Is there any way to counter the transparent background showing as black? I have tried using a "Set alpha" node, but that has failed.

I was recently asked to add legible images. My bad. Here: enter image description here

Edit 2: The mask is intended to be used as an animated overlay. Edit 3: Add because I had no idea Alpha Over was a thing in Compositing nodes, and using Add here seems to do what I need it to do.

FOUND IT!!!! I HAVE FOUND THE ANSWER!

In the previous images, the node setup depicts the involvement of a "Mix" node. If you change "Mix" to "Add", you will obtain the results seen in the image here. The transparency targets everything black, resulting in what you see. enter image description here

  • $\begingroup$ This gets even better when you change the color space to "Raw", not "sRGB". cdn.discordapp.com/attachments/185590907947581440/… $\endgroup$ – Darknaviexe Nov 14 '16 at 0:38
  • $\begingroup$ Don't ever change the View transform to Raw. It's completely bogus and a complete mangling of the system. I'd also suggest that this answer is a complete mangling of comprehension about alpha and how it works, but I can't tell entirely from the sparse information. Perhaps if it were fleshed out a little more, a more fitting answer could be provided. $\endgroup$ – troy_s Nov 14 '16 at 4:00
  • $\begingroup$ So, avoid Raw at all costs? Also, how do you want this to be fleshed out? What details do I need to provide? I want this to be as clear and concise as possible, but I have no idea of what to do. $\endgroup$ – Darknaviexe Nov 14 '16 at 4:35
  • $\begingroup$ Raw is the View transform, and entirely irrelevant to your compositing needs. I suppose I would echo @cegaton's outline and ask more clearly what exactly you are hoping to achieve, what your two plates are individually, and what you are hoping for. Fair? $\endgroup$ – troy_s Nov 14 '16 at 4:43
  • $\begingroup$ @Darknaviexe Remember that we have no idea of what your are trying to do, and the images are not showing your intentions clearly. Please edit your question and clarify: What are you using the mask for? why are you using add instead of alpha over? please read; blender.stackexchange.com/questions/49049/… $\endgroup$ – cegaton Nov 14 '16 at 5:22
