US Patent 10468065 Video frame difference engine

An embodiment detects where frames within a video have been added, deleted, or changed. The embodiment tracks the modifications through subsequent versions of the source video, and retains various metadata (corresponding to the individual edits) that describes the context and specifics of the edits. In an embodiment only changes to the original video need be tracked by preserving only those clips that have been added, removed, or changed. This ability enables a video editor to maintain the various changes made to a video and see the history of changes while alleviating much of the file storage associated with large, high-quality videos. Other embodiments are described herein.
