小学生英语演讲背景加抠图制作教程

小鸟爱蓝天，鱼儿爱跳海，今天我们来做这个，看教程小，先用手机对着大白墙，像这样拍一段视频。注意我们在录制的时候光源一定要充足， 光线不够充足，可以摆两盏补光灯，像这样摆放，左右各一个。打开剪映，点击开始创作。点击素材库，搜索红色背景素材，找到合适的背景素材，添加即可。点击画中画，新增画中画，导入拍摄好的视频， 此时我们的化妆化视频与主轨道视频时常不一致。点击主轨道视频点变速，常规变速，将视频变速至零点一倍。 点击画中画，点抠像，点智能抠像，将人物抠出，这样就可以去除白启航的背景，双指将人物放大，放在合适的位置，点击调节，如果人物 偏暗，可以把亮度提高一点点。点击音频，选择音乐，选择一个适合的音乐，点击分割，我们将前奏没有音乐的部分把它删除。此时录制视频比背景视频背景音乐长，我们将多出的部分分割删除。 注意，我们刚才操作的抠图一定要等到显示抠图成功，最后再点导出片头片尾的制作可参考我的上期视频哦，下期见！
