High resolution frames from an animation

Core Library Questions

Hi.
This is my first attempt at Processing, sorry for the silly questions.
I need to save frames at 300 dpi minimum for professional printing.
I tried to use a frame 4 times the size of my monitor, but I really need to see what's happening when I record so it does not work for me.
Instead I tried to use the PDF library but I only save 'blank' frame, I don't understand why.
Is there a better way of saving at high resolution, if not, can you tell me what's wrong with my code?
Thank you for your help!

int num = 60;
