Alpha layering problems (glitches and dots)
Hi there. I have a problem with layering cg-layers in vegas. I have a solid layer as background and now i want add an additional layer with alpha (premultiplied). Now, the composed frames look good when suddenly there are many colored pixel dots in the picture for just one frame. sometimes it lasts for 5 frames, then 3 seconds everything is fine again, then there are these pixel dots again (like colored grain).
when i turn off the alpha/layer everything is fine again.
The pics themselves are clear and working (AfterEffects is doing fine). So it’s Sony that wrecked the picture. Even rendering is doing so.
Is there something wrong with my pc?
