I got the Nuke scene from Gonzalo. The shot has been already keyed. However, I tried to improve the key because alpha had some visible holes and rough edges.
The main task was to create a weather motion graphic. First of all, I made an orange box by creating a constant and applying a roto mask. To make the box nicer, I also add stripes. I created the stripes using modified checkerboard. I animated the box using the transform node. I had to adjust pivot point and animate y scale axis.
I downloaded weather icons with alpha. I created a transform node and animated scale. I modified the curve inside curve editor to make the scale animation more smooth.
Then I used the transform node for each weather icon. I also used the time offset node to offset the animation. I created a text that I combined with roto mask. To make the text fade in, I had to animate the mask. Then I just duplicated the text few times.
