create: write H:MM:SS timestamps, add option to fill with gaussian-blur instead of black

many albums are longer than one hour so writing H:MM:SS is a
necessity. if anything there will just be verbose info that
isn't important for my use-case.

however the gaussian-blur is simply broken. It works, and it plays
locally just fine, but YouTube in particular elongates the video
to fit the full width. I'm not entirely sure why it does this, but
it makes it useless and ugly.
