How to adjust the speed of mobile phone time-lapse photography

When Apple's mobile phone or pad system is upgraded to IOS8. 1 (the previous mobile phone and pad didn't support hardware, so it's useless to upgrade to the latest system in time), the camera function of the mobile phone will have functions such as time-lapse photography and slow motion. Time-lapse photography is a very fast shooting. To put it bluntly, it is to compress a one-minute video that was originally played normally into a few seconds. And the function you said is slow motion. Is to slow down the normal video playback. These two functions are very simple, just a little operation. If you want to play your own slow-motion video on your computer, please see this website:/read-htm-tid-8195200.html.
