It's been a while since i last used node based post processing so i'm sure i'm making a rookie mistake but i have a problem regarding the rendering of image sequences. in this case i want to have multiple sources displayed at the same time and then overlay a logo and then fade to the blue BG color. Everything looked fine in the viewer, but then i tried to render it out.
at first it didn't work at all and then when i did an unpremult at the end i can render mp4s with the desired result. but when i try to render TIF or TGA image sequences the only "visible" source is the last one in the merge order.
Any suggestions on how to go about fixing it would be greatly appreciated. here is a screencap of the node network.
This is the result if i try to render a image sequence:
