如图1所示，本公开实施例提供的一种视频的编辑方法，包括如下步骤：
S110、通过对目标视频中的音频进行语音识别，确定所述目标视频的语音文本中的无效文本及所述无效文本的时间线位置，所述无效文本的时间线位置用于表示所述无效文本的语音音频在所述目标视频中的出现时间。
目标视频可以是指需要进行编辑的视频，如目标视频可以为用户上传的视频，也可以为用户在线拍摄的视频。在本实施例中，目标视频中包含音频，语音文本可以认为是与目标视频的音频对应的文本信息，其可以通过对目标视频的音频进行语音识别得到。示例性的，语音文本中包括无效文本，无效文本可以包括目标视频中停顿、重复、口水词等用户不需要的片段对应的文本；无效文本的时间线位置可以用于表示无效文本的语音音频在目标视频中的出现时间。
在一个实施例中，目标视频为连续视频，如目标视频可以为某连续且完整视频，也可以为某完整视频的某一片段。
在本实施例中，可以通过对目标视频中的音频进行语音识别，来确定目标视频的语音文本中的无效文本及无效文本的时间线位 置，以进行后续的编辑步骤。其中，本步骤不对语音识别的具体方式以及触发语音识别的时机进行限定，如可以在界面中触发某识别控件来触发对目标视频中音频的语音识别，从而能够自动识别出目标视频中无效文本及无效文本的时间线位置，识别控件的位置及样式不限，可以根据实际页面的情况进行设置。
在一个实施方式中，无效文本的识别条件为：默认静音时长大于预设时长(如120ms等)的片段是停顿片段；通过复用预设算法逻辑来识别无效词(如重复与语气词)，该预设算法可以配置于当前应用程序内，也可以配置于服务器中。
图2为本公开实施例提供的一种触发语音识别的示意图，如图2所示，在选中某视频(如目标视频)后，可以在点击右键的弹出窗口中触发控件1，即可触发对目标视频中音频的语音识别。还可以点击当前界面中的快捷控件2实现对目标视频中音频的语音识别。
S120、在所述目标视频的编辑界面上展示所述目标视频的编辑轨道片段，并基于所述无效文本的时间线位置，在所述编辑轨道片段上标识所述无效文本的时间线区间，所述无效文本的时间线区间为所述无效文本的语音音频在所述目标视频中出现的时间区间。
编辑界面可以用于对目标视频中的片段进行编辑。目标视频的编辑轨道片段可以理解为与目标视频对应的编辑轨道片段，如起点与目标视频的起点对应、终点与目标视频的终点对应的编辑轨道片段。示例性的，当目标视频为连续且完整视频时，该编辑轨道片段可以为该连续且完整视频的编辑轨道；当目标视频为某完整视频的一个片段时，该编辑轨道片段可以为该完整视频的编辑轨道中与目标视频对应的轨道片段。可选的，所述编辑轨道片段为所述目标视频的音频轨道片段，音频轨道片段可以是指与目标视频对应的音频轨道片段。无效文本的时间线区间可以认为是无效文本的语音音频在目标视频中出现的时间区间。
在一个实施例中，当对目标视频中的音频进行语音识别确定目标视频的无效文本及无效文本的时间线位置后，可以在目标视频的 编辑界面上对目标视频的编辑轨道片段进行展示，并基于无效文本的时间线位置，在编辑轨道片段上标识无效文本的时间线区间。其中，展示编辑轨道片段以及标识无效文本的时间线区间的方式不限，可以由相关人员预先根据编辑界面的实际情况进行设置，如可以采用预设标识在目标视频的编辑轨道片段上标识无效文本中无效文本的时间线区间，该预设标识具体可以根据进行设置，示例性的，该预设标识可以为矩形框，此时，可以采用矩形框在目标视频的编辑轨道片段上框选目标视频中无效文本的时间线区间；或者，无效文本的时间线区间在编辑轨道片段中可以标识为第一展示样式，而其他文本的时间线区间在编辑轨道片段中标识为第二展示样式，第一展示样式区别于第二展示样式，如第一展示样式和第二展示样式可以以不同颜色进行区分，也可以通过不同的线条进行区分等。
在一个实施方式中，可以默认在编辑轨道片段上标识识别得到的所有无效文本的时间线区间，以区分无效文本的时间线区间与其他文本的时间线区间；也可以默认在编辑轨道片段上标识设定个数的无效文本的时间线区间，设定个数可以由相关人员预先进行设置。用户可以根据需要对无效文本的时间线区间进行调整。
图3为本公开实施例提供的一种编辑界面的示意图，如图3所示，目标视频的编辑界面上可以展示有目标视频的编辑轨道片段3，并基于上步骤识别出的无效文本的时间线位置，在编辑轨道片段3上对无效文本的时间线区间进行标识，如图3中以黑色的矩形框对无效文本的时间线区间4进行了标识。
S130、响应于所述无效文本的调整操作，在所述目标视频的编辑轨道片段上对所述无效文本的时间线区间进行调整。
无效文本的调整操作可以是指用于触发调整无效文本的时间线区间的操作，本实施例中无效文本的调整操作的具体操作方式不限，如无效文本的调整操作可以为点击编辑界面中某一控件的操作或者作用于编辑轨道片段上的预设出发操作，也可以为在编辑界面中进行预设手势的操作，预设手势可为预先设定的手势，如预设手势可 为向右滑动的手势等。
本实施例不对调整操作的触发位置进行限定，如可以作用在无效文本的时间线区间，也可以作用在其他位置，只要能触发调整无效文本的时间线区间即可。
具体的，本实施例可以响应于无效文本的调整操作，在目标视频的编辑轨道片段上对无效文本的时间线区间进行调整，具体调整时间线区间的方式可以根据调整操作的不同而有所区别，如当无效文本的调整操作为触发某控件以使无效文本的状态由选中状态变为未选中状态时，可以在目标视频的编辑轨道片段上对无效文本的时间线区间的数量进行调整，如在编辑轨道片段上增加标识某文本的时间线区间，以将此文本调整为无效文本，或者，在编辑轨道片段上取消标识某文本的时间区间，以将此文本调整为非无效文本。
S140、响应于所述无效文本的视频片段删除操作，将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除。
无效文本的视频片段删除操作可以是指用于触发删除编辑轨道片段上无效文本对应的视频片段的操作，例如无效文本的视频片段删除操作可以为点击编辑界面中某删除控件的操作等。
本步骤可以响应于无效文本的视频片段删除操作，将编辑轨道片段上位于无效文本的时间线区间内的视频片段从目标视频中删除，具体删除的方式不作限定，如可以根据用户需要保留或去除编辑轨道片段上无效文本的时间线区间对应的痕迹。如图3所示，用户触发控件5即可以认为是视频片段删除操作，在用户触发控件5后，电子设备可以响应于无效文本的视频片段删除操作，将无效文本的时间线区间6对应的视频片段从目标视频中删除。
在一个实施例中，所述将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除，包括：
将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除，并以删除的所述视频片段为分割点， 将所述目标视频分割为多个独立的视频片段；或者
将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除，并将删除所述视频片段后的目标视频整合为一个视频。
在一个实施方式中，可以将编辑轨道片段上位于无效文本的时间线区间内的视频片段从目标视频中删除，并以删除的视频片段为分割点，将目标视频分割为多个独立的视频片段，在此基础上，能够便于用户根据需要对各独立的视频片段进行操作。
在一个实施方式中，可以将编辑轨道片段上位于无效文本的时间线区间内的视频片段从目标视频中删除，并将删除视频片段后的目标视频整合为一个视频。在此基础上，实现了删除目标视频中无效片段的操作，提高了目标视频的质量。无效片段即为无效文本的时间线区间对应的片段，换言之，编辑轨道片段上所标识的时间线区间在目标视频的语音文本中所对应的文本。
本公开实施例提供的一种视频的编辑方法，通过对目标视频中的音频进行语音识别，确定所述目标视频的语音文本中的无效文本及所述无效文本的时间线位置，所述无效文本的时间线位置用于表示所述无效文本的语音音频在所述目标视频中的出现时间；在所述目标视频的编辑界面上展示所述目标视频的编辑轨道片段，并基于所述无效文本的时间线位置，在所述编辑轨道片段上标识所述无效文本的时间线区间，所述无效文本的时间线区间为所述无效文本的语音音频在所述目标视频中出现的时间区间；响应于所述无效文本的调整操作，在所述目标视频的编辑轨道片段上对所述无效文本的时间线区间进行调整；响应于所述无效文本的视频片段删除操作，将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除。利用该方法，通过对目标视频中的音频进行语音识别，能够对目标视频中的无效文本以及无效文本的位置进行确定，进而通过在目标视频的编辑轨道片段上标识无效文本的时间线区间，能够响应于用户对无效文本的调整操作和视频片段删 除操作，对无效片段进行删除，从而完成对视频的剪辑，提升了视频剪辑的效率。
在一个实施例中，所述方法还包括：
在所述编辑界面的视频区域播放所述目标视频；
当所述目标视频播放至第二时间线区间的起点位置时，将所述目标视频的播放进度调整至第一时间节点，并从所述第一时间节点继续播放所述目标视频，其中，所述第二时间线区间为所述无效文本的时间线区间，所述第一时间节点为所述第二时间线区间的终点位置在所述目标视频中所对应的时间节点。
其中，视频区域可以认为是编辑界面中的某个区域，用于播放目标视频，视频区域的具体位置及大小可以由相关人员根据编辑界面的情况进行设置。第二时间线区间可以是任一无效文本的时间线区间，第一时间节点可以理解为第二时间线区间的终点位置在目标视频中所对应的时间节点。
在一个实施方式中，可以在编辑界面的视频区域播放目标视频，播放目标视频的时机不限，如在显示编辑界面时可以自动对目标视频进行播放；也可以在显示编辑界面后，当用户触发编辑界面中的某播放控件时，在编辑界面的视频区域播放目标视频；还可以在显示编辑界面的预设时长后，自动对目标视频进行播放等，本实施例对此不作限定。
当目标视频播放至第二时间线区间的起点位置时，本实施例可以自动将目标视频的播放进度调整至第一时间节点，并从第一时间节点继续播放目标视频。在此基础上，通过播放目标视频时自动跳过无效片段，能够使用户预先观看到编辑后的视频，以对目标视频进行更好地编辑。
在一个实施例中，在所述编辑界面的视频区域播放所述目标视频之后，还包括：
响应于对第五文本的触发操作，将所述目标视频的播放进度调整至第二时间节点，并从所述第二时间节点继续播放所述目标视频， 所述第五文本显示于所述编辑界面的文本区域内，所述第五文本为无效文本或非无效文本，所述第二时间节点为所述第五文本的起点位置在所述目标视频中所对应的时间节点。
在本实施例中，第五文本可以为用户所触发的文本，其可以为无效文本或非无效文本。非无效文本即为除无效文本之外的文本，如目标视频的语音文本中的有效文本。第五文本可以显示于编辑界面的文本区域内，文本区域可以认为是编辑界面中的某个区域，用于显示目标视频的语音文本，如用于显示目标视频的语音文本中的第五文本，文本区域的具体位置及大小可以由相关人员根据编辑界面的情况进行设置。
在一个实施方式中，文本区域中的无效文本自成一段，如可以将“停顿”文本单独成行，同时展示停顿时长。
对第五文本的触发操作可以用于触发将目标视频的播放进度调整第二时间节点，如对第五文本的触发操作可以为点击第五文本的操作；第二时间节点即为第五文本的起点位置在目标视频中所对应的时间节点。
具体的，在编辑界面的视频区域播放目标视频之后，还可以响应于对第五文本的触发操作，将目标视频的播放进度调整至第二时间节点，并从第二时间节点继续播放目标视频。在此基础上，通过响应于第五文本的触发操作，实现了对目标视频播放进度的调整，以此实现在目标视频中对相应文本的定位，便于用户观看相应文本所对应的视频片段。
在一个实施例中，所述编辑轨道片段上还展示有时间标识，在所述编辑界面的视频区域播放所述目标视频之后，还包括：
响应于对所述目标标识的位置调整操作，确定所述目标标识的目标位置所位于的第三时间线区间，所述目标位置为所述位置调整操作执行完毕时所述目标标识在所述编辑轨道片段上的位置；
如果所述第三时间线区间为所述无效文本的时间线区间，则将所述目标视频的播放进度调整至第三时间节点，并从所述第三时间 节点继续播放所述目标视频，其中，所述第三时间节点为所述第三时间线区间的起点位置或终点位置在所述目标视频中所对应的时间节点，或者，接收到所述位置进度调整操作之前所述目标视频最后播放至的时间节点；
如果所述第三时间线区间不为所述无效文本的时间线区间，则将所述目标视频的播放进度调整至第四时间节点，并从所述第四时间节点继续播放所述目标视频，其中，所述第四时间节点为所述目标位置在所述目标视频中所对应的时间节点。
时间标识用于在目标视频的编辑轨道片段中表征目标视频当前所播放至的时间节点，换言之，此时间标识可用于指示目标视频当前的播放进度对应的时间节点。当前应用程序在编辑界面的视频区域播放目标视频时，可以依据目标视频的播放进度，实时更新目标标识在目标视频的编辑轨道片段中的位置。目标标识的位置调整操作则可以理解为调整目标标识位置的操作，如目标标识的位置调整操作可以为点击编辑轨道片段中的某一位置a以将目标标识调整至该位置a的操作,目标标识的位置调整操作也可以为拖拽目标标识以将目标标识调整至位置a的操作等。目标位置可以认为是位置调整操作执行完毕时目标标识在编辑轨道片段上的位置，第三时间线区间即为目标标识的目标位置所位于的时间线区间。
第三时间节点可以是第三时间线区间的起点位置在目标视频中所对应的时间节点，或第三时间线区间的终点位置在目标视频中所对应的时间节点，也可以是接收到位置进度调整操作之前目标视频最后播放至的时间节点；第四时间节点可以认为是目标位置在目标视频中所对应的时间节点。
本步骤中，在编辑界面的视频区域播放目标视频之后，还可以响应于对目标标识的位置调整操作，对目标标识的位置进行调整。
示例性的，在对目标标识的位置调整操作的执行过程中，可以依据时间标识在所述编辑轨道片段中的位置，调整所述目标视频的播放进度。当该位置调整操作执行结束时，确定目标标识的目标位 置，对目标位置所位于的第三时间线区间进行确定，并根据第三时间线区间的不同分别对目标视频的播放进度进行不同的调整。
在一个实施方式中，当第三时间线区间为无效文本的时间线区间时，可以将目标视频的播放进度调整至第四时间节点，并从第四时间节点继续播放目标视频。示例性的，当拖拽目标标识至某无效文本的时间线区间A内时，本实施例自动将目标视频的播放进度调整至时间线区间A的终点位置，以从时间线区间A的终点位置继续播放目标视频，或者，将目标标识的位置还原为接收到位置调整操作之前目标标识最后位于的位置，并从该位置继续播放目标视频。当点击目标视频的编辑轨道片段上所标识的时间线区间A内的某位置时，本实施例自动将目标视频的播放进度调整至时间线区间A的起点位置，病从时间线区间A的起点位置继续播放目标视频。
在一个实施方式中，当第三时间线区间不为无效文本的时间线区间时，则可以将目标视频的播放进度调整至目标位置在目标视频中所对应的时间节点，并从该时间节点继续播放目标视频。示例性的，当拖拽目标标识至的目标位置b不位于无效文本的时间线区间内时，或者，当通过点击的方式将目标标识移动至的目标位置b不位于无效文本的时间线区间内时，本实施例则可以将目标视频的播放进度调整至目标位置b在目标视频中所对应的时间节点c，并从时间节点c继续播放目标视频。在此基础上，通过响应于对目标标识的位置调整操作，能够使得当调整目标标识的位置位于无效片段时，能够自动跳过无效文本所对应的视频片段或者从无效文本所对应视频片段的起点位置完整播放该视频片段；而当调整目标标识的位置不位于无效片段时，从此位置所对应时间节点处播放目标视频的功能。
图4为本公开实施例提供的另一种视频的编辑方法的流程示意图。本实施例中的方案可以与上述实施例中的一个或多个可选方案组合。可选的，所述响应于所述无效文本的调整操作，在所述目标 视频的编辑轨道片段上对所述无效文本的时间线区间进行调整，包括下述至少之一：响应于所述无效文本的第一调整操作，在所述目标视频的编辑轨道片段上对所述无效文本的时间线区间的长度进行调整；响应于所述无效文本的第二调整操作，对所述目标视频的编辑轨道片段上所标识的时间线区间的数量进行调整。如图4所示，该方法包括：
S210、通过对目标视频中的音频进行语音识别，确定所述目标视频的语音文本中的无效文本及所述无效文本的时间线位置，所述无效文本的时间线位置用于表示所述无效文本的语音音频在所述目标视频中的出现时间。
S220、在所述目标视频的编辑界面上展示所述目标视频的编辑轨道片段，并基于所述无效文本的时间线位置，在所述编辑轨道片段上标识所述无效文本的时间线区间，所述无效文本的时间线区间为所述无效文本的语音音频在所述目标视频中出现的时间区间。
S230、响应于所述无效文本的第一调整操作，在所述目标视频的编辑轨道片段上对所述无效文本的时间线区间的长度进行调整。
第一调整操作可以用于调整无效文本的时间线区间的长度，第一调整操作可以作用在目标视频的编辑轨道片段上，示例性的，第一调整操作可以为在目标视频的编辑轨道片段上拉伸或压缩某无效文本的时间线区间B的操作，如向左拖拽时间线区间B的起始位置的操作等。
本步骤可以响应于无效文本的第一调整操作，在目标视频的编辑轨道片段上对无效文本的时间线区间的长度进行调整，如当向左拖拽某时间线区间的左边界或向右拖拽某时间线区间的右边界时可以延长该时间线区间的区间长度，当向右拖拽某时间线区间的左边界或者向右拖拽某时间线区间右边界时可以缩短该时间线区间的区间长度。
S240、响应于所述无效文本的第二调整操作，对所述目标视频的编辑轨道片段上所标识的时间线区间的数量进行调整。
第二调整操作可以用于调整编辑轨道片段上所标识的时间线区间的数量，如第二调整操作可以作用在某调整控件上，每个无效文本可以对应一个调整控件，调整控件用于控制编辑轨道片段上是否标识此无效文本对应的时间线区间；第二调整操作也可以作用在编辑轨道片段的时间线区间上。
本步骤可以响应于无效文本的第二调整操作，对目标视频的编辑轨道片段上所标识的时间线区间的数量进行调整，本实施例不对调整的具体过程进行限定，只要能调整编辑轨道片段上所标识的时间线区间的数量即可。
S250、响应于所述无效文本的视频片段删除操作，将所述编辑轨道片段上位于所述无效文本的时间线区间内的视频片段从所述目标视频中删除。
本公开实施例提供的一种视频的编辑方法，通过响应于无效文本的第一调整操作和第二调整操作，能够在目标视频的编辑轨道片段上对无效文本的时间线区间的长度和数量进行调整，从而能够根据用户需求实现对目标视频的精确剪辑。
在一个实施例中，所述在所述目标视频的编辑界面上展示所述目标视频的编辑轨道片段，包括：
在所述编辑界面的轨道区域展示所述目标视频的编辑轨道片段，并在所述编辑界面的文本区域展示所述语音文本中的无效文本和非无效文本，其中，所述无效文本在所述编辑界面上展示为选中状态，所述非无效文本在所述编辑界面上展示为非选中状态。
轨道区域可以为编辑界面内的某个区域，用于展示目标视频的编辑轨道片段。选中状态可以理解为某文本处于被选中的状态，以此表征此文本将要被删除；未选中状态可以理解为某文本处于未被选中的状态，以此表征此文本不会被删除。
本实施例中，在目标视频的编辑界面上展示目标视频的编辑轨道片段的具体过程可以为：在编辑界面的轨道区域对目标视频的编辑轨道片段进行展示，并在编辑界面的文本区域对语音文本中的无 效文本和非无效文本进行展示，其中，无效文本在编辑界面上可以展示为选中状态，非无效文本在编辑界面上可以展示为非选中状态。在此基础上，实现了展示编辑轨道片段的同时，在编辑界面的文本区域展示语音文本中的无效文本和非无效文本；此外，默认无效文本展示为选中状态，能够提示用户可以对无效文本进行删除，并避免用户需要执行相应的选中操作选中停顿、重复等无效文本才能对其进行删除，进一步简化用户删除目标视频中的无效文本所需的操作。
图5为本公开实施例提供的另一种编辑界面的示意图，如图5所示，在编辑界面的轨道区域7展示有目标视频的编辑轨道片段，并在编辑界面的文本区域8展示有语音文本中的无效文本(如“停顿0.12s”或“重复”)和非无效文本(如“我的”)，其中，无效文本在编辑界面上展示为选中状态，非无效文本在编辑界面上展示为非选中状态。
在一个实施例中，所述在所述目标视频的编辑轨道片段上对所述无效文本的时间线区间的长度进行调整，包括：
在所述目标视频的编辑轨道片段上对第一文本的第一时间线区间的长度进行调整，并更新所述文本区域中所展示的目标文本，所述目标文本包括所述第一文本和/或与所述第一文本相关联的第二文本。
第一文本可以是无效文本，如第一触发操作所针对时间线区间所属的文本。第一时间线区间即为第一文本的时间线区间。目标文本可以是指对应需要进行调整的文本，如目标文本可以包括第一文本和/或与第一文本相关联的第二文本，第二文本可以为与第一文本的时间线区间相邻时间线区间对应的文本，也可以为与第一文本的时间线区间相邻的时间线区间缩减后的新时间线区间对应的文本。
具体的，在目标视频的编辑轨道片段上对第一文本的第一时间线区间的长度进行调整的同时，需要对文本区域中所展示的目标文本进行更新，更新的具体内容可以由第一调整操作的具体操作来确 定。在此基础上，能够在调整第一时间线区间长度的同时，在文本区域将调整部分对应的文本进行实时更新，以精确化调整无效文本的时间线区间对应的时长。
在一个实施例中，所述第一调整操作包括长度延长操作，所述更新所述文本区域中所展示的目标文本，包括：
将所述第二文本中与所述第一时间线区间的延长部分对应的文本内容移动至所述第一文本中。
长度延长操作可以认为是延长第一时间线区间长度的操作，如长度延长操作可以为向左拖拽第一时间线区间的起始位置或者向右拖拽第一时间线区间的终止位置的操作。
在一个实施方式中，当在编辑轨道片段上延长第一文本的第一时间线区间的长度时，可以在文本区域同步将第二文本中与第一时间线区间的延长部分对应的文本内容移动至第一文本中，示例性的，当第一调整操作为向左拖拽第一时间线区间的起始位置的操作时，第二文本为位于第一时间线区间左侧的时间线区间对应的文本，此时，需要将第二文本中与第一时间线区间的延长部分对应的文本内容移动至第一文本中。
在一个实施方式中，长度延长操作可以支持将相邻非无效文本中的部分文本移动至第一文本中，当第二文本为无效文本时，则可以支持或不支持进行长度延长操作。
图6为本公开实施例提供的一种更新目标文本的示意图，如图6所示，当由位置A向右拖拽第一文本9对应的第一时间线区间的终点位置至位置B时，可以在目标视频的编辑轨道片段上对第一文本9的第一时间线区间的长度进行延长，同时将第二文本10中与第一时间线区间的延长部分对应的文本内容(如“太阳”)移动至第一文本9中。
在一个实施例中，所述第一调整操作包括长度缩短操作，所述更新所述文本区域中所展示的目标文本，包括：
将所述第一文本中与所述第一时间线区间的缩短部分对应的文 本内容移动至所述第二文本中；或者
在所述文本区域中新增第二文本，并将所述第一文本中与所述第一时间线区间的缩短部分对应的文本内容移动至所述第二文本中。
长度缩短操作可以认为是缩短第一时间线区间长度的操作，如长度缩短操作可以为向右拖拽第一时间线区间的起始位置或向左拖拽第一时间区间的终止位置的操作。
在一个实施方式中，当在编辑轨道片段上缩短第一文本的第一时间线区间的长度时，可以根据第一文本内容的不同来确定文本区域中所展示目标文本的更新方式，示例性的，当第一文本内容为停顿时，可以将第一文本中与第一时间线区间的缩短部分对应的文本内容移动至第二文本中；而当第一文本内容为重复文本、无效词或除停顿、重复和无效词之外的正常文本时，则可以在文本区域中新增第二文本，并将第一文本中与第一时间线区间的缩短部分对应的文本内容移动至新增的第二文本中。
图7为本公开实施例提供的另一种更新目标文本的示意图，如图7所示，当由位置A向左拖拽第一文本9对应的第一时间线区间的终点位置至位置C时，可以在目标视频的编辑轨道片段上对第一文本9的第一时间线区间的长度进行缩短，同时将第一文本9中与第一时间线区间的缩短部分对应的文本内容(如“停顿0.02s”)移动至第二文本10中。
图8为本公开实施例提供的另一种更新目标文本的示意图，如图8所示，当由位置D向右拖拽第一文本11对应的第一时间线区间的终点位置至位置E时，可以在目标视频的编辑轨道片段上对第一文本11的第一时间线区间的长度进行缩短，同时可以在文本区域中新增第二文本12，并将第一文本11中与第一时间线区间的缩短部分对应的文本内容(即“重复”)移动至第二文本12中。
在一个实施例中，所述无效文本为所述轨道区域中处于选中状态的文本，所述响应于所述无效文本的第二调整操作，对所述目标 视频的编辑轨道片段上所标识的时间线区间的数量进行调整，包括下述至少之一：
