Unable to get High Definition Video Demo on MacBook Pro

Hi,

I'm currently exploring Adobe Captivate 2017 and want to capture high quality screen on my retina MacBook pro. Captivate is able to capture my screen but the quality is very
poor. Can you please guide me how to get HD quality or Retina quality screen capture using Adobe Captivate?

I've the recent Captivate 2017 trial edition installed.

Any help would be highly appreciated.

Thanks
