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。
图1为本公开实施例提供的一种视频剪辑方法的流程示意图，该方法可以由视频剪辑装置执行，其中该装置可以采用软件和/或硬件实现，一般可集成在电子设备中。如图1所示，该方法主要包括如下步骤S102～步骤S108：
步骤S102，响应于用户在多个视频模板中选择目标视频模板，在剪辑页面上展示目标视频模板对应的模板视频帧图像以及多个素材类别的素材替换控件，其中，模板视频帧图像是将目标视频模板对应的模板素材按照目标视频模板对应的剪辑操作序列剪辑而成的。
在实际应用中，可以首先为用户展示多个视频模板，以供用户从中选择符合需求的目标视频模板。视频模板包括模板素材以及剪辑操作序列，不同视频模板对应的剪辑操作序列不同；剪辑操作序列指示了对模板素材进行剪辑所采用的剪辑操作的具体类型(诸如加特效、转场、加文字等)及多种剪辑操作的先后顺序。通过将模板素材按照剪辑操作序列进行剪辑即可得到视频模板对应的效果视频。在为用户展示多个视频模板时，可以展示视频模板的主题封面，也可以播放视频模板对应的效果视频，以便于用户直观感受到视频模板的剪辑效果。
在用户选中目标视频模板后，可以直接切换至剪辑页面，在剪辑页面上不仅显示目标视频模板对应的模板视频帧图像，而且还展示多个素材类别的素材替换控件，示例性地，素材类别包括影像类别、文字类别和音乐类别，相应的，素材替换控件包括影像素材替换控件、文字替换控件和音乐替换控件。在本公开实施例中充分考虑到用户可能为老人、信息技术水平不高的人群等特殊人群，在此不再提供复杂的剪辑功能，而是直接为用户提供素材替换功能，使用户可以直接替换视频模板中的素材。诸如，替换视频模板所使用的影响素材、文字素材及音乐素材中的一种或多种，不仅便于此类特殊人群理解和使用，而且基本满足此类特殊人群的视频剪辑需求。此外，上述方式仅通过展现几个基础的素材替换控件，在对用户进行剪辑引导提示的基础上，也可以使页面尽可能得以简化，避免相关技术中在一个剪辑页面上同时提供的复杂多功能剪辑信息给用户带来无从下手的感觉，更便于用户快速操作。
步骤S104，响应于用户在多个素材替换控件中选择目标替换控件，切换至目标替换控件对应的目标替换页面；其中，目标替换页面中展示有备选素材或内容输入区域。
在本公开实施例中，考虑到诸如老人等特殊人群对于高密度信息的处理能力通常较差，而相关技术中将所有剪辑功能的信息都呈现在同一个页面，使页面信息量较大且难以理解；为此，本公开实施例首先可以在剪辑页面清楚呈现几种基础的素材替换控件，并针对每种剪辑控件单独设置相应的剪辑页面，不同素材替换控件对应的替换页面不同，也即用户可以根据剪辑需求切入至所需的剪辑入口而有针对性地替换模板素材，通过不同的替换页面分别呈现不同信息，不仅可以有效降低剪辑页面上的信息量，而且也更便于诸如老人等特殊人群进行理解及操作。
步骤S106，获取用户在目标替换页面上选中的素材或内容输入区域中的内容作为更新素材，并采用更新素材替换目标视频模板中与更新素材对应的模板素材。
诸如，目标替换控件为音乐替换控件，目标替换页面上呈现有音乐列表，可将用户在目标替换页面上选择的音乐替换目标视频模板中的模板音乐；又诸如，目标替换控件为影像替换控件，目标替换页面上呈现有用户可选的影像素材，示例性地，影像素材可以是照片和/或视频等用户在本地相册存储的素材，可以将用户选择的照片和/或视频替换目标视频模板中的影像素材；又诸如，目标替换控件为文字替换控件，目标替换页面上呈现有内容输入区域，则可以将用户在内容输入区域中输入的文字替换目标视频模板中的文字。
步骤S108，将经素材替换后的目标视频模板中的素材按照剪辑操作序列进行剪辑，生成预览视频帧图像，并将预览视频帧图像展示在剪辑页面上。
可以理解的是，用户可以将目标视频模板中的所有素材均进行替换，也可以仅替换目标视频模板中的部分素材。因此，经素材替换后的目标视频模板中的素材可能均为用户的更新素材，也可能既包含部分模板素材又包含用户的更新素材。通过采用剪辑操作序列对经素材 替换后的目标视频模板中当前的素材进行剪辑，即可渲染得到预览视频帧图像以供用户预览。在实际应用中，可直接将预览视频帧图像替换模板视频帧图像展示在剪辑页面上，可以理解的是，预览视频帧图像可以有多张，多张预览视频帧图像按序播放，用户可以直观感受自己更换素材后的视频帧图像的呈现效果。如用户满意该效果并确认导出，此时便可基于预览视频帧图像生成目标视频，用户可根据需求保存目标视频或者将目标视频发布至指定平台。如用户不满意当前的预览视频帧图像的呈现效果，则仍旧可以采用剪辑页面上的多个素材替换控件继续替换素材，之后再次生成新的预览视频帧图像即可。通过上述方式，可以使用户在已选中的目标视频模板的基础上，无需进行复杂的剪辑操作，只需更换模板中的素材。本公开实施例可按照目标模板视频对应的剪辑操作序列对经素材替换后的目标视频模板中的素材进行自动剪辑，快速高效地达到与目标模板视频相应的剪辑效果，可极大节约用户的视频剪辑时间，提升视频剪辑效率。
综上，本公开实施例的上述技术方案所提供的视频剪辑流程简单易懂，导向性较强，可以较好地引导用户先后选择视频模板及通过素材替换控件选择所需的更新素材，并直接采用更新素材替换视频模板中与更新素材对应的模板素材，从而在此基础上快速生成预览视频帧图像。本公开实施例为用户提供了多个素材类别的素材替换控件，不同素材替换控件可对应不同的替换页面，也更便于用户理解及操作。通过对视频模板中的素材进行替换，可快速便捷地达到用户所需效果。综上，上述方式有效提升了诸如老年群体等人群的视频剪辑便捷性，较好地保障了用户体验。
在一些实施示例中，在响应于用户在多个视频模板中选择目标视频模板之前，可以参照如下步骤(1)和(2)执行：
(1)在第一展示页面上展示多个主题类别。在实际应用中，为了便于用户挑选模板，本公开实施例可以将多个视频模板划分为多个 主题类别。示例性地，主题类别诸如可以包括“和孩子一起”、“周末活动”、“户外郊游”“广场起舞”“下象棋”等，以便于用户可以根据主题类别快速选取符合当前素材编辑需求的目标主题类别，从而高效找到与目标主题类别匹配的视频模板。在第一展示页面上的主题类别的表现形式不进行限制。诸如，可以只采用文字标签的形式体现各主题类别，也可以采用图文形式体现各主题类别。
在一些具体的实施示例中，可以在第一展示页面上展示多张主题类别封面图；其中，主题类别封面图标注有主题类别名称。诸如，针对“广场起舞”主题类别配置的封面图为广场跳舞的图像，针对“和孩子在一起”的主题类别配置的封面图为老人与孩子相伴的图像，通过主题类别封面图，可以使用户直观便捷地了解到主题类别信息。为便于理解，可以参见图2所示的一种第一展示页面示意图，示意出了主题类别封面图，以及主题类别封面图下方标注的主题类别名称。此外，还可以进一步标注主题类别的最近更新时间等其它信息，在此不进行限制。通过上述方式，用户可以清楚直观地查看当前可选的主题类别，用户可以通过诸如手指上滑等操作切换当前展示页面上展示的主题类别，从而浏览更多的主题类别并从中选择所需的目标主题类别。考虑到用户是老人等特殊群体，示例性地，第一展示页面上同时出现的主题类别封面图不超过预设数量，或者，主题类别封面图与第一展示页面的尺寸占比大于预设阈值，以便用户可以清楚地观看较大的封面图。
(2)响应于用户在多个主题类别中选择目标主题类别，在第二展示页面上展示目标主题类别下的视频模板。
在实际应用中，可以将用户点击的主题类别作为用户选择的目标主题类别，并在用户选择目标主题类别之后，可以从第一展示页面切换至第二展示页面，以展示属于目标主题类别的多个视频模板供用户选择。在一些实施示例中，可以在第二展示页面中展示一个或多个目 标主题类别下的视频模板，在实际应用中，可以在第二展示页面中展示该视频模板的画面内容，具体实现时，该画面内容可以采用代表图的形式表征，也可以采用该视频模板的效果视频的形式表征，也即，第二展示页面可以直接为用户展示模板代表图，也可以为用户展示模板的效果视频，以供用户清楚了解模板的呈现效果。用户可以通过诸如手指左右滑动或上下滑动等方式切换第二展示页面上展示的视频模板，为便于用户清楚查看视频模板，第二展示页面上展示的视频模板的数量应不高于预设数量阈值。在一些具体的实施示例中，可以在第二展示页面上展示目标主题类别下的多个视频模板中的一个视频模板的画面内容；然后响应于用户的模板切换操作，基于目标主题类别下的多个视频模板的预设排序，在第二展示页面上展示切换后的视频模板的画面内容。通过上述示例，用户可以每次只看一个视频模板的画面内容，更为清楚直观，避免多个视频模板的画面内容同时显示在第二展示页面而导致观看的不便性。倘若不符合需求，用户可通过视频切换操作来更换在第二展示页面上展示的视频模板，直至找到符合需求的目标视频模板。为便于理解，可以参照如图3所示的一种第二展示页面示意图，在第二展示页面上只展示一个视频模板(假设为视频模板n)，用户可以通过向左或者向右滑动手指的方式切换视频模板n-1或视频模板n+1，以此清楚浏览各视频模板。
在用户选择了目标视频模板之后，可以直接进入剪辑页面，参见图4所示的一种剪辑页面示意图，在剪辑页面上示意出了视频帧展示区域以及多个素材类别的素材替换控件。在图4中，多个素材类别的素材替换控件分别为影像素材替换控件、文字替换控件和音乐替换控件，并分别以“换照片”、“加文字”、“换音乐”来标识控件，更简单易懂。这三类替换控件可以满足诸如老年群体、信息技术水平不高的群体等用户群体的绝大多数视频剪辑需求，更便于用户理解和操作。倘若用户是选择目标视频模板后进入剪辑页面，在剪辑页面上的视频 帧展示区域首先展示的是目标视频模板对应的模板视频帧图像，该展示区域可以播放模板视频帧图像，从而为用户展示模板的视频呈现效果。且素材替换控件可以浮设在视频帧展示区域上，不仅方便用户在感知模板视频呈现效果的基础上以及在多个素材替换控件的引导下，确定所需更换的素材类别，从而触发相应的素材替换控件，而且上述剪辑页面的设置方式更为简洁，视频帧展示区域相对于剪辑页面的占比大于预设阈值。诸如可以近乎全屏展示，从而可以使老年用户等视力不佳的群体清楚感受视频画面效果，多个素材替换控件浮设在视频帧展示区域上，不会额外占用页面面积，也即不会缩减视频帧展示区域的面积，从而可以充分确保视频画面大屏展示，保障用户具有良好观感。
在本公开实施例中，可以设置不同的素材替换控件，使用户能够切入至不同的素材替换页面执行素材替换操作，不仅便于用户理解和操作，也可以有效降低信息密度。以下针对每种素材类别对应的素材替换控件被触发后所展示的替换页面分别进行阐述说明。
在用户触发的目标替换控件包括影像素材替换控件的情况下，目标替换页面上按照预设的分类维度展示有分类后的影像素材，影像素材包括照片和视频。也即，为了进一步便于用户选择所需的素材，本公开实施例在展示供用户选择的影像素材时，可以按照预设的分类维度对用户的影像素材进行分类，并将分类后的影像素材展示给用户。示例性地，分类维度包括时间维度、地点维度、主题维度中的一种或多种。与相关技术中直接将用户相册中的所有照片/视频等素材展示给用户相比，本公开实施例可以首先将用户可选的影像素材按照预设的分类维度进行分类，这种方式更便于用户根据需求快速选择所需编辑的照片。考虑到大多数用户在进行素材编辑时，都会采用具有共性的影像素材，诸如，采用一天内拍摄所得的影像素材，或者采用同一地点拍摄所得的影像素材，或者采用具有同一主题的影像素材，该主题 诸如为人物主题、山水主题等。因此，通过按照预设的分类维度将用户的影像素材进行分类，更符合用户的创作习惯，便于用户快速选择所需的影像素材。而且，通过上述分类方式对影像素材进行分类模块化处理，也能够为用户的浏览行为明确范围，以此降低信息过载给用户带来的无从下手的感受，提升用户的素材选择效率。
以分类维度是时间维度为例，可参照如图5所示的一种目标替换页面示意图，该目标替换页面即为影像素材选择页面，通过今天、昨天等时间维度进行影像素材归类，更便于用户选择，且也较好地符合用户的创作习惯。应当说明的是，图5仅为示例性说明，简单示意出“今天”“昨天”等时间维度，实际应用中还可以通过“一天前”、“三天前”“上周末”等方式进行时间维度归类，或者直接通过X月X日等日期方式进行时间维度归类。此外，在实际应用中，每个类别下的影像素材还可支持一键勾选，进一步提升用户选择影像素材的便利性。在实际应用中，用户还可以对目标替换页面中展示的影像素材进行缩放，诸如，通过双指操作即可实现素材的放大或缩小，用户可以根据需求设置目标替换页面中展示的影像素材大小，在此不进行限制。
为了便于用户清楚获知已选用的影像素材，上述方法还包括：在目标替换页面上按照指定方式标识用户在影像素材中选中的素材(以下简称为目标影像素材)；指定方式包括以下中的一种或多种：高亮方式、数字标记方式、槽位填充方式。其中，高亮方式包括将目标影像素材进行高亮处理，以区分其它影像素材；数字标记方式包括在目标影像素材处进行数字标记，以表明用户已选择该素材，且该素材是当前已选的第几个素材。槽位填充方式包括：在素材选择页面的下端设置多个槽位，槽位数量与目标视频模板所采用的素材数量相匹配。为便于理解，可以参见图6所示的一种目标影像素材的标识示意图，同时示意出高亮方式(素材1)以及槽位填充方式，具体的，倘若选 择的了素材1作为目标原始素材，则自动将素材1的图像填充在槽位1中。通过上述方式，用户可以一目了然地获知已选择的素材，更有利于用户执行素材选择操作，而且所见即所得，可以使用户在点选素材中构筑“片段连接”的使用概念。
考虑到诸如老人等部分人群不擅长使用拼音输入法进行拼写，一方面由于方言或发音不标准等原因，可能存在拼写错误等问题，另一方面由于拼音输入法为用户提供的键盘通常较小，不便于用户操作，因此在目标替换控件包括文字替换控件的情况下，目标替换页面上展示有供用户手写输入文字的内容输入区域，用户可以直接通过手写方式输入文字，更为方便快捷。在目标替换控件包括音乐替换控件的情况下，目标替换页面上可以展示有可滑动的候选音乐列表，且候选音乐列表在目标替换页面上同时展示的候选音乐的数量不高于预设数量阈值，诸如，每次仅展示4个候选音乐，相比于将更多的候选音乐都同时密集展示在页面上而言，本公开实施例提供的上述方式可有效降低信息密度，且通过限制同时展示的候选音乐数量，更便于老人用户等特殊群体进行选择。
综上，通过为不同的素材类别设置不同的替换控件以及不同的替换页面，可有效降低页面信息密度，更便于用户理解和操作。用户可以灵活编辑地替换模板中的素材，从而在模板基础上采用自己替换的素材快速高效地生成自己所需的视频。在具体实现时，可以将经素材替换后的目标视频模板中的素材按照剪辑操作序列进行剪辑，生成预览视频帧图像，并将预览视频帧图像展示在剪辑页面上。如图7所示的一种剪辑页面示意图，与图4不同之处在于，图7中的视频帧图像展示区域展示的内容为预览视频帧图像，以供用户预览基于目标视频模板进行剪辑后的视频效果。用户可以在此基础上再次更换照片、音乐或文字，也可以在确认后直接去分享。
为了使用户清楚观看到视频帧画面，剪辑页面中的视频帧展示区域相对于剪辑页面的占比大于预设阈值，视频帧展示区域用于展示模板视频帧图像或预览视频帧图像；且多个素材替换控件浮设在视频帧展示区域上。通过这种方式，可以较好地避免在视频帧画面之外的区域设置替换控件而导致视频帧画面较小，不便于观看的问题。示例性地，视频帧画面相对于剪辑页面的占比接近1，也即以全屏形式播放，更便于老人等特殊群体观看，有效保障用户的观看体验。另外，考虑到剪辑页面中倘若堆砌多功能信息，容易给用户带来剪辑压力感，且用户可能会无从下手，上述方式仅通过展现几个基础的素材替换控件，在对用户进行必要的剪辑引导提示的基础上，也可以使页面尽可能得以简化，也更便于用户操作。
进一步，本公开实施例可以响应于接收到用户针对预览视频帧图像的确认指令，将预览视频帧图像合成目标视频，以便于用户保存或者将目标视频分享至指定平台。
综上所述，本公开实施例提供的视频剪辑方法，首先提供了更为简单便捷的视频剪辑路径，简单易懂，导向性较强，可以较好地引导用户先后选择视频模板及通过素材替换控件选择所需的更新素材，并直接采用更新素材替换视频模板中与更新素材对应的模板素材，从而在此基础上快速生成预览视频帧图像。本公开实施例为用户提供了多个素材类别的素材替换控件，不同素材替换控件可对应不同的替换页面，上述方式通过拆分功能层级、降噪等方式分层呈现信息，降低每个页面的信息密度，增强重点信息有效性，更便于用户理解和操作。上述方式有效提升了诸如老年群体等人群的视频剪辑便捷性，缩短用户的创作思考时间，较好地保障了用户体验。
本公开实施例对上述视频剪辑方法的应用场景不进行限制，诸如，可以单独针对老人提供采用上述视频剪辑方法的软件应用，又诸 如，也可以在已有的视频剪辑软件的基础上，开设老人模式等特殊模式，在该模式处于开启状态的情况下，再执行上述视频剪辑方法。
