Apple's 4S video takes up a lot of memory, how to deal with it?

Iphone4s video takes up a lot of memory and can be set by the following methods:

1. First open the information application on the iPhone4S, then click the Write New Message button in the lower right corner to enter the short message interface, then click the camera icon on the left side of the short message input box, and then select "Take a photo or record a video" from the pop-up options to enter the camera interface.

2. Shoot the video as usual, click Use after shooting, return to the information editing interface, and then click Cancel in the upper right corner. At this point, the video has been automatically saved in the album.

3. The resolution of the video shot by this method is 480x360, and the file size is only about 1/30 of the default HD video of iPhone4S. As shown in the download, the default HD camera mode of iPhone4S is 29M, but the video file shot in this way is only 1M, and the video frame rate is basically the same.
