This week, I recorded a lot of extra materials to enrich my videos. In the process of making the video, I tried to make the transition of the video more interesting, such as adding special effects and audio jams. At the same time, I also set up some swings of the lens transition, such as when switching the lens, it will rotate according to the direction of movement of the items in the lens. At the end of the video, I shot two sets of shots at different times in the same place and edited them together, giving people a sense of time travel.
