WebM with alpha/transparency???

Report · Oct 07, 2015

As FLV is a dying format and often not supported, I found the plugin for WebM for Premiere. Does anyone know if WebM supports alpha/transparency? If so, how is that done? If not, what are my alternatives when in AME, PP or AAE? This is for a website, so of course, codec compatibility issues aside, the Animation and CineForm render files that are much too large anyway. I'm surprised that there's so little information about this. And whatever info I have found has lead me SMACK into a brick wall.

I installed an earlier version of After Effects to output a FLV for the webmaster, but that takes me back to the first point I made in this post.

Please help! Thx!

EDITED POST TO UPDATE:

I worked around this by giving the webmaster an AVI with alpha, 480x720, rendered out of PP. But I'm curious how long before someone has a solution, or a better alternative to my AVI.

Unfortunately, I think only Chrome renders that movie with alpha. It's not really a standard.
