Apple TV 4k Split Green/Red Screen

Hello Community!


I have a problem with the Apple TV 4k and HEVC encoding at 2160p. When trying to play the video, my TV shows a split (side by side) screen with only Red and Green colors. What is weird, is that the progress bar on the bottom is able to display the preview of the video as it should be as you can see in the photo below:

I've tried different encodes (Peak 30 frame rate, 10Bit,etc...) all as testers but all have shown the same results. I've also tried H264 encodes with 5.1 profile and same issue. At first I thought cables, so I swapped out for HDMI 2.0 certified cables (3 different ones from different manufacturers), but same results. I then wondered if it was the TV (Samsung 4k 2017 model year) and went through and enabled HDR on all the ports but still same results. I tossed the video onto my Roku Ultra using the same cables and the same ports on the TV and that same video plays perfectly. This leads me to think the Apple TV is the bad apple in this bunch. I've added the video to iTunes, and the video plays fine within iTunes on my computer.


I've encoded it using Handbrake nightly to get the hvc1 ID that Apple requires. Video details are below. Everything I've read so far leads me to believe that the Apple TV 4k should play this file no sweat...

I used a program called MediaInfo, you can grab it from mediaarea.net/en/mediainfo. Once installed, you right click on the video and then select it. From there it displays the relevant information.


I got digging deeper, and I think the problem relates more to Handbrake as my source was HDR. Handbrake doesn't yet support HDR processing, so I'm thinking this is where the break is. It plays fine on my computer, but the AppleTV isn't capable of decoding it as well.


If I choose a non-HDR source, and run through the same steps, AppleTV seems to play it fine.
