Method and system for matching clips with videos via media analysis

A device for processing a video file with overland text and a textless video file without overlaid text comprising a plurality of textless video clips, wherein the textless video clips are derived from the video file, the device comprising:

• a matching module for comparing each textless video clip to a plurality of portions of the video file, the plurality of portions corresponding to a full length video file, the matching module configured to:
• determine each textless video clip having a video portion image being similar to only a video portion image of only one portion of the video file as being an unambiguous match;
• determine each textless video clip having a video portion image being similar to only a video portion image of only one portion of the video file as being an unambiguous match,
• create a matched pair for each textless video clip and portion of the video file which is an unambiguous match;
• and
• create a potential matched pair for each textless video clip and each portion of the video file which is an ambiguous match,
• a training module configured to:
• compare, for each matched pair, a text content of the textless video clip and the portion of the video file;
• identify, for each matched pair, if the compared text content is different;
• determine, if the text content is different, that the textless video clip corresponds to a portion of the video file having overlaid text;
• and
• training a classifier to predict whether an area of text detected in the full length video is overlaid text in dependence on this identification and determination;
• a processing module configured to:
• determine a probability of each portion of the full length video having overlaid text via the trained classifier;
• resolve the potential matched pairs with the determined probability as being matched pairs.
