Alpha channel blending with GPU?

@zanetti
Possible to upload a bigger screengrab? When I try to zoom in to see the actors, its too pixellated.

@primaldivine you just have to click on it than it appears bigger. it is native resolution of my screen, so cant go higher

Is there any plans on a GPU Chroma Key?

DusX

@Ubik there are big plans

@zanetti please test if bypassing Gaussian Blur fixes the issue for you.

Hi @DusX Yes deactivating it is fixing it, but i need it. The difference ist that before i was using the alpha mask actor, which mixes two images somehow neatly with a third image, the mask. but the addalphachannel obviously delivers a black backround with one image within the alpha channel. if i blur that, there is gonna be black in the blur too...i'll try to workaround it

Dear @zanetti,

I'll have an update for you tomorrow morning that will allow you to handle the dark halo.

Best Wishes,

I have the same problem as @zanetti when connecting a 'syphon to texture' actor : no output from FFGLAddAlpha... If I connect the syphon actor directly to a projector, I can see it works perfectly. MBP i7 2.3 Ghz 16 Go RAM OSX 10.8.5
Edit : in fact, same problem with the syphon to texture actor when connectoed to 'video mixer', 'video fader', 'threshold', Im going to start a new thread about that.

The Syphon to Texture issue is addressed in an upcoming release.

In the meantime using syphon to video and converting will work in all cases.

Thanks, it does the trick for now.
