This sounds a lot like the problem we used to have transcoding GoPro h.264's on version 6.5. Similar scenario - very short clips would make it through but longer clips would crash out and I'm pretty sure it was the same error message that I used to get to. A point update fixed the issue for us although it was still very slow.
Avid seems to really hate h.264 material. I've had some success transcoding problem clips in the background rather than using foreground transcode. If that fails, I just go to Resolve.

This is a Westemere machine, from mid-2010, so more like top-of-the-line Mac from 5 years ago, unless I'm misunderstanding you. Multi-core benchmark is I think comparable to the 8-core trashcan Mac.
It copes with transcoding Epic R3D files from 4K and 5K, and likewise can handle F55 4K footage. It is specifically the GH4 that bogs it down, and it's not like H.264 quicktimes are a new-fangled file format.
Do you have a setup that handles the GH4 4K successfully?
I have an 27" 3.5GHz quad-core i7 iMac, and could load it with MC 8.x. That would certainly be a newer setup, but apart from it's video card it benchmarks lower than the Westmere, and it has less RAM.
Suggestions appreciated,

I hate to say this, but you do realize you are trying to get this 4K thing to work on a machine that is 9 years old technology, right?
