Honestly, recording costs a lot. If you have a NVIDIA card, use Shadowplay, it's virtually free performance wise and higher quality.

Other option is using Dump Frames and Dump Audio options present in Dolphin. Game may lag during frame dumping but the resulting video file will be at fullspeed, you'll only need to join video and audio togheter...
