Description
Technical Field
The invention relates to the technical field of data processing, in particular to a self-adaptive generation method, device and equipment of advertisement materials and a storage medium.
Background
In the advertising field, for advertising screens of different sizes, advertisers need to adjust the design elements of the advertisements in terms of position, size, etc. to achieve optimal effect delivery on the advertising screens of different sizes. However, most of these adjusted advertising materials of different sizes are highly similar. The more the size of the advertising screen is put, the more times the manual adjustment is required, and the more the workload is. For large brands of advertisers, they have specialized design teams that can better address the size adaptation problem. However, for most other advertisers, the ability and investment in material adaptation is limited, which in turn can affect the advertising effectiveness.
The invention patent CN114125500A provides a synthetic method and a delivery system of advertisement delivery video, which solve the problem that part of advertisers are difficult to manufacture advertisements. The method is to carry out overall equal ratio size adjustment on the video, and fill other areas of the screen by combining other advertisement parameters. However, the aspect ratio of the static background picture is required to be the same as the aspect ratio of the input, and the static background picture cannot be adaptively compatible with multiple sizes. Only the whole advertisement video is subjected to equal-ratio scaling, and the relative positions of elements in the advertisement video cannot be adaptively adjusted according to multiple sizes. The advertisement parameters need to be uploaded actively by the advertiser, multiple times for multiple sizes. Although the font, color, size and position parameters are considered for the characters, the rendering difference of the characters under different operating system environments is not considered, so that the problem that in the actual application process, the advertisement material is previewed by a user and the advertisement material which is actually rendered is slightly different is caused. Meanwhile, the problem that video duration and frame rate are different under a plurality of videos is not considered.

Specifically, in step S1, it is assumed that the user has been in a size ofThe advertisement material comprises a background picture B and other foreground design elements (including but not limited to characters, pictures and videos). The number of foreground design elements is not limited, but the video needs to be placed at the top layer, i.e., displayed on a layer of text or pictures. The background picture B needs to be placed at the bottom layer, i.e. displayed at the next layer of all foreground design elements.
Assuming that one new size isSize of background picture BAnd new sizeIs compared with the size of the (c):
in step S2, if the size of the background picture B is greater than or equal to the new sizeThe background picture B is scaled down in an equal ratio; if the size of the background picture B is smaller than the new sizePerforming super-resolution processing on the background picture B; after the background picture B is obtained and resized, the new size is just externally connectedBackground picture of (c)。

Picture of backgroundAnd performing jigsaw processing on the advertisement material and other foreground design elements except the video to generate a new background picture. Wherein, firstly, the jigsaw processing is carried out, and the front page is mainly considered under the condition of web useThe performance of the surface user machine is insufficient, and background service is generally delivered to render advertisement material pictures, particularly videos. In order to ensure consistent display effect on characters, the same fonts are generally imported by background service. If the user uses the custom fonts, the user custom fonts also need to be uploaded to the background server, and the workload is large.
Even if the font files are the same, the font rendering effect will be slightly different due to a certain difference between the front page and the background service running environment, especially in the case of operating system differences. WPS, for example, may be used in other operating systems such as MAC or Linux, but their font rendering may be slightly different, and there is still a problem that the effect of back-end rendering advertisement materials is inconsistent with the front-end page presentation.
Therefore, the invention provides the concept of jigsaw processing, which can be simply similar to the process of firstly carrying out screenshot on non-video materials on a front-end page. Specifically, the jigsaw process is based mainly on background picturesAnd other non-video foreground design elements, performing image fusion according to the layer and position relationship, wherein the transparency of each foreground design element is 0. Through the jigsaw processing operation, part of work for generating the multi-size advertisement materials can be transmitted to the front end page for execution, so that the workload of background service is effectively reduced, and the speed for rendering the final advertisement materials is further effectively improved. Meanwhile, the problem that the final rendered video results are inconsistent due to the difference of the display effect of the characters at the front end and the rear end can be avoided.
Further, the new background pictures are respectively processed according to the number of the videosCombining video to generate a new sizeThe new advertisement material with the size specifically comprises the following components:
s71: acquiring the number of videos in the advertisement material foreground design element;
s72: if it isVideo number is 0, and pictures are takenAs a new sizeCorresponding new advertisement materials;
s73: if the number of videos is 1, pictures are displayedAs a base map, combining video directly to generate new sizesCorresponding new advertisement materials;
s74: if the number of videos is greater than 1, taking the lowest frame rate of all videos as the final frame rate of the new advertisement material, taking the shortest time length of all videos as the final time length of the new advertisement material, further carrying out frame shrinking treatment on videos exceeding the final frame rate one by one, cutting off the videos exceeding the time length one by one, and then carrying out picture cutting-off treatment on the videos exceeding the time length one by oneAs a base map, combining all foreground design element videos to generate a new sizeCorresponding new advertising material.
Specifically, the method further performs frame shrinking processing on the video exceeding the final frame rate one by one, specifically includes:
s741: the current frame rate of the obtained video isThe target frame rate isWherein, the method comprises the steps of, wherein,；
s742: the number of frames per second to be adjusted isEvery otherA position, the frame corresponding to the position needs to be subjected to frame shrinking processing, wherein,representing a downward rounding;
s743: assume a certain frameThe frame shrinking process is needed, and the front and back frames are respectivelyAnd；
s744: frame is formedIs set toFront and rear two framesAndtransparency of (2) is；
