IMAC 2017 - H.265 Video's

Hi All,

I have just bought a new 2017 27" Retina 5K IMAC with a view to editing my Go Pro 6 HVEC 4k videos, however it doesn't seem as though it can play the higher 4k @60fps video the Go Pro can pump out. If you drop the video resolution to 30fps everything is fine. I was told that the Mac OS High Sierra is up to the job as is my the Radeon 575 graphics card but still no joy I am afraid. Sound works but the video image just sits on the first frame.

IMAC has an Intel i5 chipset running at with 3.5Ghz with 16GB Ram so plenty powerful enough I would have thought.

Anyone know what the problem could be and indeed if I will ever be able to edit my Go Pro vids?

Cheers
Bruce

Wonderful, iMovie on my IMAC works perfectly with GoPro6 H265 60fps movies, didn't need to do any codec transcoding work at all it just worked
