I wouldn't do much more with that. It's mono and it has a consistent crackle to it. (which shows up a lot when it gets quiet, which is nice) To do much more could get into 'overboard' territory. ;)
Agree.
I will share soon a short video (without sound for now) of the Obi/Maul's duel. I added a 18 fps filter, and I must say it looks good!
But god it takes time to render with all these filters! If I want to do an average 2 pass encoding, it takes almost 1 minute per second...
