Incorrect blending of image with alpha
Posted: Thu Apr 20, 2017 12:59 pm
I am using Fusion to add animated title to Resolve. I export from Fusion as PNG frames with alpha channel. The clip is then put on top of other footage in the timeline and it blends using the alpha channel. This works fine -- as long as the title is not resized in any way. Once you zoom the title layer, or it is implicitly resized because of project frame settings, ugly dark fringe appears around the letters. You can see this in the linked image (note the zoom values).
My original idea was that Resolve is interpolating the title in gamma-corrected space instead of linear space (the correct way). But I couldn't recreate the effect in Photoshop, so I am not sure if that's what is happening. Any ideas?
