可以理解的是，上述通知和获取用户授权过程仅是示意性的，不对本公开的实现方式构成限定，其它满足相关法律法规的方式也可应用于本公开的实现方式中。
为了便于理解，下面，对本公开实施例涉及的概念进行说明。
终端设备：是一种具有无线收发功能的设备。终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴终端设备等。本公开实施例所涉及的终端设备还可以称为终端、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备也可以是固定的或者移动的。
在相关技术中，视频代理是对原始高清视频素材进行复刻或转码，得到代理文件，其中，代理文件的数据大小比原始视频文件小，分辨率也较低，因此，用户可以对代理文件进行视频编辑，保证视频编辑的流畅度。目前，终端设备可以基于用户的选择，对视频素材进行视频代理。例如，终端设备可以向用户提供视频代理的选择窗口，若用户在视频编辑过程中选择视频代理，则终端设备可以对所有的视频素材进行视频代理。但是，视频代理需要用户启用，并且，终端设备只能对所有的视频素材进行视频代理，这样会导致终端设备的资源浪费，并且视频代理的灵活度较低。
为了解决相关技术中的技术问题，本公开实施例提供一种视频编辑方法，终端设备可以获取视频编辑的草稿，并在草稿的视频素材中，确定解码耗时大于或等于预设时长的第一视频素材，终端设备可以获取第一视频素材的分辨率，并根据第一视频素材的分辨率，确定第一视频素材的视频代理优先级，终端设备可以根据视频代理优先级，对第一视频素材进行视频代理，得到第一视频素材对应的第二视频素材，其中，第二视频素材的分辨率和/或码率小于第一视频素材，终端设备对草稿进行预览时，以第二视频素材代替第一视频素材进行渲染。在上述方法中，由于终端设备可以在视频编辑的草稿中，对解码耗时较长的第一视频素材进行视频代理，即，获取第一视频素材对应的分辨率和/或码率较低的第二视频素材，这样，终端设备可以准确的对草稿中的视频素材进行视频代理，提高终端设备的资源利用率，节约终端设备的资源，并且，由于终端设备可以根据视频代理优先级，对多个第一视频素材进行视频代理，进而可以提高视频代理的灵活度，并且，终端设备以第二视频素材代理第一视频素材进行渲染，进而可以避免视频编辑的卡顿现象，提高视频编辑的效率和流畅度。
下面，结合图1，对本公开实施例的应用场景进行说明。
图1为本公开实施例提供的一种应用场景示意图。请参见图1，包括：轨道1和轨道2，其中，轨道1和轨道2为视频编辑页面中的视频轨道，轨道1中包括视频素材A和视频素材B，轨道B中包括视频素材C，视频素材A、视频素材B和视频素材C都为视频编辑的草稿中的视频素材。若终端设备(图1未示出)确定视频素材C的解码耗时大于预设时长，则终端设备可以对视频素材C进行视频代理，得到视频素材D，其中，视频素材D的视频内容与视频素材C的视频内容相同，视频素材D的分辨率小于视频素材C的分辨率，视频素材D的码率小于视频素材C的码率。终端设备可以将轨道2中的视频素材C替换为视频素材D。这样，可以提高视频代理的准确度和灵活度，提高视频编辑的效率。
需要说明的是，图1只是对本公开实施例的应用场景的示例，并非对本公开实施例的应用场景的限定。
下面以具体地实施例对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本公开的实施例进行描述。
图2为本公开实施例提供的一种视频编辑方法的流程示意图。请参见图2，该方法可以包括：
S201、获取视频编辑的草稿，视频编辑的草稿中包括至少一个视频素材。
本公开实施例的执行主体可以为终端设备，也可以为设置在终端设备中的视频编辑装置。其中，视频编辑装置可以基于软件实现，视频编辑装置也可以基于软件和硬件的结合实现，本公开实施例对此不作限定。
其中，草稿可以为视频编辑过程中的初步编辑的版本或未完成的版本。例如，草稿可以为视频编辑过程中的临时阶段，草稿可以用于记录当前视频编辑的进度、用户对草稿中的多媒体素材(如，视频素材、音频素材等)的编辑操作等。
其中，视频编辑的草稿中可以包括至少一个视频素材。例如，视频编辑的草稿中可以包括一个视频素材，也可以包括多个视频素材，本公开实施例对此不作限定。例如，视频素材可以为未经编辑的视频文件，视频素材也可以为已经过初步编辑的视频文件，本公开实施例对此不作限定。
可选的，终端设备可以在存储器中获取视频编辑的草稿。例如，视频编辑应用的页面中可以包括草稿显示区域，草稿显示区域中可以包括多个草稿(存储器中预先存储的多个草稿)，响应于用户对任意一个草稿的点击操作，终端设备可以将用户点击的草稿，确定为视频编辑的草稿。例如，用户点击草稿之后，终端设备可以跳转至视频编辑页面，并加载用户点击的草稿，用户可以在视频编辑页面中对该草稿继续进行视频编辑。
需要说明的是，终端设备也可以根据其它任意可行的实现方式，获取视频编辑的草稿(如，终端设备可以接收服务器发送的视频编辑的草稿)，本公开实施例对此不作限定。
S202、在至少一个视频素材中，确定第一视频素材。
其中，第一视频素材为解码耗时大于或等于预设时长的视频素材。例如，第一视频素材也可以为存在解码性能问题的视频素材。例如，解码性能问题可以包括解码耗时较长、视频素材播放卡顿和视频素材播放丢帧等问题，本公开实施例对此不作限定。
可选的，终端设备中可以包括性能信息采集模块，终端设备可以通过性能信息采集模块，确定第一视频素材。例如，性能信息采集模块可以收集、分析出当前时间线播放场景下的每个视频素材、媒体资源信息(媒体资源格式等)、解码性能信息(解码能力等)、解码压力情况(如，高分辨率视频的解码压力大)等，这样，性能信息采集模块可以确定草稿中存在解码性能问题的第一视频素材，并且，性能信息采集模块可以上报第一视频素材，终端设备也可以在性能信息采集模块中获取第一视频素材。
可选的，终端设备可以根据如下可行的实现方式，在至少一个视频素材中，确定第一视频素材：将视频编辑的草稿划分为多个区间段，在多个区间段中，确定存在解码丢帧的目标区间段，根据目标区间段中的视频素材的片段，确定第一视频素材。
其中，每个区间段可以包括至少一个视频素材的片段。例如，终端设备可以将视频编辑的草稿划分为区间段1、区间段2和区间段3，其中，区间段1可以包括视频素材A的片段，区间段2可以包括视频素材A的片段和视频素材B的片段，区间段3可以包括视频素材B的片段。
其中，终端设备将视频编辑的草稿划分为多个区间段，具体可以为：在视频编辑页面中加载草稿，其中，视频编辑页面中包括时间轴，在时间轴中确定分割点，在分割点的位置，对视频编辑的草稿进行分割，将视频编辑的草稿划分为多个区间段。
其中，视频编辑页面加载草稿之后，视频编辑页面的时间轴上可以包括草稿中的视频素材和视频编辑素材，用户可以在视频编辑页面中对草稿进行视频编辑。
其中，分割点可以用于将视频编辑的草稿划分为多个区间段。例如，分割点可以为时间线上的点，通过分割点，可以将草稿划分为不同时间段的多个区间段。
可选的，终端设备可以沿着时间轴的方向，将视频素材的片段发生变化的位置，确定为分割点。例如，在时间轴上，若时间点1-时间点2之间包括视频素材A的片段，时间点2-时间点3之间包括视频素材A的片段和视频素材B的片段，时间点3-时间点4之间包括视频素材A的片段，则终端设备可以将时间点2和时间点3确定为分割点，并基于时间点2和时间点3，将草稿划分为3个区间段。
下面，结合图3，对划分多个区间段的过程进行说明。
图3为本公开实施例提供的一种划分多个区间段的过程示意图。请参见图3，包括：时间轴。其中，时间轴上包括视频素材A、视频素材B、视频素材C和视频素材D。其中，视频素材A、视频素材B、视频素材C和视频素材D都为视频编辑的草稿中的视频素材。终端设备(图3未示出)可以在时间轴上确定分割点1、分割点2、分割点3和分割点4。
请参见图3，分割点1左侧包括视频素材A的片段，分割点1的右侧包括视频素材A的片段和视频素材B的片段。分割点2的左侧包括视频素材A的片段和视频素材B的片段，分割点2的右侧包括视频素材B的片段和视频素材C的片段。
请参见图3，分割点3的左侧包括视频素材B的片段和视频素材C的片段，分割点3的右侧包括视频素材B的片段、视频素材C的片段和视频素材D的片段。分割点4的左侧包括视频素材B的片段、视频素材C的片段和视频素材D的片段，分割点4的右侧包括视频素材C的片段和视频素材D的片段。
请参见图3，终端设备可以基于分割点1、分割点2、分割点3和分割点4，将草稿划分为区间段a、区间段b、区间段c、区间段d和区间段e。其中，区间段a中包括视频素材A的片段。区间段b中包括视频素材A的片段和视频素材B的片段。
请参见图3，区间段c中包括视频素材B的片段和视频素材C的片段。区间段d中包括视频素材B的片段、视频素材C的片段和视频素材D的片段。区间段e中包括视频素材C的片段和视频素材D的片段。这样，终端设备可以基于视频素材在时间轴上的变化，将草稿划分为多个区间段，提高区间段的准确度，进而提高确定第一视频素材的准确度。
其中，目标区间段可以为存在解码丢帧的区间段。可选的，终端设备可以根据如下可行的实现方式，确定目标区间段：对视频编辑的草稿进行预览操作，针对于任意一个区间段，若区间段中的任意一个视频素材的片段在播放过程中丢帧，则将区间段确定为目标区间段。
例如，区间段中可以包括至少一个视频素材的片段，若该视频素材的片段发生丢帧现象，则终端设备可以将该区间段确定为目标区间段。例如，草稿中可以包括区间段1和区间段2，在用户对草稿进行预览的过程中，若区间段1中的任意一个视频素材的片段发生丢帧现象，区间段2中的每个视频素材的片段都未发生丢帧现象，则终端设备可以将区间段1确定为目标区间段。例如，在用户对草稿进行预览的过程中，每当时间播放一个区间后，终端设备可以确定该区间是否存在掉帧行为，若存在，则说明该区间内的视频素材需要进行视频代理，终端设备可以标记该区间，这样，终端设备可以准确的确定需要视频代理的第一视频素材，提高第一视频素材的准确度。
可选的，终端设备根据目标区间段中的视频素材的片段，确定第一视频素材，具体可以为：在目标区间段中的视频素材的片段中，确定目标片段，并将目标片段对应的视频素材，确定为第一视频素材。
其中，目标片段的分辨率大于或等于第一阈值。例如，目标区间段中可以包括视频素材1的片段、视频素材2的片段和视频素材3的片段，若视频素材1的片段的分辨率和视频素材2的片段的分辨率大于或等于第一阈值，则终端设备可以将视频素材1的片段和视频素材2的片段，确定为目标片段。
可选的，终端设备确定目标片段之后，可以确定该目标片段对应的视频素材的分辨率较高，因此，终端设备可以将该视频素材确定为第一视频素材，并对该第一视频素材进行视频代理。例如，目标区间段中可以包括视频素材1的片段和视频素材2的片段，若目标片段为视频素材1的片段，则终端设备可以确定第一视频素材为视频素材1，若目标片段为视频素材2的片段，则终端设备可以确定第一视频素材为视频素材2。
下面，结合图4，对终端设备确定第一视频素材的过程进行说明。
图4为本公开实施例提供的一种确定第一视频素材的过程示意图。请参见图4，包括：时间轴。其中，时间轴上包括视频素材A、视频素材B、视频素材C和视频素材D。其中，视频素材A、视频素材B、视频素材C和视频素材D都为视频编辑的草稿中的视频素材。终端设备(图4未示出)可以在时间轴上确定区间段a、区间段b、区间段c、区间段d和区间段e。
请参见图4，在对草稿进行预览的过程中，区间段d发生丢帧现象，因此，终端设备可以将区间段d中的视频素材B的片段、视频素材C的片段和视频素材D的片段确定为候选的片段。终端设备确定视频素材C的片段的分辨率大于第一阈值，因此，终端设备可以将视频素材C的片段确定为目标片段，并将视频素材C确定为第一视频素材。这样，终端设备可以将预览丢帧的视频素材确定为第一视频素材，提高第一视频素材的准确度，提高视频代理的准确度。
S203、根据第一视频素材，确定第二视频素材。
其中，第二视频素材的分辨率和/或码率小于第一视频素材。例如，第一视频素材与第二视频素材的视频内容相同，第二视频素材的分辨率小于第一视频素材的分辨率，第二视频素材的码率小于第一视频素材的码率。例如，由于第二视频素材为第一视频素材的视频代理的结果，因此，第二视频素材与第一视频素材保持一致性。例如，第一视频素材的时间戳与第二视频素材的视频戳相同，第一视频素材的音视频的开始播放的时间点与第二视频素材的音视频的开始播放的时间点相同，第一视频素材的颜色空间(如，RGB等)与第二视频素材的颜色空间相同，第一视频素材的元数据与第二视频素材的元数据相同，第一视频素材的音视频的结束播放的时间点与第二视频素材的音视频的结束播放的时间点相同，第一视频素材的时间基(用于时间戳的计算和转换)与第二视频素材的时间基相同，第一视频素材的平均帧率与第二视频素材的平均帧率相同，第一视频素材的基本帧率与第二视频素材的基本帧率相同。
可选的，终端设备可以根据如下可行的实现方式，对第一视频素材进行视频代理：获取第一视频素材的视频信息，根据视频信息，在第一代理模式和第二代理模式中，确定目标代理模式，并根据目标代理模式，对第一视频素材进行视频代理。
其中，视频信息可以包括第一视频素材的复杂度、兼容性、视频格式等任意信息，本公开实施例对此不作限定。
其中，第一代理模式可以为硬件设备或软件设备对第一视频素材进行代理的模式。例如，终端设备可以通过硬件设备，对第一视频素材的视频流进行代理转发，提高视频代理的效率。例如，第一代理模式可以侧重于文件转码能力，在解码和缓存侧，第一代理模式取帧可以不依据请求时间戳的方式取帧，第一代理模式可以按视频帧的顺序进行取帧(即，一帧一帧的取帧)，这样，可以保证终端设备获取的视频帧的时间戳与原视频素材中的视频帧的时间戳一致。
其中，第二代理模式可以为通过命令行对第一视频素材进行代理的模式。例如，终端设备可以基于ffmpeg(开源的多媒体处理工具集，用于记录转换视频)，对第一视频素材进行转码等操作，进而对第一视频素材进行视频代理。
可选的，若终端设备根据视频信息，判断第一视频素材可以由第一代理模式(目标代理模式)进行视频代理，则终端设备可以通过第一代理模式对第一视频素材进行视频代理，若终端设备根据视频信息，判断第一视频素材无法由第一代理模式进行视频代理，则终端设备可以通过第二代理模式对第一视频素材进行视频代理。
可选的，在终端设备通过第一代理模式对第一视频素材进行视频代理时，若终端设备通过第一代理模型对第一视频素进行视频材代理失败，则终端设备可以通过第二代理模式对第一视频素材进行视频代理。
下面，结合图5，对终端设备对第一视频素材进行视频代理的方法进行说明。
图5为本公开实施例提供的一种视频代理的方法示意图。请参见图5，包括：第一视频素材的视频信息和代理任务选择器。其中，代理任务选择器可以用于根据视频信息，确定视频代理方式。其中，代理任务选择器可以根据第一视频素材的视频信息，确定第一视频素材的视频代理方式为硬件或软件代理，或者，确定第一视频素材的视频代理方式为命令行代理。其中，若硬件或软件对第一视频素材进行视频代理失败时，终端设备(图5未示出)可以通过命令行代理，对第一视频素材进行视频代理。
可选的，视频编辑的进程可以为主进程，视频代理的进程可以为子进程，这样，视频代理任务不会对视频编辑的主进程产生影响，进而提高视频代理的稳定性。
可选的，终端设备对第一视频素材进行视频代理时，上述视频编辑方法还包括：获取对第一视频素材进行视频代理所需的设备资源，在设备资源大于或等于第二阈值时，停止对第一视频素材进行视频代理。
其中，设备资源可以包括终端设备进行视频代理所需的资源。例如，由于视频代理的进程存在一定的设备资源消耗，因此，终端设备可以确定视频代理使用的设备资源的第二阈值，若终端设备进行视频代理使用的设备资源大于该第二阈值，则终端设备可以停止对第一视频素材进行视频代理(如，暂停视频代理任务或删除视频代理任务等)，其中，设备资源可以包括中央处理器CPU、内存和图形处理器GPU，这样可以避免视频代理出现内存泄漏、CPU占用过高、GPU占用过高等影响到主进程的视频编辑的问题，进而提高视频代理的可靠性，提高用户的体验。
可选的，终端设备可以包括进程资源监控模块，其中，该进程资源监控模块可以对视频代理使用的设备资源进行监控，在设备资源大于或等于第二阈值时，该进程资源监控模块可以向终端设备中的代理任务调度模块(用于管理视频代理任务)发送提示消息，代理任务调度模块可以根据该提示消息，停止对第一视频素材进行视频代理。
下面，结合图6，对停止第一视频素材进行视频代理的过程进行说明。
图6为本公开实施例提供的一种停止视频代理的过程示意图。请参见图6，包括进程资源监控模块、代理任务调度模块和视频代理任务。其中，进程资源监控模块和代理任务调度模块都为终端设备(图6未示出)中的模块。进程资源监控模块可以监控使用的设备资源，在使用的设备资源大于第二阈值时，进程资源监控模块可以向代理任务调度模块发送提示消息，代理任务调度模块接收到提示消息之后，可以停止该视频代理任务。这样，终端设备通过进程资源监控模块，可以避免视频代理对视频编辑造成影响，提高视频编辑的效率，提高用户的体验。
S204、在对草稿进行预览时，以第二视频素材代替第一视频素材进行渲染。
其中，终端设备对草稿进行预览时，可以通过第二视频素材代替第一视频素材进行渲染，这样可以避免预览卡顿等问题。例如，草稿中的第一视频素材可以包括视频素材A和视频素材B，终端设备对视频素材A进行视频代理，得到视频素材a(第二视频素材)，终端设备对视频素材B进行视频代理，得到视频素材b(第二视频素材)，终端设备对草稿进行预览时，可以将视频素材A替换为视频素材a进行渲染，将视频素材B替换为视频素材b进行渲染。
本公开实施例提供一种视频编辑方法，终端设备可以获取视频编辑的草稿，将视频编辑的草稿划分为多个区间段，并在多个区间段中，确定存在解码丢帧的目标区间段，终端设备可以在目标区间段中，确定分辨率大于或等于第一阈值的目标片段，并将目标片段对应的视频素材，确定为第一视频素材，终端设备可以对第一视频素材进行视频代理，得到第二视频素材，并在对草稿进行预览时，以第二视频素材代替第一视频素材进行渲染。这样，终端设备可以准确的在草稿中，确定需要进行视频代理的第一视频素材，提高第一视频素材的准确度和灵活度，节约终端设备的资源，并且，在对草稿进行预览时，终端设备以第二视频素材代替第一视频素材进行渲染，进而可以提高视频编辑的效率，提高预览的流畅度。
在图2所示的实施例的基础上，下面，结合图7，对上述视频编辑方法中，根据第一视频素材，确定第二视频素材的方法进行详细的说明。
图7为本公开实施例提供的一种确定第二视频素材的方法示意图。请参见图7，该方法流程包括：
S701、获取第一视频素材的分辨率。
其中，终端设备可以根据任意可行的实现方式，获取第一视频素材的分辨率，本公开实施例对此不作限定。
S702、根据第一视频素材的分辨率，确定第一视频素材的视频代理优先级。
可选的，若第一视频素材的数量为1，则终端设备可以对该第一视频素材进行视频代理，若第一视频素材的数量大于1，则终端设备可以对多个第一视频素材进行排序，得到视频代理的顺序，进而根据该视频代理的顺序，对多个第一视频素材进行视频代理。
可选的，第一视频素材的分辨率与第一视频素材的视频代理优先级成正比。例如，第一视频素材的分辨率越大，第一视频素材的视频代理优先级越高，第一视频素材的分辨率越小，第一视频素材的视频代理优先级越低。例如，第一视频素材1的分辨率小于第一视频素材2的分辨率，终端设备可以确定第一视频素材1的视频代理优先级高于第一视频素材2的视频代理优先级。
S703、根据视频代理优先级，对第一视频素材进行视频代理，得到第一视频素材对应的第二视频素材。
可选的，终端设备可以按照第一视频素材的视频代理优先级，对多个第一视频素材进行视频代理，得到每个第一视频素材对应的第二视频素材。例如，视频代理优先级越高，视频代理的顺序越靠前，视频代理优先级越低，视频代理的顺序越靠后。例如，若第一视频素材1的视频代理优先级高于第一视频素材2的视频代理优先级，则终端设备对第一视频素材进行视频代理时，终端设备可以优先对第一视频素材1进行视频代理，在终端设备对第一视频素材1进行视频代理结束之后，终端设备再对第一视频素材2进行视频代理。
可选的，终端设备确定多个第一视频素材的多个视频代理优先级之后，终端设备可以按照视频代理优先级的顺序，对多个第一视频素材进行视频代理，其中，终端设备可以根据如下可行的实现方式，对多个第一视频素材进行视频代理：获取视频编辑的草稿对应的编辑模式，根据编辑模式，对第一视频素材进行视频代理。
其中，编辑模式包括代理模式和非代理模式。例如，代理模式为终端设备可以对第一视频素材进行视频代理的模式，非代理模式为终端设备不会主动对第一视频素材进行视频代理的模式。例如，代理模式可以为性能模式，在编辑模式为性能模式时，终端设备侧重于保证用户进行视频编辑过程中的流畅度，非代理模式可以为画质模式，在编辑模式为画质模式时，终端设备侧重保证编辑过程中的画质效果，因此，在画质模式下，终端设备不会主动对第一视频素材进行视频代理，避免第一视频素材的画质效果降低。
可选的，终端设备可以根据任意可行的实现方式，确定草稿对应的编辑模式，本公开实施例对此不作限定。
其中，终端设备根据编辑模式，对第一视频素材进行视频代理，具体可以为：若编辑模式为代理模式，则对第一视频素材进行视频代理，若编辑模式为非代理模式，则响应于对编辑模式的切换操作，对第一视频素材进行视频代理。这样，终端设备可以灵活的对第一视频素材进行视频代理，提高视频代理的准确度和灵活度。
可选的，终端设备可以包括代理任务调度模块和代理任务执行模块，其中，代理任务调度模块可以用于管理视频代理任务，代理任务执行模块可以用于执行视频代理任务(如，图5所示的实施例的方法执行视频代理)。例如，代理任务调度模块可以根据草稿配置的编辑模式，决策是否对第一视频素材进行视频代理，若代理任务调度模块确定对第一视频素材进行视频代理，则代理任务调度模块可以通知代理任务执行模块对该第一视频素材进行视频代理。
其中，若草稿对应的编辑模式为代理模式，则代理任务调度模块可以通知代理任务执行模块对第一视频素材进行视频代理，在视频代理结束之后，终端设备可以在草稿中，将第一视频素材替换为第一视频素材对应的第二视频素材。
其中，若草稿对应的编辑模式为非代理模式，则终端设备可以显示编辑模式切换的窗口，并提示用户草稿中的视频素材存在解码性能问题，若用户选择将非代理模式切换为代理模式，则代理任务调度模块可以通知代理任务执行模块对第一视频素材进行视频代理，其中，若编辑模式由非代理模式切换为代理模式，则代理任务调度模块可以在性能信息采集模块中，获取已统计的区间段内的视频素材、以及未统计区间段内的视频素材，这样，在确定第一视频素材之后，代理任务调度模块可以通知代理任务执行模块对第一视频素材进行视频代理。
需要说明的是，若用户将草稿的编辑模式由代理模式切换为非代理模式，则终端设备可以将草稿中的第二视频素材，替换为第二视频素材对应的第一视频素材，进而提高视频编辑过程中的画质效果。
可选的，第二视频素材的分辨率可以为当前全屏窗口的0.5倍，这样可以降低视频代理对画质效果的影响，提高用户的体验。
本公开实施例提供一种确定第二视频素材的方法，获取第一视频素材的分辨率，根据第一视频素材的分辨率，确定第一视频素材的视频代理优先级，根据视频代理优先级，对第一视频素材进行视频代理，得到第一视频素材对应的第二视频素材。这样，终端设备可以优先对分辨率较高的第一视频素材进行视频代理，进而提高视频代理的效果，并且，终端设备可以结合草稿配置的编辑模式，对第一视频素材进行视频代理，进而可以提高视频代理的灵活度。
在上述任意一个实施例的基础上，下面，结合图8，对上述视频编辑方法的实现架构进行详细的说明。
图8为本公开实施例提供的一种实现视频编辑方法的架构示意图。请参见图8，包括：控制层和实现层。控制层中包括代理任务调度模块，实现层中包括解码链路1、解码链路2、……、解码链路n、信息采集模块、代理任务执行模块和进程资源监控模块，其中，每个解码链路可以解码一个视频素材，解码过程由引擎驱动。
请参见图8，信息采集模块可以获取每个解码链路的解码信息，并确定存在解码性能问题的第一视频素材。信息采集模块可以向代理任务调度模块上报第一视频素材，可选的，代理任务调度模块也可以主动从信息采集模块中获取第一视频素材。
请参见图8，代理任务调度模块可以控制视频代理任务进行进程间通信(Inter-Process Communication，IPC)，进而使得代理任务执行模块对第一视频素材进行视频代理。起重工，进程资源监控模块可以监控代理任务执行模块在执行视频代理的过程中，使用的设备资源。若该设备资源较大时，进程资源监控模块可以向代理任务调度模块发送提示信息，以使得代理任务调度模块控制代理任务执行模块停止对第一视频素材的视频代理。
在上述任意一个实施例的基础上，下面，结合图9，对上述视频编辑方法的过程进行说明。
图9为本公开实施例提供的一种视频编辑方法的过程示意图。请参见图9，包括：时间轴。其中，时间轴上包括草稿中的视频素材，其中，草稿中的视频素材包括视频素材A、视频素材B、视频素材C和视频素材D。终端设备(图9未示出)可以在时间轴上确定分割点1、分割点2、分割点3和分割点4。
请参见图9，终端设备可以基于分割点1、分割点2、分割点3和分割点4，将草稿划分为区间段a、区间段b、区间段c、区间段d和区间段e。其中，区间段a中包括视频素材A的片段。区间段b中包括视频素材A的片段和视频素材B的片段。区间段c中包括视频素材B的片段和视频素材C的片段。区间段d中包括视频素材B的片段、视频素材C的片段和视频素材D的片段。区间段e中包括视频素材C的片段和视频素材D的片段。
请参见图9，在对草稿进行预览的过程中，若区间段d发生丢帧现象，则终端设备可以将区间段d中的视频素材B的片段、视频素材C的片段和视频素材D的片段确定为候选的片段。终端设备确定视频素材C的片段的分辨率大于第一阈值，因此，终端设备可以对视频素材C进行视频代理，得到视频素材E。
请参见图9，终端设备可以将视频素材C替换为视频素材E。这样，在对草稿进行预览时，视频素材E的分辨率较低，进而可以保证用户对草稿进行预览的流畅度，并且，由于终端设备可以准确、灵活的确定需要进行视频代理的第一视频素材，进而可以提高视频代理的准确度和灵活度，并且可以节约视频代理的设备资源。
