为了更清楚地说明本公开实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,对于本领域普通技术人员而言,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

图2为本公开实施例提供的一种视频处理界面的示意图;

图4为本公开实施例提供的一种效果应用的预览设备结构示意图。
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。
随着用户对视频处理的要求越来越高,针对视频处理的交互功能也越来越多样化,例如,在将某种效果样式真正的应用到视频之前,可以先将该效果样式应用到视频,并对视频的实际画面效果进行预览,以帮助用户做出更满意的选择,进而提升用户使用体验。
目前,将效果样式应用到视频的预览功能,仅支持将选中的效果样式作用于某一帧视频画面的效果预览,而无法为用户提供将效果样式应用于视频片段的完整预览效果,不利于用户在对视频进行效果处理时做出准确的选择,降低了用户的使用体验。
为此,本公开提供了一种效果应用的预览方法,具体的,在接收到针对目标效果样式的预览触发操作时,以视频轨道上指针的位置作为起始点,为目标效果样式生成虚拟视频帧。然后,基于时间轴同步播放该虚拟视频帧以及视频轨道上与该虚拟视频帧对应的视频片段,以实现对目标效果样式应用于该视频片段的效果的预览。本公开通过为目标效果样式生成虚拟视频帧,并与视频片段同步播放的方式,实现对将目标效果样式应用到视频片段的完整画面效果的预览,提供更真实的预览效果,帮助用户在对视频进行效果处理时做出更满意的选择,从而提升用户的使用体验。
基于此,本公开实施例提供了一种效果应用的预览方法,参考图1,为本公开实施例提供的一种效果应用的预览方法的流程图,该方法包括:
S101:响应于针对目标效果样式的预览触发操作,以视频轨道上指针的位置作为起始点,为所述目标效果样式生成虚拟视频帧。
本公开实施例中,目标效果样式可以是被选中的任一种效果样式,其中,可以包括动画类型效果样式和静态类型效果样式,具体的,动画类型效果样式可以包括特效、动态贴纸、动态文字等效果样式,静态类型效果样式可以包括滤镜、静态特效、静态贴纸、静态文字等效果样式。
实际应用中,在触发预览功能之前,首先确定效果样式的作用位置,具 体是指将选中的效果样式应用于视频的哪个片段。本公开实施例可以通过视频轨道上的指针确定效果样式的作用位置。
参考图2,为本公开实施例提供的一种视频处理界面的示意图,其中,用户可以通过移动视频轨道上指针的位置,确定效果样式的作用位置。在确定视频轨道上指针的位置之后,通过点击界面上展示的多种效果样式的至少一种效果样式,确定目标效果样式,同时触发将该目标效果样式应用到指针的位置的预览操作。
一种可选的实施方式中,在确定目标效果样式和视频轨道上指针的位置之后,可以通过预设的预览按钮触发将目标效果样式应用到指针的位置的预览操作。
本公开实施例中,在接收到针对目标效果样式的预览触发操作后,以视频轨道上指针的位置作为起始点,为目标效果样式生成虚拟视频帧。如图2所示,在音频轨道上紧贴指针的右边位置,为目标效果样式生成虚拟视频帧,又称为虚帧。
一种可选的实施方式中,虚拟视频帧对应的长度可以与目标效果样式的显示持续时间相同,例如,动画类型效果样式通常具有显示持续时间参数,如显示持续时间为1秒的某个动画效果,此时虚拟视频帧是以视频轨道上指针的位置为起始点,以目标效果样式的显示持续时间为长度的连续帧。
另一种可选的实施方式中,虚拟视频帧对应的长度可以与起始点到预设结束点的长度相同。其中,在触发预览操作之前,预先确定与指针定位的起始点相对应的结束点,作为虚拟视频帧的结束点。当接收到针对目标效果样式的预览触发操作时,在由指针定位的起始点和预设结束点之间,为目标效果样式生成虚拟视频帧。
实际应用中,对于静态类型效果样式,虚拟视频帧对应的长度通常基于起始点到预设结束点的长度确定,例如虚拟视频帧对应的长度与起始点到预设结束点的长度相同;而对于动画类型效果样式可以采用上述任意一种方式确定虚拟视频帧对应的长度。
一种可选的实施方式中,本公开实施例在接收到针对目标效果样式的预览触发操作时,不仅为目标效果样式生成虚拟视频帧,同时还可以在视频播放窗口中正在播放的视频画面上显示目标效果样式,通过将目标效果样式静态的应用于指针定位的视频画面的预览效果,为用户提供初步的预览感受。 如图2所示,在视频处理界面的右上方的视频播放窗口中的视频画面上静态显示有目标效果样式。
另外,视频可以包括多个视频轨道,如主轨道、画中画轨道等,为了体现目标效果样式与各个视频轨道上的视频画面之间的层级关系,本公开实施例可以通过确定虚拟轨道与各个视频轨道之间的层级关系,以及在虚拟轨道上为目标效果样式生成虚拟视频帧的方式,体现目标效果样式与各个视频轨道上的视频画面之间的层级关系。
如图2所示,虚拟视频帧对应的虚拟轨道位于画中画轨道和主轨道的上层,明确体现出了虚拟轨道上的目标效果样式与各个视频轨道上视频画面的层级关系,例如,虚拟轨道位于第一层级,画中画轨道位于第二层级,主轨道位于第三层级,第一层级会遮挡第二层级和第三层级的画面,第二层级会遮挡第三层级的画面。
S102:基于时间轴同步播放所述虚拟视频帧以及所述视频轨道上与所述虚拟视频帧对应的视频片段,以便对所述目标效果样式应用于所述视频片段的效果进行预览。
本公开实施例中,在生成虚拟视频帧之后,自动触发基于时间轴同步播放虚拟视频帧以及视频轨道上与虚拟视频帧对应的视频片段,通过对虚拟视频帧和该视频片段的同步播放,可以为用户提供将目标效果样式应用于该视频片段的整体效果预览。
实际应用中,在生成虚拟视频帧之后,确定与该虚拟视频帧对应的视频片段,其中,该视频片段包括与该虚拟视频帧具有相同时间信息的各个视频轨道上的视频帧。如图2所示,虚拟视频帧对应的视频片段包括起始点到结束点之间的各个视频轨道上的视频帧。
本公开提供的效果应用的预览方法中,在接收到针对目标效果样式的预览触发操作时,以视频轨道上指针的位置作为起始点,为目标效果样式生成虚拟视频帧。然后,基于时间轴同步播放该虚拟视频帧以及视频轨道上与该虚拟视频帧对应的视频片段,以实现对目标效果样式应用于该视频片段的效果的预览。本公开实施例通过为目标效果样式生成虚拟视频帧,并与视频片段同步播放的方式,实现对将目标效果样式应用到视频片段的完整画面效果的预览,提供更真实的预览效果,帮助用户在对视频进行效果处理时做出更满意的选择,从而提升用户的使用体验。
与上述方法实施例属于同一个发明构思,本公开实施例还提供了一种效果应用的预览装置,参考图3,为本公开实施例提供的一种效果应用的预览装置结构示意图,所述装置包括:
