控制方式实施例Control mode embodiment
为了解释具体的控制实现方式，本实施例阐述了两种情况下的具体实现为例进行阐述In order to explain the specific control implementation manner, this embodiment describes the specific implementation in two cases as an example.
1.选用音频模组对录制过程实现控制1. Select audio module to control the recording process
已知，音乐的基本元素包括音的高低、音的长短、音的强弱和音色。通过这些基本元素，从而形成一首歌的节奏，曲调，旋律等。图5是本发明实施例的控制方式示意图，如题图5所示，通过接收并分析音乐的旋律节奏特征与强度振幅特征，处理获得控制信号，通过音乐强弱的变化控制录制的焦距变化，通过旋律节奏的快慢变化来控制图像录制时的帧率变化。It is known that the basic elements of music include the level of the sound, the length of the sound, the strength of the sound, and the tone. Through these basic elements, the rhythm, tune, melody, etc. of a song are formed. FIG. 5 is a schematic diagram of a control mode according to an embodiment of the present invention. As shown in FIG. 5, by receiving and analyzing the melody rhythm feature and the intensity amplitude feature of the music, the control signal is obtained, and the recorded focal length change is controlled by the change of the music intensity. The speed of the melody rhythm changes to control the frame rate change during image recording.
旋律快慢和音乐振幅的信号识别方式：通过对音频信息最大响度的识别，获取音乐振幅。通过对两个最大振幅的间隔进行计时从而获取音乐的旋律长度。The signal recognition method of melody speed and music amplitude: the music amplitude is obtained by recognizing the maximum loudness of the audio information. The melody length of the music is obtained by timing the intervals of the two maximum amplitudes.
2.选用模板参数对录制过程进行控制 2. Use the template parameters to control the recording process
自定义或者预设模板可以通过对时间轴的控制数据对录制进行控制。例如，在时间轴上规定，在某些时间段利用低帧率拍摄，在某些时间段利用高帧率拍摄。Custom or preset templates can control recording by controlling data on the timeline. For example, it is stipulated on the time axis that shooting is performed at a low frame rate for certain periods of time and at a high frame rate for certain periods of time.
最终，在录制完成后，终端设备通过固定帧率播放录制的视频，展现出的将是具有实时变化的录制效果。Eventually, after the recording is completed, the terminal device plays the recorded video at a fixed frame rate, which will show a recording effect with real-time changes.
视频输出合成实施例Video output synthesis embodiment
由于在录制时使用变化的帧率录制，如果同步利用变化帧率来录制场景声音，最终呈现的音效将非常不好。因此，在最终视频合成过程中，将音频信息独立出来，将播放的音乐数据与正常帧率播放的视频数据进行合成，最终导出视频数据。Since recording is performed at a variable frame rate while recording, if the scene sound is recorded using the varying frame rate in synchronization, the resulting sound will be very bad. Therefore, in the final video synthesis process, the audio information is separated, and the played music data is synthesized with the video data played at the normal frame rate, and finally the video data is derived.
图6是本发明实施例的视频输出合成示意图，如图6所示，描述了后期视频合成的实现方法。FIG. 6 is a schematic diagram of video output synthesis according to an embodiment of the present invention. As shown in FIG. 6, a method for implementing post-video synthesis is described.
***交互方法实施例System interaction method embodiment
以下以一个具体事例来说明用户在一般场景下如何利用本***的发明实现多变化的视频录制，终端则以手机为例。The following is a specific example to illustrate how the user can use the invention of the system to realize multi-variable video recording in a general scenario, and the terminal uses a mobile phone as an example.
图7是本发明实施例的***交互方法示意图，首先，需要手机进入拍摄软件中，通过滑动选择进入多变化的视频录制，此时手机的处理控制***已经激活摄像头，并等待拍摄控制信号输入；在用户界面上有4个选择项，“自定义”、“模板”、“音频控制”、“麦克风(即外部音频控制)”；当用户选择音频模式，如果此时手机已经打开了音乐软件将可以直接进入变化录制，否则将跳转进音乐软件界面点击播放再返回开始录制；当用户选择外部音频模式，将打开麦克风接收周边的环境音效实现录制；当用户选择默认模式，将调用***自带的简单变化模板进行拍摄；当用户选择自定义选项，将允许用户对默认参数进行调节达到自己需要的效果参数再进行拍摄。7 is a schematic diagram of a system interaction method according to an embodiment of the present invention. First, a mobile phone is required to enter a shooting software, and a sliding change is selected to enter a multi-variable video recording. At this time, the processing control system of the mobile phone has activated the camera and waits for the shooting control signal input; There are 4 options on the user interface, "custom", "template", "audio control", "microphone (ie external audio control)"; when the user selects the audio mode, if the phone has already opened the music software You can directly enter the change recording, otherwise it will jump into the music software interface, click play and then return to start recording; when the user selects the external audio mode, the microphone will be turned on to receive the surrounding ambient sound effect for recording; when the user selects the default mode, the system will be called. The simple change template is used for shooting; when the user selects the custom option, the user will be allowed to adjust the default parameters to achieve the desired effect parameters and then shoot.
应用场景实施例Application scenario
在播放音乐的情况下使用 Use when playing music
用户在拍照APP中进入变化摄像模式，主界面会提示用户使用那种模式，音频模式，可以选择使用自己终端内不放的软件，也可以选择使用室外场景音效进行控制，那个时候可以通过接收房间内播放的音效进行录制。The user enters the change camera mode in the photo app. The main interface prompts the user to use that mode. The audio mode can be selected to use the software in the terminal, or the outdoor scene sound can be used for control. At that time, the user can receive the room. The sound played inside is recorded.
使用预设模板拍摄Shoot with preset templates
利用预设模板又可以有两种情况实现：在播放音乐时，***自动识别音乐，找到相匹配的预设模板；或者单纯利用固定模板拍摄，事后，使用者可以添加上自己喜欢的音乐。With the preset template, there are two situations: when playing music, the system automatically recognizes the music and finds the matching preset template; or simply uses the fixed template to shoot, afterwards, the user can add his favorite music.
利用自定义方法进行变化视频录制Custom video recording with custom methods
假设需要拍摄一个例如好莱坞大片英雄登场的快慢镜头切换的场景，只需要在自定义模式下设定录制的时间轴帧率是快慢间隔的。例如，时间间隔以2秒为单位，20帧和45帧间隔进行拍摄，最终视频通过30帧的速度进行播放。Suppose you need to shoot a scene such as a Hollywood blockbuster's fast and slow shot switching. You only need to set the recorded timeline frame rate in the custom mode to be fast and slow. For example, the time interval is measured in units of 2 seconds, 20 frames and 45 frames, and the final video is played at a speed of 30 frames.
可选的，本实施例还可以包括以下方案，方案1：录制视频再后期处理的视频录制模式。这个替代方案，可以实现录制高帧率的视频，通过对该视频的后期处理，实现变换的录制效果。高帧率的用处在于，正常帧率被拉伸的话，视频的效果会受到影响，因此全视频都利用高帧率，可以提供更多的后期处理空间。方案2：一种可以实施进行手动快速变焦与变帧控制的录制模式。通过手机等终端的交互界面，在录制情况下实时调控相关拍摄数据实现多变化的视频录制。Optionally, the embodiment may further include the following solution: Option 1: Recording a video and then post-processing the video recording mode. This alternative solution enables recording of high frame rate video and post-processing of the video to achieve a converted recording effect. The use of high frame rate is that if the normal frame rate is stretched, the effect of the video will be affected, so the full video uses a high frame rate, which can provide more post-processing space. Option 2: A recording mode that can be implemented for manual fast zoom and variable frame control. Through the interactive interface of the terminal such as a mobile phone, real-time control of relevant shooting data in the case of recording enables multi-variation video recording.
