Working on an intro for a religious broadcast.. I have a tif sequence for the torso/head and a photoshop .psd for the legs and lower torso.. This is going to be a quick zoom out so it doesn't have to be a perfect composite, but the gray around the edges of the matte is noticeable even with a bit of motion blur. Does anyone know what is causing this?
You sure you're video layer of the guy is key'ed out cleanly? Thinking maybe you rendered it out as premultiplied alpha and Maya isn't interpreting it right. Try rendering out a straight alpha matte that's choked down and see if you still get the white ring, if so it's maya if not it's the source.
Strangely enough.. I have noticed when I change the background color in photoshop.. (even though that layer is removed on save/export from photoshop) it effects the color of this distortion on the alpha edges.. The mask was created using the polygon tool and creating the alpha from the selection..
