    Best way to convert a black background to an alpha channel?

    benjamino5 Level 1

      I have an animated lower third with shadow effects (so one edge blends into blackness). The problem is that this lower third exists only as a QuickTime file with pure black background--the original Photoshop layers are no longer available, and we don't know what app was used to make this.

       

      So I tried a couple of tips I saw online - Shift Channels to set the Luminance to the Alpha channel, for example, but that didn't get me anywhere near a clean alpha channel background. What's the best way to handle this?

       

      Thanks!
