Hi everyone, I love Sony Vegas but I've always had big problems rendering.I have a GTX 570 with CUDA architecture; after having activated the plug in render Mainconcept AVC, after having activated in the settings "allow legacy GPU rendering", when I try to render with the above mentioned plugin and activated the mode of encode mode in "Render using CUDA if available", the rendering part, the frames always remain at zero and the timer always increases ..... with a black screen in the preview.I think I'm wrong and I hope someone can help me solve the problem.
