I have created a few videos, with lots of layers and keying (so quite complicated) on a composition size of 430 x 242.
The client has now decided he wants them as 1280x720.
Is it possible to make the composition bigger? Obviously I don't want to start the editing again due to the 3 days the project has taken due to the complexity of the editing. Ideally I'd like to use what I have, but just increase all of the dimensions.
