Choppy 4K Video Playback

Good morning, I am shooting video on a DJI Mavic Pro drone at its default settings (4K, 30fps, .mov). When I try to play the video back in QuickTime or in Photos.app, I experience stuttering and choppiness when viewing on my brand new late 2016 MacBook Pro (touch-bar, 8GB). This hardware should be more than sufficient to play this footage, right? The odd part is, sometimes the same clip will lag, and sometimes it will playback smoothly. Any advice?

can anyone confirm if this is a 13 vs 15 issue with the dGPU
 
This is most likely a CPU issue as viewing a movie is joint effort between the feeder of frames (GPU) and decoder of said frames (CPU). See what the CPU is doing when playing back.
 
VTDecoderXPCService is at 180% of CPU activity according to Activity Monitor when the 4k video is slowing down. What would cause this? Can playing back a short 4K clip really overpower the CPU when nothing else is running?
