其中，上述传感器模块180可以包括压力传感器，陀螺仪传感器，气压传感器，磁传感器，加速度传感器，距离传感器，接近光传感器，指纹传感器，温度传感器，触摸传感器，环境光传感器和骨传导传感器等传感器。
可以理解的是，本实施例示意的结构并不构成对电子设备100的具体限定。在另一些实施例中，电子设备100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
处理器110可以包括一个或多个处理单元，例如：处理器110可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processing unit，GPU)，图像信号处理器(image signal processor，ISP)，控制器，存储器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
控制器可以是电子设备100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。
可以理解的是，本实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对电子设备100的结构限定。在另一些实施例中，电子设备100也可以采用上 述实施例中不同的接口连接方式，或多种接口连接方式的组合。
电子设备100通过GPU，显示屏194，以及应用处理器等实现显示功能。GPU为图像处理的微处理器，连接显示屏194和应用处理器。GPU用于执行数学和几何计算，用于图形渲染。处理器110可包括一个或多个GPU，其执行程序指令以生成或改变显示信息。
显示屏194用于显示图像，视频等。该显示屏194包括显示面板。显示面板可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot light emitting diodes，QLED)等。
电子设备100可以通过ISP，摄像头193，视频编解码器，GPU，显示屏194以及应用处理器等实现拍摄功能。
ISP用于处理摄像头193反馈的数据。例如，拍照时，打开快门，光线通过镜头被传递到摄像头感光元件上，光信号转换为电信号，摄像头感光元件将所述电信号传递给ISP处理，转化为肉眼可见的图像。ISP还可以对图像的噪点，亮度，肤色进行算法优化。ISP还可以对拍摄场景的曝光，色温等参数优化。在一些实施例中，ISP可以设置在摄像头293中。
摄像头193用于捕获静态图像或视频。物体通过镜头生成光学图像投射到感光元件。感光元件可以是电荷耦合器件(charge coupled device，CCD)或互补金属氧化物半导体(complementary metal-oxide-semiconductor，CMOS)光电晶体管。感光元件把光信号转换成电信号，之后将电信号传递给ISP转换成数字图像信号。ISP将数字图像信号输出到DSP加工处理。DSP将数字图像信号转换成标准的RGB，YUV等格式的图像信号。在一些实施例中，电子设备100可以包括N个摄像头193，N为大于1的正整数。
示例性的，上述N个摄像头193可以包括：一个或多个前置摄像头和一个或多个后置摄像头。例如，以上述电子设备100是手机为例。手机包括至少一个前置摄像头。该前置摄像头配置于手机的前侧，如，图2中的(a)所示的前置摄像头201。另外，手机包括至少一个后置摄像头。该后置摄像头设置于手机的背侧。这样，前置摄像头和后置摄像头朝向不同的方向。
在一些实施例中，电子设备可以启用上述N个摄像头139中至少一个摄像头进行拍摄，并生成对应的照片或视频。例如，单独使用电子设备100的一个前置摄像头进行拍摄。再如，单独使用电子设备100的一个后置摄像头进行拍摄。再例如，同时启用两个前置摄像头进行拍摄。再例如，同时启用两个后置摄像头进行拍摄。再例如，同时启用一个前置摄像头和一个后置摄像头进行拍摄等。
可以理解的，单独启用一个摄像头139进行拍摄，可以称为启用了单摄模式，如，前摄模式(又称为单前模式)、后摄模式(又称为单后模式)。同时启用多个摄像头139进行拍摄，可以统称为启用了多摄模式，如，前前模式、前后模式、后后模式、画中画模式。
以同时启用一个前置摄像头和一个后置摄像头进行举例。在同时启用一个前置摄像头和一个后置摄像头进行拍照后，电子设备可以将前置摄像头和后置摄像头采集到的图像帧进行渲染合并。其中，上述渲染合并可以是将不同摄像头采集的图像帧进行拼接。如，采用前后模式进行竖屏拍照后，可以将不同摄像头采集的图像帧进行上下拼接。再如，采用后后模式进行横屏拍照后，可以将不同摄像头采集的图像帧进行左右拼接。再如，采用画中画模式进行拍照后，可以将一个摄像头采集到的图像帧镶嵌在另一个摄像头采集到的图像帧中。然后，进行编码，生成照片。
另外，在同时启用一个前置摄像头和一个后置摄像头进行视频拍摄后，前置摄像头采集一路视频流，并缓存。后置摄像头采集一路视频流，并缓存。然后，电子设备100对缓存的两路视频流逐帧进行渲染合并处理，也即，渲染合并两路视频流中采集时间点相同或匹配的视频帧。之后，进行编码，生成视频文件。
数字信号处理器用于处理数字信号，除了可以处理数字图像信号，还可以处理其他数字信号。例如，当电子设备100在频点选择时，数字信号处理器用于对频点能量进行傅里叶变换等。
视频编解码器用于对数字视频压缩或解压缩。电子设备100可以支持一种或多种视频编解码器。这样，电子设备100可以播放或录制多种编码格式的视频，例如：动态图像专家组(moving picture experts group，MPEG)1，MPEG2，MPEG3，MPEG4等。
NPU为神经网络(neural-network，NN)计算处理器，通过借鉴生物神经网络结构，例如借鉴人脑神经元之间传递模式，对输入信息快速处理，还可以不断的自学习。通过NPU可以实现电子设备100的智能认知等应用，例如：图像识别，人脸识别，语音识别，文本理解等。
音频模块170用于将数字音频信息转换成模拟音频信号输出，也用于将模拟音频输入转换为数字音频信号。音频模块170还可以用于对音频信号编码和解码。在一些实施例中，音频模块170可以设置于处理器110中，或将音频模块170的部分功能模块设置于处理器110中。扬声器170A，也称“喇叭”，用于将音频电信号转换为声音信号。这样，电子设备100可以播放音频数据，如，视频音乐等。
压力传感器用于感受压力信号，可以将压力信号转换成电信号。在一些实施例中，压力传感器可以设置于显示屏194。陀螺仪传感器可以用于确定电子设备100的运动姿态。当电子设备100静止时可检测出重力的大小及方向。还可以用于识别电子设备100姿态，应用于横竖屏切换等应用。触摸传感器，也称“触控面板”。触摸传感器可以设置于显示屏194，由触摸传感器180K与显示屏194组成触摸屏，也称“触控屏”。触摸传感器用于检测作用于其上或附近的触摸操作。触摸传感器可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
在用户使用电子设备拍摄的视频之后，可以通过操作电子设备的方式，对所拍摄的视频进行编辑，如，配置视频音乐、加入动画特效、添加转场特效等。这样，经过二次创造的视频会更加生动、丰富，也符合用户的创作意图。其中，添加转场特效不仅能让视频内容过渡更加自然，还能够使视频呈现的内容更加丰富。
然而，相关技术中，在视频中已有转场特效的情况下，如果用户手动更改原有转场特效，操作过程很复杂。如果用户不更改原有转场特效，那么原有转场特效就可能和用户选择的视频音乐风格不符合的问题。显然，在确保视频可观赏性的前提下，添加转场特效的人机交互效率。
针对这一问题，本申请实施例提供了一种视频数据的转场处理方法。下面以上述电子设备100是手机为例，对本申请实施例的方法进行说明。
如图2中的(a)所示，手机包括主界面。上述主界面，又称为桌面202。该主界面可以是手机解锁后显示的用户界面。上述主界面可以包括已安装应用程序(Application，APP)的图标，如，相机APP的图标203。
在一些实施例中，手机可以接收用户在主界面的操作，并启动该操作所指示的APP。示例性地，如图2中的(a)所示，手机可以接收用户对图标203的操作，如点击操作，并响应于该操作，启动相机APP。在相机APP启动之后，可以显示相机APP所提供的应用界面。例如，显示用于执行拍摄功能的取景界面，也即，如图2中的(b)所示的界面204。
在一些实施例中，用户可以在界面204中切换相机APP的不同功能模式，如，人像功能模式、拍照功能模式、录像功能模式和多镜录像功能模式等。也就是，手机可以接收用户在界面204中的操作1，该操作1用于指示相机APP切换不同的功能模式。
示例性地，在界面204中包括相机APP的多个功能模式所对应的控件，如，人像控件、拍照控件、录像控件、多镜录像控件等。其中，拍照控件处于选中状态，用于提示用户当前的取景界面用于执行拍摄功能。
在显示界面204期间，手机可以接收用户对人像控件、录像控件、多镜录像控件中任一控件的操作，并基于该操作确定切换后的功能模式，并显示执行该功能模式前的取景界面。例如，在手机接收到用户对人像控件的操作，如，点击操作时，可以显示执行人像拍摄功能前的取景界面。与此同时，人像控件处于被选中的状态。在手机接收到用户对录像控件的操作，如，点击操作时，可以显示执行录像功能前的取景界面。与此同时，录像控件处于被选中的状态。另外，如图2中的(b)所示，在手机接收到用户对多镜录像控件的操作，如，点击操作时，可以显示执行多镜录像功能前的取景界面，也即，如图2中的(c)所示的界面205，与此同时，多镜录像控件处于被选中的状态。可以理解的，上述界面205是第四界面的一个示例，在另一些实施例中，执行常规的录像功能前的取景界面也可以称为第四界面。
其中，录像功能和多镜录像功能都可以录制视频数据，二者的区别在于：录制开始时，所启用的镜头模式不同。在录像功能下，手机可以响应于用户的操作，启用单前模式或单后模式等单摄镜头模式进行视频的拍摄。而在多镜录像功能下，手机可以响应于用户的操作，启用前后模式、后后模式或画中画等多摄镜头模式进行视频的拍摄。本申请实施例所提供的方法不仅适用于录像功能下拍摄的视频数据，也适用于多镜录像功能下拍摄的视频数据，且实现原理相同。后续实施例中，主要以采用多镜录像功能为例，介绍本申请实施例所提供的方法。
执行多镜录像功能前，如图2中的(c)所示，手机所显示的取景界面(也即，界面205)中包括多个取景框，如，取景框206和取景框207。其中，取景框206和取景 框207的排布位置关系与手机的姿态相关。例如，在手机的陀螺仪传感器识别出手机处于竖屏状态的场景下，上述取景框206和取景框207上下排布。在手机的陀螺仪传感器识别出手机处于横屏状态的场景下，上述取景框206和取景框207左右排布。
另外，取景框206和取景框207分别对应有摄像头。例如，取景框206对应摄像头1(如，后置摄像头a)，这样，取景框206可以用于显示摄像头1上传的视频流。取景框207对应摄像头2(如，前置摄像头)，这样，取景框207可以用于显示摄像头2上传的视频流。可以理解地，各取景框(如，取景框206和取景框207)所对应的摄像头，可以依据用户的操作进行调整。各取景框所对应的摄像头变化后，意味着手机所使用的镜头模式也随之改变，后续实施例中会介绍镜头模式切换的几种场景，在此不赘述。
另外，在界面205中，手机可接收用户的操作2，该操作2用于触发手机在不选择任何特效的情况下直接开始视频拍摄。该操作2又可称为第三操作。示例性的，界面205中包括用于指示启动拍摄的控件208，也即，第一控件。手机接收到用户对控件208的第三操作，如，点击操作时，可以显示正在录制视频的取景界面，如称为第五界面，例如，图2中的(d)所示的界面209。其中，界面209是第一镜头模式下的录制取景界面，如，是前后模式所对应的录制取景界面。
界面209也包括取景框206和取景框207。这样，手机的界面209可以显示前置摄像头和后置摄像头a实时采集到的视频流。与此同时，手机还可以将前置摄像头和后置摄像头a采集的视频流进行渲染合并，之后编码，生成视频数据，并保存。在拍摄过程中，视频数据的视频帧会逐渐增加。
另外，在视频拍摄过程中，手机可以在界面209中接收用户的操作3，上述操作3可以是指示切换镜头模式的操作。手机可以响应于该操作3，启用不同的摄像头或不同的摄像头组合进行视频流的采集，以便于用户创造出布景多样、内容丰富的视频。
示例性地，界面209中可以包括用于指示切换镜头模式的控件，又称为第二控件，如，图3中的(a)所示的控件301。其中，控件301的图标用于指示当前启用的镜头模式。在手机接收到用户对控件301的操作之后，如图3中的(b)所示，可以在界面209中显示镜头模式选择窗，如，窗口302。其中，该窗口302中罗列有多个可供选择的镜头模式，如，前后模式、后后模式、画中画模式、单后模式、单后模式等。在窗口302中，前后模式处于选中状态。在此场景下，手机可以接收用户对后后模式、画中画模式、单后模式或单后模式的选择操作，并响应于该选择操作，切换所使用的镜头模式。上述实现切换镜头模式的操作，可称为第四操作。
例如，手机接收到用户对画中画模式的选择操作时，手机可以将镜头模式切换为画中画模式。也就是，如图3中的(c)，手机可以切换显示界面303。其中，界面303是第六界面的一个示例。可以理解的，第六界面是指切换镜头模式(又称为第二镜头模式)之后，对应的视频录制界面。该界面303中也包括取景框206和取景框207。其中，取景框206继续用于显示后置摄像头a上传的视频流，而取景框207也将继续用于显示前置摄像头上传的视频流。
另外，在切换过程中，取景框207缩小。而，取景框206增大。另外，取景框207叠于取景框206之上。在此过程，前置摄像头和后置摄像头a的相机参数也会调整。 在调整相机参数之后，前置摄像头和后置摄像头a采集到的视频流可能出现上传不及时的问题。这将致使拍摄到的视频数据1中出现停顿片段。也就是，如图3中的(c)所示，界面303的取景框206和取景框207会出现短暂的黑屏。当然，在相机参数配置完成后，如图3中的(d)所示，界面303的取景框207实时显示前置摄像头上传的视频流，取景框206实时显示后置摄像头a上传的视频流。
参考图4，图4概念性地展示了手机拍摄视频的过程中，镜头模式切换(从前后模式切换为画中画模式)后，对视频数据1的影响。在视频数据1的相对时间轴上，在时刻00:00到00:05之间，前置摄像头和后置摄像头a均可以正常上传视频流，同时，手机也可以依据前置摄像头和后置摄像头a上传的视频流正常地进行编码，生成连续的多帧视频帧，又称为视频片段1。其中，相对时间轴是基于视频数据1创建的时间轴。该相对时间轴的时刻00：00对应于视频数据1的第一帧视频帧(又称为首帧)的采集时间。
在时刻00:05之后，手机检测到指示切换至画中画模式的操作，该时刻00:05是第一时间点的一个示例。该操作可以短暂地影响到前置摄像头和后置摄像头a的视频流回传，故，在时刻00:05至时刻00:06之间出现缺视频帧的问题。而时刻00:06之后，前置摄像头和后置摄像头a又恢复正常，又可以采集并编码得到连续的视频帧，又可称为视频片段2。
在本申请实施例中，如图5所示，手机可以在时刻00:05至时刻00:06之间，插入多帧替代帧1，以使得到视频数据1连贯流程。在时刻00:05(也即，第一时间点)之后插入的替代帧1，又可称为第一时间点所对应的视频帧。
在一些示例中，在手机确定用户指示切换到画中画模式之后，手机可以将视频帧401(视频片段1中的最后一帧)定格，得到替代帧1。在此场景下，替代帧1所显示的画面内容与视频帧401相同。在重新接收到各摄像头回传的视频流之后，手机取消针对视频帧401的帧定格。
在另一些示例中，在确定用户指示切换到画中画模式之后，手机可以在视频帧401之后插入预习配置的图像帧，比如，黑色的图像帧或者白色的图像帧，直至重新接收到各摄像头回传的视频流之后，停止插入替代帧1。可理解地，所插入的图像帧也可以统称为替代帧1。
在其他示例中，在确定用户指示切换到画中画模式之后，手机可以对视频帧401进行标记。这样，在完成视频数据1的拍摄后，手机再自动于视频帧401之后插入多帧替代帧1。其中，该替代帧1可以是与视频帧401相同的图像帧，也可以是预先配置的白色图像帧或黑色图像帧。
再例如，在界面209中包括窗口302的情况下，如图6中的(a)所示，手机可以接收到用户对后后模式的选择操作。这样，手机可以响应于该选择操作，将使用的镜头模式切换为后后模式。也就是，如图6中的(b)，手机可以切换显示界面601。该界面601中也包括取景框206和取景框207。其中，取景框206用于显示后置摄像头a所上传的视频流，取景框207用于显示后置摄像头b所上传的视频流。
另外，除了在窗口302中选择后后模式之后，在显示界面209期间，也即，手机采用前后模式拍摄视频期间，手机接收到用户对控件602的操作，如点击操作时，也 可以将镜头模式切换为后后模式。
在切换为后后模式的过程中，取景框206和取景框207之间的相对位置和尺寸不变，手机启用后置摄像头b，并关闭前置摄像头，将后置摄像头b与取景框207对应上。这样，手机的取景框206继续显示后置摄像头a上传的视频流，而取景框207则显示后置摄像头b所上传的视频流。
在此过程，后置摄像头a回传视频流不受影响，如图6中的(b)所示，镜头切换期间取景框206的画面显示不受影响。但是，由于硬件反应延迟，前置摄像头关闭到后置摄像头b正常上传视频流之间存在时间间隙。在该时间间隙中，取景框207的画面显示会受影响，如图6中的(b)所示，取景框207出现短暂的黑屏。当然，在后置摄像头b可以正常上传视频流之后，如图6中的(c)所示，界面601的取景框207可以实时显示后置摄像头b上传的视频流，取景框206实时显示后置摄像头a上传的视频流。另外，该界面601也是第六界面的一个示例。
参考图7A，图7A概念性地展示了手机拍摄视频的过程中，出现镜头模式切换(从前后模式切换为后后模式)的情况下，生成视频数据1的示例图。
如图7A中的(a)所示，在视频数据1的相对时间轴上，在时刻00:05(第一时间点)至时刻00:06之间存在画面异常的多帧视频帧。这些画面异常的视频帧是由于镜头模式切换所导致的。
在一些实施例中，手机可以在指示启动后置摄像头b之后，对视频帧进行打点标记。在确定后置摄像头b已正常回传视频流之后，停止标记。这样，如图7A中的(b)所示，手机可以将标记位置所对应的视频帧剔除，这样，可以得到视频片段1和视频片段2。然后，为了确保视频数据的连贯性，如图7A中的(c)所示，手机还可以在视频片段1和视频片段2之间添加替代帧1，也即，也即第一时间点所对应的视频帧，从而，得到视频数据1。
在另一些实施例中，手机确定需启用新的摄像头(也即，后置摄像头b)之后，可以将已采集的最后一帧视频帧定格，如，将图7B中的视频帧701进行帧定格，得到替代帧1，也即第一时间点所对应的视频帧。在确定后置摄像头b已正常回传视频流之后，取消针对视频帧701的帧定格，依据后置摄像头a和后置摄像头b上传的视频流，正常编码，生成视频数据1。
可见，上述实施例中提到的添加替代帧1可以是在视频拍摄完成之后，也可以是在视频拍摄的过程中。
另外，切换镜头模式，不会中断视频的正常拍摄。例如，在手机切换为后后模式之后，手机可以显示界面601，并进行拍摄视频。这样，视频数据1所对应的视频帧数量将继续增加。
以上示例中，枚举了手机将镜头模式从前后模式切换为画中画模式，和从前后模式切换为后后模式。在实际应用中，其他镜头模式之间的切换，也存在类似的问题，也可以通过前述示例描述的，插入替代帧的方式进行解决，在此就不再赘述。
另外，在一些实施例中，手机还可以在界面601中接收用户指示停止拍摄的操作4。然后，手机可以响应于该操作4，停止视频的拍摄。
示例性地，如图8中的(a)所示，界面601中还包括用于指示暂停拍摄的控件， 又可称为第三控件，如，控件801。手机可以接收用户对控件801的第五操作，如，点击操作。并响应于针对控件801的点击操作，停止继续拍摄，并保存所拍摄的视频数据1。另外，如图8中的(b)所示，再次显示界面205。拍摄并保存视频数据1(也即，第一视频数据)之后，所显示的界面205又可称为第一界面。在此场景下，第一界面实际为相机应用提供的取景预览界面。
又示例性地，手机可以依据用户指示退出相机APP的操作，如，在界面601上的上滑操作，停止继续拍摄，并保存所拍摄的视频数据1。另外，手机还可以再次显示主界面。
在视频数据1保存之后，手机可以根据用户的操作4，显示所拍摄的视频数据1，方便用户查看或编辑视频数据1。
示例性地，在停止拍摄且手机显示界面205的场景下，该界面205中包括视频数据1的缩略图，如，图标802，又可称为第一缩略图。手机在显示界面205期间，可以接收用户对图标802的操作，并响应于该操作，显示视频编辑界面，如，图8中的(c)所示的界面803。该界面803用于显示视频数据1，又可称为第二界面。
又示例性地，在停止拍摄且手机显示界面205的场景下，手机可以依据用户指示退出相机APP的操作，如上划操作，再次显示手机的主界面，也即，桌面202。该桌面202中还包括图库APP的图标。这样，如图9中的(a)所示，在显示桌面202期间，手机可以接收针对图库APP的图标901的第六操作，如点选操作，并响应于该操作，显示图库APP所提供的应用界面，如图9的(b)所示的界面902。当然，在停止拍摄且手机显示主界面的场景下，手机可以直接接收针对图库APP的图标901的点选操作，并响应于该操作，显示图库APP所提供的应用界面，如图9的(b)所示的界面902。
在一些实施例中，界面902会显示各种图片资源和视频资源的缩略图，这些图片资源或者视频资源可以是手机拍摄并存储的，例如，视频数据1的缩略图903(又称为第一缩略图)，或者也可以是从网上下载的图像、视频等的缩略图，或者也可以是同步到云端的图像、视频等的缩略图。在一些示例中，用于显示视频资源缩略图的界面902，也可以称为第一界面。在此场景下，第一界面实际为所述图库应用提供的应用界面。
在一些实施例中，手机可接收用户对界面902中任一视频的缩略图的选择操作，响应于用户对任一视频的缩略图的选择操作，手机可显示对应的视频编辑界面。例如，手机响应于用户对界面902中缩略图903的第一操作，如点击操作，可显示图9中的(c)示出的界面803，界面803是视频数据1对应的视频编辑界面，也可称为第二界面。
在一些实施例中，手机可以依据用户在上述视频编辑界面的操作，播放对应的视频。示例性地，如图10所示，界面803中包括用于指示播放视频数据1的控件，如控件1001。在手机接收到用户针对控件1001的点击操作时，手机在界面803中播放视频数据1。
可以理解的，在视频数据1中添加有替代帧1的情况下，在播放过程中，会出现画面静止的情况。在本申请实施例中，手机在视频数据1中添加替代帧的同时，还可 以在多帧替代帧1上叠加转场特效，如称为转场特效1或者称为第一转场特效。实际叠加了第一转场特效的替代帧1又可称为第一视频帧。
在一些示例中，转场特效1可以手机中预先指定的任意一类转场特效，如，左移转场、右移转场、旋转转场、叠化转场、模糊转场、融化转场、黑场转场、白场转场、放大转场、缩小转场、上移转场和下移转场等中的一种。另外，需要说明书，上述转场特效之中，左移转场、右移转场只适用于竖屏拍摄视频的场景，而上移转场和下移转场只适用于横屏拍摄视频的场景。在另一些示例中，上转场特效1可以手机从上述多类转场特效中随机确定出的转场。
这样，播放视频数据1的过程中，转场特效1可以更好地衔接替代帧1前后的视频片段，也即，视频片段1和视频片段2之间可以更好的过度，提高用户的观赏体验，也增提高视频的拍摄质量。
另外，在添加转场特效1的区域，手机还可以对实际叠加转场特效的替代帧1进行标记，以便于手机可以识别出添加转场的位置。
在另一些实施例中，手机可以依据用户在上述视频编辑界面的操作，自动对视频数据1进行二次创作，比如，配置视频音乐、添加转场特效等。示例性地，如图11所示，界面803中还包括用于指示编辑视频数据1的控件，如，一键大片控件1101。在手机接收到用户对一键大片控件1101的操作，如称为第二操作，手机可以自动编辑视频数据1。
在一些实施例中，如图12所示，手机可以自动编辑视频数据1，可以包括以下步骤：
S101，手机确定与视频数据1匹配的效果模板。
在一些实施例中，手机内预先可以配置多类风格的效果模板，每一个效果模板都对应有一首视频音乐。此外，效果模板还对应有滤镜、特效、转场、贴纸。
在一些实施例中，手机可以利用人工智能模型，分析视频数据1的画面内容，确定与视频数据1匹配的效果模板，也即，第一效果模板，又称为效果模板1。例如，手机的人工智能模型依据视频数据1的画面内容，查找相似视频。并获取相似视频所用的视频音乐。这样，再依据获取的视频音乐，确定出对应的效果模板1。再例如，手机的人工智能模型依据视频数据1的画面内容，查找相似视频。依据相似视频的风格名称，确定属于相同风格的多个效果模板。然后，从确定出的多个效果模板中，随机确定效果模板1。在另一些实施例中，手机也可以随机确定出一效果模板，作为效果模板1。
S102，手机依据效果模板1，处理视频数据1。
示例性地，手机可以将视频数据1的原始音轨的音量调整至零，再将拍摄模板1的视频音乐添(也即，第一音乐)加到视频数据1，使视频音乐与视频数据1的视频画面契合。在其他实施例中，还可以按照用户的操作，将原始音轨音量调整至其他分贝值。
又示例性地，手机可以将效果模板1所对应的滤镜、特效、转场、贴纸添加到视频数据1中。其中，在添加转场特效的过程中，手机不仅可以在视频数据1中新增转场特效，还可以替换视频数据1中原有的转场特效(如，叠加在替代帧1上的转场特 效1)。
可以理解得，效果模板与各类转场特效之间的适配度不同。通常适配度越高的转场特效，相对而言，越适合该效果模板的风格和所对应的视频音乐。适配度越低的转场特效，相对而言，越不适合该效果模板的风格和所对应的视频音乐。在本实施例中，通过替换转场特效1的方式，改善利用效果模版处理视频数据之后，原有的转场特效1与处理后的视频风格冲突的问题。
在一些实施例中，如图13所示，手机可以先识别视频数据1中是否存在转场特效1。例如，可以通过检测视频数据1中是否存在标记。在识别出标记的情况下，将被标记的视频帧(也就是，叠加了转场特效1的替代帧1)删除，这样，视频数据1被分为视频片段1和视频片段2。然后，手机生成多张替代帧2和多张替代帧3。其中，替代帧2可以与视频片段1的尾帧相同，而替代帧3与视频片段2的首帧相同。上述视频片段1的尾帧和视频片段2的首帧可以统称为第二视频帧。
在一些示例中，替代帧2可以是手机对视频片段1的尾帧进行定格处理后，得到的图像帧。上述替代帧2可以是手机对视频片段2的首帧进行定格处理后，得到的图像帧。另外，替代帧2和替代帧3的总数量与删除的视频帧的数量相同，确保不影响最终视频数据1的长度。然后，手机依据效果模板1与各类转场特效之间的适配度，确定出转场特效2，并将转场特效2叠加到替代帧2和替代帧3之间，实现衔接视频片段1和视频片段2。
在一些实施例中，效果模板与转场特效之间的适配度可以量化为匹配权重。这样，在确定转场特效2时，手机可以结合效果模板1与各转场特效之间匹配权重，从多类转场特效中，随机选出与效果模板1匹配的转场特效2。可理解地，匹配权重越高的转场特效，相对而言，更容易被选为与效果模板1匹配的转场特效2。匹配权重越低的转场特效，相对而言，更难被选为与效果模板1匹配的转场特效2。
在一些示例中，效果模板与转场特效的匹配权重可以预先配置。示例性地，如下表1所示：
表1
Figure PCTCN2022094793-appb-000001
Figure PCTCN2022094793-appb-000002
上述表1例举了，不同效果模板与视频音乐、风格、不同转场特效的匹配权重之间的对应关系。其中，表格中各转场特效所对应的百分比值，为该转场特效与效果模板之间的匹配权重。效果模板1所对应的风格又称为第一风格。
以表1中记录的你好夏天效果模板为例。该效果模板与叠化转场之间的匹配权重为50％，也即，叠化转场有50％的概率被选为匹配的转场特效。另外，该效果模板与模糊转场之间的匹配权重为0％，也即，模糊转场也不会被选为匹配的转场特效。该效果模板与融化转场之间的匹配权重为0％，也即，融化转场也不会被选为匹配的转场特效。该效果模板与上移转场之间的匹配权重为50％，也即，手机需处理的横屏视频数据1的场景下，上移转场有50％的概率被选为匹配的转场特效。该效果模板与下移转场之间的匹配权重为50％，当然，手机需处理的横屏视频数据1的场景下，下移转场有50％的概率被选为匹配的转场特效。该效果模板与左移转场之间的匹配权重为50％，也即，手机需处理的竖屏视频数据1的场景下，左移转场有50％的概率被选为匹配的转场特效。该效果模板与右移转场之间的匹配权重为50％，当然，手机需处理的竖屏视频数据1的场景下，右移转场有50％的概率被选为匹配的转场特效。该效果模板与黑场转场之间的匹配权重为90％，也即，黑场转场有90％的概率被选为匹配的转场特效。该效果模板与白场转场之间的匹配权重为90％，也即，白场转场有90％的概率被选为匹配的转场特效。该效果模板与放大转场之间的匹配权重为90％，也即，放大转场有90％的概率被选为匹配的转场特效。该效果模板与缩小转场之间的匹配权重为90％，也即，缩小转场有90％的概率被选为匹配的转场特效。该效果模板与旋转转场之间的匹配权重为30％，也即，旋转转场有30％的概率被选为匹配的转场特效。
也就是，手机可以利用各转场特效所对应的匹配权重，随机选出替换转场特效1的转场特效2。这种选择方式不仅灵活性高，又可以保障选出的转场特效2与效果模板1之间大概率存在高关联。另外，手机在视频数据1中新增转场特效场景下，也可以利用各转场特效所对应的匹配权重，随机确定出与效果模板1匹配的转场特效3(又称为第三转场特效)，并将转场特效3添加于视频数据1中，如，添加于视频数据1 中第二时间点所对应的视频帧上。其中，第二时间点所对应的视频帧可以是：在视频数据1中，位于第二时间点前后的视频帧。如此，处理得到的视频数据1可呈现的风格可以更加接近效果模型的预期效果。
在另一些实施例中，效果模板1还可以与一个或多个转场特效之间存在关联标识，利用效果模板1处理视频数据1时，可以优先选用存在关联标识的转场特效，以作为转场特效2。
在另一些实施例中，在利用匹配的效果模板1处理视频数据1之后，手机还可以依据用户的操作，更换处理视频数据1时所用的效果模板，或单独更改所用的视频音乐。
示例性地，如图14中的(a)所示，在手机利用效果模板处理视频数据1之后，手机可以显示预览界面，如界面1401，如称为第三界面。该第三界面用于显示视频数据2，又称为第二视频数据，其中，视频数据2是在视频数据1的基础上，经过效果模板处理后得到的视频。该第二视频数据中包括视频数据1中的视频帧、替代帧(如，替代帧2和替代帧3)、效果模板1对应的视频音乐(如，称为第一音乐)和转场特效2(又称为第二转场特效)。手机可以接收用户在界面1401上的操作6，如，点击界面1401上的风格控件1402的操作。并响应该操作6，如图14中的(b)所示，显示界面1403。其中，界面1403是指引用户选择效果模板的引导界面。上述界面1403中包括多个指示不同效果模板的模板窗口。例如，窗口1404、窗口1405、窗口1406和窗口1407。其中，上述窗口1404用于指示命名为你好夏天的效果模板，窗口1405用于指示命名为sunny的效果模板，窗口1406用于指示命名为HAPPY的效果模板，窗口1407用于指示命名为小美好的效果模板。在这些效果模板中，你好夏天效果模板的模板窗口处于选中状态，指示效果模板1为你好夏天效果模板。这样，手机可以依据用户对其他模板窗口的操作，确定出用户选择的效果模板2。例如，手机接收到用户对窗口1405的点击操作后，界面1403中的预览窗口1408可以显示sunny效果模板的样片。这样，手机如果接收到用户对界面1403中的控件1409的操作，可以确定将sunny效果模板是选出的效果模板2。之后，手机可以利用效果模板2处理原始的视频数据1，得到符合效果模板2风格的视频数据1，并如图14中的(c)所示，再次显示界面1401，此时的界面1401中包括基于效果模板2处理后的视频数据1。
另外，在显示界面1403期间，手机并未接收到用户指示选择其他效果模板的操作的情况下，接收到用户对控件1409的操作。手机可以确定用户指示利用效果模板1重新处理原始的视频数据1。在重新处理的过程中，依然可以利用各转场特效与效果模板1之间的匹配权重，重新随机确定转场特效2和转场特效3，并用于重新处理原始的视频数据1。可以理解的，重新随机出的转场特效2和转场特效3，可能与第一次利用效果模板1确定出的转场特效不同。这样，再次处理后得到的视频数据1的视觉效果也会不同，提升一键成片的多样性。
又示例性地，手机可以接收用户在界面1401上的操作7，如，点击界面1401上的音乐控件1410的操作。并响应该操作7，更换不同的视频音乐。所更换的视频音乐可以是与效果模板2对应相同风格的音乐，也可以随机的一首音乐，对此不作限定。
另外，在界面1401中还包括指示确定的控件1411。如图14中的(c)所示，手 机接收到用户对控件1411的操作，如点击操作之后，保存处理后的视频数据1，如，将基于效果模板处理后的视频数据1又称为视频数据2。此外，手机还可以显示视频数据2所对应的视频编辑界面，如图14中的(d)所示的界面1412。该界面1412可以显示视频数据2。手机可以依据用户在界面1412中的操作，播放视频数据2。
在可能的实施例中，界面1401中还可以包括指示撤销效果模板的控件，如，图14中的(a)所示的控件1413。手机可接收用户针对控件1413的点击操作，删除基于效果模板处理后的视频数据1，并再次显示界面803。在手机再次显示界面803的情况下，交界803中依然包括一键大片控件1101。若手机再次接收到用户对一键大片1101的操作时，则可以再次确定一匹配的效果模板，利用新确定出的效果模板再次处理视频数据1，处理过程可参考前述实施例，在此不再赘述。另外，针对同一段视频数据1，手机可以使相邻两次通过一键大片确定的效果模板不同，提升二次创作视频数据的多样性。
本申请实施例还提供一种电子设备，该电子设备可以包括：存储器和一个或多个处理器。该存储器和处理器耦合。该存储器用于存储计算机程序代码，该计算机程序代码包括计算机指令。当处理器执行计算机指令时，可使得电子设备执行上述实施例中手机执行的各个步骤。当然，该电子设备包括但不限于上述存储器和一个或多个处理器。例如，该电子设备的结构可以参考图1所示的手机的结构。
