This commercial is typical of much of the account work I've worked on. The main International version was re-edited to fit with a UK voice and UK compliant claims. International creative supers were then copied and amended, all allowing time for UK legal supers. It was done first on avid or Smoke on a mac, then onlined on Smoke Advanced.
I highlight this commercial as the final CCG Glossy Blacks tag was made entirely in a 3d environment on Smoke, from flat pack artwork, which was manipulated and re lit over a hand made background.
