This is a project where I'm building plug-ins for Google's WebM format to be used inside the various Adobe applications.
Right now there's a working WebM plug-in for Premiere Pro, along with a WebP plug-in for Photoshop. Both are considered to be beta releases.
Here are the latest binaries:
WebM for Premiere Pro v0.5b19, 2 April 2015 Mac | Win
WebP for Photoshop v0.5b7, 12 March 2015 Mac | Win
