Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Fig. 1 is a flowchart illustrating a special effect video recording method according to a first embodiment of the present invention. It should be noted that the method of the present invention is not limited to the flow sequence shown in fig. 1 if the results are substantially the same. As shown in fig. 1, the method comprises the steps of:
step S101: when the video recording starts, the obtained video data is divided into two paths, and one path of video data is stored as initial video data.
Specifically, when a user records a short video through the mobile terminal, a camera of the mobile terminal shoots a target object, so that shot video data is acquired. The image in the acquisition range of the camera generates an optical image through the camera, the generated optical image is projected onto the surface of the image sensor, then the optical image is converted into an electric signal, and the electric signal is converted into a digital image signal after A/D (analog to digital conversion), namely the video data in the embodiment is formed. After video data are obtained, the video data are divided into two paths to be processed respectively, the two paths do not interfere with each other, and one path of video data is stored as initial video data and is used for subsequent video coding storage; and the other path of video data is used for previewing after special effect processing is carried out, so that the user can conveniently set the required effect. Wherein, the mobile terminal can also be provided with a buffer pool for storing initial video data.
It should be noted that, in the process of recording a video, the video recording function on the mobile terminal may be turned on to start recording the video, and the video recording function may be turned on in various ways. Firstly, a video recording function is started when a user manually triggers a function touch key displayed on a touch screen of the mobile terminal; secondly, the user can start the video recording function through voice control; and thirdly, automatically starting a video recording function after detecting that a preset target object appears in a picture shot by a camera of the mobile terminal, wherein the target object can be a person or an object, a human face or a gesture action of the person and the like. The embodiment does not limit the manner in which the video recording function starts.
Step S102: and carrying out special effect processing on the other path of video data according to the special effect selected by the user, generating and displaying a preview video, and obtaining the target special effect finally selected by the user.
Specifically, after the special effect selected by the user and the other path of video data are obtained, the other path of video data is subjected to real-time special effect processing according to the special effect, and the preview video with the special effect added is obtained. And displaying the preview video to a user, if the user is satisfied with the effect of the preview video, confirming that the special effect is selected as a target special effect by the client, if the user is not satisfied with the effect of the preview video, replacing the special effect, performing special effect processing again and then previewing the special effect for the user until the user finds the satisfied special effect.
It should be noted that, in this embodiment, the other path of video data is always in a circular playing state, that is, the video data starts to be played again after being played once, and the playing process may be paused to provide time for the user to select a special effect, or the user may control to start playing again after the user selects a new special effect. In the process of the circular playing, a user can select a special effect from the special effect selection window according to the preference to add the special effect to the video, the playing effect of the video is observed, if the user is unsatisfied with the effect, the special effect can be selected again to be processed, and then the video is played again until the user selects the target special effect. Most of the existing video special effect processing modes are that before a user starts to record a video, the user selects a special effect and previews the special effect, and when the user selects the special effect, the recording is started again, and the recording mode cannot provide a real-time effect for the user to preview the special effect.
Further, the special effect processing includes basic effect processing, and/or filter effect processing, and/or background effect processing.
Wherein, the basic effect processing comprises noise reduction, brightness, chroma and the like; filter effect processing includes the use of filters of various effects, such as: sketch, negative film, soft film, black and white film, etc.; the background effect processing includes the addition of various backgrounds, such as a weather background, a starry sky background, and the like. In addition, the special effect processing further includes adding various pendants to the video or realizing special effects of picture deformation, such as adding a special effect of wearing glasses, adding a special effect of face deformation, and the like, and this embodiment is not limited.
Step S103: after the video recording is finished, the initial video data is subjected to special effect processing according to the target special effect, and the obtained special effect video is encoded and then stored.
Specifically, the instruction for completing the video recording may be manually controlled by the user, for example, the user manually clicks the record ending button to end the video recording, or may automatically end the video recording, for example, when the video recording time reaches the preset time, the video recording is automatically ended, and this embodiment does not limit the video recording ending control manner. After the video recording is finished, the initial video data can be subjected to special effect processing according to the target special effect selected by the user, and the special effect video is coded and stored to finish the recording and storage of the special effect video.
In this embodiment, the step S103 specifically includes:
1. and after the video recording is finished, acquiring each frame of image of the initial video data.
Specifically, after the video recording is completed, the initial video data is divided according to the frame rate to obtain multiple frames of images, and then the multiple frames of images are sequentially arranged according to the time sequence.
2. And acquiring a special effect processing template corresponding to the target special effect.
Specifically, the special effect processing is usually performed in the presence of a corresponding template processing manner, for example, a beautifying special effect, which generally includes buffing, face thinning, and the like, wherein the buffing and face thinning are mainly performed on the face of the person. The special effect processing template is a processing object and a processing mode for recording a special effect.
3. And identifying the area needing special effect processing in each frame of image according to the special effect processing template.
Specifically, after a special effect processing template corresponding to a target special effect is acquired, determining a region needing special effect processing, such as a beautifying special effect, according to the special effect processing template, wherein the region needing processing is a face region, and a face in an image needs to be identified, and then beautifying the face; as another example, a starry sky background, which requires identifying a sky region in an image and filling the sky region with a starry sky special effect.
4. And carrying out special effect processing on the region according to the target special effect to obtain a special effect video, and coding and storing the special effect video.
Specifically, after confirming a target special effect and a region of each frame of image needing special effect processing, sequentially carrying out special effect processing on the region of each frame of image according to the sequence of each frame of image until each frame of image is processed, obtaining a special effect video, and then coding and storing the special effect video.
Further, the step of performing special effect processing on the other path of video data according to the special effect selected by the user in step S102 specifically includes: and carrying out low-precision special effect processing on the other path of video data according to the special effect.
Specifically, in order to avoid an excessive load on hardware when generating a preview video, in this embodiment, when processing another path of video data according to a special effect, a low-precision special effect process is performed by omitting edge or detail processing, so as to reduce resources occupied by calculation and avoid an excessive hardware load in a video recording process.
The step S103 of performing special effect processing on the initial video data according to the target special effect specifically includes: and carrying out high-precision special effect processing on the initial video data according to the target special effect.
Specifically, after the video recording is finished, the mobile terminal does not need to generate the preview video any more, and at this time, the processing of the edge and the detail can be emphasized, so that the finally generated special effect video has a better effect.
The special effect video recording method of the first embodiment of the invention divides the recorded video data into two paths, wherein one path is taken as initial video data to be cached in a buffer pool, the other path of video data is subjected to special effect processing and then previewed by a user, after the video recording is finished, the initial video data is processed according to the target special effect selected by the user, the special effect video is obtained and then coded and stored, the process of video recording and previewing and the process of video coding and storing are separately executed, so that when the video is recorded, the operation of video previewing is only needed, and the video coding and storing process is executed after the video recording is finished, thereby reducing the pressure of the video recording process on hardware, reducing the load of a mobile terminal and avoiding the situation of blocking.
Fig. 2 is a flowchart illustrating a special effect video recording method according to a second embodiment of the present invention. It should be noted that the method of the present invention is not limited to the flow sequence shown in fig. 2 if the results are substantially the same. As shown in fig. 2, the method comprises the steps of:
step S201: when the video recording starts, the obtained video data is divided into two paths, and one path of video data is stored as initial video data.
In this embodiment, step S201 in fig. 2 is similar to step S101 in fig. 1, and for brevity, is not described herein again.
Step S202: and acquiring the special effect selected by the user.
Specifically, before displaying the preview video with the added special effect, the special effect selected by the user needs to be obtained, wherein the way in which the user selects the special effect can be selected by clicking the special effect provided in the special effect selection window.
Further, in order to further improve user experience, a short video may sequentially perform special effect processing using a plurality of special effects, and therefore, the obtaining of the special effect selected by the user specifically includes:
at least one special effect selected by a user and the effective time corresponding to each special effect are obtained.
It should be noted that, when setting a special effect, the set special effect data is not limited, and a user can select a plurality of special effects to add to the video according to the requirement. It should be understood that, according to the type division, the special effects can be divided into a special effect that can be displayed simultaneously and a special effect that cannot be displayed simultaneously, for example, the starry sky background special effect and the eye pendant special effect can be inserted into the same video and displayed simultaneously, while the rainy day background special effect and the starry sky background special effect cannot be displayed simultaneously, and the current eye pendant special effect and the other eye pendant special effect cannot be displayed simultaneously.
In this embodiment, the display time of the plurality of special effects is limited by the effective time point. Specifically, when at least one special effect selected by a user is obtained, an effective time point corresponding to each special effect needs to be obtained at the same time, where the effective time points include a start effective time point and an end effective time point, for example, when the user selects the special effect including a starry sky background special effect and a rainy day background special effect, the effective time of the starry sky background special effect and the effective time of the rainy day background special effect cannot be overlapped, so that a conflict is avoided. The effective time is determined according to the playing progress of the other path of video data, for example, a starry sky background special effect is adopted in the first 15 seconds of the other path of video data, the effective time is 0-15 seconds, a rainy day background special effect is adopted in the 15 th-30 th seconds, the effective time is 16-30 seconds, an eye hanging special effect is adopted in the whole playing process, and the effective time is 0-30 seconds.
Further, in some embodiments, the step of obtaining the special effect selected by the user specifically includes:
1. a gesture motion or a facial motion of the user is recognized.
2. And acquiring special effects matched with the gesture actions or the facial actions from the special effect library.
Specifically, the special effect is bound with the gesture action or the facial action in advance, and when the gesture action or the facial action of the user acquired by the camera is matched with the preset gesture action or the facial action, the special effect corresponding to the gesture action or the facial action is acquired, so that the user does not need to manually select the special effect, and the user operation is more convenient.
Step S203: and playing the other path of video data, and performing special effect processing on the other path of video data according to the special effect to generate the current preview video.
Further, when the user selects a plurality of special effects, another path of video data is played, and special effect processing is performed on the other path of video data according to the special effects to generate a current preview video, which specifically includes the steps of: and playing the other path of video data, and performing special effect processing on the other path of video data within the corresponding effective time according to the special effect to generate the current preview video.
Specifically, when another path of video data starts to be played, the current playing time is confirmed, the special effect corresponding to the current time point is confirmed according to the current playing time, and then the other path of video data is processed according to the special effect and then output and displayed.
Step S204: and receiving an instruction fed back by a user, and judging whether the instruction is a confirmation instruction or a replacement instruction. If the command is a confirm command, go to step S205; if the command is a replacement command, step S206 is executed.
The instructions fed back by the user include a confirmation instruction and a replacement instruction, wherein the confirmation instruction is used for confirming the target special effect selected by the user, and the replacement instruction is used for replacing the special effect. Specifically, after a current preview video is displayed to a user, the user evaluates the preview video to determine whether the preview video meets requirements, and then receives a command fed back by the user. Further, in some embodiments, the instruction further includes a modification instruction and a removal instruction, wherein the modification instruction is used for modifying the relevant parameter of the special effect, for example, for the face-thinning special effect, the degree of face thinning can be manually set by the user; the removing instruction is used for removing the special effect from the current prediction video and restoring the special effect to the original video.
Further, in some embodiments, the user may feedback the instruction by gesture, voice or expression, and different gestures correspond to different instructions, for example: the confirmation instruction and the like are expressed by inputting a voice of "confirmation", and the present embodiment is not limited.
Step S205: and taking the special effect as a target special effect.
Step S206: and processing another path of video data according to the special effect selected by the user again to generate a new preview video, and executing the step S204 again.
Specifically, when the instruction fed back by the user is a replacement instruction, a special effect specified again by the user is confirmed according to the replacement instruction, and then another path of video data is reprocessed according to the special effect to generate a new preview video.
Step S207: after the video recording is finished, the initial video data is subjected to special effect processing according to the target special effect, and the obtained special effect video is encoded and then stored.
In this embodiment, step S207 in fig. 2 is similar to step S103 in fig. 1, and for brevity, is not described herein again.
The special effect video recording method of the second embodiment of the invention is based on the first embodiment, by providing a channel for selecting special effects for users, the users can select favorite special effects at any time for previewing, the mode of selecting the special effects can be identified by gesture action or face action, the operation mode is diversified, and the effective time can be set for the special effects, so that a plurality of special effects can be added to one video, and the addition of a plurality of special effects of the same type to one video can not generate conflict by the division of the effective time.
