本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的视频生成方法、装置、电子设备及介质进行详细地说明。
本申请实施例提供的视频生成方法可以应用于用户使用电子设备生成可以倒序播放的视频的场景。
针对用户使用电子设备生成可以倒序播放的视频的场景，假设用户使用电子设备在拍摄一段海上日出的视频，该视频中太阳从海平面缓缓升起，慢慢地照亮了整个天空，然而，在某些特殊的场景下，用户需要对视频进行倒序播放以增强视频播放的趣味性，例如，当太阳升起的过程中碰到了一片云朵，用户想要将视频中的太阳由从下至上升起改为自上而下降落，以增强该视频播放的趣味性。在现实情况下，用户只能等整个视频拍摄完成后，利用视频特效应用先找到想要进行倒序播放的视频片段，然后对该片段进行截取，并对截取的视频片段进行倒序处理，最后再插入到原视频中。但是，生成倒序视频的整个处理过程用户需要借助第三方应用，并且操作复杂，效率较低。
而在本申请实施例中，用户使用电子设备拍摄一段海上日出的视频过程中，当视频中太阳从海平面缓缓升起时碰到了一片云朵，若此时用户想要将视频中的太阳由从下至上升起改为自上而下降落，以增强该视频播放的趣味性，则用户只需要点击电子设备中的目标控件上的倒序开关，就可以对之后拍摄的一个视频片段进行倒序标记，当用户点击目标控件上的正序开关后，又可以对之后拍摄的一个视频片段进行正序标记，拍摄过程中用户可以随时对需要倒序处理的视频片段进行选择，最后视频拍摄完成后，电子设备对所有倒序标记的视频片段进行倒序处理，并和正序标记的视频片段进行拼接处理，直接生成包括正序播放和倒序播放的视频，而无需用户使用第三方应用对拍摄的视频进行复杂的后期处理，因此简化了用户使用电子设备生成满足需求的倒序视频的方式，提高了生成倒序视频的效率。
本申请实施例提供的视频生成方法的执行主体可以为视频生成装置。其中，视频生成装置可以为电子设备，或该电子设备中的功能模块。以下将以电子设备为例对本申请实施例提供的技术方案进行说明。

步骤101、电子设备在录制视频的过程中，接收用户的第一输入。
可选地，本申请实施例中，在用户想要使用电子设备对某个场景进行录制时，可以触发电子设备开启具有视频录制功能的应用，并对该应用的界面中的第一标识进行选择输入(例如点击输入)后对准要拍摄的场景，然后用户可以对该应用的界面中的第二标识进行选择输入(例如点击输入)，以使得电子设备可开始录制该场景的视频。
其中，上述第一标识用于选择触发电子设备进入正序录制模式还是倒序录制模式；上述第二标识用于选择触发电子设备开始录制视频。
需要说明的是，上述“正序录制模式”可以理解为：在该正序录制模式下录制的视频在录制结束后进行播放时，视频中的画面是按照时间先后的顺序进行正序播放的；上述“倒序录制模式”可以理解为：在该倒序录制模式下录制的视频在录制结束后进行播放时，视频中的画面是按照时间先后的顺序进行倒序播放的。
可选地，本申请实施例中，上述第一标识可以为组合互斥开关的图标，该组合互斥开关包括正序开关和倒序开关。其中，当用户选择倒序开关后，则正序开关自动置灰并关闭，倒序开关高亮并开启；当用户选择正序开关后，则倒序开关自动置灰并关闭，正序开关高亮并开启。
可选地，本申请实施例中，上述第二标识可以为快门开关的图标，当用户选择开启快门开关后，快门开关高亮，并且电子设备开始录制视频；当用户选择关闭快门开关后，快门开关置灰，并且电子设备停止录制视频。
可选地，本申请实施例中，上述第一输入用于切换电子设备的视频录制模式，可以用于将电子设备由正序录制模式切换为倒序录制模式，也可以用于将电子设备由倒序录制模式切换为正序录制模式。
可选地，本申请实施例中，上述第一输入包括但不限于：用户通过手指或者手写笔等触控装置对第一标识的触控输入，或者为用户输入的特定手势，或者为其他可行性输入，具体的可以根据实际使用需求确定，本发明实施例不作限定。本申请实施例中的特定手势可以为单击手势、滑动手势、拖动手势、压力识别手势、长按手势、面积变化手势、双按手势、双击手势中的任意一种；本申请实施例中的点击输入可以为单击输入、双击输入或任意次数的点击输入等，还可以为长按输入或短按输入。
例如，上述第一输入具体可以为：在录制视频的过程中，用户对组合互斥开关中的正序开关进行点击的输入。
例如，上述第一输入具体还可以为：在录制视频的过程中，用户对组合互斥开关中的倒序开关进行点击的输入。
在一种示例中，如图2所示，用户触发电子设备开启具有视频录制功能的应用后，对该应用的界面中的组合互斥开关1中的正序开关2进行点击后，对准要拍摄的场景，然后 点击该应用界面中的快门开关3，以触发电子设备在正序录制模式下开始录制该场景的视频。在录制视频的过程中，用户对组合互斥开关1中的倒序开关4进行点击后(即第一输入)，正序开关2自动置灰并关闭，倒序开关4开启，从而触发电子设备由当前的正序录制模式切换为倒序录制模式。
在另一种示例中，用户触发电子设备开启具有视频录制功能的应用后，对该应用的界面中的组合互斥开关中的倒序开关进行点击后，对准要拍摄的场景，然后点击该应用的界面中的快门开关，以触发电子设备在倒序录制模式下开始录制该场景的视频。在录制视频的过程中，用户对组合互斥开关中的正序开关进行点击后(即第一输入)，倒序开关自动置灰并关闭，正序开关高亮并开启，从而触发电子设备由当前的倒序录制模式切换为正序录制模式。
在再一种示例中，用户触发电子设备开启具有视频录制功能的应用后，对准要拍摄的场景，然后点击该应用的界面中的快门开关，以触发电子设备默认在倒序录制模式下开始录制该场景的视频。在录制视频的过程中，用户对组合互斥开关中的正序开关进行点击后(即第一输入)，倒序开关自动置灰并关闭，正序开关高亮并开启，从而触发电子设备由当前的倒序录制模式切换为正序录制模式。
步骤102、电子设备响应于第一输入，获取N个第一视频数据，并按照第一编码方向对N个第一视频数据进行视频编码，得到第一视频片段。
本申请实施例中，N为正整数。
可选地，本申请实施例中，上述N个第一视频数据可以为电子设备处于倒序录制模式下录制的视频中的N个图像帧对应的N个图像数据，也可以为电子设备处于正序录制模式下录制的视频中的N个图像帧对应的N个图像数据。
可以理解，在录制视频的过程中，若用户对第一标识进行选择输入之前(即用户切换电子设备的录制模式之前)，电子设备处于正序录制模式，当用户对第一标识进行选择输入后(即将电子设备由当前的正序录制模式切换为倒序录制模式)，则N个第一视频数据为电子设备处于倒序录制模式下录制的视频中的N个图像帧对应的N个图像数据；若用户对第一标识进行选择输入之前(即用户切换电子设备的录制模式之前)，电子设备处于倒序录制模式，当用户对第一标识进行选择输入后(即将电子设备由当前的倒序录制模式切换为正序录制模式)，则N个第一视频数据为电子设备处于正序录制模式下录制的视频中的N个图像帧对应的N个图像数据。
可选地，本申请实施例中，上述第一编码方向为对N个第一视频数据进行编码时的编码方向，当N个第一视频数据为电子设备处于倒序录制模式下录制的视频中的N个图像帧对应的N个图像数据，则第一编码方向为倒序编码；当N个第一视频数据为电子设备处于正序录制模式下录制的视频中的N个图像帧对应的N个图像数据，则第一编码方向为正序编码。
需要说明的是，电子设备的摄像模组在对某个场景进行视频录制的过程中，会产生视 频的原始数据，电子设备接收到录制视频的原始数据后，需对之进行数据编码后，才可保存为相应的视频格式，并进行视频文件的保存。也就是说，视频录制的过程也是对这些原始数据进行实时编码的过程。一般而言，目前主流的视频编码格式包括H.264、H.265、MPEG-4、MPEG-2、WMA-HD以及VC-1等，在视频录制的过程中，对录制视频的原始数据进行编码时，一般都是将一个时间段的视频图像看作是由P个图像帧进行拼接得来的。假设，视频拍摄时的帧率为30帧/每秒(Frames Per Second，FPS)，则一秒内电子设备接收到的图像数据就是30张图像帧的图像数据。如果该30张图像帧为正序录制模式下得到的图像帧，则对该30张图像帧的图像数据进行视频编码时的编码方向为：第1帧、第2帧、第3帧……直至第30帧；如果该30张图像帧为倒序录制模式下得到的图像帧，则对该30张图像帧的图像数据进行视频编码时的编码方向为：第30帧、第29帧、第28帧……直至第1帧。
可选地，本申请实施例中，电子设备对N个第一视频数据进行编码的方式可以为以下任意一项：变换编码、运动估计和运动补偿编码、熵编码等。
可选地，本申请实施例中，当N个第一视频数据为电子设备处于倒序录制模式下录制的视频中的N个图像帧对应的N个图像数据，则电子设备按照第一编码方向对该N个第一视频数据进行编码后，得到的第一视频片段在播放时的图像为倒序播放。
可选地，本申请实施例中，当N个第一视频数据为电子设备处于正序录制模式下录制的视频中的N个图像帧对应的N个图像数据，则电子设备按照第一编码方向对该N个第一视频数据进行编码后，得到的第一视频片段在播放时的图像为正序播放。
步骤103、电子设备根据第一视频片段和第二视频片段，生成目标视频。
本申请实施例中，上述第二视频片段包括：按照第二编码方向对M个第二视频数据进行视频编码得到的视频片段。
本申请实施例中，上述第一编码方向和第二编码方向不同，M为正整数。
可选地，本申请实施例中，上述M个第二视频数据为：在录制视频的过程中，获取的时间位于N个第一视频数据之前的视频数据。可选地，在本申请实施例的一种可能的实现方式中，在录制视频的过程中，当用户对第一标识进行选择输入后，即将电子设备的录制模式由正序录制模式(或倒序录制模式)切换为倒序录制模式(或正序录制模式)后，电子设备会结束前一段视频(即第二视频片段)的录制，并保存该第二视频片段。其中，该第二视频片段包括M个第二视频数据。进一步可选地，本申请实施例中，电子设备对第一视频片段中的N个第一视频数据按照第一编码方向进行编码，并对第二视频片段中的M个第二视频数据按照第二编码方向进行编码，然后对编码后的第一视频段和第二视频段进行拼接处理，生成目标视频。
可选地，在本申请实施例的另一种可能的实现方式中，在录制视频的过程中，用户可以在视频录制界面进行上滑输入，以使得电子设备可以在视频录制界面上显示“文件管理”窗口，然后用户可以对该“文件管理”窗口中的目标文件进行输入，以使得该目标文件中 的第二视频片段可以加入视频拼接列表，然后用户使用电子设备在正序录制模式(或倒序录制模式)下录制一段视频后，得到第一视频片段，对第一视频片段中的N个第一视频数据按照第一编码方向进行编码后与第二视频片段进行拼接处理，生成目标视频。
可以理解，生成的目标视频既包括可以正序播放的视频段又包括可以倒序播放的视频段。为了使电子设备更好地识别哪些视频数据需要进行正序编码，哪些视频数据需要进行倒序编码，可以在对N个第一视频数据进行视频编码之前，对N个第一视频数据添加标记，以下具体进行说明。
可选地，本申请实施例中，结合图1，如图3所示，在上述步骤102中的“按照第一编码方向对N个第一视频数据进行视频编码，得到第一视频片段”之前，本申请实施例提供的视频生成方法还可以包括下述的步骤201。
步骤201、电子设备对N个第一视频数据添加第一标记。
本申请实施例中，上述第一标记用于标示N个第一视频数据对应的编码方向为第一编码方向。
可选地，本申请实施例中，在录制视频的过程中，若用户对第一标识进行选择输入之前(即用户切换电子设备的录制模式之前)，电子设备处于正序录制模式(或倒序录制模式)，当用户对第一标识进行选择输入后，即将电子设备由当前的正序录制模式(或倒序录制模式)切换为倒序录制模式(或正序录制模式)后，电子设备会结束录制当前的一个第二视频片段并保存，然后新建一个第一文件，且对该第一文件添加第一标记。其中，第一文件为存储N个第一视频数据的视频文件，第一标记用于标示视频文件内的视频数据的编码方向为倒序编码方向(或正序编码方向)。
可选地，本申请实施例中，第一标记可以为一个指令信息，该指令信息用于指示电子设备对第一标记标示的视频文件中的视频数据按照第一编码方向进行编码。
需要说明的是，用户在将电子设备由当前的正序录制模式切换为倒序录制模式后不影响正序录制的过程，即切换录制模式后的录制画面仍然可以是正常的正序录制，只不过会对建新的视频文件写入一个指令信息。
可选地，本申请实施例中，若N个第一视频数据为电子设备切换为倒序录制模式后获取的视频数据，则在倒序录制模式下的视频录制过程中，电子设备可以对写入第一文件内的N个第一视频数据进行倒序编码，并在视频录制结束，待倒序编码完成后，导出的第一文件中的第一视频在任意播放器播放时，视频图像都是倒序播放。
具体地，电子设备可以先接收N个第一视频数据，并保存第N个第一视频数据，作为起始视频数据，再将第N-1个第一视频数据写入到第N个第一视频数据之后，然后将第N-2个第一视频数据写入到第N-1个第一视频数据之后，以此类推，直至第1个第一视频数据写入到第2个第一视频数据之后，进而对倒序排列后的N个第一视频数据进行编码，得到的倒序编码的N个第一视频数据。
下面结合具体例子对上述过程进行详细说明。以第一文件包括5(N＝5)个第一视频 数据为例，如图4所示，第一排的视频数据为输入的5个第一视频数据，假设第1个第一视频数据指示的图像是字母A，第2个第一视频数据指示的图像是字母A、B，第3个第一视频数据指示的图像是字母A、B、C，第4个第一视频数据指示的图像是字母A、B、C、D，第5个第一视频数据指示的图像是字母A、B、C、D、E。第二排的倒序编码数据表示的是相应的每个视频数据的倒序编码数据，即先保存第5个第一视频数据(即最后一个视频数据)，作为起始视频数据，再将第4个第一视频数据写入到第5个第一视频数据之后，然后将第3个第一视频数据写入到第4个第一视频数据之后，以此类推，直至第1个第一视频数据写入到第2个第一视频数据之后，进而对倒序排列后的5个第一视频数据进行编码，得到的倒序编码的5个第一视频数据即得到第一视频段的编码数据。视频播放设备对该编码数据进行解码播放时，其呈现出的动画效果就是“ABCDE-ABCD-ABC-AB-A”五个字母逐个减少显示的画面。
可选地，本申请实施例中，在录制视频的过程中，若用户对第一标识进行选择输入之前(即用户切换电子设备的录制模式之前)，电子设备处于倒序录制模式，当用户对第一标识进行选择输入后(即将电子设备由当前的倒序录制模式切换为正序录制模式)，电子设备会结束对第二视频片段的录制，并新建一个第一文件，且对该第一文件添加第一标记。其中，第一文件为用于存储N个第一视频数据的视频文件，第一标记用于标示对应的编码方向为正序编码方向。
需要说明的是，电子设备对视频数据进行正序编码的过程说明可以参考现有的编码技术，在此不予赘述。
如此可知，由于电子设备对N个第一视频数据进行视频编码之前，可以先对该N个第一视频数据添加第一标记，以标示该N个第一视频数据对应的编码方向为第一编码方向，从而使电子设备更好地识别视频数据的编码方向，提高了电子设备对视频数据进行编码的准确性。
可选地，本申请实施例中，结合图1，如图5所示，在上述步骤102之前，本申请实施例提供的视频生成方法还可以包括下述的步骤301。
步骤301、电子设备对M个第二视频数据添加第二标记。
本申请实施例中，上述第二标记用于标识M个第二视频数据对应的编码方向为第二编码方向。
可选地，本申请实施例中，在录制视频开始，若用户对第一标识进行选择输入后，电子设备处于正序录制模式(或倒序录制模式)，电子设备新建一个第二文件，然后对该第二文件添加第二标记，视频录制过程中的M个第二视频数据会存储到该第二文件内。其中，第二文件为用于存储M个第二视频数据的视频文件，第二标记用于标示视频文件内的视频数据的编码方向为正序编码方向(或倒序编码方向)。
如此可知，由于电子设备在获取N个第一视频数据之前，可以先获取M个第二视频数据，并对该M个第二视频数据添加第二标记，以标示该M个第二视频数据对应的编码 方向为第二编码方向，从而使电子设备更好地识别视频数据的编码方向，提高了电子设备对视频数据进行编码的准确性。
本申请实施例提供的视频生成方法，电子设备可以在录制视频的过程中，根据用户的第一输入获取N个第一视频数据，并按照第一编码方向对获取的N个第一视频数据进行视频编码，得到第一视频片段，N为正整数；然后根据第一视频片段和第二视频片段(第二视频片段包括：按照第二编码方向对M个第二视频数据进行视频编码得到的视频片段)，生成目标视频。其中，第一编码方向和第二编码方向不同，M为正整数。由于电子设备在录制视频的过程中就可以根据用户的第一输入获取N个第一视频数据，并按照第一编码方向对N个第一视频数据进行视频编码，得到第一视频片段，且按照第二编码方向对M个第二视频数据进行视频编码，得到第二视频片段，最后根据第一视频片段和第二视频片段，生成目标视频，又由于第一视频片段和第二视频片段的视频编码方向是相反的，因而拍摄结束后得到的目标视频直接就是包括播放效果相反的视频片段的视频，而无需用户使用视频特效应用对拍摄的视频进行复杂的后期处理，因此简化了用户使用电子设备生成满足需求的特效视频的过程，节约了时间。
以下具体说明电子设备获取N个第一视频数据的过程。
可选地，本申请实施例中，结合图1，如图6所示，在上述步骤102中的“获取N个第一视频数据”具体可以通过下述的步骤102a来实现。
步骤102a、电子设备将第一时间段内采集的视频数据，确定为N个第一视频数据。
本申请实施例中，上述第一时间段的起始时刻为：第一输入的输入时刻；上述第一时间段的结束时刻为：第一时间段的起始时刻起的第一预设时长之后的时刻。
可选地，本申请实施例中，上述第一预设时长可以为用户在目标模板中预先设置的一个时长，该目标模板可以为视频录制前，用户在电子设备中选择并调用的可以定时切换视频录制模式的时间模板。
进一步可选地，本申请实施例中，上述目标模板包括X个第一指令和Y个第二指令，该第一指令用于指示电子设备在一个预设时长内保持处于正序录制模式或者倒序录制模式，X为正整数；该第二指令用于指示电子设备在一个预设时长内保持处于倒序录制模式或者正序录制模式，Y为正整数。其中，X和Y可以相同，也可以不同；电子设备执行第一指令后的视频录制模式和执行第二指令后的视频录制模式相反。
需要说明的是，上述“视频录制模式”可以理解为：电子设备处于的视频录制模式为正序录制模式还是倒序录制模式。
可以理解，若电子设备执行第一指令后的视频录制模式为正序录制模式，则电子设备执行第二指令后的视频录制模式为倒序录制模式；若电子设备执行第一指令后的视频录制模式为倒序录制模式，则电子设备执行第二指令后的视频录制模式为正序录制模式。
在一种示例中，时间模板可以为：正序10S+倒序10S，即该时间模板包括1个第一指令和1个第二指令。其中，第一指令指示电子设备在视频开始录制的第一个10S内保持处 于正序录制模式，第二切换指令指示电子设备在视频开始录制的第二个10S内保持处于倒序录制模式。
在另一种示例中，时间模板可以为：倒序5S+正序10S+倒序10S，即该时间模板包括2个第一指令和1个第二指令。其中，第1个第一指令指示电子设备在视频开始录制的5S内保持处于倒序录制模式，第1个第二指令指示电子设备在视频开始录制的第6S至15S内保持处于正序录制模式，第2个第一指令指示电子设备在视频开始录制的第16S至25S内保持处于倒序录制模式。
可选地，本申请实施例中，上述第一输入的输入时刻可以为电子设备接收到第二指令的时刻。
可以理解，当该第二指令指示电子设备由倒序录制模式切换为正序录制模式时，则第一时间段的起始时刻为：电子设备处于正序录制模式的开始时刻，第一时间段的结束时刻为：电子设备处于正序录制模式的时间满足该第二指令对应的预设时长之后的时刻；当该第二指令指示电子设备由正序录制模式切换为倒序录制模式时，则第一时间段的起始时刻为：电子设备处于倒序录制模式的开始时刻，第一时间段的结束时刻为：电子设备处于倒序录制模式的时间高超过该第二指令对应的预设时长之后的时刻。
在一种示例中，假设时间模板为：倒序10S+正序10S+倒序10S，电子设备开始录制视频后处于倒序录制模式保持10S后，接收到第二切换指令指示电子设备由倒序录制模式切换为正序录制模式，则第一时间段的起始时刻为：电子设备开始录制视频后的第11S，第一时间段的结束时刻为：电子设备开始录制视频的第20S之后的时刻(即电子设备处于正序录制模式的时间超过10S之后的时刻)。可以理解，电子设备在第11S到第20S(即第一时间段)内，即处于正序录制模式的10S内采集的N个视频数据，确定为N个第一视频数据。
在另一种示例中，假设时间模板为：正序5S+倒序5S+正序5S，电子设备开始录制视频后处于正序录制模式保持5S后，接收到第二切换指令指示电子设备由正序录制模式切换为倒序录制模式，则第一时间段的起始时刻为：电子设备开始录制视频后的第6S，第一时间段的结束时刻为：电子设备开始录制视频的第10S之后的时刻(即电子设备处于倒序录制模式的时间超过5S之后的时刻)。可以理解，电子设备在第6S到第10S(即第一时间段)内，即处于倒序录制模式的5S内采集的N个视频数据，确定为N个第一视频数据。
需要说明的是，上述目标模板可以为电子设备预存的时间模板也可以为用户自定义的时间模板，时间模板中的正序录制模式和倒序录制模式的切换顺序以及各个录制模式下的预设时间可以任意设置，在此不作限定。
如此可知，由于用户在设置第一输入的输入时刻和第一预设时长之后，电子设备可以在第一输入的输入时刻开始到第一预设时长之内的时间段中采集视频数据，并将采集到的视频数据确定为N个第一视频数据，从而用户可以使用电子设备得到各种满足需求的视频内容。
当然，用户有时需要使用电子设备录制包括正序视频段和倒序视频段混合的视频，以下针对这种情况进行具体说明。
可选地，本申请实施例中，上述第二视频片段还包括：按照第二编码方向对Q个第三视频数据进行视频编码得到的视频片段，Q为正整数，结合图6，如图7所示，在上述步骤102a之后，本申请实施例提供的视频生成方法还可以包括下述的步骤401。
步骤401、电子设备将第二时间段内采集的视频数据，确定为Q个第三视频数据。
本申请实施例中，上述第二时间段的起始时刻为：第一时间段的结束时刻；上述第二时间段的结束时刻为：第二时间段的起始时刻起的第二预设时长之后的时刻。
可选地，本申请实施例中，上述第二时间段的起始时刻为：电子设备执行第二指令后处于正序录制模式(或倒序录制模式)起的第一预设时长之后的时刻。
可以理解，第二时间段的起始时刻为：电子设备执行完一个第二指令后再次接收到第一指令的时刻。
可选地，本申请实施例中，上述第二预设时长可以为电子设备再次接收到的第一指令中用户预先设置或者目标模板中预置的一个时长。
在一种示例中，假设时间模板为：倒序10S+正序10S+倒序10S，电子设备开始录制视频后根据第1个第一指令处于倒序录制模式保持10S后，根据第二指令又处于正序录制模式保持10S，然后电子设备又接收到第2个第一指令，指示电子设备由正序录制模式切换为倒序录制模式，则第二时间段的起始时刻为：电子设备开始录制视频的第21S(即接收到第2个第一指令的时刻)，第二时间段的结束时刻为：电子设备开始录制视频后的第30S之后(即电子设备处于倒序录制模式的时间超过10S之后的时刻)。可以理解，电子设备在第21S到第30S(即第二时间段)内，即处于倒序录制模式的10S内采集的Q个视频数据，确定为Q个第三视频数据。电子设备得到Q个第三视频数据后，按照倒序编码的方式对Q个第三视频数据进行视频编码得到一个第二视频片段。
在另一种示例中，假设时间模板为：正序5S+倒序10S+正序10S，电子设备开始录制视频后根据第1个第一指令处于正序录制模式保持5S后，根据第二指令又处于倒序录制模式保持10S，然后电子设备又接收到第2个第一指令，指示电子设备由倒序录制模式切换为正序录制模式，则第二时间段的起始时刻为：电子设备开始录制视频的第16S(即接收到第2个第一指令的时刻)，第二时间段的结束时刻为：电子设备开始录制视频后的第25S之后(即电子设备处于正序录制模式的时间超过10S之后的时刻)。可以理解，电子设备在第16S到第25S(即第二时间段)内，即处于正序录制模式的10S内采集的Q个视频数据，确定为Q个第三视频数据。电子设备得到Q个第三视频数据后，按照正序编码的方式对Q个第三视频数据进行视频编码得到一个第二视频片段。
本申请实施例中，电子设备根据目标模板中的X个第一指令和Y个第二指令，得到X个包含第二视频数据的视频文件和Y个包含第一视频数据的视频文件后，对所有的第一视频数据按照第一编码方向进行视频编码，得到Y个第一视频片段，对所有的第二视频数据 按照第二编码方向进行视频编码，得到X个第二视频片段，最后按照视频文件的获取时间，对Y个第一视频片段和X个第二视频片段进行排序和拼接处理，得到目标视频。
如此可知，由于电子设备在第一时间段内采集第一视频数据后，还可以在第一时间段之后的第二时间段内采集第三视频数据，并对采集的第三视频数据按照第二编码方向进行视频编码得到一个第二视频片段，从而用户可以使用电子设备得到需要的任意数量的第一视频片段和第二视频片段。
