Users can export WebM with fnord shareware. Users cannot import WebM files natively, however, which is the feature request. On behalf of editor, Carleana ♡@carleana_ ^KM
While not so many PPro users have requested WebM import support, the free plug-in from our friends at Fnordware should do the trick.
