I took a one-minute time-lapse photo with my mobile phone, but it only took a few seconds to save and play. What happened?

Hello, I'm glad to answer your question!

First of all, we need to know what "time-lapse photography" is. Time-lapse photography is a compressed recording technology. Its main feature is to shoot pictures or videos at a low frame rate. Simply put, it is to record faster (frame rate) video than before.

It is a kind of time-delayed video, which we can understand as fast playback. You took 1 minute with time-lapse photography, but the frame rate of this minute was modulated into a frame rate of several seconds by this photography technology, so it only took a few seconds, and you can find that the video playback speed (frame rate) is very fast (high).

If you want a longer delayed video, it will take longer to record.

I hope I can help you!
