Abstract: Converting variable frame rate video to fixed frame rate video is described. A variable frame rate (VFR) video having source frames with varying frame durations is obtained. A fixed frame rate for the VFR video is determined. A mapping is generated which maps the source frames of the VFR video to a sequence of result frames of the fixed frame rate. To generate the mapping, a suitable source frame is chosen for each result frame using one or more mapping rules. After the mapping is generated, the mapping is adjusted to improve smoothness of motion of the VFR video by adding at least one skipped source frame to the mapping and removing at least one repeated source frame from the mapping. The VFR video is then converted into, or interpreted as, a fixed frame rate video having the determined fixed frame rate based on the adjusted mapping.

Abstract: Methods and apparatus provide for a media tagger that obtains a media project defined according to a native representation. The media project is made up of project objects and the native representation describes each project object's context within the media project. The media tagger receives an exportable media object, encoded according to an output format, which can include logical contributions from the project object(s). The media tagger tags the exportable media object and stores the exportable media object in a media catalogue. The media tagger acknowledges the selection of a desired output format to create a formatted media project based on the native representation of the media project. Upon validating that the exportable media object in the media catalogue can be used to build the formatted media project, the media tagger exports the exportable media object from the media catalogue.

Abstract: Audio data and visual data are processed by providing storage devices (211, 212) for storing digital samples which are then read in response to edit events defined by a timeline (352, 353). Active audio tracks are processed in real time and an event, such as a cross-fade, defined by a single track that requires two interacting tracks of material, is identified. The location of events within available tracks is re-arranged so as to reduce the total number of active tracks required during playback. In effect, events are transferred to blank regions of existing tracks, thereby allowing both of the interacting tracks of cross-fades to be read without requiring additional track capacity during playback. In this way, an event defined by two interacting tracks is processed without requiring additional processing capacity.
