Small advice - use some kind of de-blocking filters, smoothd is not bad, will keep some % of details on top of it throw dft. And switch to x265, it's still raw - but considering b/p rate, will be perfect for rips what focused on small size.
Just a heads up, you might want to prepare to update this soon. It suffers from no-progress bug that is currently under rapid debugging.
