The video recording method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.
Referring to fig. 1, an embodiment of the present application provides a video recording method applied to an electronic device, and as shown in fig. 1, the method includes the following steps:
and 103, taking the first picture as a frame picture of the recorded video.
Here, under the condition that the electronic device starts a video recording mode, the electronic device may determine a zoom multiple of any time point in a video recording process through a time point and a zoom multiple in each coordinate point on a target curve, that is, the zoom multiple (that is, a first zoom multiple) of a currently recorded time point (that is, a first time point) is a zoom multiple in the coordinate point where the currently recorded time point is located, so that the zoom multiple in the video recording process may be adjusted according to the target curve.
In step 101, in a case that the electronic device displays a video recording preview interface, the electronic device may receive a first input of a user on the video recording preview interface, and start a video recording mode and acquire a target curve in response to the first input.
In the embodiment of the application, the electronic device may display the video recording preview interface, where the electronic device responds to an input indicating that the video recording preview interface is displayed when the electronic device receives the input.
The input for instructing to display the video recording preview interface may be at least one of voice input, space gesture input, touch input, and the like.
For example, it may be that the electronic device receives a touch input by a user clicking an icon of a camera application, and a video recording preview interface is displayed in response to the touch input, as shown in fig. 2.
In addition, the first input may be any input for instructing to start a video recording mode, and may be at least one of a voice input, an air gesture input, a touch input, and the like.
For example, as shown in fig. 3, if the electronic device receives a click input (i.e., a first input) from a user on the video recording button 31 in the video capture preview interface, the electronic device starts the video recording mode.
It should be noted that, the electronic device starts the video recording mode, which may be understood as that the electronic device takes the time point of starting the video recording mode as the starting time, shoots the starting time and each frame image after the starting time as time advances, and generates a recorded video through all the shot frame images, that is, the recorded video is composed of all the shot frame images.
In this embodiment, when the electronic device receives the first input and starts the video recording mode, the electronic device may further obtain the target curve in response to the first input.
The electronic device may obtain the target curve, where at least one curve is preset in the electronic device, and the electronic device may determine, in response to the first input, one curve among the at least one curve as the target curve.
The determining of one curve among the at least one curve as the target curve may be that the electronic device determines a curve indicated by an input of a user as the target curve.
For example, as shown in fig. 3, in a case where the electronic device receives a click input of a user on the video recording button 31 in the video photographing preview interface, the electronic device displays a floating frame in which at least one curve is displayed in the video photographing preview interface, and in a case where the electronic device receives a click input of curve 1 in the at least one curve, the electronic device determines curve 1 as the target curve.
Or, to reduce the user's operations during the video recording process, the electronic device may automatically determine one curve among the at least one curve as the target curve, and specifically, the obtaining the target curve may include:
acquiring scene information of the electronic equipment;
and determining a curve matched with the scene information in the plurality of curves as a target curve.
Here, the electronic device can determine the target curve matched with the scene information in the plurality of curves according to the scene information, so that the selected target curve can be matched with the scene of the video recorded by the electronic device, the input of a user can be reduced, and the operation convenience of video recording is improved.
The scene information may be any information associated with a scene where the electronic device currently records the video, for example, the scene information may include at least one of a location, a time, a sound, an environmental parameter, and the like.
For example, when a user records a dance video by using an electronic device, the electronic device may acquire a music segment within 5 seconds after the start of the video recording mode when the electronic device receives a first input from the user and starts the video recording mode, determine an audio file played during recording the dance video according to the acquired music segment, and determine a curve having a correspondence relationship with the played audio file in at least one curve as the target curve.
Of course, the target curve may be a curve generated before the first input is received, and the target curve may be generated by the electronic device according to an input of a user.
In this embodiment of the application, to meet an actual requirement of a user, the target curve may be a curve drawn by the user through input, and specifically, before starting video recording and acquiring the target curve, the method may further include:
under the condition that the video recording preview interface receives a second input, responding to the second input, and displaying a curve drawing interface;
in a case where a third input at the curve-drawing interface is received, a target curve drawn by the third input is displayed in the curve-drawing interface.
Here, the electronic device may implement the drawing of the target curve according to the input of the user on the curve drawing interface, so that the generation of the target curve may meet the actual requirements of the user.
The second input may be any input for instructing the electronic device to display a curve drawing interface, and may be at least one of a voice input, an air gesture input, and a touch input.
For example, as shown in fig. 4, in a case where the electronic device displays a video recording preview interface, if the electronic device receives a click input of a user to a button 41 in the video recording preview interface, the electronic device displays a curve drawing interface, as shown in fig. 5.
In addition, the curve drawing interface may be any display interface for the user to input the third input. For example, the above-described curve drawing interface may be a display interface that displays a time-zoom-multiple coordinate system whose abscissa is time and whose ordinate is a zoom multiple.
In this embodiment of the application, when the electronic device displays the curve drawing interface, if the electronic device receives the third input, the electronic device may generate and display a target curve drawn by the third input.
The third input may be any input for drawing a curve in the curve drawing interface, for example, the third input may be a slide input for inputting a slide trajectory in the curve drawing interface as a curve, and the like.
The electronic device may generate the target curve according to a third input, for example, the electronic device may receive a slide input by a user in a time-zoom multiple coordinate system of the curve drawing interface, and the electronic device may set a curve of a slide trajectory of the slide input in the time-zoom multiple coordinate system as the target curve.
Or, in order to make the target curve generated by the electronic device have higher precision and more convenient operation, after the curve drawing interface is displayed, the method may further include:
under the condition that a fourth input in the curve drawing interface is received, responding to the fourth input, starting a curve drawing mode, and displaying a zoom factor adjusting mark on the curve drawing interface;
the displaying the target curve drawn by the third input in the curve drawing interface may include:
generating a first coordinate point if a third input is received at a second time point after the curve-drawing mode is turned on, wherein the third input includes: starting any time point after the curve drawing mode, and adjusting the input of the zooming multiple on the zooming multiple adjusting mark; the first coordinate point comprises a second time point and a second zoom multiple, and the second zoom multiple is a zoom multiple adjusted by the third input at the second time point;
and taking the first coordinate point as a coordinate point on a target curve, and displaying the target curve, wherein the target curve consists of coordinate points generated in a time period from the starting of the curve drawing mode to the second time point.
Here, the electronic device may be configured to, after the curve drawing mode is started, adjust the zoom multiple of each time point on the zoom multiple adjustment flag according to a third input, generate a coordinate point corresponding to each time point after the curve drawing mode is started, and form the target curve through the generated coordinate point, so that the user only needs to adjust the zoom multiple of each time point according to the advancement of time in the process of drawing the target curve, so that the user's input is more convenient and controllable, and the convenience of drawing the target curve and the accuracy of drawing the target curve by the electronic device are further improved.
The fourth input may be any input for instructing to start the curve drawing mode, and may be at least one of a voice input, an air gesture input, a touch input, and the like.
For example, as shown in fig. 5, when the electronic device displays a curve drawing interface, the electronic device starts the curve drawing mode when the electronic device receives a click input of a user on a button 51 of the curve drawing interface.
In addition, the zoom factor adjusting identifier may be any identifier displayed in the curve drawing interface and used for adjusting the zoom factor, for example, the zoom factor adjusting identifier may be a slide rail displayed in the curve drawing interface and a slide block displayed on the slide rail, and a user may adjust the zoom factor by dragging the slide block to slide along the slide rail; alternatively, as shown in fig. 5, the electronic device displays an arrow dotted line 52 in its curve drawing interface, and if the user slides a greater distance in the direction indicated by the arrow, the zoom factor of the adjustment is greater; otherwise, the smaller the zoom factor is adjusted.
In this embodiment of the application, the generating the first coordinate point may be that when the electronic device starts the curve drawing mode, the electronic device starts timing, that is, a time point at which the curve drawing mode is started is taken as an initial time point (for example, 0), and as time advances, the electronic device may determine, according to a zoom multiple (that is, a second zoom multiple) adjusted by a third input received at a current time point (that is, a second time point), a zoom multiple of a coordinate point (that is, a first coordinate point) corresponding to the current time point as the zoom multiple adjusted by the third input at the current time point.
In addition, the electronic device may generate a target curve including all the coordinate points from the initial time point to the second time point by using the first coordinate point as a coordinate point on the target curve when generating the first coordinate point.
For example, as shown in fig. 6, the electronic device receives a slide input from the user in the direction of the arrow dashed line 52 at the current time point, and takes the zoom factor adjusted by the slide input as the zoom factor in the coordinate point corresponding to the current time point, so that the electronic device can generate a curve 61 (i.e., a target curve) in its curve drawing interface as time advances.
It should be noted that, in the process of drawing the target curve, since the length of the curve segment that can be displayed on the curve drawing interface of the electronic device is limited, the displaying the target curve may include: and displaying a part of curve of the target curve on the curve drawing interface.
For example, the electronic device generates a target curve within a time period of 0 to 3s, and only the curve with the time length of 1.5s can be displayed in the curve drawing interface, so when the electronic device generates the target curve at the current time of 3s after the curve drawing mode is turned on, the electronic device only displays a part of the curve generated within the time period of 1.5s to 3s of the target curve on the curve drawing interface, and moves a part of the curve generated within the time period of 0 to 1.5s as shown in fig. 6 out of the screen, as shown in fig. 7.
In this embodiment of the application, to improve operation convenience in a video recording process, the target curve may also be a curve automatically generated according to a user instruction before the first input is received. Specifically, before starting video recording and acquiring the target curve, the method may further include:
under the condition that a fourth input is received by the video recording preview interface, responding to the fourth input, and displaying an audio file list, wherein the audio file list comprises at least one audio file identifier;
under the condition that a fifth input in the audio file list is received, generating and displaying the target curve based on a first audio file, wherein the first audio file is as follows: the fifth input is an audio file corresponding to the identifier indicated in the identifier of the at least one audio file.
The electronic equipment can generate the target curve according to the audio file selected by the user in the audio file list, and the user does not need to input operation of drawing the curve in the process of generating the target curve, so that the operation amount of the user is reduced, and the operation convenience of the electronic equipment and the efficiency of generating the target curve are improved.
The fourth input may be any input for instructing to display the audio file list, and may be at least one of a voice input, an air gesture input, a touch input, and the like.
For example, as shown in fig. 4, in a case where the electronic device displays a video recording preview interface, if the electronic device receives a click input (i.e., a fourth input) from a user to a button 41 in the video recording preview interface, the electronic device displays the audio file list 1, where the audio file list 1 includes an audio a option, an audio B option, an audio C option, and the like, as shown in fig. 8.
In addition, the fifth input may be any input for an audio file selected in the audio file list, and may be at least one of a voice input, a space gesture input, a touch input, and the like.
For example, as shown in fig. 8, if the electronic device receives a click input (i.e., a fifth input) by which the user clicks an option of the audio file B, the electronic device determines the audio file B as the first audio file.
In this embodiment of the application, after the electronic device determines the first audio file, the electronic device may generate and display the target curve based on the first audio file.
The generating of the target curve based on the first audio file may be that the electronic device acquires a loudness oscillogram of the first audio file, and generates the target curve based on the loudness oscillogram of the first audio file. Here, the waveform in the loudness waveform diagram represents the intensity of music when the audio file is played, so that a stronger loudness can be set to correspond to a larger zoom factor, so that the recorded video has stronger impact.
It should be noted that, the target curve is generated based on the loudness waveform map of the first audio file, and an edge curve of a waveform in the loudness waveform map may be directly determined as the target curve.
However, because the loudness in the loudness oscillogram of the audio file may change too frequently, and the zoom factor in the target curve generated in this way also changes frequently, in order to avoid too frequent adjustment of the zoom factor in the recorded video, a smoother curve may be generated by the loudness oscillogram as the target curve.
Specifically, the generating and displaying the target curve based on the first audio file includes:
obtaining a loudness oscillogram of the first audio file;
and generating and displaying the target curve based on the envelope of the loudness wave form diagram.
Here, the electronic device may generate the target curve based on the envelope of the loudness oscillogram of the first audio file, so that the target curve generated based on the loudness oscillogram is smoother, the adjustment frequency of the zoom multiple in the video recording process may be reduced, and the quality of the recorded video may be improved.
For example, as shown in fig. 9(a), for the loudness oscillogram of the audio B acquired by the electronic device, the electronic device may take the envelope of the loudness oscillogram of the audio B, generate a smooth curve 91 as shown in fig. 9(B), and determine the curve 91 as the target curve.
In this embodiment of the application, after the electronic device starts the video recording mode and acquires the target curve, the electronic device may record a video based on the target curve, that is, at any time point after the video recording mode is started, a zoom multiple of a coordinate point corresponding to the time point is acquired on the target curve as a zoom multiple (i.e., a first zoom multiple) for shooting a current frame image, so that the zoom multiple is adjusted in a video recording process.
It should be noted that, in the process of performing video recording by the electronic device based on the target curve, the target curve may be displayed in a video recording interface, and a time point indicator may also be displayed, where the time point indicator is used to indicate a position of a current time point in the target curve.
For example, as shown in fig. 3, after the electronic device starts a video recording mode and acquires a target curve, the electronic device displays a video recording interface, as shown in fig. 10(a), and displays a curve 101 (i.e., the target curve) and a corner mark 102 for time point indication (i.e., a time point indicator) in a semi-transparent manner in the video recording interface, where an initial position of the corner mark 102 is a starting time point T0 of the curve 101, and the zoom factor is 0.9 times;
as time advances, the time point indication corner mark 102 moves to position 1 in a direction parallel to the time axis of the curve 101, and the time point indication corner mark 102 indicates a time point T1 of the curve 101 at which the zoom magnification is 3.0 times, as shown in fig. 10(b), the image of the person captured at the time point T1 is larger than the image of the person captured at the time point T0;
as time further advances, the time point indication corner mark 102 moves to position 2 in a direction parallel to the time axis of the curve 101, and the time point indication corner mark 102 indicates a time point T2 of the curve 101 at which the zoom factor is 1.5 times, as shown in fig. 10(c), the image of the person captured at the time point T2 is smaller than the image of the person captured at the time point T1;
as time advances again, the time point indication corner mark 102 moves to position 3 in a direction parallel to the time axis of the curve 101, and the time point indication corner mark 102 indicates the time point T3 of the curve 101 at which the zoom factor is 4.0 times, as shown in fig. 10(d), the image of the person captured at the time point T3 is larger than the image of the person captured at the time point T2.
In addition, when the electronic device starts the video recording mode and acquires the target curve, the electronic device may use any time point on the target curve as a start time point of video recording (i.e., a time point at which the video recording mode is started), and is not limited again.
In this embodiment of the application, in a process of recording a video based on the target curve by the electronic device, the target curve may be fixed and unchanged.
Certainly, in the process of recording a video, a situation that a user needs to adjust a target curve to change a zoom multiple corresponding to a time point after a current time point may occur, and to meet an adjustment requirement of the user on the target curve, after the target curve is obtained, the method may further include:
if a sixth input for adjusting a first curve segment in the target curve is received, updating the first curve segment to a second curve segment adjusted by the sixth input;
wherein, in the case that the first time point is the time point of the first curve segment, the first zoom multiple is the zoom multiple of the second curve segment at the first time point.
Here, the electronic device may adjust a part of the curve segment in the target curve according to the input (i.e., the sixth input) of the user, and change the zoom multiple corresponding to the time point in the part of the curve segment is realized, so that the actual requirement of the user may be met, and the user experience effect may be improved.
It should be noted that the sixth input may be any input for adjusting a portion of the curve segment in the target curve, and may be at least one of a voice input, an air gesture input, a touch input, and the like.
For example, as shown in fig. 11, in a case that the curve 101 is displayed in a video recording interface of the electronic device, if the electronic device receives a sliding input (i.e., a sixth input) from the user at the position 111 along a direction indicated by a dashed arrow, the electronic device adjusts a curve segment (i.e., a first curve segment) where the position 111 is located, so that the adjusted curve 101 is updated to a curve 112, and the curve 112 includes a curve segment (i.e., a second curve segment) where the curve segment where the position 111 is located is adjusted, as shown in fig. 12.
It should be noted that, in the video recording method provided in the embodiment of the present application, the execution main body may be a video recording apparatus, or a control module of the video recording apparatus for the method of video recording. In the embodiment of the present application, a video recording apparatus is taken as an example to execute a video recording method, and the video recording apparatus provided in the embodiment of the present application is described.
