本申请要求在2017年08月31日提交中国专利局、申请号为201710772780.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及但不限于多媒体技术，例如涉及一种视频剪辑的方法及终端。
背景技术
目前，用户通过移动终端(包括手机、平板、以及视频播放器等终端)进行视频剪辑时，往往只选择视频的头部和/或尾部进行简单的剪辑(包括：剪除视频的头部、剪除视频的尾部、或对视频的部分头部和部分尾部均进行剪除处理)。
仅选择视频的头部和/或尾部进行剪辑，对于需要对视频进行复杂剪辑(对视频文件中多个片段进行剪切并对拼接)的用户而言，用户体验较差。
发明内容
本申请实施例提供一种视频剪辑的方法及终端，能够在移动终端上实现多个视频片段的剪切，提升用户体验。
本申请实施例提供了一种视频剪辑的方法，包括：分别确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间；根据确定的至少两个待剪辑视频片段的起始时间和终止时间对所述视频文件进行剪切。
本申请实施例还提供一种终端，包括：时间确定单元和剪切单元；其中，时间确定单元设置为：确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间；剪切单元设置为：根据确定的至少两个待剪辑视频片段的起始时间和终止时间对所述视频文件进行剪切。
本申请实施例还提供一种计算机存储介质，计算机存储介质中存储有计算机可执行指令，计算机可执行指令设置为执行上述视频剪辑的方法。
本申请实施例还提供一种终端，包括：存储器和处理器；其中，处理器被配置为执行存储器中的程序指令；程序指令在被处理器读取并执行时实现以下操作：分别确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间； 根据确定的至少两个待剪辑视频片段的起始时间和终止时间对所述视频文件进行剪切。
附图概述

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1为本申请实施例视频剪辑的方法的流程图，如图1所示，包括：步骤100和步骤101。
在步骤100中，分别确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间。在一实施例中，本申请实施例确定至少两个待剪辑的视频片段的起始时间和终止时间可以通过预设的交互界面，交互界面可以参照相关技术已有的实现方式进行设计。
在一实施例中，本申请实施例在步骤100之前还包括：获取视频文件包含的多个视频帧的时间点信息；按照预设单位时长以及所述多个视频帧的时间点信息，将所述视频文件划分为多个单位视频片段，以根据划分的多个单位视频片段确定至少两个待剪辑视频片段的起始时间和终止时间；其中，所述时间点信息包括：所述多个视频帧的起始时刻和终止时刻。
在一实施例中，本申请实施例确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间包括：在预设的第一用户交互界面上通过预设的交互单元显示所述多个单位视频片段；通过所述预设的交互单元确定每一个待剪辑视频片段的起始位置所在的单位视频片段，将所述每一个待剪辑视频片段的起始位置所在的单位视频片段的起始时刻作为所述起始时间；通过所述预设的交互单元确定每一个待剪辑视频片段的终止位置所在的单位视频片段，将所述每一个待剪辑视频片段的终止位置所在的单位视频片段的终止时刻作为所述终止时间。
图2为本申请实施例第一用户交互界面的示意图，如图2所示，在交互单元上显示划分的单位视频片段，显示的单位视频片段可以按照时间顺序排列，通过点击在显示单元上显示的单位视频片段，可以对单位视频片段进行选择；当需要确定待剪辑视频片段的起始位置时，点击待剪辑视频片段的起始位置所在的单位视频片段，在第一用户交互界面上可以显示点击的单位视频片段(如图2所示显示的单位视频片段m)，确定待剪辑视频片段的起始位置；当需要确定待剪辑视频片段的终止位置时，点击待剪辑视频片段的终止位置所在的单位视频片段，在第一用户交互界面上可以显示点击的单位视频片段(如图2所示显示的单位视频片段n)，确定待剪辑视频片段的终止位置。本申请实施例还可以对单位视频片段进行编号或采用区分标识进行区分，以便于点击选择单位视频片段时更为主观和准确。另外，本申请实施例可以在完成视频文件的剪辑之后，对剪辑获得的视频文件确定更小单位视频片段；通过确定的更小的单位视频片段对起始时间和终止时间不够准确的视频文件重新进行剪辑；当然，该过程还可以在第一次确定视频片段的起始时间和终止时间之后，直接确定的待剪辑的视频片段中定义更小的单位视频片段，并通过与上述交互单元相同的方式确定更为准确的起始时间和终止时间。
在一实施例中，本申请实施例确定至少两个待剪辑的视频片段起始时间和终止时间包括：
通过预设的第二用户交互界面接收所述至少两个待剪辑视频片段的起始时间和终止时间。
这里，第二用户交互界面可以是包含添加起始时间和终止时间的文本输入框界面，包含多个待剪辑的视频片段时，可以多次输入相应的起始时间和终止时间。
图3为本申请实施例第二用户交互界面的示意图，如图3所示，在第二用 户交互界面上包含添加起始时间和终止时间的文本输入框，起始时间和终止时间可以通过分号分开；通过一组包含添加起始时间和终止时间的文本输入框可以实现对一个带剪辑的视频片段的确认。
在步骤101中，根据确定的至少两个待剪辑视频片段的起始时间和终止时间对所述视频文件进行剪切。
在一实施例中，对视频片段进行剪切和拼接可以采用相关技术中已有的方法实现，在此不做赘述。
在一实施例中，本申请实施例对视频文件进行剪切之后，还包括：对剪切获得的所述至少两个待剪辑视频片段，根据时间先后顺序进行拼接，以获得剪辑的视频文件。
在一实施例中，剪切待剪辑的视频片段之前，本申请实施例方法还包括：对多个单位视频片段按照预设规则进行排序，并结合预设单位时长的时间长度，确定每个单位视频片段的起始时刻和终止时刻；根据确定的所述每个单位视频片段的起始时刻和终止时刻，及多个视频帧的起始时刻和终止时刻，确定所述每个单位视频片段包含的视频帧，以在确定至少两个待剪辑视频片段的起始时间和终止时间后对所述视频文件进行剪切。
与相关技术相比，本申请实施例提供了一种视频剪辑的方法，通过确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间；根据确定的各待剪辑视频片段的起始时间和终止时间对所述视频文件进行剪切。本申请实施例实现了在移动终端上进行多个视频片段的剪切，提升了用户体验。
图4为本申请实施例终端的结构框图，如图4所示，包括：时间确定单元和剪切单元。
时间确定单元设置为：分别确定视频文件中至少两个待剪辑视频片段的起始时间和终止时间。

以下通过应用示例对本申请实施例进行清楚详细的说明，应用示例仅用于陈述本申请，并不用于限定本申请的保护范围。
应用示例
图5为本申请应用示例的方法流程图，如图5所示，包括：步骤500至步骤508。
在步骤500中，获取视频文件的总时长。
本应用示例假设视频文件的总时长为1分钟。
在步骤501中，将视频文件划分为两个或两个以上单位视频片段。
即根据视频文件，将视频文件等分为两个或两个以上单位视频片段，每个单位视频片段的时长为总时长处于划分的单位视频片段的个数；假设将总时长的视频文件平分为60等份，那么每个等份的时长为1000毫秒。
在步骤502中，对划分的两个或两个以上单位视频片段，按照时间先后顺序进行编号。
本应用示例对将总时长的视频文件平分为60等份的单位视频片段，把1-1000毫秒段编号为1，1001-2000毫秒段编号为2，依次类推，编号从1到60。
在步骤503中，确定每一个单位视频片段包含的多个视频帧的时间点信息。
其中，所述时间点信息包括：所述多个视频帧的起始时刻和终止时刻。
在步骤504中，确定每一个单位视频片段的起始时刻和终止时刻。
即确定每一个单位视频片段包含的视频帧。本应用示例确定每一个单位视频片段的第一个视频帧的起始时刻即可确定该单位视频片段的终止时刻，例如、分别确定1毫秒、1001毫秒、2001毫秒、3001毫秒…58001毫秒、以及59001毫秒的视频帧后，可以确定第一个单位视频片段的终止时刻为1001毫秒视频帧之前一个视频帧。
在步骤505中，在第一用户交互界面上依次列出划分的单位视频片段。
图6为本申请应用示例显示划分的单位视频片段的示意图，如图6所示，在交互单元上显示了编号为1～60的单位视频片段。
在步骤506中，接收用户的点击操作，确定多个待剪辑视频片段的起始单位视频片段和终止单位视频片段，作为待剪辑视频片段的起始位置和终止位置。
假设用户选择了编号3～6、17～18、40～42的待剪辑视频片段，则点击编号为3的单位视频片段时，编号为3的单位视频片段作为编号从3～6待剪辑视频 片段的起始位置，编号为6的单位视频片段作为编号从3～6待剪辑视频片段的终止位置；按照相同方式确定待剪辑视频片段17～18、待剪辑视频片段40～42的起始位置和终止位置。
在步骤507中，对确定的待剪辑视频片段进行剪切。
即对起始时刻为2001毫秒、终止时刻为6000毫秒的视频帧进行剪切、对起始时刻为16001毫秒、终止时刻为18000毫秒的视频帧进行剪切、对起始时刻为39001毫秒、以及终止时刻为42000毫秒的视频帧进行剪切。
在步骤508中，对剪切的待剪辑视频片段按照时间顺序进行排序后进行拼接，获得待剪辑的视频文件。
本应用示例通过相关技术中已有的视频容器进行待剪辑视频片段的拼接，生成待剪辑的视频文件。本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的每个模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本申请不限制于任何特定形式的硬件和软件的结合。
