下面结合附图，通过具体地实施例及其应用场景对本申请实施例提供的视频录制方法进行详细地说明。
请参见图1，本申请实施例提供一种视频录制方法，该视频录制方法应用于电子设备。如图1所示，方法包括如下步骤101至步骤103。
步骤101、在电子设备显示视频录制预览界面且接收到第一输入的情况下，响应于第一输入，开启视频录制模式，并获取目标曲线目标曲线上每一坐标点包括时间点和变焦倍数。
步骤102、在开启视频录制模式后的第一时间点，以第一变焦倍数拍摄第一图片，第一变焦倍数为目标曲线中在第一时间点的变焦倍数。
步骤103、将第一图片作为录制视频的帧图片。
这里，在电子设备开启视频录制模式的情况下，电子设备可以通过目标曲线上每一坐标点中时间点和变焦倍数，确定视频录制过程中任一时间点的变焦倍数，即当前录制的时间点(即第一时间点)的变焦倍数(即第一变焦倍数)为其所在坐标点中的变焦倍数，从而可以实现根据目标曲线调节视频录制过程中的变焦倍数，如此，通过本申请实施例，实现视频录制过程中对变焦倍数的调节，无需用户的输入来调节变焦倍数，从而可以避免因用户的输入引起的录制视频中画面的抖动，进而提升录制的视频质量。
在上述步骤101中，在电子设备显示有视频录制预览界面的情况下，电子设备可以接收到用户在视频录制预览界面的第一输入，并响应于该第一输入，开启视频录制模式，以及获取目标曲线。
本申请实施例中，上述电子设备显示视频录制预览界面，可以是电子设备在接收到用于指示显示视频录制预览界面的输入的情况下，响应于该输入显示上述视频录制预览界面。
其中，上述用于指示显示视频录制预览界面的输入，可以是语音输入、隔空手势输入和触控输入等中的至少一种。
例如，可以是电子设备接收到用户点击相机应用程序的图标的触控输入，响应于该触控输入显示视频录制预览界面，如图2所示。
另外，上述第一输入可以是任意用于指示开启视频录制模式的输入，其也可以是语音输入、隔空手势输入和触控输入等中的至少一种。
例如，如图3所示，若电子设备接收到用户在视频拍摄预览界面中的视频录制按钮31上的点击输入(即第一输入)，则电子设备开启视频录制模式。
需要说明的是，上述电子设备开启视频录制模式，可以理解为电子设备以开启视频录制模式的时间点为起始时间，随着时间的推进拍摄起始时间以及起始时间之后的每一帧图像，并通过拍摄的所有帧图像生成录制视频，即录制视频由拍摄的所有帧图像组成。
本申请实施例中，电子设备在接收到上述第一输入开启视频录制模式时，还可以响应于该第一输入获取上述目标曲线。
其中，上述电子设备获取上述目标曲线，可以是电子设备中预先设定有至少一条曲线，电子设备可以响应于上述第一输入，在上述至少一条曲线中确定一条曲线为上述目标曲线。
需要说明的是，上述在至少一条曲线中确定一条曲线为上述目标曲线，可以是电子设备将用户的输入所指示的曲线确定为上述目标曲线。
例如，如图3所示，在电子设备接收到用户在视频拍摄预览界面中的视频录制按钮31上的点击输入的情况下，电子设备在视频拍摄预览界面中显示悬浮框，该悬浮框中显示有至少一条曲线。在电子设备接收到对该至少一条曲线中曲线1的点击输入的情况下，电子设备将曲线1确定为上述目标曲线。
或者，为减少用户在视频录制过程中的操作，电子设备可以自动在上述至少一条曲线中确定一条曲线作为上述目标曲线。具体地，上述获取目标曲线，可以包括：
获取电子设备的场景信息；
确定多条曲线中与场景信息匹配的曲线为目标曲线。
这里，电子设备可以根据其场景信息，在多条曲线中确定与场景信息相匹配的目标曲线，从而不仅可以使选取的目标曲线能够与电子设备录制视频的场景适配，还可以减少用户的输入，提升视频录制的操作便捷性。
其中，上述场景信息可以是任何与电子设备当前录制视频所处的场景相关联的信息，例如，上述场景信息可以包括位置、时间、声音以及环境参数等中的至少一项。
例如，在用户使用电子设备录制舞蹈视频时，在电子设备接收到用户的第一输入并开启视频录制模式的情况下，电子设备可以获取开始视频录 制模式后的5秒内的音乐片段，根据获取到的音乐片段确定录制该舞蹈视频过程中播放的音频文件，并将至少一条曲线中与上述播放的音频文件存在对应关系的曲线确定为上述目标曲线。
当然，上述目标曲线也可以是在接收到上述第一输入之前生成的曲线，且该目标曲线的生成可以是电子设备根据用户的输入生成。
本申请实施例中，为满足用户的实际需求，上述目标曲线可以是由用户通过输入绘制的曲线。具体地，上述开启视频录制，并获取目标曲线之前，上述方法还可以包括：
在视频录制预览界面接收到第二输入的情况下，响应于第二输入，显示曲线绘制界面；
在接收到在曲线绘制界面输入的第三输入的情况下，在曲线绘制界面中显示第三输入所绘制的目标曲线。
这里，电子设备可以根据用户在曲线绘制界面的输入，实现对上述目标曲线的绘制，从而使目标曲线的生成可以满足用户的实际需求。
其中，上述第二输入可以是任何用于指示电子设备显示曲线绘制界面的输入，其可以是语音输入、隔空手势输入以及触控输入中的至少一项。
例如，如图4所示，在电子设备显示视频录制预览界面的情况下，若电子设备接收到用户对视频录制预览界面中的按钮41的点击输入，则电子设备显示曲线绘制界面，如图5所示。
另外，上述曲线绘制界面可以是任意供用户输入上述第三输入的显示界面。例如，上述曲线绘制界面可以是显示时间-变焦倍数坐标系的显示界面，该时间-变焦倍数坐标系的横坐标为时间且纵坐标为变焦倍数。
本申请实施例中，在电子设备显示有上述曲线绘制界面的情况下，若电子设备接收到上述第三输入，电子设备可以生成第三输入所绘制的目标曲线并显示。
其中，上述第三输入可以是任意用于在上述曲线绘制界面中绘制曲线的输入。例如，上述第三输入可以是在曲线绘制界面中输入滑动轨迹为曲线的滑动输入，等等。
另外，上述电子设备可以根据第三输入生成上述目标曲线。例如，可 以是电子设备接收到用户在上述曲线绘制界面的时间-变焦倍数坐标系中输入的滑动输入，电子设备将该滑动输入的滑动轨迹在时间-变焦倍数坐标系中的曲线作为上述目标曲线。
或者，为使电子设备生成的目标曲线的精度更高且操作更便捷，上述显示曲线绘制界面之后，上述方法还可以包括：
在接收到在曲线绘制界面中的第四输入的情况下，响应于第四输入，开启曲线绘制模式，并在曲线绘制界面显示变焦倍数调节标识；
在曲线绘制界面中显示第三输入所绘制的目标曲线，可以包括：
在开启曲线绘制模式之后的第二时间点接收到第三输入的情况下，则生成第一坐标点，其中，第三输入包括：开启曲线绘制模式之后的任一时间点，在变焦倍数调节标识上调节变焦倍数的输入；第一坐标点包括第二时间点和第二变焦倍数，且第二变焦倍数为第三输入在第二时间点调节的变焦倍数；
将第一坐标点作为目标曲线上的坐标点，并显示目标曲线，目标曲线由开启曲线绘制模式至第二时间点的时间段内生成的坐标点组成。
这里，电子设备可以在开启曲线绘制模式之后，可以根据第三输入在变焦倍数调节标识上调节的每一时间点的变焦倍数，生成开启曲线绘制模式之后每一时间点对应的坐标点，并通过生成的坐标点形成上述目标曲线，从而用户在绘制目标曲线的过程中，仅需要根据时间的推进调节每一时间点的变焦倍数，使得用户的输入更便捷且可控，进而提升电子设备绘制目标曲线的便捷性以及绘制的目标曲线的精度。
其中，上述第四输入可以是任何用于指示开启上述曲线绘制模式的输入，其可以是语音输入、隔空手势输入以及触控输入等中的至少一项。
例如，如图5所示，在电子设备显示有曲线绘制界面的情况下，若电子设备接收到用户在曲线绘制界面中的按钮51的点击输入，则电子设备开启上述曲线绘制模式。
另外，上述变焦倍数调节标识可以是曲线绘制界面中显示的，且用于调节变焦倍数的任意标识。例如，上述变焦倍数调节标识可以是显示曲线绘制界面中的滑轨以及显示于滑轨上的滑块，用户通过拖动滑块沿滑轨滑 动，可以实现对变焦倍数的调节；或者，如图5所示，电子设备在其曲线绘制界面中显示箭头虚线52，若用户在沿箭头所指方向滑动距离越远，则调节的变焦倍数越大；反之，则调节的变焦倍数越小。
本申请实施例中，上述生成第一坐标点，可以是当上述电子设备开启曲线绘制模式时，电子设备开始计时，即将开启曲线绘制模式的时间点作为初始时间点(如为0)。随着时间的推进，电子设备可以根据当前时间点(即第二时间点)接收到的第三输入所调节的变焦倍数(即第二变焦倍数)，将当前时间点对应的坐标点(即第一坐标点)的变焦倍数确定为第三输入在当前时间点所调节的变焦倍数。
另外，电子设备在生成上述第一坐标点时，可以将第一坐标点作为目标曲线上的坐标点，从而生成由上述初始时间点至上述第二时间点的所有坐标点组成的目标曲线。
例如，如图6所示，电子设备在当前时间点接收到用户沿箭头虚线52方向上的滑动输入，并将滑动输入所调节的变焦倍数作为当前时间点对应的坐标点中的变焦倍数，从而随着时间的推进，电子设备可以在其曲线绘制界面中生成曲线61(即目标曲线)。
需要说明的是，在绘制上述目标曲线的过程中，由于电子设备的曲线绘制界面可以显示的曲线段的长度有限，故上述显示目标曲线，可以包括：在曲线绘制界面显示目标曲线的部分曲线。
例如，电子设备生成0～3s时间段内的目标曲线，而曲线绘制界面中仅能够显示时间长度为1.5s的曲线，故当电子设备在当前时间为开启曲线绘制模式之后的3s时生成目标曲线时，电子设备仅将目标曲线在1.5s～3s内生成的部分曲线显示于曲线绘制界面，而在如图6所示的0～1.5s内生成的部分曲线移出屏幕，如图7所示。
本申请实施例中，为提升视频录制过程中的操作便捷性，上述目标曲线也可以是在接收到上述第一输入之前根据用户指示自动生成的曲线。具体地，上述开启视频录制，并获取目标曲线之前，上述方法还可以包括：
在视频录制预览界面接收到第四输入的情况下，响应于第四输入，显示音频文件列表，音频文件列表包括至少一个音频文件的标识；
在接收到在音频文件列表中的第五输入的情况下，基于第一音频文件，生成目标曲线并显示，其中，第一音频文件为：第五输入在至少一个音频文件的标识中指示的标识所对应的音频文件。
这里，电子设备可以根据用户在音频文件列表中所选取的音频文件，生成上述目标曲线，在生成目标曲线过程中无需用户输入绘制曲线的操作，从而降低用户操作量，提升电子设备的操作便捷性以及目标曲线生成的效率。
其中，上述第四输入可以是任意用于指示显示上述音频文件列表的输入，其可以是语音输入、隔空手势输入和触控输入等中的至少一项。
例如，如图4所示，在电子设备显示视频录制预览界面的情况下，若电子设备接收到用户对视频录制预览界面中的按钮41的点击输入(即第四输入)，则电子设备显示上述音频文件列表1，且该音频文件列表1包括音频A的选项、音频B的选项、音频C的选项等，如图8所示。
另外，上述第五输入可以是任意用于在上述音频文件列表选择的音频文件的输入，其可以是语音输入、隔空手势输入和触控输入等中的至少一项。
例如，如图8所示，若电子设备接收到用户点击音频文件B的选项的点击输入(即第五输入)的情况，则电子设备将音频文件B确定为上述第一音频文件。
本申请实施例中，在电子设备确定上述第一音频文件之后，电子设备可以基于该第一音频文件，生成上述目标曲线并进行显示。
其中，上述基于第一音频文件，生成上述目标曲线，可以是电子设备获取第一音频文件的响度波形图，并基于第一音频文件的响度波形图生成上述目标曲线。这里，响度波形图中的波形代表音频文件播放时音乐的强弱程度，故可以设置越强的响度对应越大的变焦倍数，从而使录制的视频具有较强的震撼力。
需要说明的是，上述基于第一音频文件的响度波形图生成上述目标曲线，可以是直接将响度波形图中的波形的边沿曲线确定为上述目标曲线。
但是，由于音频文件的响度波形图中响度的变化可能过于频繁，这样 生成的目标曲线中的变焦倍数也会变化频繁，故为避免录制视频中变焦倍数的调节过于频繁，可以通过响度波形图生成较为平顺的曲线作为目标曲线。
具体地，上述基于第一音频文件，生成目标曲线并显示，可以包括：
获取第一音频文件的响度波形图；
基于响度波形图的包络，生成目标曲线并显示。
这里，电子设备可以基于第一音频文件的响度波形图的包络，生成目标曲线，从而使基于响度波形图生成的目标曲线较为平顺，可以降低录制视屏过程中变焦倍数的调节频繁度，进而提升录制视频的质量。
例如，如图9(a)所示，为电子设备获取到的音频B的响度波形图。电子设备可以取音频B的响度波形图的包络，产生如图9(b)所示的平顺的曲线91，并将曲线91确定为上述目标曲线。
本申请实施例中，在电子设备开启上述视频录制模式并获取到上述目标曲线之后，电子设备可以基于该目标曲线进行视频录制，即在开启视频录制模式之后的任一时间点，在目标曲线上获取与该时间点对应的坐标点的变焦倍数作为拍摄当前帧图像的变焦倍数(即第一变焦倍数)，从而实现对视频录制过程中变焦倍数的调节。
需要说明的是，在上述电子设备基于上述目标曲线进行视频录制的过程中，可以在视频录制界面中显示上述目标曲线，以及，还可以显示时间点指示标识，时间点指示标识用于指示目标曲线中当前时间点的位置。
例如，如图3所示，在电子设备开启视频录制模式以及获取到目标曲线之后，电子设备显示视频录制界面，如图10(a)所示，并在视频录制界面中半透明地显示曲线101(即目标曲线)以及用于时间点指示角标102(即时间点指示标识)，时间点指示角标102的初始位置为曲线101的起始时间点T0，此时变焦倍数为0.9倍。
随着时间的推进，时间点指示角标102沿平行于曲线101的时间轴的方向移动至位置1，且时间点指示角标102指示曲线101的时间点T1，此时变焦倍数为3.0倍，如图10(b)所示，时间点T1拍摄的人物的图像大于时间点T0拍摄的人物的图像。
再随着时间的推进，时间点指示角标102沿平行于曲线101的时间轴的方向移动至位置2，且时间点指示角标102指示曲线101的时间点T2，此时变焦倍数为1.5倍，如图10(c)所示，时间点T2拍摄的人物的图像小于时间点T1拍摄的人物的图像。
再随着时间的推进，时间点指示角标102沿平行于曲线101的时间轴的方向移动至位置3，且时间点指示角标102指示曲线101的时间点T3，此时变焦倍数为4.0倍，如图10(d)所示，时间点T3拍摄的人物的图像大于时间点T2拍摄的人物的图像。
另外，在上述电子设备开启上述视频录制模式，并获取到上述目标曲线时，电子设备可以将目标曲线上的任一时间点作为视频录制的起始时间点(即开启视频录制模式的时间点)，再次并不作限定。
本申请实施例中，在电子设备基于上述目标曲线录制视频的过程中，上述目标曲线可以是固定不变的。
当然，在视频录制的过程中，可能会出现用户需要调节目标曲线，以改变当前时间点之后的时间点对应的变焦倍数的情况，为满足用户对目标曲线的调节需求，上述获取目标曲线之后，上述方法还可以包括：
若接收到用于调整目标曲线中第一曲线段的第六输入，则将第一曲线段更新为第六输入所调整的第二曲线段。
其中，在第一时间点可以为第一曲线段的时间点的情况下，第一变焦倍数为第二曲线段在第一时间点的变焦倍数。
这里，电子设备可以根据用户的输入(即第六输入)对目标曲线中的部分曲线段进行调节，实现改变该部分曲线段中时间点对应的变焦倍数，从而可以满足用户的实际需求，提升用户体验效果。
需要说明的是，上述第六输入可以是任何用于调整上述目标曲线中的部分曲线段的输入，其可以是语音输入、隔空手势输入和触控输入等中的至少一项。
例如，如图11所示，在电子设备的视频录制界面中显示有上述曲线101的情况下，若电子设备接收到用户在位置111沿虚线箭头所指方向的滑动输入(即第六输入)，则电子设备调整位置111所在的曲线段(即第 一曲线段)，使得调整后的曲线101更新为曲线112，且曲线112包括位置111所在的曲线段经过调整后的曲线段(即第二曲线段)，如图12所示。
需要说明的是，本申请实施例提供的视频录制方法，执行主体可以为视频录制装置，或者该视频录制装置中的用于视频录制的方法的控制模块。本申请实施例中以视频录制装置执行视频录制方法为例，说明本申请实施例提供的视频录制装置。
