Automated preview generation for video entertainment content

A computer-implemented method, comprising:

• extracting, from individual ones of a plurality of segments of a video for which a preview is to be generated automatically, a respective set of features, including at least a first emotion-related feature associated with analysis of visual content of a segment and a second emotion-related feature associated with analysis of audio content of the segment;
• selecting a subset of segments of the plurality of segments using at least some features of the respective sets of features and a collection of filtering criteria, wherein the collection of filtering criteria includes at least one emotion-based filtering criterion;
• assigning, to individual segments of the subset, respective weighted preview-suitability scores using a combination of metrics, wherein the combination of metrics includes a first metric of similarity between the individual segments and a plot summary of the video;
• and
• combining, using at least the respective weighted preview-suitability scores, at least some segments of the subset to generate a first proposed preview for the video.

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors:

• extract, from individual ones of a plurality of segments of a video for which a preview is to be generated automatically, a respective set of features, including at least a first emotion-related feature associated with analysis of visual content of a segment and a second emotion-related feature associated with analysis of audio content of the segment;
• select a subset of segments of the plurality of segments using at least some features of the respective sets of features and a collection of filtering criteria, wherein the collection of filtering criteria includes at least one emotion-based filtering criterion;
• assign, to individual segments of the subset, respective weighted preview-suitability scores using a combination of metrics, wherein the combination of metrics includes a first metric of similarity between the individual segments and a plot summary of the video;
• and
• combine, using at least the respective weighted preview-suitability scores, at least some segments of the subset to generate a first proposed preview for the video.
