In step S206, delete the video content corresponding to the time period;

In step S207, the preset transition video content is inserted into the video stream corresponding to the time period to synthesize a complete video.

As a preferred embodiment of the present invention, after the step of setting the end time, it also includes:

judging whether the total time length from the start time to the end time is less than a preset third threshold;

If the total time length is less than the preset third threshold, it is determined that a transition is not needed, and the recording time is cleared.

For example, when the user has a violent movement and the shooting angle changes during the video shooting process, the mobile phone detects the acceleration a during the video recording process through the accelerometer, and if a>amax threshold value, start timing and set it as the start time, And start to record the angle change of the mobile phone with the current position as the initial coordinate through the gyroscope, and take the unit time t as the time interval. If the cumulative angle change within the time t is less than a certain value, it is considered that the shooting state has been stabilized, and the timing is stopped. Set to End time, if the total time length from the beginning to the end is less than a certain time threshold, it is considered that the time is too short, no transition is needed, and the recorded time is cleared. After the shooting is completed, the mobile phone will begin to identify the start time and the end time; the time period between the start time and the end time is determined as the time period of the video transition. The video content corresponding to the time period is deleted; the preset transition video content is inserted into the video stream corresponding to the time period to synthesize a complete video.

It can be seen from the above that the second embodiment can automatically remove the transition content and jittery video content that the user does not want to keep, effectively reduce the technical threshold for the user to shoot video, and can automatically add the pre-set video transition screen, This makes the content in the user's recorded video excessively natural, and is an effective segment that the user wants to keep, thus greatly improving the user experience.

In step S403, delete the video content corresponding to the time period;

In step S404, the preset transition video content is inserted into the video stream corresponding to the time period to synthesize a complete video.

For example, when the user moves violently during video shooting, the captured image is blurred. In this way, the mobile phone can recognize that the blurred image is a video that the user does not want to keep. Therefore, after the shooting is completed, the mobile phone It will identify the start time point corresponding to the first blurred video in the video stream, and the end time point corresponding to the last blurred video; determine the time period between the start time point and the end time point is the time period of the video transition.
