HEVC encoded MP4 judders on Quicktime for Mac

Hi everyone,

I'm feeling pain with Apple's Quicktime Player on High Sierra. It seems no matter what settings I use for my encoding, the video judders when played back with Quicktime Player. On the same computer VLC is able to playback the same videos buttery smooth.

My video is a screencast that is set to 1920x1080p, 29.97fps, and the HEVC settings I am using that seems to yield high quality results with the smallest file sizes is:

Average bit rate (kBit/s): 2400
Maximum bit rate (kBit/s): 8000
CPB (kByte): 1500
GOP Structure: Auto
Maximum GOP Length: 30
Profile: MAIN
Level: 5.0
Coding quality: Best
Hardware Encoding: false
Streamable: true

When I playback with Quicktime, I see the CPU is barely active and the GPU is running at 30%.

Is there some trick to getting Quicktime to playback my video as smoothly as VLC? I hate software! This should just work, I want my users to be able to view my videos without downloading VLC!!

Thanks,
Dave
