Referring to fig. 2, a video processing terminal includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor executes the computer program to implement the steps of the video processing method in the first embodiment, the second embodiment, or the third embodiment.

To sum up, in the video recording process, the video processing method and the terminal provided by the invention acquire the audio data of the video in real time, when the audio data is judged to have the preset voice tag through voice recognition, the initial content information and the time point information corresponding to the preset voice tag are acquired, when the initial content information has no preset ending mark in the preset time from the time point information and the initial content information does not accord with the preset rule, a content information determining instruction is sent for a user to determine the content information, the modified content information is determined as the final content information, the video dotting accuracy is further improved, the user can directly input the preset voice tag and the corresponding description information through voice, the corresponding description information can be automatically acquired through voice recognition, and the preset voice tag and the description information can most intuitively describe the information required to be dotted in the video, the video dotting efficiency can be improved; determining a key frame corresponding to the time point information in the video according to the time point information, dotting the key frame according to a preset voice tag and final content information to generate a dotted video, directly forming key elements of the dotting information in the video recording process, and dotting the video in real time; the preset voice tag and the description information corresponding to the preset voice tag are stored in the preset video content search library, so that the efficiency of establishing the preset video content search library is improved; the method comprises the steps of determining retrieval results corresponding to retrieval keywords from a plurality of data tables according to the retrieval keywords, determining target preset voice tags, target final content information and target time point information corresponding to the retrieval results according to a preset video content retrieval library, and acquiring corresponding video clips from videos, so that the method is suitable for simple video content retrieval and complex video content retrieval, and efficient video content retrieval is realized; after the plurality of video clips are obtained through retrieval, the plurality of video clips are directly displayed according to a time sequence, the original video is not segmented or integrated, and the spliced videos are not stored, so that the dynamic splicing display of the videos is realized, the storage space is saved, and the accuracy of video processing is ensured while the video processing efficiency is improved.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
