The embodiment of the invention discloses a video clipping method and device, a memory medium and a terminal. The method comprises the steps of obtaining to-be-classified images in videos; obtaining apreset classification model based on machine learning, wherein the preset classification model is obtained by training a plurality of image samples of known types and is used for carrying out targetcontent-based classification on the images; inputting the to-be-classified images into the preset classification model, and obtaining output results of the preset classification model; and classifyingthe to-be-classified images according to the output results, and clipping the videos according to classification results, thereby obtaining clipped videos. According to the embodiment of the invention, through adoption of the technical scheme, the image classification dimensions can be enriched, the classification accuracy can be improved, and the videos can be automatically clipped according tothe types.
