Systems and methods for associating metadata with scenes in a video
Abstract:
Systems and methods for associating metadata with scene changes are described. At least one embodiment includes a system for associating metadata with a video. The system comprises an input module for reading a first video, wherein the input module is configured to receive special effects specified by a user and an insertion point in which to insert the special effects. The system further comprises a key frame module for identifying at least one key frame preceding the specified insertion point, the key frame comprising at least one of a scene change and a particular scene identified by the user. The system also includes a metadata module for calculating time differences between the insertion point and the one or more key frames, the metadata module further configured to store the special effects input by the user, the insertion point, the time differences, and key frames as metadata.In accordance with some embodiments, the system further comprises an insertion module for reading a second video and inserting the special effects specified for the first video into the second video, where the insertion module is further configured to read the stored metadata and identify a matching key frame within the second video. The insertion module is further configured to add the time difference associated with the key frame stored within the metadata to the matching key frame to determine an insertion point for the second video and add the special effects at the insertion point for the second video.
