I am responsible for video editing and copywriting in the project. I also participated in the demonstration of the importance of running to elementary school students in our school with some other group members. The most challenging part of my work is definitely video editing, which took me about a week to have it done. Time management is the key during the process of video editing, which may take more time if not done properly. Throughout the project, one thing that I learned is the importance of cooperation. Even though it is a complex project, with each group member engaging in to finish the project, things can be done quickly and efficiently. Every group member has their own specialties and with proper distribution of work, everyone can fully focus on their preferred tasks.
