Still trying to get this MP4 to play...

So let me get this straight: You’re saying that your 2017 MBA doesn’t have the git-up-and-go to play back 1080p video? I get that it has the integrated GPU, but still... that seems more than a little lame. 1080p video has been a thing since at least the mid-2000s.

I missed that from the previous thread.

Yeah, a 2017 MBA would have native h.264 video acceleration.

Just misses h.265 support. (2018's "Amber Lake.") Sure it's not h.265/HEVC?

...If it's 1080p h.264 at 60fps or less and reasonable bitrate (What is the bitrate? Less than 3500kbps?) then it should be fine on a 2017, even a MBA. So, there is still a mystery: Why does the 720p video work when the 1080p video does not, with all other stuff being equal?
