lightsout 144 Posted March 11, 2019 Share Posted March 11, 2019 Lets say I do a remux with a UHD blu ray, and want to re-encode it to a smaller 1080p file for other devices. I tried with handbrake but the color is wrong, looks like trying to watch HDR on non HDR screen. Handbrake retained the 2020 color space but I would like to covert it to 709. I am happy to store two files, until Emby gets tone mapping addeed to transcoding. But currently when I tried to re-encode a UHD HDR remux the resulting 1080p video is washed out. Anyone know how to do a proper 2020 to 709 encode? Link to comment Share on other sites More sharing options...
Guest asrequested Posted March 11, 2019 Share Posted March 11, 2019 It can be done with ffmpeg, but it's a hefty process. I'm pretty sure mpv will be able to, as well, but I haven't gotten around to testing that. What are you using to play the videos? Link to comment Share on other sites More sharing options...

But the info I have found is complex. I'm not a command line guy. I am not sure what mpv is I would be using an Nvidia Shield for playback. Or possibly a Roku TV. I am just curious for those obtaining their media legally, it seems like we need to make a choice of either 2160p or 1080p right now. I guess I need to keep digging in regards to ffmpeg.

Guest asrequested Posted March 11, 2019 Share Posted March 11, 2019 Its on the to do list, for Emby https://github.com/MediaBrowser/Emby/issues/3480 I've been meaning to test mpv with this. https://mpv.io/manual/stable/#encoding-o Link to comment Share on other sites More sharing options...

I guess I will just rip 4k and store them for now. And watch them on the main screen. Link to comment Share on other sites More sharing options...

rbjtech 4289 Posted March 12, 2019 Share Posted March 12, 2019 (edited) Ripbot264 has been my go-to encoder for years (ffmpeg under the hood) and it has HDR to SDR tone mapping built in via the GUI .. It's a hefty process though and from what i read, single threaded, BUT ripbot has distributed encoding, splitting the video file into sections to allow multi-cpu/thread utilisation.. You'll need version v1.22 onwards (v1.24 is the latest) v1.22.0Added: Support for UHD BluraysAdded: Automatic HDR information retention while encoding to HEVC format Added: Automatic HDR to SDR tonemaping during conversion to AVC formatAdded: Option to limit MT usage to specific filters onlyAdded: Custom Script optionFixed: Various fixes and improvements Edited March 12, 2019 by rbjtech Link to comment Share on other sites More sharing options...
lightsout 144 Posted March 12, 2019 Author Share Posted March 12, 2019 If you use an HTPC with Theater desktop, you won't ever have to worry about it.So I tried this yesterday and it did look right, the color that is. But my TV did but turn on the HDR logo. Am I supposed to do it manually within windows for Emby theater? Link to comment Share on other sites More sharing options...

But you'll want to update mpv. I can help you with that. You can take a look at this, to have a better idea. https://emby.media/community/index.php?/topic/69872-hdr-tone-mapping-with-mpv/page-1 Edited March 12, 2019 by Doofus Link to comment Share on other sites More sharing options...

If I want to sit down and watch a movie I may fire it up but mostly use the Shield. I have messed with Emby Theater a bit and like what I see, much more options under video. So what I understand you to be saying with mpv doing the tone mapping is I am still getting the same (similar) image, its just being processed at a different stage?

It has many more options other than what is on the UI. Correct. The 'standard' way HDR is handled is the information is sent to the display and the display does the tone mapping based on that information. So instead of doing that, mpv has it's own algorithms to apply the color. I'm very active in testing all the options, and I try to post what I think are the best options. At this point, I actually prefer what mpv does, when compared to passing the metadata. I can help with whatever you'd like to do in Theater.

My 4k drive and some discs show up Thursday, so I will start playing around at that point. Link to comment Share on other sites More sharing options...
schmitty 61 Posted March 13, 2019 Share Posted March 13, 2019 So... I’m guessing by this, that if I was to rip a 2160p disc, and import it to my library... Emby won’t simply transcode down to 1080p on those devices. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

But if you use an HTPC with theater desktop, the player handles everything you need. Edited March 13, 2019 by Doofus Link to comment Share on other sites More sharing options...
