When the significance result exists and the significance result indicates that the area of significance is smaller than the threshold value F (for example, the material is a picture material of a camel in the desert, wherein the camel is the significance result), the electronic equipment judges that the view of the material is a significance perspective.

H. Landscape long shot

The electronic equipment determines the picture segmentation result of any material based on a semantic segmentation technology.

And when the picture segmentation result shows that the area of the material is larger than the threshold value G and is a preset target, the electronic equipment judges that the scene of the material is a landscape long shot.

The user interface 12' is basically the same as the interface layout of the user interface 12 shown in fig. 3B, and the specific implementation manner can be referred to the description of the user interface 12 shown in fig. 3B in the first embodiment, which is not described herein again. Unlike the user interface 12 shown in fig. 3B, the number of videos stored in the user interface 12 'is increased by 1, and thus, the user interface 12' in fig. 3R shows that the number of all photographs is increased from "182" to "183" and the number of videos is increased from "49" to "50".

After detecting that the user performs an operation such as clicking on the control 3021 in the user interface 12 ' shown in fig. 3R, the mobile phone may display the user interface 13 ' exemplarily shown in fig. 3S, where the user interface 13 ' is a display interface of pictures and videos in the mobile phone.

The user interface 13 has substantially the same interface layout as the user interface 13 shown in fig. 3C, and specific implementation manners can be described with reference to the user interface 13 shown in fig. 3C in the first embodiment, which is not described herein again. Similar to the user interface 13 shown in fig. 3C, since the whole of the pictures/videos stored in the user interface 13 'moves to the next, the first material displayed on the user interface 13' in fig. 3S is a newly generated video 3039 in chronological order from the near to the current time.

The handset may play the video 3039 upon detecting that the user performs an operation such as clicking on the video 3039 in the user interface 13' shown in fig. 3S.

In the embodiment of the application, each video template can correspond to one piece of music. In general, different video templates correspond to different music. The electronic equipment can default that the music corresponding to each video template is kept unchanged, and can also change the music corresponding to each video template based on the selection of the user, so that the electronic equipment can be flexibly set through the actual situation. The music may be preset for the electronic device or manually added by the user, which is not limited in the embodiment of the present application.

In one aspect, the video template is also related to mirror motion, speed, and transitions. In general, different video templates differ in at least one of mirror motion, speed, and transition, whether the music to which the video templates correspond is the same or not.

For music corresponding to any one video template, each piece of the music can match the set moving mirror, speed and transition. The moving mirror and the transition can be related to the type of the material, the moving mirror adopted by the video material and the moving mirror adopted by the picture material can be the same or different, and the transition adopted by the video material and the transition adopted by the picture material can be the same or different. In addition, video material can generally set play effects corresponding to speed.

Referring to fig. 4A-4J, fig. 4A-4J are schematic diagrams illustrating the effect of the picture element 3033 after mirror-moving.

The mobile phone stores the image material 3033 exemplarily shown in fig. 4A, wherein the image material 3033 can refer to the description of the embodiment in fig. 3C, which is not described herein again.

When the cell phone displays the picture pixel 3033 with a mirror effect moving diagonally, the cell phone can change from displaying the interface 11 exemplarily shown in fig. 4B to displaying the interface 12 exemplarily shown in fig. 4C, wherein the interface 11 is the region a1 of the picture material 3033, the interface 12 is the region a2 of the picture material 3033, and the region a1 and the region a2 are located at different positions of the picture material 3033.

Besides the mirror moving effect of diagonal movement, the electronic device can also adopt mirror moving effects of upward, leftward, rightward and the like, which is not limited in the embodiment of the application.

When the mobile phone displays the picture pixel 3033 with the enlarged moving mirror effect, the mobile phone can change from the interface 1 exemplarily shown in fig. 4B to the interface 13 exemplarily shown in fig. 4D, wherein the interface 11 is the area a1 of the picture material 3033, and the interface 13 is an enlarged view of the area a3 of the picture material 3033.

Besides the enlarged mirror movement effect, the electronic device can also adopt the zoomed mirror movement effect, which is not limited in the embodiment of the application.

In addition, when the picture material 20 is a portrait picture as exemplarily shown in fig. 4E, and the generated video is in the form of a banner, the electronic device may display the picture material 20 with a moving mirror effect moving from top to bottom. For example, the cell phone may change from displaying the interface 21 exemplarily shown in fig. 4F to displaying the interface 22 exemplarily shown in fig. 4G, where the interface 21 is the region b1 of the picture material 20, the interface 22 is the region b2 of the picture material 20, and the region b1 and the region b2 are located at different positions of the picture material 20. Alternatively, the shape of the region composed of the region b1 and the region b2 may be set to be square. If the picture material 20 includes a person, a face, etc., the electronic device may include as many regions as possible, which correspond to the person and the face in the material, by using the region b1 and the region b 2.

When the picture material 30 is a banner picture as exemplarily shown in fig. 4H and the generated video is a portrait picture, the electronic device may display the picture material 30 with a mirror-moving effect moving from left to right. For example, the cell phone may change from displaying the interface 31 exemplarily shown in fig. 4I to displaying the interface 32 exemplarily shown in fig. 4J, where the interface 31 is the region c1 of the picture material 30, the interface 32 is the region c2 of the picture material 303, and the region c1 and the region c2 are located at different positions of the picture material 30. Alternatively, the shape of the region composed of the region c1 and the region c2 may be set to be square. If the picture material 30 includes a person, a face, etc., the electronic device may include as many regions corresponding to the person and the face in the material as possible by using the region c1 and the region c 2.

Therefore, the method is beneficial to the maximization of the material display of the video generated by the electronic equipment, enriches the content of the video and ensures the movie feeling and the picture feeling brought by the video.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating the effects of different speeds of the video material 3038. For the video material 3038, reference may be made to the description of the embodiment in fig. 3C, which is not described herein again.

As shown in fig. 5, assuming that the video generated by the electronic device based on the material plays the video material 3038 in the time period t 0-t 1 and the time period t 2-t 3, and the time period t 2-t 3 is three times as long as the time period t 0-t 1, the electronic device plays the video material 3038 in the time period t 0-t 1 at three times as fast as the video material 3038 in the time period t 2-t 3.

It should be noted that the speed may include any ratio speed besides the triple speed, and this is not limited in the embodiment of the present application.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating the effect of transition between the picture material 3033 and the picture material 3032. The picture material 3033 and the picture material 3032 can refer to the description of the embodiment in fig. 3C, which is not described herein again.

As shown in fig. 6, assuming that the electronic device plays the picture material 3033 in the time period t4 to t5, plays the picture material 3032 in the time period t6 to t7, and the picture material 3033 transitions to the picture material 3032 with the transition effect of superimposing blur in the time period t5 to t6, the electronic device plays the picture material 3033 in the time period t4 to t5, plays the gradually enlarged picture material 3032 superimposed on the blur-processed picture material 3033 in the time period t5 to t6, and plays the picture material 3032 in the time period t6 to t7 based on the video generated by the material.

It should be noted that, in addition to the "superimposition blurring" effect, the transition may also include effects such as focus blurring, which is not limited in the embodiment of the present application.

Therefore, the electronic equipment can realize scene scheduling and lens scheduling of the material according to the set moving mirror, speed and transition.

Video templates, on the other hand, are associated with a genre type. Generally, no matter whether the music corresponding to the video template is the same or not, the corresponding scene types of the different types of video templates are different; and the video templates of the same type have the same corresponding scene type.

When the user selects the music corresponding to the default video template, the electronic equipment does not need to adjust the duration of each segment of the video template, so that the music click can be realized. When a user selects other music as music corresponding to the video template, the electronic device needs to perform beat detection on the music selected by the user to obtain the beat speed of the music selected by the user, then judges whether the duration of each segment of the video template is equal to the integral multiple of the obtained beat speed, and adjusts the duration of the segment of which the duration is not equal to the integral multiple of the obtained beat speed, so that the duration of each segment in the video template is the integral multiple of the beat speed.

For any piece of music, in the embodiment of the present application, a Beat detection method may be used to perform Beat detection on the music by using a BPM (Beat Per Minute, Beat number) method, so as to obtain a Beat rate (BPM), where the electronic device analyzes audio by using a Digital Signal Processing (DSP) method to obtain a Beat point of the music. A common algorithm divides the original audio into several segments, then obtains a frequency spectrum through fast fourier transform, and finally obtains a beat point of the music through filtering analysis based on sound energy.

It should be noted that the scene type corresponding to each segment in each video template is set in advance based on practical experience (for example, the user perceives the scene type corresponding to a single segment and the scene types corresponding to a plurality of continuous segments at certain positions to be strong).

For music corresponding to any one video template, in the embodiment of the present application, a beat point of the music may be used as a boundary, the whole music is divided into a plurality of segments, and each segment is matched with a set scene type.

Wherein each section is an integral multiple of the beat speed of the music, thereby realizing the music beat point of each section. It is understood that the beat of music is the beat or beat, which refers to the combination rule of the beat and the beat, and specifically refers to the total length of notes of each measure in the music score, and the notes may be, for example, half notes, quarter notes, eighth notes, etc. In general, a piece of music may be composed of a plurality of beats, and the beats of a piece of music are generally fixed.

It will be appreciated that the selection of material is random, and in practice there is a high probability that the material will not fully satisfy the genre set for each segment. Therefore, when the above problems occur, the electronic device can adjust the arrangement order of the materials in various ways.

In some embodiments, the electronic device may prioritize each segment. Among them, the high priority fragments may include but are not limited to: the beginning, chorus, ending or accent segments of the music. Furthermore, the electronic equipment can prioritize the scene type set by the segment meeting the high priority, the material corresponding to the scene type set by the segment meeting the high priority is placed in the segment meeting the high priority, and the remaining material is placed in the remaining segment according to the scene type set by the remaining segment, wherein the scene type of the remaining material and the scene type set by the remaining segment can be the same or different.

In other embodiments, the electronic device may preferentially meet the scene type set by the segment located at the front, place the material corresponding to the scene type set by the segment located at the front in the segment located at the front, and place the remaining material in the remaining segment according to the scene type set by the remaining segment, where the scene type of the remaining material and the scene type set by the remaining segment may be the same or different.

The electronic equipment can also preferentially meet the scene type set by the front-positioned segment in the rest segments.

For music corresponding to any one video template, in the embodiment of the present application, the whole music may be divided into a plurality of segments by taking the beat point of the music as a boundary, and the set scene types are matched for the plurality of continuous segments, and the scene types of the remaining segments may not be limited. Thus, the shot feeling and movie feeling of the generated video are enhanced. The plurality of continuous segments may be segments of the beginning, end, or refrain of the music.

Taking the example of dividing the scene types into the short scene, the medium scene, and the long scene exemplarily shown in fig. 7 as an example, the respective corresponding scene types of the plurality of consecutive segments are introduced. Wherein, A represents the corresponding view type of the close view, B represents the corresponding view type of the middle view, and C represents the corresponding view type of the long view.

For example, the scene types corresponding to 5 consecutive segments corresponding to the beginning and/or the end of the music may be CCCBA, respectively, so that the generated video has an overhanging effect at the beginning portion or has an incomplete effect at the end portion.

As another example, the scene types corresponding to the 4 consecutive segments corresponding to the beginning and/or the end of the music may be ABBC, respectively, so that the generated video is an effect of preparing for video expansion narration at the beginning or at the end.

For another example, in the embodiment of the present application, the scene types corresponding to 5 consecutive segments corresponding to the segment after the beginning and/or the segment before the end of the music may be bbbbbbb, respectively, so that the generated video has the effect of expanding narration in the corresponding segment.

For another example, in the embodiment of the present application, the scene types corresponding to 5 consecutive segments corresponding to the refrain part of the music may be CCCCA, respectively, so that the narration of the video is improved to the climax effect at the refrain part of the generated video.

It should be noted that, the embodiments of the present application include, but are not limited to, specific implementations of scene types corresponding to multiple continuous segments of the above music.

Thus, the electronic apparatus can adjust the arrangement order of the materials in accordance with the scene type of the section set by the beat point of the music.

In summary, the electronic device arranges the materials in the order according to the set scene sequence in the video template, adds the scene sense and the shot sense of the materials according to the moving mirror, the speed and the transition set in the video template, and generates the video with the playing effect corresponding to the video template, so that the generated video has better expressive force and tension in the aspects of description of the movie scenario, expression of the character thought and emotion, processing of the character relationship, and the like, thereby enhancing the artistic appeal of the generated video.

For convenience of explanation, a specific implementation of the video template is described with reference to table 1 and table 2, taking a parent-child type video template and a travel type video template as examples. In tables 1 and 2, the scene types are exemplified by three types of short scenes, medium scenes, and long scenes as exemplarily shown in fig. 7, where for convenience of description, a represents a scene type corresponding to a short scene, B represents a scene type corresponding to a medium scene, and C represents a scene type corresponding to a long scene.

TABLE 2 video template for types of travel

The specific implementation manner of transition in table 2 can refer to the description manner of transition in table 1, and is not described herein again.

It should be noted that the video template includes, but is not limited to, parameters related to scene type, moving mirror, speed and transition.

In addition, the video template can also adjust the moving mode of the lens of the video in a self-adaptive manner based on the frame of the material, so as to achieve the optimal playing effect. For example, when a banner video is generated, the electronic device may use a mode of moving a lens from top to bottom to achieve a maximum regional display effect of a vertical material; when a vertical video is generated, the electronic equipment can realize the maximum regional display effect of the material of the banner by using a left-to-right moving mode of the lens. Therefore, the method is beneficial to displaying the materials to the maximum extent by the video, enriches the content of the video and ensures the movie feeling and the picture feeling brought by the video.

In the embodiment of the present application, each scene type in the video template corresponds to a segment, and the durations of the segments may be the same or different. The electronic device may first place the user-selected material based on the duration of each segment in the video template. Typically, video material may be placed in longer-duration segments in preference to picture material. The electronic equipment adjusts the arrangement sequence of the placed materials based on the scene type corresponding to each segment, so that the scene type of the materials is matched with the scene type of the segments, and the materials selected by the user are ensured to appear at least once in the generated video and the same materials cannot be placed in the adjacent segments.

It should be noted that the embodiments of the present application are not limited to the above implementation manner to adjust the arrangement order of the materials in the video.

In addition, when the number of the materials selected by the user is large and the time length of the video is set to be small, the time length of the section corresponding to the scene type can be set to be small, so that all the materials can appear in the video once. When the number of the materials selected by the user is small and the time length of the video is set to be large, the electronic equipment can select one or more segments from the video materials to repeatedly appear in the generated video for N times, wherein N is a positive integer greater than 1. If the longer video duration cannot be met, the electronic device may repeat all the arranged materials M times in the generated video, where M is a positive integer greater than 1.

The electronic device may set a minimum duration and a maximum duration for the duration of the music corresponding to the video template, so as to ensure that the user-selected material appears at least once in the generated video.

Based on the foregoing description, the play effect of the video 3039 in fig. 3S is associated with the video template. In general, the video templates are different, and the playing effect of the video 3039 is different. When the user selects the video material 3031, the picture material 3032, the picture material 3033, the video material 3034, the picture material 3035, the picture material 3036, the picture material 3037 and the video material 3038, the video 3039 may include: a video material 3031, a picture material 3032, a picture material 3033, a video material 3034, a picture material 3035, a picture material 3036, a picture material 3037, and a video material 3038.

In this embodiment, the electronic device may recognize that the scene type corresponding to the video material 3031 is BCBBB, the scene type corresponding to the picture material 3032 is B, the scene type corresponding to the picture material 3033 is B, the scene type corresponding to the video material 3034 is CCCC, the scene type corresponding to the picture material 3035 is B, the scene type corresponding to the picture material 3036 is a, the scene type corresponding to the picture material 3037 is a, and the scene type corresponding to the video material 3038 is BCCCC.

The electronic device recognizes that the generated video 3039 can adopt a parent-child type video template based on the video material 3031, the picture material 3032, the picture material 3033, the video material 3034, the picture material 3035, the picture material 3036, the picture material 3037 and the video material 3038.

In some embodiments, if the parent-child type video template shown in table 1 is used, the electronic device places the video material 3031, the picture material 3032, the picture material 3033, the video material 3034, the picture material 3035, the picture material 3036, the picture material 3037, and the video material 3038 at the position corresponding to the music respectively according to the scene type corresponding to each segment of the music given in table 1 based on the respective scene types of the video material 3031, the picture material 3032, the picture material 3033, the picture material 3035, the picture material 3036, the picture material 3037, and the video material 3038, so as to obtain the video 3039.

In other embodiments, the electronic device may enhance the playing effect of the generated video according to the scene type of the plurality of continuous segments corresponding to the set music in the video template, which is beneficial to improving the shot feeling and the movie feeling of the video.

It should be noted that, in addition to the above two manners, the electronic device may set the scene type in the video template according to an actual situation and an empirical value, and the setting manner of the scene type in the video template is not limited in this embodiment of the application.

In the following, with reference to fig. 8A to 8E, the playback effect of the video generated by the electronic device based on the material selected by the user is illustrated.

Referring to fig. 8A to 8E, fig. 8A to 8E are schematic diagrams illustrating a playing sequence of each material when the electronic device plays the generated video.

As shown in fig. 8A, when the user selects the picture material 11, the picture material 12, the picture material 13, the picture material 14, and the picture material 15, the electronic apparatus determines that: the scene type in the video template is CCCBA, and the durations of the scene type CCCBA are 4x, 2x, and 2x, respectively, where x is 0.48 seconds, and the scene type of the picture material 11 is B, the scene type of the picture material 12 is B, the scene type of the picture material 13 is C, the scene type of the picture material 14 is a, and the scene type of the picture material 15 is C.

Based on the scene type in the video template and the respective scene types of the picture material 11, the picture material 12, the picture material 13, the picture material 14, and the picture material 15, the electronic device can know that a scene type C with a duration of 2x is absent in all the materials, so that all the materials cannot be accurately matched with the scene type in the video template. Since all material needs to appear at least once, the electronic device may change the genre type CCCBA in the video template to CBCBA.

Thus, the electronic apparatus adjusts the arrangement order of the

picture materials

11, 12, 13, 14, and 15 based on the scene type CBCBA, generating a video as exemplarily shown in fig. 8A.

In fig. 8A, the playing order of the picture material 11, the picture material 12, the picture material 13, the picture material 14, and the picture material 15 in the generated video is:

between 0-4 x: a picture material 13;

between 4x and 6 x: a picture material 11;

between 6x and 8 x: a picture material 15;

between 8x and 9 x: a picture material 12;

between 9x and 11 x: the picture material 14.

Further, the scene types corresponding to the video exemplarily shown in fig. 8A are CBCBA, respectively.

As shown in fig. 8B, when the user selects the picture material 21, the picture material 22, the picture material 23, the picture material 24, and the picture material 25, the electronic apparatus determines that: the scene type in the video template is CCCBA, and the durations of the scene type CCCBA are 4x, 2x, and 2x, respectively, where x is 0.48 seconds, and the scene type of the picture material 21 is C, the scene type of the picture material 22 is B, the scene type of the picture material 23 is C, the scene type of the picture material 24 is a, and the scene type of the picture material 25 is C.

Based on the scene type in the video template and the respective scene types of the picture material 21, the picture material 22, the picture material 23, the picture material 24, and the picture material 25, the electronic device can know that all the materials can accurately match the scene type in the video template. Thus, the electronic apparatus adjusts the arrangement order of the

picture materials

21, 22, 23, 24, and 25 based on the category type of CCCBA, and generates a video as exemplarily shown in fig. 8B.

In fig. 8B, the playing order of the picture material 21, the picture material 22, the picture material 23, the picture material 24, and the picture material 25 in the generated video is:

between 0-4 x: a picture material 23;

between 4x and 6 x: a picture material 21;

between 6x and 8 x: a picture material 25;

between 8x and 9 x: picture material 22;

between 9x and 11 x: the picture material 24.

Further, the scene types corresponding to the video exemplarily shown in fig. 8B are CCCBAs, respectively.

As shown in fig. 8C, when the user selects the picture material 31, the video material 32, the picture material 32, and the picture material 33, the electronic apparatus determines that: the scene type in the video template is CCCBA, and the duration of the scene type CCCBA is 4x, 2x, and 2x, respectively, where x is 0.48 seconds, and the scene type of the picture material 31 is B, the scene type of the video material 31 is B, the duration of the video material 31 is equal to x, the scene type of the video material 32 is C, the duration of the video material 32 is greater than or equal to 4x, the scene type of the picture material 32 is a, and the scene type of the picture material 33 is C.

Based on the scene type in the video template and the respective scene types of the picture material 31, the video material 32, the picture material 32, and the picture material 33, the electronic device can know that a scene type C with a duration of 2x is absent in all the materials, so that all the materials cannot be accurately matched with the scene type in the video template. Since all material needs to appear at least once, the electronic device may change the genre type CCCBA in the video template to CBCBA.

Thus, the electronic apparatus adjusts the arrangement order of the picture material 31, the video material 32, the picture material 32, and the picture material 33 based on the scene type CBCBA, generating a video as exemplarily shown in fig. 8C.

In fig. 8C, the playing order of the picture material 31, the video material 32, the picture material 32, and the picture material 33 in the generated video is:

between 0-4 x: video material 32;

between 4x and 6 x: a picture material 31;

between 6x and 8 x: a picture material 33;

between 8x and 9 x: video material 32;

between 9x and 11 x: the picture material 32.

Further, the scene types corresponding to the video exemplarily shown in fig. 8C are cbcbcbas, respectively.

As shown in fig. 8D, when the user selects the picture material 41, the video material 42, the picture material 42, and the picture material 43, the electronic apparatus determines that: the scene type in the video template is CCCBA, and the duration of the scene type CCCBA is 4x, 2x, and 2x, respectively, where x is 0.48 seconds, and the scene type of the picture material 41 is C, the scene type of the video material 41 is B, the duration of the video material 41 is equal to x, the scene type of the video material 42 is C, the duration of the video material 42 is greater than or equal to 4x, the scene type of the picture material 42 is a, and the scene type of the picture material 43 is C.

Based on the scene type in the video template and the respective scene types of the picture material 41, the video material 42, the picture material 42, and the picture material 43, the electronic device can know that all the materials can be accurately matched with the scene type in the video template. Thus, the electronic apparatus adjusts the arrangement order of the picture material 41, the video material 42, the picture material 42, and the picture material 43 based on the category type of CCCBA, to generate a video as exemplarily shown in fig. 8D.

In fig. 8D, the playing order of the picture material 41, the video material 42, the picture material 42, and the picture material 43 in the generated video is:

between 0-4 x: a video material 42;

between 4x and 6 x: a picture material 41;

between 6x and 8 x: a picture material 43;
