    yes but convert it properly.
    it was given to me as a MKV file. 1 of 7 setups in my house can play this properly using ... the oppo 203 or shield tv.
    the rest are 1080p sets and a good 3d setup is required in 2 of those meaning i'm not giving up on 1080p just yet.
    and i want this video to be compatible with 1080p bluray.
    i think it needs to adjust the color when converting from hdr. it is not doing it right.

    what tools exist to downconvert from hevc hdr 4k to h.264 sdr 1080p???

    Have you tried RipBot?
    I'm using it for converting HDR MKV 2160p to SDR MKV 1080p.

    Or probably better, CloneBD.

    Ah, indeed, overlooked that part. But i'm not sure i think @DrinkLyeAndDie requested that and think they responded they placed or might place it on the todo list?

    I probably expressed interest at some point. I never officially sent an email or anything, however. I'd definitely love to see support for MKV as the source.

    Ill be releasing a video how to take a uhd rip and convert it to 1 to 1 h264 8bit with ffmpeg script and it will look exactly like madvrs pixel shader nit value with the exact peak brightness and luma. I created an advanced hdr to sdr lut that works on all hdr movies and produced 0 banding and matches the color of the hdr to 99 percent accuracy with bt709 8bit. I choose to use 18mbit as a test file but could up it to 20-25mbit and the sizes of the h264 actually match the h265 is size in my tests. A 1 min clip takes approx. 8 minutes to encode with the 3d lut I used. Not many people know how to do this so I will make instructional video if this is something you want to do. Basically take any h265 hdr video and covert it to hdr to sdr bt709 8 bit with no loss or banding. The hd audio and atmos remain untouched. with ffmpeg the first extraction is from 300 meg to 5 gig to act as the main video file to add the lut. I use the proxie file of 200meg to apply the lut them go online with the huge file and encode. its simple but you must use proxies or your computer will freeze with an h264 uncompressed source file. If you use a crf of 16 or less you risk reducing the encode quality from the original. The idea is to use raw files off uhd and work with proxies then apply the raw file in the end with the hdr sdr lut and add the audio in mkvtoolnix last back into an mkv container. IT keeps the sinc and the video will play on any normal bluray player or stream box but retain the color and shading of the hdr material on sdr boxes and tvs. Madvr is not needed if you want to get away from the pc. I use madvr but everyone is different.

    that is what i'm looking for ... a detailed step by step way to do this...
    including a simple test to verify tools are installed properly, like ffmpeg.
    when will this be ready?

    Once my 2 testers confirm perfect color transfers. Couple weeks.
