Abstract
Automated, algorithmic quality control is performed for digital content converted from one form or format to another. Such conversion may be made of movies, television programs, feature films, advertisements, or any other content. The conversion process may be semi or fully automated, and may include a range of alterations, such as pulldown or frame rate conversions, size and/or resolution conversions, addition of content, deletion of content, and so forth. Actual content contained in pre-and post-converted frames is utilized, such as by image recognition techniques, as a base for the quality control routines. Audio data may also be considered. The quality control is fully or nearly fully automated with minimal manual involvement.
Claims18
A system comprising a controller configured to:
- convert a digital video content file comprising successive frames of video content from a first version at a first frame rate to a second version at a second frame rate that is different from the first frame rate;
- and
- perform an automated quality control process by:
- identifying a frame in the first version;
- determining a corresponding frame in the second version that corresponds to the frame in the first version;
- identifying at least one subsequent frame in the first version;
- determining a corresponding subsequent frame in the second version that corresponds to the at least one subsequent frame in the first version;
- and
- analyzing content of the frame in the first version and content of the corresponding frame in the second version to verify that the second version is properly converted by comparing at least one characteristic of the content of the frame in the first version to at least one characteristic of the content of the corresponding frame in the second version, and by comparing at least one characteristic of the at least one subsequent frame in the first version to at least one characteristic of the corresponding subsequent frame in the second version.
A tangible, non-transitory, machine-readable medium, comprising machine-readable instructions to:
- convert a digital video content file comprising successive frames of video content from a first version at a first frame rate to a second version at a second frame rate that is different from the first frame rate;
- and
- perform an automated quality control process by:
- identifying a frame in the first version;
- determining a corresponding frame in the second version that corresponds to the frame in the first version;
- identifying at least one subsequent frame in the first version;
- determining a corresponding subsequent frame in the second version that corresponds to the at least one subsequent frame in the first version;
- and
- analyzing content of the frame in the first version and content of the corresponding frame in the second version to verify that the second version is properly converted by comparing at least one characteristic of the content of the frame in the first version to at least one characteristic of the content of the corresponding frame in the second version, and by comparing at least one characteristic of the at least one subsequent frame in the first version to at least one characteristic of the corresponding subsequent frame in the second version.
