With some resources on Google, combined with simple graphics and motion, everything is done by Nuke.
For a weather forecast similar to this, chroma key commonly used in filming because the color is not present in skin tones and is not commonly worn by people. Therefore, as the main character, Louis, was not wearing green outfits, it is easier for me to use Keylight to remove the green screen.
Combined with other elements I found online, to show info at the lower third graphic and a list to show next week weather, the result is satisfying to show as a weather forecast I saw on other typical TV program.
By the way, I found this blog quite useful to gather the most common Nuke shortcuts that I need.
