The invention provides a video insertion method, a storage medium and a terminal, so as to solve the problem that the video insertion effect is poor in the prior art. The method comprises the following steps: sequentially determining a current frame of a to-be-inserted frame video, a previous frame of the current frame and a next frame of the current frame; inputting the current frame of the to-be-inserted frame video, the previous frame of the current frame and the next frame of the current frame into a pre-generated video insertion frame model, wherein the video insertion frame model is generated by training a pre-set convolutional neural network model by a current frame of a training set, a previous frame of the current frame and a next frame of the current frame; frame insertion is performed on the to-be-inserted frame video by the video insertion frame model so as to obtain the video after frame insertion. According to the embodiment of the invention, better video insertion effectcan be achieved.
