Still trying to get this MP4 to play...

Nailed it. So I ask him "what resolution do you record at?" and he says "you mean bitrate?" So we do a quick review of resolution and then he asks "why would that matter?" Then his face lights up. While he's creating a test video, he explains why he didn't think that made a difference and why he said he "didn't change anything."

But he did. Now he's learned a bit more. 720p will be just fine for him, he doesn't need 1080p.

Thanks for sticking with me on this. I had logged into Twitch to see if there were different download options. I didn't realize there were recording settings on the xbox.

I never got the 1080p video to show a single frame, even with jog/shuttle. It also never stuttered, just played audio perfectly with a solid black screen.

There's at least a dozen or so posts out there with people having this issue, not specific to Twitch. Most don't have answers, and the ones that do mention transcoding. Congrats on being the only one who has figured out it's a resolution & GPU power issue, not codec issue.

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.

EDIT: MacTracker indicates that your MBA can handle up to 3840 x 2160 on an external display. That’s a LOT more pixels that 1920 x 1080.

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?

I was thinking the same. h.265 would kill it for sure.

Yes, it's h.264. VLC and QT both say that. 29.95 FPS. 1.98Mb/s.

Yeah, at this point I got nuthin.
