It seems that Resolume may be using the wrong alpha type (straight vs premultiplied) for an NDI source coming from Adobe After Effects (CC 2017).
There is no Alpha Type option for the NDI source. Perhaps one is needed.
The sample screenshot shows smooth gradients and edges on the bubbles in AE (on the right) and the left is a full-screen Advanced Output slice on an external screen. New composition with just the NDI source loaded in Layer 1.
I tried the Spout AfterEffects CC2017 plugin as a comparison; in Resolume the Spout Server source has an Alpha Type option. The default setting, Premultiplied, produces the correct result. The Straight alpha type option produces a bad result that looks like the sample NDI capture in the original post.
We indeed only accept premultiplied at the moment on NDI. But for some reason, it is showing the straight optioned compared to spout.
I've tested the Spout option and with straight it indeed seems not be working completely fine. I'm not getting the same results as you with white borders. But I'm not getting the results that I'm expecting.
We will look into it and in the meanwhile, I would suggest to keep it on premultiplied with Spout
I'm also getting the white outline (and compressed image) as if it were straight rather than premultiplied. I noticed it after I did the most recent update to v6.05. And definitely need that to work as intended! Has this been narrowed down to a Resolume issue? (not that I'm upset! love Resolume! just trying to find a way to fix this and still use NDI).
