1. A method for identifying a video, comprising:
acquiring a predetermined number of video frames from a video to be identified to obtain a video frame sequence;
importing the video frame sequence into a pre-trained video identification model to obtain a classification tag probability corresponding to the video frame sequence, wherein the classification tag probability is used to characterize a probability of identifying a corresponding tag category of the video to be identified; and
setting, in response to the classification tag probability being greater than or equal to a preset identification accuracy threshold, a video tag for the video to be identified according to the classification tag probability, or
increasing, in response to the classification tag probability being less than the threshold, the number of video frames in the video frame sequence and continuing to perform the process of importing,
wherein the video tag is used to identify a content category of the video to be identified.
