Where did a person shoot the video of Aauto walking faster?

Fix the captain with a tripod, press the screen to lock the exposure, shoot a video of yourself walking first, then shoot a traffic flow with time-lapse photography, open JYAPP, import the video of yourself walking first, and click the picture in picture. Add a time-lapse video, click Edit, and then click Cut. Cut out the appropriate parts and adjust the size and position of the picture. Enough to make the two pictures match perfectly.

Do it a few times more, and you can't shoot it at once.
