具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
本公开的发明人发现，在相关技术中，创作者制作素材包的方式较为繁琐，诸如需要先制作效果视频，再从效果视频中扣取素材得到素材包。
鉴于此，本公开提供了一种素材包的生成方法，以简化素材包的制作过程。
图1为本公开实施例提供的一种素材包的生成方法的流程示意图。该方法可应用于第一客户端，第一客户端诸如可以通过手机、计算机等实现。本公开实施例对第一客户端的实现方式不进行限制。生产端用户(诸如素材包的创作者)可以利用第一客户端生成素材包。如图1所示，该方法主要包括如下步骤S102至步骤S106。
步骤S102，获取目标视频的编辑记录文件。目标视频是通过编辑操作将指定素材合成到初始视频上而得到的视频。
在一些实施方式中，可以响应于接收到用户发起的素材包生成指令，获取目标视频的编辑记录文件。其中，目标视频是通过编辑操作将指定素材合成到初始视频上而得到的视频。也即，目标视频可以是用户(素材包的创作者)采用待制作素材包的指定素材对初始视频进行编辑得到的视频。目标视频也可称为素材包的示例视频。
在本公开的一些实施例中，编辑记录文件包括用于记录编辑操作的编辑记录信息以及初始视频和指定素材。诸如，在本公开实施例中的视频编辑软件中，可以将用户制作视频的编辑过程进行完整记录，得到针对初始视频的剪辑操作序列，在剪辑操作序列中的每个剪辑操作所用的素材以及素材在初始视频中的具体使用方式等，从而形成编辑记录文件。例如，编辑记录文件是视频编辑软件为了记录视频编辑状态而使用的一种协议，其可存储用户在编辑视频过程中的所有信息，诸如，用户在视频编辑过程中所添加的元素、调整的参数、用户的操作等，当用户重新打开视频时，即可自动读取该视频对应的编辑记录文件，从而还原上一次的编辑状态。
在本公开实施例中，无需素材包的创作者从视频中抠取素材，而是可直接获取视频的编辑记录文件，以通过编辑记录文件生成素材包。
步骤S104，基于编辑记录文件获取目标素材以及目标素材的应用信息。应用信息包含有目标素材在目标视频中的编辑记录信息。
这里，目标素材属于指定素材。在一些实施示例中，可以将指定素材中的全部素材均作为目标素材。考虑到素材包的创作者可能不希望将所有素材都打包分享，因此也可以仅将素材包的创作者从指定素材中选择的部分素材作为目标素材。目标素材可以根据用户需求而确定，在此不进行限制，在已知编辑记录文件的基础上，可以直接从中提取目标素材的应用信息。应用信息包含目标素材在目标视频中的编辑记录信息。编辑记录信息诸如可以包括以下中的一种或多种：位置信息、旋转信息、缩放信息、轨道信息。在此基础上，应用信息还可以包含目标素材的获取路径。该获取路径用于指示获取素材的方式。诸如素材是本地上传的素材时，该素材的获取路径可以为文件获取路径，而素材是从网络上下载的素材时，该素材的获取路径可以为网络获取路径。
另外，本公开实施例中的素材包括但不限于视频、图片、贴纸、文字、音乐、特效、滤镜中的一种或多种。编辑记录信息诸如包括素材在视频中的位置信息、缩放信息、轨道信息中的一种或多种，具体可根据素材类别确定。诸如，素材为视频、图片、贴纸或文字时，对应的应用信息都可包含有位置信息、缩放信息和轨道信息，在此基础上，素材为图片、贴纸和文字时，还可以进一步包含旋转信息；素材为音乐或特效时，对应的应用信息则可包含有轨道信息。以上仅为示例，不应当被视为限制。
步骤S106，基于目标素材及其应用信息生成用于视频编辑的素材包。已知目标素材及其应用信息后，第一客户端可以自动基于目标素材及其应用信息进行打包，生成用于视频编辑的素材包。后续可以将生成的素材包发送给服务器，以使服务器将该素材包发 布在指定平台。通过指定平台实现素材包分享，其他用户可以在指定平台上下载并使用该素材包。
综上，本公开实施例提供的上述素材包的生成方法，所述方法应用于第一客户端，包括：获取目标视频的编辑记录文件，其中，所述目标视频是通过编辑操作将指定素材合成到初始视频上而得到的视频，编辑记录文件包括用于记录所述编辑操作的编辑记录信息以及所述初始视频和所述指定素材；基于所述编辑记录文件获取目标素材以及所述目标素材的应用信息，其中，所述应用信息包含有所述目标素材在所述目标视频中的编辑记录信息，且所述目标素材属于所述指定素材；和基于所述目标素材及其应用信息生成用于视频编辑的素材包。对于素材包的生成者而言，无需再从视频中逐一抠取素材制作素材包，直接根据视频编辑记录文件中的目标素材及应用信息即可生成素材包，简化了素材包的制作过程。
在一些实施方式中，基于编辑记录文件获取目标素材以及目标素材的应用信息的步骤，可以包括如下两个主要步骤(1)至(2)。
步骤(1)，将指定素材中的所有素材均作为目标素材，或者，将目标素材中携带有发布许可标识的素材作为目标素材。也即，在实际应用中，可以参照如下两种实施示例实现：
实施示例一：将指定素材中的所有素材均作为目标素材。倘若没有指定，可以默认将所有的指定素材均作为目标素材。
实施示例二：将目标素材中携带有发布许可标识的素材作为目标素材。在实际应用中，可以为创作者提供素材勾选项，创作者可以对其制作目标视频所使用的指定素材进行勾选，为勾选的指定素材赋予发布许可标识。这种方式充分考虑到创作者的需求，仅发布创作者允许的素材，对于一些创作者并不希望被广泛使用的私人素材则可不发布。
可以根据实际情况灵活选用上述实施示例一和/或实施示例二实现，也可以为用户提供“将所有素材均发布”或者“仅发布部分素材”的选项，在用户选择“将所有素材均发布”时，则可采用上述实施示例一实现，在用户选择“仅发布部分素材”的选项时，则可采用上述实施示例二实现。尤其对于目标素材中包含有创作者的本地素材的情况下，用户(素材包的创作者)可以通过素材勾选项为想要发布的指定素材赋予发布许可标识，可以充分尊重用户意愿，仅将用户想要上传的素材进行打包。其中，本地素材即为用户通过第一客户端上传的素材，诸如，为创作者在本地相册中上传的图像，或者创作者在某本地文件夹中上传的贴纸、视频等素材。换言之，本地素材并非网络公开下载的素材， 而是终端本地存储的素材。创作者可以根据需求而指定可以打包进素材包的素材，灵活性更强。
步骤(2)，将编辑记录文件中记录的目标素材在目标视频中的编辑记录信息作为目标素材的应用信息，其中，编辑记录信息包括以下中的一种或多种：位置信息、旋转信息、缩放信息、轨道信息。在实际应用中，不同类型的素材所对应的编辑记录信息可能并不相同，每种素材都可以对应一种或多种编辑记录信息，在此不进行限制。
为了充分有效地节约素材包的内存，目标素材的应用信息还包含目标素材的获取路径，在此基础上可以不将目标素材直接打包在素材包中，而是将目标素材的标识以及应用信息(包含有该目标素材的获取路径以及编辑记录信息)存放在素材包中，以便于素材包的使用者可以清楚获知如何获取目标素材，以及如何使用目标素材。
素材包的创作者在创作素材包的过程中，大多会使用个人独创的本地素材，诸如独创的图片、贴纸、音乐、小视频等，从而为其它用户提供新鲜素材，因此目标素材通常都会包含有至少一种本地素材。而且在很多情况下，素材包的创作者不仅会利用本地素材，还会利用远端素材，也即其所制作的素材包中不仅包含有创作者的本地素材，还包含有创作者通过网络下载的远端素材(原有远端素材)，其中，远端素材为存储在服务器中且可被公开下载的素材。本公开实施例可直接识别出目标素材中的素材类型(本地/远端)，并进行相应处理。诸如，为了节约素材包的内存，可以不在素材包中存放本地素材，而是先将本地素材发布在服务器处，将本地素材作为新的远端素材，之后素材包中只需存放原有远端素材以及新的远端素材(本地素材)的标识以及包含有素材获取路径和编辑记录信息的应用信息。这种处理方式所需的素材包容量很小，非常便于下载以及传播。
在上述基础上，本公开实施例给出了基于目标素材及其应用信息生成用于视频编辑的素材包的具体实施方式，具体可参照如下步骤A至步骤C实现。
步骤A，将目标素材中的本地素材上传至服务器，以使服务器将本地素材转换为新的远端素材，其中，远端素材为存储在服务器中且可被公开下载的素材。
在实际应用中，可以将目标素材中的本地素材自动上传至指定的服务器，然后由服务器将本地素材在指定平台上发布，发布后的本地素材即为新的远端素材。素材的存储以及发布可以均通过同一服务器执行，也可通过不同的服务器执行。诸如，将本地素材上传至存储服务器，然后由存储服务器在存储本地素材的基础上，进一步将本地素材发送给素材服务器，由素材服务器将本地素材在指定平台上发布。
步骤B，接收服务器返回的新的远端素材对应的远端素材标识，将本地素材的应用信息中记录的获取路径替换为新的远端素材的远端素材标识，并将替换后的应用信息作为新的远端素材对应的应用信息。
服务器在将本地素材发布为远端素材时，会为远端素材新赋予相应的素材标识，该素材标识可以称为远端素材标识或者资源ID，远端素材标识也即远端素材的身份标识，不同远端素材对应的远端素材标识不同。可以理解的是，对于素材包的创作者而言，其使用存储在本地的素材进行素材包创作，因此在编辑记录文件中针对本地素材记录的是文件获取路径，而倘若将本地素材公开发布为新的远端素材，其他用户在下载素材包时只需要获知素材包中的远端素材的远端素材标识即可，通过远端素材标识便可从服务器下载到相应的远端素材，通过上述方式即可使得其他用户能够便捷地利用到素材包创作者的本地素材。
另外应当注意的是，应用信息中的编辑记录信息仍旧保持不变，也即，对于目标素材中的本地素材而言，其对应的应用信息包括本地素材在目标视频中的编辑记录信息(简称为素材编辑记录信息)和本地素材的文件获取路径，在通过服务器将本地素材转变为远端素材后，该远端素材对应的应用信息包括上述素材编辑记录信息和远端素材对应的远端素材标识。在本公开实施例中，远端素材标识和文件获取路径均可用于表征素材的具体获取方式，均属于应用信息中所包含的目标素材的获取路径的表达形式。
步骤C，基于新的远端素材及其应用信息，以及目标素材中原有远端素材及其应用信息生成用于视频编辑的素材包。其中，原有远端素材为第一客户端在生成目标视频的过程中从服务器下载的素材。
由于已将创作者的本地素材转为他人均可使用的远端素材，在此基础上则可基于新的远端素材及其应用信息，以及原有远端素材及其应用信息可直接生成用于视频编辑的素材包。可以理解的是，通过上述方式所得的素材包中的素材均为远端素材，一部分是创作者将本地素材通过服务器发布而成的新的远端素材，一部分为创作者通过网络下载的原有远端素材。
在上述方式中，可以直接基于编辑记录文件获取本地素材以及应用信息，并将本地素材发布为新的远端素材，将本地素材的应用信息中的获取路径替换为远端素材标识，而应用信息的其余内容保持不变，最后基于新的远端素材及其应用信息即可生成素材包。对于素材包的生成者而言，无需再从视频中逐一抠取素材制作素材包，简化了素材 包的制作过程，而且素材包中无需存储素材，只需存储素材的获取路径以及编辑记录信息即可，所需内存很小，便于下载和传播。
在前述基础上，可认为本公开实施例重新定义了一种素材包协议，素材包协议清楚指示了素材的应用方式。换言之，素材包协议也可以理解为上述素材应用信息的集成内容，而本公开实施例提供的素材包则包含素材集合以及素材包协议(即素材的应用信息)。可参见图2所示的一种素材包协议示意图，示意出了素材包可能包含的多种素材对应的应用信息。图2简单示意出了视频、图片、贴纸、文字、音乐、特效等素材类型，以及每种素材类型对应的应用信息。其中，文件路径即为前述本地素材的获取路径，资源ID即为前述远端素材标识，文件路径/资源ID都指示了素材的获取方式。应当注意的是，图2仅是简单示例，不应当被视为限制，在实际应用中素材不局限于此，诸如可能还包含滤镜、音效等。而且在图2中列出的元素都是可选可组装的，不一定同时具备，具体可根据实际需求以及具体的视频编辑软件进行定制。总而言之，素材包需要记录素材的所有信息，以便后续应用时可完全还原各素材的效果。另外，图2中列出的素材包是创作者最初的素材包，还未经发布，本地素材的文件路径还未经替换，因此显示有一些素材可对应文件路径(即可为本地素材)，一旦本地素材发布，则其对应的文件路径则被替换为相应的远端素材的远端素材标识，最终形成的素材包中所包含的所有素材对应的都是资源ID，不会再对应文件路径。在实际应用中，相比于现有素材包仅是素材集合，本公开实施例提供的素材包，在包含素材集合的基础上还包含有上述素材包协议，也即，包含有素材以及相应的应用信息。应用信息指示了如何使用素材以及素材的获取方式，从而使素材包的下载者清楚获知各素材在视频中的应用方式，能够完全还原素材包的创作者在视频中使用素材的效果。
在一些实施方式中，为了进一步提升素材包的生成效率以及使用便捷性，可以保留原有编辑记录文件不被更改，而为编辑记录文件创建副本，然后直接在副本的基础上进行处理得到的素材包，也即将编辑记录文件改造为素材包，以便素材包的下载者可以直接应用该素材包(改造后的编辑记录文件)。具体的，素材包的下载者无需再逐一将素材包中各个素材添加至视频中，而是下载了该素材包后，即可直接将素材包作为编辑记录文件使用在所需编辑的视频中，将创作者在视频中使用素材的具体方式(诸如位置、旋转、缩放、轨道等)达到完全还原。基于此，上述将本地素材的应用信息中记录的获取路径替换为新的远端素材的远端素材标识，并将替换后的应用信息作为新的远端素材对应的应用信息的步骤，可以参照如下步骤a至步骤b执行。
步骤a，对编辑记录文件进行复制，得到编辑记录文件的副本。
步骤b，对副本进行如下处理：将副本中所包含的本地素材删除，以及将本地素材的应用信息中记录的获取路径替换为新的远端素材的远端素材标识，并将替换后的应用信息作为副本中记录的新的远端素材对应的应用信息。在一些具体的实施方式中，可以删除本地素材及相关信息，并根据映射关系将本地素材对应的获取路径替换为远端素材标识，其余均可保持不变。通过这种简单巧妙的方式，无需重写应用逻辑，即可利用已有的编辑记录文件更改为可直接应用的素材包。
在前述基础上，基于新的远端素材及其应用信息生成用于视频编辑的素材包的步骤，包括：基于处理后的副本生成用于视频编辑的素材包，其中，处理后的副本包含有新的远端素材的远端素材标识及相应的应用信息。示例性地，可以参照如下步骤(1)至(3)实现。
步骤(1)，获取指定的素材包封面，并将素材包封面上传至服务器。素材包封面可以由创作者指定，如果未指定则可选用默认素材包封面。
步骤(2)，获取预设的素材包可选信息，其中，素材包可选信息包括以下中的一种或多种：目标视频、素材版本信息、素材兼容信息。目标视频即为经多种素材编辑得到的示例视频，可以根据实际需求确认是否将目标视频放在素材包中。在一些实施方式中，可以将目标视频放在素材包中。另一些实施方式中，可以令素材包中不包含目标视频，而是将目标视频作为独立于素材包并与素材包关联的材料，从而使素材包的容量尽可能小。其他用户可以仅下载素材包，然后在需要查看素材包的使用示例时再下载或在线查看与其关联的目标视频。上述素材版本信息和素材兼容信息均可认为属于extra.json扩展文件，用于记录一些处理素材包的特殊逻辑，诸如素材包在不同终端下的具体应用方式。示例性地，素材在iOS下可正常使用的大小为200*200,但在android下可正常使用的大小则为300*300。
步骤(3)，将素材包封面、处理后的副本和获取到的素材包可选信息进行打包压缩处理以得到压缩包，将压缩包作为用于视频编辑的素材包。示例性地，可以将素材包封面、处理后的副本和获取到的素材包可选信息打包生成Zip包，然后发布至后台服务器，从而实现素材包的发布与分发。
进一步，本公开实施例提供了将本地素材的应用信息中记录的获取路径替换为新的远端素材的远端素材标识的一种技术实现方式，包括：将本地素材的应用信息中记录的获取路径删除；和在本地素材的应用信息中，将本地素材的标识字段更改为新的远端素 材的远端素材标识。为了能够标识每个远端素材的下载来源，在本公开一些实施例中，目标素材中的远端素材携带有素材来源标识，素材来源标识用于指示远端素材的素材存储位置。素材来源标识可用于区分下载远端素材的平台。在将目标素材中的本地素材通过服务器转换为新的远端素材后，新的远端素材的远端素材标识也可通过服务器获取。在实际应用中，可以根据素材来源标识确定待下载该远端素材的目标平台，然后再根据远端素材标识从目标平台上下载相应的远端素材。也即，可以在素材包中为每个远端素材附加用于标识下载来源的额外字段，示例性地，将素材来源标识字段设为source_plaform，source_plaform的取值诸如可以为0、1、2、3、4等，不同的取值代表不同的下载平台。在实际应用中可用于下载素材的平台(或服务器)可以有多种，该取值可作为素材下载平台的标识。为便于理解，以下对将目标本地素材的标识字段更改为远端素材标识(remote_id)以及新增素材来源标识(source_platform)进行示例性说明：
1)video(视频)素材:使用remote_id替换原materials.videos中的material_id，增加source_platform＝1；
2)audio(音乐)素材:使用remote_id替换原materials.audios中的music_id，增加source_platform＝2；
3)image(图片)素材:使用remote_id替换原materials.image中的image_id，增加source_platform＝1；
4)sticker(贴纸)素材:使用remote_id替换原materials.image中的sticker_id，增加source_platform＝1；
5)text(文本)素材:先删除文本片段，新增文字模板片段，source_platform＝1。
上述以上仅为示例性说明，不应当被视为限制。在素材包的应用过程中，可根据source_platform确定素材获取平台，根据remote_id从素材获取平台下载相应的远端素材，即可得到素材包中的所有素材，并基于素材包协议对素材包进行直接应用。
在前述基础上，本公开实施例提供了将创作者现有的编辑记录文件转换为新素材包进行发布的示例，参见图3所示的一种素材包生成流程示意图，示意出了将编辑记录文件转换为素材包的具体方式，且清楚标注了各部分涉及的执行主体。在该图中示意出终端可基于编辑记录文件解析，得到创作者编辑视频所采用的本地素材、原远端素材和素材包视频、封面等；本地素材会通过服务器发布为远端素材，然后再在获取到服务器反馈的远端素材标识后修改草稿协议(即为编辑记录文件)，具体的，修改方式即为前述将 本地素材的获取路径修改为经发布得到的远端素材对应的远端素材标识，而素材包视频、封面等则可以在上传至服务器后，与原远端素材、修改后的草稿协议进行打包，得到新素材包，最后再通过服务器发布该新素材包。应当注意的是，图3重点在于阐述不同类型的材料(本地素材、远端素材、素材包视频或封面)在生成素材包过程中会采用不同的处理方式，诸如本地素材需要通过服务器发布为远端素材，以及针对该本地素材修改协议(将编辑记录文件中该本地素材的获取路径修改为远端素材标识)；原远端素材直接参与打包即可，无需其它处理；素材包视频、封面则在上传至服务器进行存储后再参与打包。在实际应用中，不一定以上三种类型材料全部都具备，诸如，部分创作者仅采用本地素材(诸如本地视频、本地音乐、本地贴纸、文本等)进行视频编辑，因此素材包中不会有原远端素材(诸如贴纸、特效、滤镜、文字模板、音乐、音效等)；部分创作者可能选择不将素材包视频打包在素材包中，因此也可能不会有素材包视频等。但无论何种情况，对于创作者制作素材包而言，素材包中会涉及到本地素材。
进一步，在前述基础上，本公开实施例提供了如图4所示的一种本地素材处理流程示意图，示意出将本地素材发布为新的远端素材的流程示意。如图4所示，编辑记录文件中包含有本地素材(本地图片、本地音频)还有原远端素材(远端贴纸、特效等)。可将本地素材上传至存储服务器，并发布至素材服务器，以便公众使用。例如，本地素材在上传至存储服务器后可确定相应的URL和KEY，并根据URL和KEY发布至素材服务器，形成远端素材。在经服务器发布之后，即可获取服务器的远端素材标识(remote_id)，并采用远端素材替换本地素材，因此生成的素材包中包含的都是远端素材，具体的，原有的本地图片已被替换为远端图片，本地音频被替换为远端音乐。另外，图4中示意出还可为新的远端素材新增素材来源标识(source_platform)，以标识素材来源。
在一些实施例中，上述方法还包括：响应于接收到素材包标题信息以及素材包概述信息，将素材包标题信息和素材包概述信息与素材包进行关联。
在实际应用中，可以在用户终端的界面上提供素材包标题框和素材包概述框，以便于素材包的创作者可在素材包标题框中输入其所创作的素材包的标题，以及在素材包概述框中输入素材包的主题描述等，以便使其它下载素材包的用户能够更清楚地获知素材包的主题风格，从而根据需求快速判别是否需要下载该素材包。
综上所述，本公开实施例提供的上述素材包生成方法，对于素材包的生成者而言，无需再从视频中逐一抠取素材制作素材包，简化了素材包的制作过程，提升了素材包的 生成效率，而对于素材包的使用者而言，由于素材包中携带有素材的应用信息，因此使用素材包更为方便。
创作者在采用素材制作效果视频(前述目标视频)，即可根据需求确定所需的目标本地素材，并实现一键发布素材包，非常方便快捷。而素材包中不仅记录有素材集合，而且还可以包含素材包协议，具体而言记录每一个素材的位置信息，缩放信息，轨道信息等使用记录信息以及素材的具体获取方式(诸如远端素材标识)。其他用户在一键应用时，可以自动根据标识获取素材，并根据使用记录信息直接还原每一个素材在视频中的展示效果。且素材包是直接基于编辑记录文件所得，其他用户可以直接将素材包整体应用，与相关技术中素材包仅包含素材集合，素材包的使用者在拿到素材包后不清楚每个素材具体如何应用，还需要反复调整而言，本公开实施例提供的上述方式提升了素材包的使用便捷性。
本公开的发明人还发现，在相关技术中，制作得到的素材包仅是各种素材的集合，其他用户拿到素材包后不知如何具体应用其中的素材，使用素材包也非常不方便。
鉴于此，本公开的实施例还提供一种视频编辑方法，以提升素材包的使用便捷性。
在前述素材包的生成方法的基础上，本公开实施例提供了一种视频编辑方法。该方法应用于第二客户端。第二客户端诸如可以通过手机、计算机等实现，本公开实施例对第二客户端的实现方式不进行限制。消费端用户(诸如素材包的使用者)可以利用第二客户端获取素材包，并利用素材包进行视频编辑。如图5所示，该方法主要包括如下步骤S502至步骤S506。
步骤S502，获取待编辑视频。待编辑视频可以是用户上传的待编辑的原始视频。
步骤S504，响应于接收到素材包应用指令，获取素材包应用指令对应的指定素材包。指定素材包是采用本公开实施例前述的任一项素材包的生成方法生成的，在此不再赘述。
在一些具体的实施示例中，可以响应于监测到素材包功能的触发操作，在第二客户端的界面上展示多个目标视频，每个目标视频对应一个素材包；和响应于监测到目标视频的选择操作，确定接收到素材包应用指令，且将被选择的目标视频对应的素材包作为素材包应用指令对应的指定素材包。
在实际应用中，视频编辑软件可以给用户提供视频编辑功能，并将多种视频编辑功能的标识展示在第二客户端的界面上。视频编辑功能包含有素材包功能。当检测到用户(素材包的使用者)点击素材包功能的标识或按键后，即可认为监测到素材包功能的触 发操作，进而在第二客户端的界面上展示多个目标视频。目标视频即为素材包的创作者生成并发布的视频。目标视频是通过编辑操作将目标素材合成到初始视频上而得到的视频。每个目标视频对应一个素材包。可以理解的是，一个素材包的创作者可以生成并发布多个素材包，视频编辑软件呈现在第二客户端的界面上的不同目标视频可能是由不同的素材包的创作者生成并发布的，在此不进行限定。通过将多个目标视频呈现在界面上的方式，便于素材包的使用者可以直观感受到素材包应用在视频中的效果，从而选择所需的素材包。在本公开实施例中，当监测到用户点击目标视频时，即认为用户需要该目标视频对应的素材包，因此可以直接将该目标视频对应的素材包作为素材包应用指令对应的指定素材包，非常方便快捷，且便于实现。
在一些实施例中，获取素材包应用指令对应的指定素材包包括：将指定素材包的标识发送给服务器，以通过服务器下载素材包应用指令对应的指定素材包。在实际应用中，可以将素材包的实际内容都存储在服务器侧，在确定用户所需的指定素材包时，第二客户端直接从服务器下载该指定素材包的内容即可，素材包中可直接包含有素材及应用信息。
步骤S506，基于指定素材包对待编辑视频进行编辑。
在一些实施例中，基于指定素材包对待编辑视频进行编辑包括：根据指定素材包中的素材的应用信息，将指定素材包中的素材合成到待编辑视频上。在实际应用中，第二客户端可以基于指定素材包中所包含的内容，自动将素材包中的素材按照应用信息合成在待编辑视频中，无需素材包的使用者再逐一采用素材包中的素材对视频进行编辑，提升了素材包的使用便捷性。
综上所述，本公开的实施例提供了一种视频编辑方法，其中，所述方法应用于第二客户端，包括：获取待编辑视频；响应于接收到素材包应用指令，获取所述素材包应用指令对应的指定素材包，其中，所述指定素材包是采用如前所述的素材包的生成方法生成的；和基于所述指定素材包对所述待编辑视频进行编辑。通过上述视频编辑方式，对于素材包的使用者而言，由于素材包中携带有素材的应用信息，可以直接基于素材包进行视频编辑，因此使用素材包更为方便。
为便于理解，在获取到指定素材包之后，本公开实施例进一步提供了一种如图6所示的素材包应用流程示意图，示意出其他用户在下载指定素材包之后的具体应用过程。在图4的基础上，在图6中进一步示意出可根据图片remote_id以及音乐remote_id请求素材服务器下载得到远端图片和远端音乐，从而实现编辑记录文件的还原。应当注意的 是，图6仅为示例性说明，重点在于表现被发布为新的远端素材的本地图片/本地音频在素材包使用过程中的还原流程，因此未示意原有远端素材(诸如远端贴纸、特效)等素材的应用过程。在实际情况下，素材包的原有远端素材也是需要凭借相应的remote_id请求素材服务器下载具体的远端素材。另外，在图6中编辑记录文件记录的是“本地图片”“本地音频”，主要用于表现其实质为创作者提供的本地图片/音频，但对于素材包的下载者而言，所得到的素材包(实质也为编辑记录文件)中的素材均为远端素材。
如图6所示，素材包的下载者获取的素材包实质为编辑记录文件，而如图3和图4所示，仅是将本地素材替换为远端素材以及将编辑记录文件的标识字段替换为远端素材标识，本质上编辑记录文件的格式没有被改动，因此，素材包还原而成的编辑记录文件的格式与原有的编辑记录文件的格式是一样，可以一键应用，直接在素材包的下载者所需编辑的视频上还原各个素材在目标视频中的效果。通过这种方式，可提升用户使用素材包进行视频编辑的便捷性。
对应于前述素材包的生成方法，本公开实施例提供了一种素材包的生成装置，该装置可应用于第一客户端，参见图7所示的一种素材包的生成装置的结构示意图，主要包括：文件获取模块702、信息获取模块704和素材包生成模块706。
