In some embodiments, the terminal may determine the at least one key video frame from the video clip by: determining the score of a video frame corresponding to each playing time point in the video based on the video information corresponding to each playing time point; determining at least one key video frame from the video clip based on the score of the video frame corresponding to each playing time point; wherein the score is used for representing the possibility that the video frame corresponding to the playing time point is a key video frame.

In some embodiments, the terminal may determine the score of the video frame corresponding to the corresponding playing time point in the video by: determining a first score of a video frame corresponding to each playing time point in the video based on the historical playing speed corresponding to each playing time point; determining a second score of a video frame corresponding to each playing time point in the video based on the historical interactive data corresponding to each playing time point; determining a third score of a video frame corresponding to each playing time point in the video based on the background music corresponding to each playing time point; respectively obtaining weights corresponding to the first score, the second score and the third score; and determining the score of the video frame corresponding to the corresponding playing time point in the video based on the first score, the second score, the third score and the corresponding weight.

In practical application, the terminal may determine the first score of the video frame corresponding to the playing time point in the video in the following manner. Here, the terminal acquires a history play speed, such as 2 × speed, 0.5 × speed, or the like, at which the user plays the video. And determining a target historical playing speed corresponding to the longest playing time when the user plays the whole video for each user, and analyzing by taking the target historical playing speed as a reference. Specifically, since the highlight level of the video content can be determined according to whether the user turns on the double speed, in the embodiment of the present invention, the corresponding relationship between the playing speed and the highlight level is preset, and the corresponding relationship includes 6 levels, as shown in table 1:

playing speed	0.5	1	1.25	1.5	2	Skip over
							Wonderful grade	5	4	3	2	1	0

TABLE 1 corresponding relationship between Play speed and highlight level

In practical applications, the score of the video frame corresponding to the reference playing speed may be set to 1, and the score of the skipped video frame may be set to 0, where the score is used to represent the possibility that the video frame corresponding to the playing time point is the key video frame. Score S of video frame corresponding to other playing speed_nThe calculation can be made by the following formula:

S_n＝1+(Ln-L)*0.2

wherein, Ln is the level corresponding to the playing speed, and L is the reference level. For example, in a 40-minute video, if a user views 30 minutes of content at 1.5 × speed, views 5 minutes of content at 1 × speed, and skips five minutes of content, the score of 1.5 × speed video frames is 1, the score of 1 × speed video frames is 1+ (4-2) × 0.2 ═ 1.4, and the score of skipped video frames is 0.

Based on this, the score of the video frame of each playing time point can be obtained for each user, and finally the scores of the video frames of each playing time point corresponding to all the users are added and averaged to obtain the first score of the video frame of each playing time point of the video.

In practical application, the terminal may determine the second fraction of the video frame corresponding to the playing time point in the video as follows. Here, the terminal identifies whether the video has background music to obtain an identification result; and determining a second score of the video frame of each playing time point of the video based on the recognition result. Specifically, the score of the video frame in which the background music exists may be set to 1, and the score of the video frame in which the background music does not exist may be set to 0, so as to obtain the second score of the video frame at each play time point of the video.

In practical applications, the terminal may determine the third fraction of the video frames corresponding to the playing time point in the video as follows. Here, the terminal acquires interaction information, such as a pop-up screen, a pop-up comment, and the like, performed by the user on the video frame at each playing time point during the playing of the video, so as to determine a third score of the video frame at each playing time point of the video based on the interaction information at each playing time point. Specifically, the third score may be determined according to the number of pop-ups corresponding to the video frame at each playing time point and the like amount for each pop-up, for example, the score of one pop-up is set to 1, and the score of one like is set to 0.5. Meanwhile, in order to avoid that the score obtained based on the calculation is too high and influences other scores, the score obtained by the calculation is subjected to normalization processing, so that a third score of the video frame of each playing time point of the video is obtained.

After the first score, the second score and the third score of the video frame of each playing time point of the video are obtained, the weights corresponding to the first score, the second score and the third score are respectively obtained, so that the score of the video frame of each playing time point of the video is obtained based on the first score, the second score, the third score and the corresponding weight.

And finally, selecting at least one key video frame from the video clips obtained based on the key character recognition based on the obtained scores of the video frames of each playing time point in the video, so as to generate a key content display diagram of the key content of the video based on the selected at least one key video frame.

By applying the embodiment of the invention, the generation function item of the key content display diagram corresponding to the video is presented on the playing interface of the video, and the key content display diagram for representing the key content of the video is generated when the trigger operation aiming at the generation function item is received.

Referring to fig. 9, fig. 9 is a schematic flowchart of an information processing method for a video according to an embodiment of the present invention, where the information processing method for a video according to an embodiment of the present invention includes:

step 901: and the first terminal runs the first client and presents the generation function item of the key content display chart corresponding to the video in the playing interface of the video.

Here, the first terminal is provided with a first client for video playback. When a user watches a video through a client arranged on a terminal, if a key content display graph of the video needs to be generated, a generation function item displayed in a playing interface of the video can be clicked to trigger a generation instruction of the key content display graph corresponding to the video.

Step 902: and responding to the trigger operation aiming at the generating function item, and sending a generating instruction of the key content display graph of the corresponding video to the server.

Step 903: and the server receives and responds to the generation instruction, acquires video information corresponding to the video and identifies video clips corresponding to key people in the video.

Here, the video information includes at least one of a historical play speed, historical interaction data, and background music. The server can determine the score of the video frame corresponding to the corresponding playing time point in the video based on the video information corresponding to each playing time point, and the score is used for representing the possibility that the video frame corresponding to the playing time point is the key video frame.

Step 904: and determining at least one key video frame from the video clip based on the acquired video information corresponding to each playing time point.

Here, specifically, the server determines at least one key video frame from the video clips based on the score of the video frame corresponding to each playing time point.

Step 905: at least one key video frame of a video is obtained, and text content associated with each key video frame is obtained.

Step 906: the text content is combined with the corresponding key video frames to generate a key content presentation graph based on the combination result.

After determining at least one key video frame of the video, the server acquires the key video frame and text content associated with each key video frame, such as subtitle information, historical background information, key character information, plot information and the like.

And combining the key video frames and the text content associated with each key video frame to obtain a key content display diagram. Specifically, a presentation graph generation template corresponding to the video may be acquired, the text content and the corresponding key video frame may be combined based on the acquired presentation graph generation template, so as to generate a key content presentation graph based on the combination result.

Step 907: and sending the key content display graph of the video to the first terminal.

Step 908: the first terminal receives the key content exhibition 10 diagram returned by the server and shares the key content exhibition diagram to the second terminal.

Here, the playing interface also presents a sharing function item corresponding to the key content display diagram, and the user can share the key content display diagram to other people through the sharing function item. After receiving the sharing instruction triggered based on the sharing function item, the first terminal shares the generated key content display graph to other users (namely, sends the key content display graph to the second terminal) so as to realize the transmission and sharing of the video.

Step 909: the second terminal receives the key content display graph and receives scanning operation aiming at the graphic code in the key content display graph.

Here, the key content display diagram further includes a graphic code corresponding to the video, and the user can scan and identify the graphic code through operation, so that the video can be viewed.

Step 910: and responding to the scanning operation aiming at the graphic code, jumping to the playing interface of the video from the current page, and playing the video based on the playing interface of the video.

By applying the embodiment, the key content display graph used for representing the key content of the video can be quickly generated by setting the generating function item of the key content display graph of the video, so that a user can be helped to better know the content of the video; and the key content is also provided with a graphic code corresponding to the video, so that a user can conveniently and quickly enter a video watching interface, and the video transmission is facilitated.

An exemplary application of the embodiments of the present invention in a practical application scenario will be described below.

Currently, if a user wants to browse a video quickly, only a trailer or a text introduction can be used, and the manual intervention is needed, and the cost is high. At present, no scheme for automatically generating a video introduction long graph exists, and although the splicing technology of the long graph is quite simple, the most critical part for generating the introduction long graph is the interpretation of video contents. In the related art, the heat of the video is represented by a curve, as shown in fig. 10, the curve is generated by judging the heat according to whether the user skips the segment, although the user can be referred to for a certain degree, as can be seen from fig. 10, the curve is very gentle, and it is very difficult for the user to understand the key content of the video. In addition, the wonderful shots of the sports game videos can be analyzed through traditional shot segmentation, machine learning and other methods, but the scheme is only suitable for the situation that the video scene is single and the shot segmentation detection is easy to perform, and most videos (such as movies, TV shows, synthesis art and the like) use various artistic techniques to process the shots, so that the content is difficult to analyze through similar methods to obtain the key content of the videos.

Based on this, embodiments of the present invention provide a video information processing method to solve at least the above existing problems, and the following detailed description is provided. Referring to fig. 11, fig. 11 is a schematic flowchart of an information processing method for a video according to an embodiment of the present invention, where the information processing method for a video according to an embodiment of the present invention includes:

step 1101: and the terminal runs the client.

Here, the terminal is provided with a client for video playback.

Step 1102: and displaying the generation function item of the key content display diagram of the corresponding video in the playing interface of the video.

Step 1103: and responding to the trigger operation aiming at the generating function item, and sending a generating instruction of the key content display graph of the corresponding video to the server.

Here, when a user watches a video through a client installed in a terminal, if a key content display diagram of the video needs to be generated, a generation instruction corresponding to the key content display diagram of the video may be triggered by clicking a generation function item presented in a playing interface of the video, which may be referred to in fig. 3.

Step 1104: the server receives and responds to the generation instruction to acquire video information of the video.

Step 1105: and determining whether the video has the label of the artificial node, if so, executing step 1109, and if not, executing step 1106.

Referring to fig. 12, fig. 12 is a schematic view of a video labeled with artificial nodes according to an embodiment of the present invention, where video content is labeled in a node manner on a display progress bar of the video, and each node corresponds to a key video frame of the video. When a trigger operation of a user for a certain node is received, annotation content corresponding to the node video, such as 'XXX to XX song', can be presented. In practical application, if the video is labeled with artificial nodes, the video frames corresponding to the nodes and the labeled text content can be directly used to generate a key content display diagram in a combined manner.

Step 1106: and determining whether a trailer corresponding to the video exists, if so, executing step 1107, and if not, executing step 1108.

Because the content of the video is many, in order to reduce the calculation time, in practical application, whether the video has a corresponding trailer can be judged, if yes, the trailer of the video can be directly analyzed to obtain a key video frame so as to generate a key content display diagram; and if the key video frames do not exist, analyzing the content of the video to obtain key video frames so as to generate a key content display graph.

Step 1107: and analyzing the content of the trailer corresponding to the video.

Step 1108: and performing content analysis on the video.

Here, the server may perform content analysis based on a playback speed, interactive information, background music, key character recognition, and the like, and the following description will be given in detail taking the example in which the server performs content analysis on a video.

First, the server performs content analysis on the video based on the play speed. Here, the server acquires a history playing speed of the user playing the video, such as 2-time speed, 0.5-time speed, and the like. And determining a target historical playing speed corresponding to the longest playing time when the user plays the whole video for each user, and analyzing by taking the target historical playing speed as a reference. Specifically, since the highlight level of the video content can be determined according to whether the user turns on the double speed, in the embodiment of the present invention, the corresponding relationship between the playing speed and the highlight level is preset, and the corresponding relationship includes 6 levels, as shown in table 1:

playing speed	0.5	1	1.25	1.5	2	Skip over
							Wonderful grade	5	4	3	2	1	0

TABLE 1 corresponding relationship between Play speed and highlight level

In practical applications, the score of the video frame corresponding to the reference playing speed may be set to 1, and the score of the skipped video frame may be set to 0, where the score is used to represent the possibility that the video frame corresponding to the playing time point is the key video frame. The scores of the video frames corresponding to other playing speeds can be calculated by the following formula:

S_n＝1+(Ln-L)*0.2

Second, the server performs content analysis on the video based on the background music. Here, the server identifies whether the video has background music to obtain an identification result; and determining a second score of the video frame of each playing time point of the video based on the recognition result. Specifically, the score of the video frame in which the background music exists may be set to 1, and the score of the video frame in which the background music does not exist may be set to 0, so as to obtain the second score of the video frame at each play time point of the video.

Thirdly, the server analyzes the content of the video based on the interactive information. Here, the server obtains interaction information, such as a pop-up screen, a pop-up comment, and the like, performed by the user on the video frame at each playing time point during the playing of the video, so as to determine a third score of the video frame at each playing time point of the video based on the interaction information at each playing time point. Specifically, the third score may be determined according to the number of pop-ups corresponding to the video frame at each playing time point and the like amount for each pop-up, for example, the score of one pop-up is set to 1, and the score of one like is set to 0.5. Meanwhile, in order to avoid that the score obtained based on the calculation is too high and influences other scores, the score obtained by the calculation is subjected to normalization processing, so that a third score of the video frame of each playing time point of the video is obtained.

Fourth, the server performs content analysis on the video based on key character recognition. Here, the server performs key person identification for each video frame of the video, and divides the video based on the identified key persons to obtain a video clip including each key person. For example, for a 20 minute segment, 0-5 minutes for a female hero segment, 5-8 minutes for a male hero segment, and 10-14 minutes for a male and female major-on-screen segment, we divide the movie into five video segments, 0-5, 5-8, 8-10, 10-14, and 14-20.

Step 1109: and determining a key video frame corresponding to the video based on the analysis result.

Here, based on the analysis result, the score of the video frame of each playing time point of the video is obtained. Specifically, the weights of the first score, the second score and the third score are analyzed according to manual investigation and actual conditions, and the score of the video frame of each playing time point of the video is obtained based on the corresponding weights.

Then, at least one key video frame is selected from the video clips based on the scores of the video frames of each playing time point. In practical applications, for each video segment divided based on key character recognition, given a minimum threshold value N and fluctuation range a, the highest score of video frames S1 is selected, corresponding to time point t1, the video segment is discarded if S1 is less than N, and a time period [ ta, tb ] is selected if S1 is greater than N, such that t1 is included between ta and tb, and the score of each video frame between ta and tb is guaranteed to be greater than N-a. Similarly, we choose the second time period with this rule. And after two time periods are obtained, taking the video frame corresponding to the highest score or a plurality of video frames which are sequenced according to the scores and are positioned at the front as the key video frame of the video.

Step 1110: based on the selected key video frames, a key content presentation graph of the video is generated.

Here, after obtaining the key video frames, text content associated with each key video frame, such as subtitle information, may be obtained, so that a key content display long image of the video is generated by combining and splicing the key video frames and the text content associated with the key video frames.

Specifically, the server may store a table of playing time points for the videos, and after determining the key video frames, the key video frames and the associated text content may be spliced according to the playing time point of each key video frame.

Meanwhile, when the key content display long graph is generated, the graph code corresponding to the video can be generated, so that when the electronic equipment triggers the scanning operation aiming at the graph code, the page can be directly jumped to the playing interface of the video, and the video can be conveniently spread.

Step 1111: and sending the key content display graph of the video to the terminal.

Step 1112: and the terminal receives and presents the key content display graph returned by the server.

Here, the terminal receives the key content presentation graph returned by the server, and may perform operations such as storing and sharing on the key content presentation graph.

In addition, the key content display diagram also comprises a graphic code of the video, and a user can enter a playing interface of the video by scanning the graphic code to watch the video.

By applying the embodiment, the feedback information of the existing user for the video can be fully utilized to generate the key content display long picture for introducing the video, so that the user can better know the content of the video, and the propagation of the original video is facilitated.
