Alpha video on Designer Beta

When you launched designer beta, you mention that Alpha video will be supported.I followed the steps you recommended, but when I imported the WebM video into designer, nothing happens, still getting the black background.
What do I do?

Hey Planmundo!

Sorry that you are having trouble with getting your alpha video to play correctly in Designer. Do you think you could send the file to us at support@zappar.com so the team can diagnose what has gone wrong?
