Remedia
Watching
Picture and sound formats
When your Apple TV can play a file, Remedia plays it as it is. Nothing is converted on the way.
HDR and Dolby Vision
Remedia plays HDR10, HDR10+, HLG and Dolby Vision, on a TV that supports them.
| Dolby Vision in the file | How it plays |
|---|---|
| Profile 5 | Dolby Vision. |
| Profile 8 | Dolby Vision. On a TV without it, the file's HDR10 or HLG picture. |
| Profile 7 | Dolby Vision, converted as it plays to the single-layer kind an Apple TV shows. From a disc with a full enhancement layer, that layer's brightness is carried into the picture and its fine detail is not. On a TV without Dolby Vision, HDR10. |
The Apple TV settings that matter
For the TV to switch into HDR or Dolby Vision for a title, the Apple TV has to be allowed to. In the Apple TV's own Settings, open Video and Audio, then Match Content, and switch on Match Dynamic Range. Match Frame Rate is worth switching on too.
Video
- H.264 and HEVC, up to 4K, are decoded by the Apple TV's own hardware.
- AV1, VP9, MPEG-2, VC-1 and MPEG-4 Part 2 are decoded by Remedia itself.
Sound
- Dolby Atmos is passed to your sound system when it is carried in Dolby Digital Plus, which is how streaming services and most downloads carry it.
- Dolby TrueHD and DTS-HD Master Audio are decoded by Remedia and stay lossless, up to 7.1. No Apple TV app is allowed to pass them to a receiver untouched, so the receiver shows PCM.
- The height channels of Atmos in TrueHD, and of DTS:X, are not played. Those tracks play as their 5.1 or 7.1 sound.
Checking what is playing
The badges on a title's page (4K, HDR, Dolby Vision) are what your server says about the file. To see what is happening in the player, open the Details pane while the title plays. It shows whether the file is played directly or converted, the picture format and what it is playing as, and each audio track.
Streaming quality
In Settings, Playback, under Streaming Quality, there are two choices: Home, for your home network, and Away, for anywhere else.
- Original plays the file untouched. It is the default at home.
- Auto asks your server to convert only when your connection needs it. It is the default away.
- A fixed rate, from 20 Mbps 1080p down to 720 kbps, converts anything above it. A converted picture has no HDR and its sound no Atmos.
Converting is done by your Jellyfin server, so it needs a server allowed and able to transcode.
Sharpening older video
Upscale SD and 720p, in Settings, Playback, sharpens low-resolution video with Apple's upscaler. It uses more power, and stops by itself if the Apple TV cannot keep up. HDR, Dolby Vision and Live TV are left alone.
