Problem with NDI alpha (artifacts)

[maxislo]

Hello!
I have problem to send NDI alpha from VMIX to Resolume 7. (black lines - artifacts)
In the NDI Studio Monitor and another Vmix everything is clear on alpha)

Have you tried to change the NDI clip's Alpha type setting in Resolume?

[maxislo]

If you mean "Straight" and "Premultiplied" - yes. Both of them. (I tried both of them in Vmix too)
Version is Resolume Arena 7.1.0 PC

[Zoltán]

Yes, that's what I meant.

Can you also send some screenshots from Vmix, and NDI monitor with Checkerboard switched on?

I have tryed on the another set up (and version of Vmix) and everything was fine.

I was having the same issue after I just upgraded Touchdesigner. Touchdesigner is now on 4.1.4 NDI. Resolume is on 4.0.1. I copied the Processing.NDI.Lib.x64 from the TouchDesigner099 bin in the program files folder and pasted it into the Resolume Arena Program Files folder.

That did the trick to get them both on the newest version.

Hmm, interesting, thanks for letting us know!

I did open a ticket for Propresenter because i thought it is their software's fault but noticed that other has the same problem that i have with propresenter. Artifects next to the element that has contetnt over NDI with alpha channel enabled.

Turned out to be an issue with the NDI libraries indeed. We'll have a fix for this in Resolume soon.
