To take a time-lapse video, you’ll need to use either an external power bank or a video function card. If you’re using a function card, all you’ll need to do is insert the function card into the camera and go to the 4th filter and then click the shutter button on the front. If you’re using a power bank, use the USB cord that came with the camera to connect the power bank to the camera. You’ll then do the same thing, go to the 4th filter and then click the shutter button. You’ll want to set your camera up because it’ll take approximately 30 minutes to create a 10-second time-lapse video. The camera needs to be left in the same position as it will take a photo every second for 30 minutes. We suggest propping the camera up and leaving it alone until the time is up. After the 30 minutes, give your SD card just a few minutes to compile all the photos together to create the video.
