Dynamic split-frame preview of video editing effects

摘要

This disclosure relates to dynamic split-frame preview of video editing effects. An editing component determines a set of editing effects for the video, generates a copy of the video, applies the set of editing effects to the copy, and provides the video and the copy to a rendering component. The rendering component generates a mask based on a set of mask criteria, renders a split-frame composite video using the video and the edited video based at least in part on the mask, and provides playback of the split-frame composite video. The split-frame composite video provides a dynamic split-frame preview of video editing effects, wherein one frame includes the video, and another frame includes the edited copy of the video.
