alpha premult issues

Hi, having some issues importing a sequence with an (Straight not Premult) alpha channel embedded.

Rendered out of Davinci with Straight Alpha. In Fusion Studio I can see full RGB channel.

When I place directly into Resolume or Alley it Premults, leaving unwanted black RGB info around eye.

Any help most welcomed. Cheers.

When you fold open the extended properties, you get access to Opacity, Width & Height, Blend Mode and Alpha Channel interpretation of a clip.

Awesome thanks. Part of my issue was also rendering the MOVS as DXV with straight alphas in the firstplace. Both ends of the issue work now. Thanks again mate.
