I am totally new to vvvv, and when I wanted to create a simple ‘black becomes transparent effect’, I found the alpha_video effect. Only the strange thing is that I see the ‘visible’ part of the video twice, one of them mirrorred.
So I started editing this shader, and even with this very simple function, I see the ‘normal’ image (video or file texture), and I see the ‘mirrorred’ image shine through the first one, and it gets more visible when I decrease the alpha value.
float4 psAlpha_VideoBetween(vs2ps In): COLOR
//source texture lookup
float4 outColor = tex2D(SrcSamp, In.TexCd);
outColor.a = 0.8f;
Does anyone know why this happens? Is it normal, or do you think it’s a problem with my specific setup (working on a XP SP3 laptop with ATI Radeon X1250)
