Apple TV 4K HEVC/265 60FPS No Direct Play

Apologies if I have formatted this incorrectly as it’s my first post.

I have a 60fps 4K HEVC/265 HDR file that is transcoding to Apple TV 4K. Audio channels are TrueHD 7.1 and AC3 5.1. It transcodes down to H264 and AC3 for some reason.

All of other HEVC/265 4K content Direct Plays or Direct Steams fine. Is this caused by the higher framerate? I tried the enhanced player and the video and audio were now showing as Direct Playing but the frames were dropping like crazy.

Regular Player

Enhanced Player

Debug (Enhanced Player)

Another Direct Play thread, another recommendation to use Infuse Pro.

And what seems like a typical non helpful response. The objective here is not to pay for a service. If what I want is not possible without paying then c’est la vie. Only tested enhanced player to see if it would work.

atv does not support truehd.

Infuse decodes it to pcm (or Flac I forget).

See also Plex, 4k, transcoding, and you - aka the rules of 4k - a FAQ

I’m following the rules as all my other 4K content is working with direct play. Only the 60fps file is not. Question is if Apple TV player supports that high of a bitrate. All of my other files that work with Direct Play are TrudHD.

Ok maybe I’m misremembering.

Perhaps it’s the 60 FPS that’s the problem.

I’ll defer to one of the atv experts.

According to this article: Turn on Match Dynamic Range or Match Frame Rate on your Apple TV - Apple Support

ATV 4K supports 60fps… But some of their wording seems a bit tricky. I have no experience with ATV either.

It doesn’t work in the Plex app in ATV, even without transcoding. As the previous posters have said loads of dropped frames. However it does play fine in Infuse, so it’s not an ATV limitation but a Plex app limitation.

Also it’s nothing to do with the audio selected, even with the AC3 track which can be direct played you get dropped frames.

best bet is then

  • provide client and server logs exhibiting the problem
  • provide sample of file in question

With that title you will have to use Infuse Pro. There is no way to DIrect Play or Direct Stream without dropping frames using the tvOS Plex app.

On my Apple TV 4K, I can get 4K video to play just fine - even files that are 10-bit. Complete Direct Play, no transcoding. That said, all of my frame rates are 23.976 fps. I’ve never tried 60 fps.

Yeah all my other content is working great.

It’s a long shot but you could try to Analyze the 60fps video before hand in the web app.

Please get us the XML Media Info from that file while it’s playing.

Logs would be appreciated. Being a Direct Play, PMS and the ATV have agreed the ATV can handle the original track types, but not necessarily if the track bitrates are too high.

Are you using the Enhanced Player function on the ATV Plex app?
Are you running a Gbps wired LAN?

I am also having dropped frames with the same file. Works fine on my iPhone but not in my Apple TV 4K.

Is Plex planning on fixing this?

See the post above, they need logs etc to fix it. I’ve already watched it in Infuse and deleted the file.

Here is the XML data for the above mentioned media.
