Abstract: In a video capture system, a virtual lens is simulated when applying a crop or zoom effect to an input video. An input video frame is received from the input video that has a first field of view and an input lens distortion caused by a lens used to capture the input video frame. A selection of a sub-frame representing a portion of the input video frame is obtained that has a second field of view smaller than the first field of view. The sub-frame is processed to remap the input lens distortion to a desired lens distortion in the sub-frame. The processed sub-frame is the outputted.

Abstract: A browser efficiently extracts media from a video presented through a web application having a different domain from a media server providing the web application while complying with cross-origin resource restrictions. A video portion is selected, and a header portion of the video is identified. A truncated video portion, which includes the selected video portion and a video portion contiguous to the selected video portion, is loaded into memory. A truncated video file is generated including the truncated video portion and a truncated video header. The truncated video file is encoded as a video tag included in the web application, and the media corresponding to the selected video portion is extracted by transcoding the truncated video file in the video tag. A server may also extract the media by loading the truncated video portion, generating the truncated video file, and transcoding the truncated video file to obtain the media.

Abstract: A playback speed effect is applied to a video using a playback speed template. The playback speed template specifies playback speed ratios (i.e., ratios between playback duration and capture duration) at the highlight moment, at a template start time, and at a template end time. A video associated with a highlight tag indicating a highlight capture time of a highlight moment within the video is accessed. An input portion of the video including the highlight moment is identified. The duration of the input portion has a duration depending on the template start time and the template end time. A playback speed template is applied to the input portion. A modified video including a modified video portion is generated from the input portion of the video according to the applied playback speed template and is provided for subsequent playback.

Abstract translation: 使用播放速度模板将播放速度效果应用于视频。 播放速度模板在亮点时刻，模板开始时间和模板结束时间指定播放速度比（即播放持续时间和捕获持续时间之间的比率）。 访问与指示视频内的高亮时刻的高亮捕获时间的高亮标记相关联的视频。 识别包括高亮时刻的视频的输入部分。 输入部分的持续时间具有取决于模板开始时间和模板结束时间的持续时间。 播放速度模板应用于输入部分。 根据应用的播放速度模板，从视频的输入部分生成包括修改的视频部分的修改的视频，并提供用于随后的重放。
