Tracking moving footage is always tricky, but when that footage has a shallow depth of field, such as a closeup of a beer bottle label, it becomes even more so. I created clean "plates" of the labels at various states of the animation, then created a french version of the text to lay on top. There were about 3-4 shots to replace the labels, and the last shot even had a little jiggle in the bottle that added an extra layer of difficulty. In the end, you can barely notice these weren't real bottles with French labels.
