FFmpeg options for Apple TV 4K

[Aleksid1]

Hi,

I converted my 4K home videos to H.264 using FFmpeg and default options for libx264 + AAC audio. iTunes doesn't accept converted videos for Apple TV 4K. No problem with converted 1080p videos.

Are there any known issues with Apple TV 4K, or I should use certain options for 4K H.264, or I should create HEVC video?

4k may be not supported, try HEVC - also read vendor recommendations - usually every vendor provide such things as recommended formats and advise on encoding settings.

Thanks for you reply.

Apple declares: "H.264/HEVC SDR video up to 2160p, 60 fps, Main/Main 10 profile"

So I assume that it should support 4K in H.264.

Then is should clearly specify something like H.264 HP@L5.2, It looks like 4k is supported but on H.265/HEVC.

Official spec is even more confusing:

Wiki says 5-th generation only:
