As I understand Nvidia uses CUDA code to encode videos and AMD has OpenCL. A person I know uses DVDFab for his Nvidia card but it does not support OpenCL (ATI) so I would like to ask what FREE software you guys would recommend for someone with an ATI card. Please recommend two different softwares so it's not bias on what you personally think is the best, but what you thing is the best and what you believe is the most popular. That way I can try both and make my own opinion. Thank you!
