I dont know what else to tell you, check to make sure the original isnt blurry, other than that maybe look into Adobe Premier ProIt's blurry at times and it's rendered at those settings
If this was about the settings i posted then yes OpenCL will do the job just like CUDA as long as you have AMD card, CUDA is for NVIDIA GPU's, and OpenCL is more optimized for AMD cards.Thanks. I've been having the same problems too, and I think this might help. Trying to render with those settings now. I don't have CUDA though, would OpenCL work?
