I use Vegas Pro 13, I have a serious problem of the texts resolution.

I first added texts in the project properties setting to 480p, after finishing adding texts, I change the project properties to 1080p, but the texts didn't change to 1080p automatically, they remained at 480p and looked really blurry.

I need to change the texts frame size one by one, is there a way to apply all of the adjustments to whole texts? Changing texts on each one are really slow. Thx!
