The Process:
I did a survey asking people what they use a weather app for and the vast majority of people either answer check current weather or check future weather forecast. Watching weather videos was not selected at all and it's the videos that can use a couple of megabytes or hundreds of megabytes very quickly depending on the quality of the video so I decided to no include any videos on this app.
People like visual representation of current weather, but the visual graphics don't need to be animated. I decide to use simple static vector shapes for the graphics which works just as effectively and does not slow down the phone as it loads in because static graphic load a lot faster than animated ones.
