Dark Scene Artifacts/terrible contrast

[jmassaro87 28]

I’ve got some really terrible contrasting/artifacts happening when watch Emby content on our AppleTV 4K. It doesn’t happen with streaming services or on other devices running Emby. I am using a Synology Ds418 play as my server. Everything is hardwire Ethernet including the AppleTV. What might cause this? One photo is my tv, the other is my iPhone. You can see in the lower right corner what I’m talking about plus how much lighter the image is on the TV

Here is a server log.

More info about playback, MPV or native player? Direct play, direct streaming, remuxing...? Is there an ffmpeg log?

Every time I have ever checked, it has always been DirectPlay, not entirely certain about this specific instance. I attached a server log from last night. We watched the movie in the screen photos at the 19:17 mark in the logs. How would i go about getting all of that information?

The last ffmpeg log for the system is from 4/1. May contain applicable information as it has always been this way, just never really thought about it until last night when we watched a Netflix movie and it just randomly popped in my head that it was crystal clear. Then we watched a movie in Emby, and it was artifacty in the dark scenes. It's likely always that way, but highly noticeable in the dark scenes. I always wrote it off as maybe quality of the files being played, but its every file regardless of quality or source of the file.

Here is me watching the same movie, but remotely, with zero issues. I will try again playing it on the appletv when I get home.

Try disabling MPV player in Apple TV app, to see if there are differences

This actually made a HUGE difference. It also brought back the "next episode" count downs as well. Thank you!

I get better results with the native player, the only drawback is that what is not supported must be transcoded.

This resolved the extreme artifacting I was getting, as well.  This works great in the Emby app on my Apple TV but Infuse seems to still have the same issue.  Is this some sort of server side issue I can resolve within the Emby settings? 

 

I have no idea if it's a matter of tone mapping or something.  My streams are all direct play, so it's not as if transcoding is going on

I've been running this method for about a month and, while it has gotten rid of the artifacting, the player is buggier than the default Emby player.  For example, if a stream is left paused for more than a minute or two, it seems to cause audio to get out of sync by a few seconds.  I have also noticed issues with it looping back a few seconds every once and a while.

Has anyone else found a better fix for this?

I might have found an update here:

It seems that, in the Apple TV system settings, going under Settings -> Video and Audio -> and then enabling the Match Content settings might have alleviated my issues.

I'll report back after further testing.  I'm interested to see that it doesn't seem to be an Emby or Infuse issue, and instead, potentially an issue with the config of the Apple TV, itself.  Regardless, this has been a major annoyance for me so I'm ecstatic to have found a potential solution!
