Storyline 360 now supports transparent WebM video

I'm glad to see this, as it makes a much cleaner presentation. I've been working around the MP4 limitations for years and while workable, this makes everything so much simpler. As the logical next step, and not particularly difficult, I would suggest offering user support for chroma keying video backgrounds. I posted an example of how to dynamically key out greenscreen videos a while back on ELH. Since the media library offers numerous greenscreen videos, and greenscreen stock may be easier for many users to find or even create on their own (versus fully transparent video), this would enable even more design power for users.

Although my example is fairly straightforward, it is well beyond the skill of many SL users. I'm sure having a feature like this built-in would be appreciated by many.
