So currently make some stuff for my stream, Animated Pop up when you get sub/follow/donations Etc etc

This was based of a tutorial i was watching. But my outcome vs there outcome is totally different.

Is there a better way to go about Making something Webm and keeping transparency


ill render the animation in Adobe Media Encoder,In Quicktime Like so



Then Render it, But when i go to Convert it from .Mov to Webm It is not transparent and gets this outcome



Also Looking for a program that can convert to Webm without these websites trying to charge 10$ for XX amount of MB usage
