A bit of an update:
With the most recent set of keys, I was able to rip the US version of Ender's Game in 4K. There were two streams on the disc, once I installed Java to remedy an error from MakeMKV, I discovered that one of the streams was labeled HDR and the other No HDR. I ripped them both, but I don't have any way of telling if there is a difference. They both look the same on my non-HDR 1080 monitor. I did, however, notice that the UHD rip has slightly more vibrant colors than the regular Blu-ray rip. I'm guessing this is a byproduct of the recoloring process used to upgrade these movies to HDR.
Downsizing 4K Rips
I have discovered a strange issues when trying to reduce the size of the 4K rips (for smoother playback on devices that don't have a dedicated GPU, for native playback on Xbox One S without the Disc (it didn't like the MKV file), and to satisfy my own curiosity about my Surface Book screen
). I've run both Ender's Game and The Martian (the only 4K discs I've been able to successfully rip) through various video conversion software and the resulting files have colors that are dramatically different from those of the original file and the 1080 rip. It is almost as if the blue color has been cranked way up, everything looks grey/blue and the colors don't have any pop. This happens in Handbrake, with various settings (I'm having another problem with Handbrake involving the kbps settings, but that is probably due to my lack of knowledge with the software), in Acrok Ultimate Video Converter (which used to be my favorite way to rip blu-rays before the results became inconsistent), and with Shana Encoder. Here is where things get interesting, I also used Shana Encoder to remux the file from MKV to MP4, the resulting file had the correct colors. Trying to reduce the remuxed MP4 has the same result in Shana and Acrok, color change. I'm wondering if this has something to do with HDR, but given the fact that it remuxed just fine, I'm not so sure.
The reason I wanted to remux the file in the first place was to give it to my brother who has Adobe Premier (which has no support for MKV files) to see if a non-open-source (Handbrake), not cheap (Acrok) video converter could convert the file without messing up the colors. I will report back on the results of that experiment when it is completed.
If anyone has any thoughts on why the color is doing this, let me know. Also, if you have questions, feel free to ask.
