1. A video retrieval method, performed by a computer device, the method comprising:
receiving a search request from a terminal device, the search request including a query video submitted by a user through a video retrieval interface;
performing feature extraction on the query video using a target image processing sub-model of a trained target video retrieval model to obtain a corresponding image feature of the query video;
performing feature extraction on the image feature using a target quantization processing sub-model of the target video retrieval model to obtain a corresponding first quantization feature;
identifying, from first candidate videos, at least one second candidate video whose associated category similarity to the query video meets a set category similarity requirement based on the first quantization feature;
identifying, among the at least one second candidate video, a target video whose associated content similarity to the query video meets a set content similarity requirement, further including:
determining a ratio between a total matching duration and a comparison duration as a content repetition degree between the query video and one second candidate video;
determining that a content similarity between the query video and the one second candidate video meets the set content similarity requirement when the content repetition degree exceeds a set content repetition degree threshold value; and
identifying the one second candidate video as the target video; and
returning the target video to the terminal device, wherein the target video is configured to be presented on the video retrieval interface and a progress bar of the target video includes at least one segment that is deemed to be similar to the query video and marked visually different from the rest of the target video.
