I am animating the title of a clip, I make it transparent by mask text+invert. I have a dark rectangle behind it so the clip under appears through the letters. I am animating the scale of this text making it big until the clip appears through the letters. I am using scale for this but I think there is a better way? When the letters are very big it seems the resolution of the letters gets bad. I have tried to animate the size by keyframing the size of the text hut this can not be done linear, it is a step-vise change. How should I do this?
