This is an animated video I made for the company's new set-top box. The video of just a few tens of seconds made me liver for a week. On the way, I encountered many problems, such as Catton in half of the computer rendering, and the files output by the video could not have Chinese characters, thus wasting several days. Finally, after solving many problems, I finished the finished product. This is my second time to make a video. There are still more or less problems. I hope you can give me more valuable opinions.
