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.
