The following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a schematic flowchart of a video creation method provided in an embodiment of the present application, and applied to an electronic device, the video creation method includes:
s201, when the electronic equipment detects a video creation request, the electronic equipment acquires a target theme of a video to be created, which is input by a user.
When a video creation request initiated by a user is detected, a target theme of a video to be created, which is input by the user, is acquired, and the electronic device can determine video data according to the target theme to create the video.
The video to be created can be an album recall video, a user can view the recall video through operations such as opening an album, the picture relevance degree in the recall video is high, the user can be reminded of recalling when shooting a target picture by viewing the recall video, a scene reappears, and the method is also a beautiful life recording mode.
S202, when detecting that video data with the same theme as the target theme is prestored in a cache space, the electronic device acquires the video data, wherein the cache space is a hidden space.
The video data corresponding to videos with different themes are stored in the cache space of the electronic device, the cache space is a hidden space, a user cannot check and does not know the existence of the cache space, and when the video data with the same theme as the target theme is detected in the pre-stored video data, the video data is acquired.
S203, the electronic equipment generates a target video corresponding to the target theme according to the video data. The video data can be generated data stored in the cache space or a set of multiple pictures used for generating videos, the target video can be quickly obtained according to the video data, therefore, the pictures are not required to be screened in the gallery according to the target theme input by the user, the recall video is generated by screening the multiple pictures, the processing time is shortened, and the recall video can be generated in a short time.
If the video data with the same theme as the target theme is not detected in the pre-stored video library, pictures related to the target theme need to be screened from the picture library to generate a target video, and the newly generated video is named by the target theme.
It can be seen that, in the embodiment of the present application, an electronic device first obtains a target theme of a video to be created, which is input by a user, when a video creation request is detected, and then obtains video data when video data with the same theme as the target theme is pre-stored in a cache space, where the cache space is a hidden space, and finally generates a target video corresponding to the target theme according to the video data. When the electronic equipment detects a video creation request, the electronic equipment can directly generate a video corresponding to a target theme according to the video data when detecting that the target theme input by a user is the same as the theme of the video data prestored in the cache space, and extract the video data from the cache space under the condition that the user does not perceive the video data so as to quickly generate the target video.
In one possible example, the video data includes a first set of pictures; the generating of the target video corresponding to the target theme according to the video data includes: acquiring a plurality of pictures associated with the target subject in a gallery; judging whether data updating occurs in comparison between the multiple pictures and the first picture set; when the data updating is detected to occur, determining data to be updated; and generating the target video according to the video data and the data to be updated.
Each picture in the first picture set is associated with the theme of the video data, and a plurality of pictures associated with the target theme in the picture library are obtained.
When it is detected that the data update occurs in the first picture set, that is, when pictures related to the target subject are added in the picture library but not in the first picture set, it is determined that the picture data corresponding to the part of the pictures are data to be updated.
As can be seen, in this example, the video data corresponds to the first picture set, and the target video may be generated directly according to the first picture set, but before the target video is generated, it is determined whether there are multiple pictures associated with the target topic in the gallery, and when the multiple pictures are not in the first picture set, it indicates that data update has occurred, and data to be updated needs to be determined, so that the video data is updated, which is beneficial to improving reliability and integrity of the target video.
In one possible example, the determining whether the data update occurs in the plurality of pictures compared to the first picture set includes: determining a creation time of the first picture set; determining that data update occurs when it is detected that there is a picture whose shooting time is after the creation time among the plurality of pictures.
The method comprises the steps of determining the creation time of a first picture set, namely the creation time of video data, and when judging whether data updating occurs in comparison between the multiple pictures and the first picture set, only determining whether pictures with shooting time after the creation time exist in the multiple pictures, and if so, indicating that the data updating occurs.
It can be seen that, in this example, the video data is pre-stored in the cache space of the electronic device, and the video data corresponds to the creation time, and if there is a picture with a shooting time after the creation time in the plurality of pictures, it indicates that data update has occurred, and the video data needs to be updated, so that the real-time performance and reliability of the video data are improved.
In one possible example, the determining data to be updated includes: selecting at least one picture with the shooting time after the creation time from the plurality of pictures; acquiring characteristic information of each picture in the at least one picture; determining the association degree of each picture and the target theme according to the characteristic information; selecting a picture with the association degree larger than a preset threshold value as a picture to be updated; and determining the data corresponding to the picture to be updated as the data to be updated.
The method comprises the steps of selecting at least one picture with shooting time after the creation time from a plurality of pictures, and obtaining feature information of each picture in the at least one picture, wherein the feature information can comprise at least one of shooting place information, shooting time information, face number information, person clothing information and picture color information.
The association degree between each picture and the target theme can be further determined according to the characteristic information, for example, the target theme is graduation season, and the association degree between the picture and the target theme can be determined according to whether the shooting place is school, whether the shooting time is in the time period of the graduation season, whether people and clothes wear scholars and school uniforms and other elements.
After the association degree of each picture and the target theme is determined, the picture with the association degree larger than a preset threshold value is selected as the picture to be updated, namely the data corresponding to the picture to be updated can be determined as the data to be updated, and after the data to be updated is determined, the target video is generated according to the data to be updated and the video data.
The data to be updated can be added to the video data, and the data to be updated can also be used for replacing part of data in the target video, so that when a user creates a video, the user can directly and quickly generate the target video according to the updated video data.
As can be seen, in this example, at least one picture of the plurality of pictures after the creation time is selected, and the association degree between each picture and the target theme is determined according to the feature information of each picture of the at least one picture, so that a picture with the association degree greater than a preset threshold value can be selected as a picture to be updated, and further data to be updated is determined.
In one possible example, the determining data to be updated includes: selecting at least one picture with the shooting time after the creation time from the plurality of pictures; acquiring characteristic information of each picture in the at least one picture; determining the association degree of each picture and the target theme according to the characteristic information; selecting a preset number of pictures with the highest relevance as pictures to be updated; and determining the data corresponding to the picture to be updated as the data to be updated.
The pictures in the first picture set are a plurality of screened pictures related to the target theme, so that the association degree between each picture in the first picture set and the target theme can be prestored, and the association degree between each picture in at least one picture and the target theme is determined, so that a preset number of pictures with the highest association degree are selected from the plurality of pictures as the pictures to be updated, and the association degree of each picture in the selected pictures to be updated is greater than the preset number of pictures with the lowest association degree in the first picture set.
For example, 5 pictures a2, B2, C2, D2 and E2 with the highest relevance are selected from at least one picture, and the relevance of the five pictures is greater than the 5 pictures a1, B1, C1, D1 and E1 with the lowest relevance in the first picture set, that is, the relevance is sorted as a2> B2> C2> D2> E2> a1> B1> C1> D1> E1, so that the pictures to be updated are determined to be a2, B2, C2, D2 and E2, that is, the pictures a2, B2, C2, D2 and E2 in the second picture set are used to replace the pictures a1, B1, C1, D1 and E1 in the first picture set.
As can be seen, in this example, according to the association degree between each picture in the first picture set and the target topic and the association degree between each picture in the at least one picture and the target topic, the picture to be updated is determined and the picture to be updated is used to replace the same number of pictures in the first picture set, which is equivalent to improving the association degree between the whole target video and the target topic, and the reliability is higher.
In one possible example, the generating the target video from the video data includes: determining the shooting time of the picture to be updated and a plurality of pictures in the first picture set; sequencing the plurality of pictures according to the sequence of the shooting time; and determining the sequence as the playing sequence of the plurality of pictures in a target video, wherein the target video sequentially shows the plurality of pictures within a preset time length according to the sequence.
The method comprises the steps of determining the shooting time of each picture in the pictures to be updated, sequencing the pictures to be updated according to the sequence of the shooting time, updating the pictures to be updated into video data according to the sequencing to obtain updated video data, and displaying the pictures in sequence according to the shooting time of each picture when a target video obtained according to the data to be updated and the video data is played.
As can be seen, in this example, the generated target video is composed of two parts, that is, the video data and the data to be updated that are pre-stored in the cache space, and the shooting time of the picture corresponding to the data to be updated is later than the shooting time of the picture corresponding to the video data, so that a part of the target video can be generated according to the video data, and a complete target video is generated according to the data to be updated, which is beneficial to reducing the waiting time of a user.
In one possible example, after the target video corresponding to the target topic is generated according to the video data, the method further includes: deleting the video data stored in the cache space.
As can be seen, in this example, after the target video corresponding to the target theme is generated according to the video data, the electronic device may delete the video data pre-stored in the cache space, because the generated target video may be directly stored, and deleting the video data may release the storage space.
