Abstract

Systems and methods are provided for transcoding media content in accordance with thematic and/or cinematic characteristics of scenes. In particular, compression techniques may be selected to optimize compression of scenes based on their thematic and/cinematic characteristics. Scene boundary identifiers, such as scene in and out points may be identified, and the corresponding thematic and/or cinematic characteristic meta-data can be sent to a transcoder for transcoding. In this way, the specific characteristics of each scene in a movie can be accounted for during transcoding. This can result in transcoded versions of the movie that have better audio/visual qualities, and that can be encoded at a lower overall bit rate.

Background

TECHNICAL FIELD

The present disclosure relates generally to digital media encoding, and more particularly, some embodiments relate to systems and methods for optimizing compression techniques based on a type of scene being transcoded.DESCRIPTION OF THE RELATED ART

Due to the growing number of digital media distribution platforms that are available, a single piece of media content, such as a movie, is often digitized or transcoded into different formats and/or bit-rates. Many content distributors create multiple versions of a single video, song, or other digital media program for multiple avenues of distribution. For example, for a single piece of content, a video distributor might maintain a plurality of different files having the same resolution but different bitrates. These groups of files may be used in web distribution using adaptive variable bitrate streaming techniques.

Transcoding can be controlled with settings that specify or configure the manner in which compression is performed to achieve a desired output file, which may be used, for example, in adaptive variable bitrate streaming distribution. The settings are often selected based on the type of media content being transcoded, for example, whether the media content is 3D animated media content, hand drawn animated media content, media content characterized by film grain, etc. In other words, the settings are selected based on a characterization of an entire instance of media content, e.g., an ent

Claims

1. A computer-implemented method, comprising: identifying and categorizing scenes of a media content; assigning a compression profile to each of the scenes, wherein the compression profile is selected based upon one or more characteristics of at least one of the scenes; transcoding each of the scenes of the media content from a first format to at least one other format in accordance with the assigned compression profiles, each of the assigned compression profiles comprising a video bitrate and output frame size; generating an output file from the transcoded media content in the at least one other format, the output file comprising transcoded versions of each of the scenes commensurate with the assigned compression profiles. | 13. A computer-implemented method, comprising: receiving scene start and end points associated with each of a plurality of scenes comprising a movie; receiving one or more sets of compression settings applicable to each of the plurality of scenes, each of the one or more sets of compression settings having been selected based upon at least one of thematic and cinematic characteristics of each of the plurality of scenes, and each of the one or more sets of compression settings comprising a video bitrate and output frame size optimized for the least one of the thematic and cinematic characteristics of each of the plurality of scenes; transcoding each of the plurality of scenes in accordance with a corresponding set of compression settings; and outputting transcoded versions of each of the plurality of scenes. | 18. A system, comprising: a controller adapted to: obtain sets of groups of pictures each set of the groups of pictures representing one of a plurality of scenes of a media content; assign one or more compression profiles including one or more compression techniques to each of the plurality of scenes, each of the one or more compression techniques having been selected based upon at least one of thematic and cinematic characteristics of each of the plurality of scenes to produce a video bitrate and output frame size optimized for the least one of the thematic and cinematic characteristics of each of the plurality of scenes; and at least one transcoder adapted to: transcode each of the plurality of scenes using a corresponding compression profile; and output a transcoded version of the media content comprising the plurality of transcoded scenes. | 22. A computer-implemented method, comprising: identifying and categorizing scenes of media content; assigning a compression profile to each of the scenes, wherein the compression profile is selected based upon one or more characteristics of at least one of the scenes, a first scene of at least one of the scenes comprising live stream or live broadcast media content; transcoding the first scene from a first format to at least one other format in accordance with the compression profile, the compression profile specifying a single-pass, constant bit rate compression scheme; generating an output file from the transcoded media content in the at least one other format.
