Abstract The task of video captioning is to generate a video description corresponding to the video content, so there are stringent requirements for the extraction of fine-grained video features and the language processing of tag text. A new method using global control of the text and local strengthening during training is proposed in this paper. In this method, the context can be referred to when the training generates text. In addition, more attention is given to important words in the text, such as nouns and predicate verbs, and this approach greatly improves the recognition of objects and provides more accurate prediction of actions in the video. Moreover, in this paper, the authors adopt 2D and 3D multimodal feature extraction for the process of video feature extraction. Better results are achieved by the fine-grained feature capture of global attention and the fusion of bidirectional time flow. The method in this paper obtains good results on both the MSR-VTT and MSVD datasets.
