Fig. 2 shows a method for generating video information according to an embodiment of the present application, applied to a user equipment, and the method includes steps S101 and S102.
Specifically, in step S101, the user equipment obtains one or more recorded first video information, where each first video information corresponds to a preset sorting order. Each of the first video information includes portrait information, the portrait information in each of the first video information may be a same person (e.g., person a) or a person recorded by a different person (e.g., person A, B, C …), and each of the first video information includes at least one picture of the portrait information from a start playing point to an end playing point. In some embodiments, there is at least one first video information in the one or more first video information, where portrait information in each first video information in the at least one first video information is multiple (for example, two or more portraits appear in a video of the first video information a), the one or more video information is recorded by the user equipment, and the user equipment sorts each first video information after completing recording the one or more first video information, where in some embodiments, the preset sorting order includes at least any one of:
1) the recording completion time sequence of each first video information;
2) the user manually adjusts the sequence of each first video information;
for example, the user equipment receives a video production task, where the video recording task includes recording one or more first video information, for example, the user equipment is recording first video information 1, the user equipment starts recording first video information 2 after the recording of first video information 1 is completed, the user equipment starts recording first video information 3 after the recording of first video information 2 is completed, and the user equipment starts recording first video information 4 after the recording of first video information 3 is completed. That is, the one or more recorded first video information are first video information 1, first video information 2, first video information 3, and first video information 4, respectively, and the user equipment allocates a corresponding sorting order to each first video information according to the recording completion time of each first video information, as in the foregoing example, the sorting order of each first video information is represented according to a sorting number, and the sorting order is in direct proportion to the superposition relationship between each first video information, that is, the position of the subsequent first video information displayed in the picture is higher the sorting order is, for example, the sorting order of the first video information 1 is the highest, and the portrait video information extracted from the first video information 1 is not blocked by other video information. In some embodiments, each first video information is recorded with a predetermined time countdown (e.g., 5s), which may facilitate the preparation of the person to be photographed, and may also allow the user time to adjust the photographing content according to the related content extracted from the first video information 1 (e.g., the subsequent portrait video information) when the first video information 2, the first video information 3, and the like are subsequently photographed. In some embodiments, the video duration of each first video information is consistent, so that the target video can be synthesized with the second video information according to the related content of each video information.
For another example, after the user equipment sequences a plurality of pieces of first video information according to the video recording completion time (e.g., first video information 1, first video information 2, first video information 3, and first video information 4), the user manually adjusts the sequence of the plurality of pieces of first video information, and in some embodiments, each time one piece of first video information is recorded, the user equipment performs a capture operation on a video frame of the first video information (e.g., captures a video frame at the start play point of the first video information, or a video frame at any time point), where the captured video frame is used to identify the first video information corresponding to the video frame, and is applied to the video sequencing aspect, for example, a video frame captured by first video information 1, a video frame captured by first video information 2, a video frame captured by first video information 3, The video frames of the screenshots of the first video information 4 are arranged in sequence, and the user can adjust the sequence of the plurality of first video information by moving the sequence of the screenshots of the first video information 4, for example, the video frame of the screenshots of the first video information 3 is adjusted to be before the video frame of the screenshots of the first video information 1, and based on the adjustment operation, the sequence of the first video information acquired by the user equipment from front to back is as follows: first video information 3, first video information 2, first video information 1, first video information 4.
In some embodiments, the method further comprises step S104 (not shown), and in step S104, the user equipment generates one or more recorded first video information. For example, the generating process of the one or more first video information is a recording process of the one or more first video information. After the one or more first video information are recorded completely, the user equipment acquires the one or more first video information to provide a basis for subsequently completing a production task of the target video.
In some embodiments, the generating one or more recorded first video information comprises: recording first video information; extracting portrait video information in the first video information from the first video information, and recording the portrait video information in the first video information as recording reference information to obtain second first video information; extracting portrait video information in the second first video information from the second first video information, and recording third first video information by taking the portrait video information in the first video information and the portrait video information in the second first video information as recording reference information; by analogy, recording the (N + 1) th first video information by taking the portrait video information in the first video information to the portrait video information in the Nth first video information as recording reference information, wherein N is a positive integer; and generating one or more recorded first video information according to the first video information to the (N + 1) th first video information. For example, the user equipment records first video information, where the first video information includes portrait information and background information, a video duration of the first video information is a preset duration (e.g., 5min), and then, in response to a recording operation of a user, the user equipment prepares to capture second first video information, and in some embodiments, the extracting portrait video information from the first video information, and recording the portrait video information from the first video information as recording reference information to record the second first video information includes: performing portrait segmentation on the first video information to extract portrait video information in the first video information, and storing background video information except the portrait video information; and when the second first video information is recorded, displaying the portrait information in the portrait video information in a recording picture of the second first video information to be used as recording reference information to record the second first video information. For example, the user equipment separates portrait video information in the first video information from the first video information (i.e. removes background video information in the first video information, and only obtains portrait video information), for example, the operation of separating portrait video information includes: the user equipment converts the first video information into an image of one frame, then separates the images of each frame, for example, the user equipment may use an image segmentation api (e.g., Face + +, remove. bg, aip) or a neural training network to separate the images, and combines the processed images of each frame to generate the image video information. At this point, the portrait video information is free of any background information (transparent, if any). In some embodiments, the user equipment separates the portrait video information from the background video information in the first video information without deleting the background video information, and the user equipment retains the background video information so that the background video information of the first video information is used as the background video information of the generated target video when the ordering of the first video information is adjusted to the end.
When the second first video information starts to be recorded (for example, when the progress is 0: 00), the user equipment presents the portrait video information in a picture-in-picture mode in a recording picture of the second first video information. In some embodiments, when the second first video information starts to be recorded, the user equipment presents a preset video frame of the portrait video information (for example, a starting portrait frame of the portrait video information, a portrait frame corresponding to a time point preset by the user equipment) in the recorded frame of the second first video information, so as to serve as recording reference information when the user records the second first video information, that is, a specific position of a person in a previous video on a screen can be seen in real time when the second first video information is recorded. In some embodiments, when the second first video information starts to be recorded, the user equipment presents a starting video picture of the portrait video information in a recorded picture of the second first video information, and when a progress bar of the second first video information starts to change, the recorded picture presented in the second first video information also changes into a portrait picture corresponding to the progress in the portrait video information (for example, when the progress bar of the second first video information is 0:02, the portrait video information itself plays at a progress of 0: 02), so as to serve as recording reference information when the user records the second first video information, that is, when the second first video information is recorded, the user can see a specific position of a character in a previous video on a screen in real time. It is convenient to think about the recording of the character in the second first video information according to the previous character picture (e.g., the current action, expression, language, etc. of the character) (e.g., the action, expression, language, etc. of the character), after the second first video information is generated according to the above-mentioned thought, the user equipment prepares to shoot the third first video information in response to the user's recording operation, the user equipment separates the portrait video information in the second first video information from the second first video information, in some embodiments, the separation of the portrait video information in the second first video information is identical to the separation of the portrait video information in the first video information, and no repeated statement is made here, and the user equipment has obtained the portrait video information in the first video information, when the third first video information starts to be recorded, the user equipment uses the portrait video information in the second first video information and the portrait video information in the first video information as recording reference information for recording the third first video information, for example, the user equipment may present a portrait picture at a time point preset in the portrait video information of the second first video information and a portrait picture at a time point preset in the portrait video information of the first video information in a recording picture of the third first video information, wherein the portrait picture at a time point preset in the portrait video information of the first video information is presented in a sequence before the portrait picture at a time point preset in the portrait video information of the second first video information, and in some embodiments, the portrait picture in the portrait video information of the first video information in the recording picture of the third first video information, The portrait frame in the portrait video information of the second first video information, which is present in the third first video information recording frame, changes with the change of the recording progress bar (for example, when the recording progress is 0:05s, the portrait video information of the two first video information is played to the progress of 0:05 s), and so on, when the N +1 th first video information needs to be recorded, the portrait information corresponding to all the first video information before the N +1 th first video information is present in the recording frame of the N +1 th first video information, so as to be used as the recording reference information for the recording at this time. Here, the first video information and the second video information … N +1 th video information generated in the foregoing are used as one or more recorded first video information to be acquired by the user equipment.
In some embodiments, the presenting the portrait information in the portrait video information in the recording picture of the second first video information to record the second first video information as the recording reference information includes: determining first position information of portrait information in the portrait video information in the first video information; determining second position information of the portrait information in the portrait video information presented in the recording picture of the second first video information according to the first position information; and recording the portrait information in the portrait video information presented in the second position information as recording reference information to the second first video information. For example, in order to make the portrait information as the recording reference information more accurate, the user equipment needs to correspond the position of the portrait information in the portrait video information in the first video information with the position of the portrait information as the recording reference information in the second first video information. In some embodiments, the user device uses a static portrait information in the portrait video information as the recording reference information, and the user device uses a starting portrait frame of the portrait video information or a portrait frame corresponding to a predetermined time point as the portrait information, and the portrait information is statically fixed in a position for reference when the user records, for example, the portrait information is a portrait frame at a schedule of 0:10, and at the schedule, the portrait frame is located in a first position information (for example, a vertical line screen edge A1cm away from the left and a horizontal line screen edge A2cm away from the top) in a video frame of a first video information, and then, when the portrait information is used as the recording reference information, at the start of recording a second first video information, the user device determines a second position information (namely, a screen edge A1cm away from the left, a screen edge a cm away from the left, a horizontal line screen edge a cm away from the top) of the video frame of the second first video information, The upper horizontal line screen edge A2cm) and performs recording based on the recording reference information.
In some embodiments, the user equipment uses the entire dynamic portrait information in the portrait video information as the recording reference information, and the user equipment uses the entire moving picture performed by the portrait in the portrait video information as the portrait information, and the portrait information dynamically moves at different positions for the user to record as a reference, for example, from a starting playing point to an ending playing point, the portrait in the first video information runs from a left vertical line screen edge until a right vertical line screen edge, so that the motion track of the portrait changes corresponding to different progress time points. Then, when the portrait information is used as recording reference information and the second first video information starts to be recorded, the user equipment determines first position information of the portrait information at each time point in the first video information, and maps the first position information at each time point to a video picture corresponding to a recording time point of the second first video information to determine second position information of the portrait information in the video picture corresponding to each recording time point of the second first video information, that is, when the user shoots the second first video information, the recording scheme can be adjusted according to the position of the portrait information at each recording time point in the picture, so that the second first video information can generate a better synthetic effect when being subsequently recorded and participating in synthesizing a target video.
In step S102, the user equipment generates target video information according to the portrait video information corresponding to each of the one or more pieces of recorded first video information and the recorded second video information, where a video duration of each of the one or more pieces of recorded first video information is consistent with a video duration of the second video information. For example, the portrait frame in each recorded first video information keeps being presented from the video starting stage to the video ending stage, the portrait frame in each first video information includes one or more portraits, where only one portrait frame in each first video information is exemplified, where, on the premise that the portrait frame in each recorded first video information keeps being presented from the video starting stage to the video ending stage, the video duration of each portrait video information separated from each first video information is consistent with the duration of the first video information, in some embodiments, there is a case where the video duration of the separated portrait video information is inconsistent with the duration of the first video information (i.e., there is a case where the video duration of the portrait video information is inconsistent with the duration of the second video information), in which case, less than the number of people in the video frame corresponding to one time point may exist in the finally synthesized target video information, the video frame is a video frame at the starting time point The number of people in the face. In some embodiments, the video duration of the portrait video information corresponding to each piece of first video information is consistent with the video duration of the second video information, and the blocking sequence of the portrait video information corresponding to each piece of first video information in the target video information is consistent with the preset sorting sequence corresponding to each piece of first video information. The occlusion order is a superposition relationship of the portrait video information corresponding to each piece of the first video information, for example, the order of the plurality of pieces of first video information is: the first video information 1 and the first video information 2 are, in the subsequently generated target video information, a picture corresponding to the portrait video information in the first video information 1 is in front of a picture corresponding to the portrait video information in the first video information 2 (that is, there is a high probability that the picture corresponding to the portrait video information in the first video information 1 blocks the picture corresponding to the portrait video information in the first video information 2).
In some embodiments, the second video information is ordered after the one or more recorded first video information. For example, the recording completion time of the one or more recorded first video information is earlier than the recording completion time of the second video information, and the user does not adjust the sorting order of the second video information. And on the premise that the sequencing order of the second video information is behind the one or more recorded first video information, the second video information does not need to be subjected to portrait separation when the target video information is subsequently generated. Here, the one or more first video information and the second video information are generated after the user records through the user equipment, and only the difference is that the one or more first video information needs to be separated from corresponding portrait video information to be combined with the second video information to generate the target video information, wherein the second video information does not need to be separated from the portrait, and the background video information of the second video information is used as the background information of the subsequent target video information.
In some embodiments, the method further includes step S103 (not shown), in step S103, the user equipment plays the target video information from a play start point of the target video information, where the corresponding one or more portrait information in each first video information in the video picture corresponding to the play start point and the portrait information in the second video information are forward overlaid in the order of sorting. For example, after the target video information is generated, the user equipment plays the target video information, and at the play starting point of the target video information, the portrait video information corresponding to each piece of first video information is presented in the target video information in a manner of overlaying the video pictures presented in the second video information, where the overlaying presentation is determined by the ordering order of each piece of first video information (i.e., the ordering order of the portrait video information corresponding to each piece of first video information), for example, the ordering order is from first to last: the video information processing method comprises first video information 1, first video information 2, first video information 3, first video information 4 and second video information 1, namely, a presented video picture is that portrait video information of the first video information 1 blocks portrait video information of the first video information 2, portrait video information of the first video information 2 blocks portrait video information of the first video information 3, and portrait video information of the first video information 3 blocks portrait video information of the first video information 4 and is superposed in the second video information 1. In the process of playing the target video information, the portrait video information extracted from the first video information 1, the portrait video information extracted from the first video information 2, the portrait video information extracted from the first video information 3, and the portrait video information extracted from the first video information 4 are played simultaneously along with the movement of the progress bar of the second video information 1, if the portraits in the plurality of videos are the same recorded figure, the effect that different individuals of the same person move in the same video picture can be presented in the playing process of the target video, so that the video generation of one-figure multi-role is more efficient, in some embodiments, if the portraits in the plurality of videos are different figures, the effect that different people move in the same video picture can be presented in the playing process of the target video, thereby improving the efficiency of the user in clipping the video.
In some embodiments, the method further includes step S105 (not shown), and in step S105, the user equipment acquires the recorded second video information. For example, the second video information may be uploaded after the user completes recording, or may be recorded by the user with reference to the portrait content of the one or more first video information. If the second video information is recorded by the user referring to the portrait content of the one or more first video information, then the generated video engagement degree is higher when the target video information is subsequently generated according to the portrait video information corresponding to each first video information and the second video information.
In some embodiments, the obtaining the recorded second video information includes: acquiring portrait information in portrait video information in each piece of first video information; when the second video information is recorded, displaying the portrait information in the portrait video information in each piece of first video information in a recording picture of the second video information to be used as recording reference information to record the second video information; and acquiring the recorded second video information after the second video information is recorded. For example, the recording mode of the second video information may refer to the aforementioned recording mode of recording the (N + 1) th first video information, that is, the portrait information in the portrait video information in each first video information is presented in the recording picture of the second video information for a recording reference, in some embodiments, the user equipment determines the position information of the portrait information in each portrait video information in the corresponding first video information, so as to determine the position information of the portrait information in each portrait video information in the video picture of the second video information based on the position information, so that the recording of the second video information has a reference basis, and the subsequently generated target video information meets the requirements of the user.

For example, the one or more first video information and the second video information are ordered in sequence (e.g., the first video information 1, the first video information 2, the first video information 3, the first video information 4, and the second video information 1), and in response to a user's trigger operation on at least one of the video information, for example, the user re-records the first video information 2 and the first video information 3, the ordering sequence of the two first video information in all the video information is not changed, and only the video content is changed. The multiple candidate video information generated at this time include first video information 1, re-recorded first video information 2, re-recorded first video information 3, first video information 4, and second video information 1, and the user equipment then generates target video information according to portrait video information extracted from the first video information 1, the re-recorded first video information 2, the re-recorded first video information 3, and the first video information 4, and the second video information 1.
In some embodiments, the preset operation includes an operation of adjusting a sorting order of the at least one video information, and the generating the target video information according to the corresponding portrait video information and the last candidate video information in each of the first M candidate video information of the plurality of candidate video information includes: and generating target video information according to the portrait video information corresponding to each candidate video information in the first M candidate video information in the plurality of candidate video information, the third position information of the portrait video information corresponding to each candidate video information in the candidate video information, the adjusted ordering sequence of each candidate video information and the last candidate video information. For example, the one or more first video information and the second video information are ordered in sequence (for example, in response to a sequence adjustment operation of the user (for example, before the first video information 3 is adjusted to the first video information 2 and before the second video information 1 is adjusted to the first video information 1), the generated plurality of candidate video information includes the second video information 1, the first video information 3, the first video information 2 and the first video information 4, the user equipment respectively extracts portrait video information corresponding to the second video information 1, the first video information 3 and the first video information 2, since the background video information of the video is reserved when the user equipment performs the face separation on the video, the first video information 4 is a complete video and is not segmented. And then the user equipment generates target video information according to the second video information 1, the first video information 3, the portrait video information corresponding to the first video information 2 and the first video information 4. In some embodiments, the generating the target video information according to the corresponding portrait video information in each candidate video information of the first M candidate video information of the plurality of candidate video information, the third position information of the corresponding portrait video information in each candidate video information in the candidate video information, the adjusted sorting order of each candidate video information, and the last candidate video information includes: extracting corresponding portrait video information in each candidate video information in the first M candidate video information; determining fourth position information of each portrait video information in the picture of the last candidate video information according to the third position information of the corresponding portrait video information in each candidate video information in the candidate video information; and presenting each portrait video information in the picture of the last candidate video information according to the fourth position information, and performing superposition sorting on the portrait video information according to the sorting sequence adjusted by each candidate video information to generate target video information, wherein the sequence of the portrait video information in the last candidate video information is positioned behind each portrait video information. For example, on the premise that the user equipment separates the portrait video information from each candidate video information in the first M candidate video information, the user equipment determines third location information (for example, a dynamic location moving in real time, or location information of a picture in the portrait video information corresponding to a certain progress time point in the candidate video information) of each portrait video information in the corresponding candidate video information, and then, the user equipment determines fourth location information of each portrait video information in the picture of the last candidate video information according to the third location information, and the specific manner of determining the fourth location information may refer to the foregoing: and determining second position information of the portrait information in the portrait video information presented in the recording picture of the second first video information according to the first position information.
