Does “with alpha” work? #54

Thanks for building this encoder!

I exported a video using the encoder using VP8 and ticking the “include alpha channel” checkbox. But when I load into Premier Pro and put another video layer behind it, it does not show through. (If I use QuickTime/GoPro with Alpha it does show through - the transparency works.)

How to verify that the transparency is actually working?

(I want to load it the video up in Unity 3D to play back with transparency - WebM is one of the supported formats - but it does not show transparency there either. But I am new to Unity, so may be doing something wrong.)

I meet the same problem and found that the problem is Adobe Premiere Pro can not recognize the alpha channel of WebM. My transparency background shows black in PR.
