Look-ahead for video segments

A computer program product comprising a computer readable storage medium having program code embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, and wherein the program code is readable and executable by a processor to perform a method comprising:

• receiving a pre-recorded video, wherein the pre-recorded video is directed to a main topic;
• partitioning the pre-recorded video into sub-topic segments, wherein each sub-topic segment is about a sub-topic of the main topic;
• identifying previous entities' responses while previous entities viewed precursory sub-topic segments from the pre-recorded video, wherein the precursory sub-topic segments were presented before an upcoming sub-topic segment;
• receiving a current entity's responses that occurred while a current entity viewed one or more of the precursory sub-topic segments from the pre-recorded video;
• comparing the current entity's responses to the previous entities' responses;
• and
• in response to the current entity's responses matching the previous entities' responses, overlaying an alert over the pre-recorded video advising the current entity that the upcoming sub-topic segment will be difficult to understand.

A computer system comprising one or more processors, one or more computer readable memories, and one or more computer readable non-transitory storage mediums, and program instructions stored on at least one of the one or more computer readable non-transitory storage mediums for execution by at least one of the one or more processors via at least one of the one or more computer readable memories, the stored program instructions executed to perform a method comprising:

• receiving a pre-recorded video, wherein the pre-recorded video is directed to a main topic;
• partitioning the pre-recorded video into sub-topic segments, wherein each sub-topic segment is about a sub-topic of the main topic;
• identifying previous entities' responses while previous entities viewed precursory sub-topic segments from the pre-recorded video, wherein the precursory sub-topic segments were presented before an upcoming sub-topic segment;
• receiving a current entity's responses that occurred while a current entity viewed one or more of the precursory sub-topic segments from the pre-recorded video;
• comparing the current entity's responses to the previous entities' responses;
• and
• in response to the current entity's responses matching the previous entities' responses, overlaying an alert over the pre-recorded video advising the current entity that the upcoming sub-topic segment will be difficult to understand.
