Fig. 2 is a flowchart of a video recording method according to an embodiment of the present invention. The execution subject of the embodiment of the present invention is a terminal, and referring to fig. 2, the method includes:
201. and when receiving the recording instruction, the terminal collects the audio data and the image of the target object in real time.
Wherein, the recording instruction is used for indicating audio data and images when the recording target object sing the target song; in this step, when the terminal receives the recording instruction, the terminal starts a camera and an audio acquisition device to start to acquire the image and audio data of the target object in real time. The target object can trigger a recording instruction of the terminal in the video application: when the video application is opened, the terminal may display a plurality of song identifications for a plurality of alternative songs on the current interface. When the terminal detects that any song identification is selected, the terminal receives the recording instruction.
When the terminal receives the recording instruction, the terminal can also acquire the accompaniment audio of the target song and play the accompaniment audio of the target song, the target object can sing the target song along with the accompaniment audio, and the terminal collects the audio data and the image of the target object in real time in the process of singing the target song by the target object. In addition, the terminal can also display the lyrics of the target song in the current interface.
202. The terminal generates a first audio file in a first file format according to the collected audio data.
In this step, the terminal creates a first audio file, encodes the acquired audio data according to a first file format of the first audio file, and writes the encoded audio data into the first audio file.
The first Audio file may be an MP3(Moving Picture Experts Group Audio Layer III) Audio file.
In a possible implementation, the terminal may also filter out noise in the audio data. Correspondingly, the steps can also be as follows: the terminal carries out noise reduction processing on the acquired audio data through a preset noise reduction algorithm, and writes the audio data subjected to noise reduction processing into the first audio file.
It should be noted that, when the terminal collects the audio data, the MP3 audio file is generally generated first, and since the MP3 audio file has a small compression on the audio data, when the MP3 audio file is played, the sound quality is not significantly reduced, and the storage space occupied by the MP3 audio file is small, so that on the premise of ensuring the playing fluency, the storage space occupied by the file is saved to the maximum extent, and the system resource utilization rate of the terminal is improved. In addition, the terminal can also perform noise reduction processing on the acquired audio data, so that noise, noise and the like in the acquired voice are eliminated, and the recorded audio data is further ensured to have higher tone quality.
203. And when a sound special effect instruction is received, the terminal converts the first audio file into a second audio file.
The file format of the second audio file is a second file format matched with a sound special effect method adopted by sound special effect processing. The sound special effect method is a method for adding a sound special effect to the second audio file subsequently. In this step, the terminal converts the first audio file into a second audio file in a second file format according to the second file format.
The terminal can display a sound special effect adding button on a recording interface, when the terminal detects that the sound special effect adding button is triggered, the terminal can provide a plurality of alternative sound special effects, and then the sound special effects are added based on the sound special effects selected by a user. Wherein, the process can be as follows: the terminal displays a plurality of sound effect options on a recording interface, wherein each sound effect option corresponds to one type of sound special effect; when any sound effect option in the plurality of sound effect options is detected to be selected, the sound effect instruction is received, and the sound effect corresponding to the selected sound effect option is determined as the target sound effect.
Wherein, the second audio file is a PCM (Pulse Code Modulation) audio file.
As shown in fig. 3, the terminal may display a "sound effect" button in the upper right corner of the recording interface, and when the "sound effect" button is triggered, a plurality of sound effect options are displayed on the recording interface of the terminal, as shown in fig. 4, the plurality of sound effect options may include: electric sound effect, minions sound effect, phonograph sound effect, magic beasts sound effect, and the like. Of course, the sound effect option may also include an option to indicate that no sound effect is to be added.
It should be noted that, the terminal converts the first audio file into the second audio file, so that the terminal can perform subsequent processing of the sound special effect based on the audio file in the second file format. In addition, the second audio file can be a PCM audio file, audio data in the PCM audio file is not subjected to any coding and compression processing, compared with audio files in other formats, the tone quality of the audio data in the PCM audio file is higher, subsequent sound effect processing is performed on the basis of the PCM audio file, an audio file with better tone quality is obtained, and the accuracy of sound effect processing is improved.
204. And the terminal adds a target sound special effect in the second audio file according to the sound special effect instruction to obtain a third audio file.
In this step, the terminal performs sound special effect processing on the audio data in the second audio file through a target sound effect algorithm according to the sound special effect instruction, and generates the third audio file according to the audio data after the sound special effect processing.
The terminal can display a plurality of sound effect options on the interface, each sound effect option corresponds to one sound effect algorithm, and the terminal can store the sound effect algorithm corresponding to each sound effect option in advance. The target sound effect algorithm is a sound effect algorithm corresponding to the selected sound effect option in the sound effect options. And when a sound special effect instruction is received, the terminal takes a sound effect algorithm corresponding to the selected sound effect option as a target sound effect algorithm based on the selected sound effect option, and adds a target sound characteristic to the second audio file through the target sound effect algorithm to obtain a third audio file. Wherein the third audio file is also a PCM audio file.
The terminal can adjust the frequency, the tone and the like of the sound signal corresponding to the audio data through a target sound effect algorithm, so that the adjusted audio data are the sound meeting the personalized requirements of the user. For example, the user can add a sound special effect to make the sound of singing have the effects of a minions special effect, a telephone sound special effect and the like after being processed. In addition, the sound effect algorithm corresponding to each sound effect option may be any algorithm for realizing addition of a sound effect of a type corresponding to the sound effect option, and this is not specifically limited in the embodiment of the present invention. For example, the sound effect algorithm may be SOLA (Synchronized overlap-add method).
As shown in fig. 4, the terminal may display a plurality of sound effect options, and the user may select among the plurality of sound effect options, so that the terminal performs sound effect processing based on the personalized selection of the user.
In a possible implementation manner, the terminal may further perform sound effect processing on only a part of the audio data in the second audio file based on a user requirement, where the terminal may select a part of the audio data to be processed based on a time period corresponding to the audio data. Specifically, the steps may also be: the terminal displays the playing time length of the audio data in the second audio file in a sound effect adding interface, and the terminal determines the target audio data in the second audio file based on the selected target time interval in the playing time length. And the terminal adds the target sound special effect to the target audio data in the second audio file according to the sound special effect instruction to obtain the third audio file.
As shown in fig. 4, the terminal may display the playing time length of the audio data in the second audio file, the user may select the target audio data in the second audio file based on the playing time length, and the terminal performs sound effect processing based on the target audio data selected by the user.
It should be noted that the terminal can directly perform sound special effect processing on the PCM audio file, which solves the problem that the sound effect algorithm is not matched with the format of the audio file, so that the terminal can perform sound effect processing based on the PCM audio file with higher sound quality, and the applicability of the video recording method is improved.
205. And the terminal generates a video file according to the image and the third audio file.
In this step, the third audio file is also a PCM audio file. The terminal may convert the third audio file into a fourth audio file, and then generate the video file according to the acquired image and the fourth audio file. Wherein the fourth audio file is an MP3 audio file.
Furthermore, the terminal can also send the video file to a server, and the server sends the video file to a platform of the video application, so that more users can browse the video file, information exchange among multiple users is promoted, and the activity of the users on the application platform is improved.
It should be noted that the PCM audio file is a lossless compressed file, and generally occupies a large storage space, and is inefficient when being transmitted or played. In the step, when audio and video are stored, the audio data are stored as MP3 audio files, so that the size of the files is reduced to the maximum extent on the premise of guaranteeing smooth playing of the audio files, the storage space occupied by the files is reduced, and the cost required in the process of recording the video is saved.
To describe the technical process of the embodiment of the present invention more clearly, taking the whole technical process shown in fig. 5 as an example, a video recording process is introduced, as shown in fig. 5, when a terminal receives a recording instruction, the terminal collects audio data and images, and encodes the audio data into an MP3 audio file, when a user needs to add a sound special effect, the terminal converts an MP3 audio file into a PCM audio file based on the sound special effect instruction, and adds a target sound special effect selected by the user in the PCM audio file to generate a PCM audio file with the target sound special effect, and finally, the terminal also needs to convert the PCM audio file into an MP3 audio file, so as to facilitate subsequent file transmission and playing based on the MP3 audio file.
