When WebM is the right container

Some sites, Chrome Web Store listings and HTML5 players still want WebM. An MP4 will play in most browsers; WebM can be smaller with VP8/VP9.

If the source is already VP8/VP9, we remux. H.264 MP4 is transcoded into a WebM the browser can record-style play back.

Safari support for WebM is better than it used to be but still spotty. Keep an MP4 around if you need Apple devices.
