate in the array to which a2[ i2] points.
S50, inserting the sticker materials into the blank canvas according to the preset coordinates and the updated coordinates, and generating a target video.
Specifically, after the update coordinates are obtained, the preset sticker in the template file has the corresponding preset coordinates, and the update sticker has the corresponding update coordinates, so that the preset sticker can be inserted into the blank canvas according to the preset coordinates, and the update sticker can be inserted into the blank canvas according to the update coordinates, so that the target video is obtained. The user can upload a plurality of video materials at the moment, and the video materials are integrated and rendered based on the target video to obtain an edited video corresponding to each video material, so that the batch processing operation of the videos is completed. This operation may be implemented by the rendering service module.
Furthermore, after the sticker materials are inserted into the blank canvas, the user can adjust the coordinates corresponding to the sticker materials according to the preference of the user and change the shape, so that the effect of better meeting the mind of the user is achieved.
