Final Cut PRO 10.3.2 problem during rendering

[Excel-319]

Have installed Final Cut PRO 10.3.2 and started rendering some 4K from
My Typhoon H. Playback is not smooth and same problem after exporting video. My computer iMac with 24 GB memory and iCore 3.2.
Have not used this rendering program and are a beginner and need some help.
Video from typhoon 3840x2160 30p and have made a blu-ray video full HD
1080p but movie not smooth. Performed a test and did no rendering and put one clip on time line and no format change 3840x2160 30p and saved.
not smooth when play with Qucktime player. Original video from H no problem to play with QuickTime player.
Any setting in Final Cut PRO that i have missed ??
I hope i can use this rendering program.
