54 meg files?????
whoa you don’t need that much resolution.
Don’t mask or roughen edges to the journal, AE is re calculating the mask and the roughen edges every frame , also turn off motion blur until you render or just put it on to check frames every now and then.
It’s always best to prep your files in Photoshop don’t use layers unless you really need them (if you wanted the letters to fade in).
good luck
