10月16日的Timelapse Video Maker应用程序分析

A timelapse video is a video that's been created by taking a series of photos at a regular interval (often a few seconds apart), then speeding them up and stitching them together. The result is a video that shows changes in the subject matter over time, but much faster than normal speed. For example, you might see a video of a flower blooming in seconds, or of a sunset in a few minutes.
