So I got a VP9 plugin for my video editor, and with it reduced fill size by over 50%! The webm files had meta data for 4k (my resolutions) even thorough the frames were only 1080p. I went through and re compiled all the webm files with no 4k meta data.

Update contains
Duck team, 55 renders and 11 webm animations
Mallard team, 45 renders and 11 webm animations
File size reduction from 7.29 GB to 2.97 GB
Sorry no Kuromorimine this update, It has been pushed back to 0.14.0 because of the great compression.
