1. A method of retrieving a video moment in a video database of an electronic device, the method comprising:
receiving, by the electronic device, a search query from a user to find the video moment in at least one video from a plurality of videos in the video database;
extracting, by the electronic device, at least one semantic vector from the search query;
mapping, by the electronic device, the extracted at least one semantic vector with corresponding visual features moment vector in a pre-stored feature vector database;
determining, by the electronic device, at least one moment tag and at least one time stamp associated with the mapped visual moment vector; and
retrieving, by the electronic device, a video moment clip using the at least one moment tag and at least one time stamp from the video database, wherein the video moment clip corresponds to the video moment in the search query,
wherein the feature vector database is generated by the electronic device from the video database in an offline mode.
