I wanted to give some clarification for the latest LTT video about the 3D theater setup regarding the bad image quality they experienced. I hope I can clarify this for people and maybe someone from LTT will even get this info that they can fix their experience.
The reason for the bad result is they made a mistake by re-encoding the 3D Bluray rip using BD3D2MK3D which greatly compresses the quality.
They didn't have to prematurely split the images and re-encode it with BD3D2MK3D in a lossy way and only half the resolution of the already bad quality of 3D Bluray. They didn't have to re-encode at all.
Instead they only needed to use MakeMKV which is lossless and then used Stereoscopic Player (which does support the MVC file) to separate the images. In this way they wouldn't have lost any quality from the 3D Bluray and it would be a bummer after they put in all this effort for this to degrade the quality because of this.
Despite this (starting a general topic) it's sad that 3D Bluray didn't get any spec update such as standard Bluray with 4K Bluray (but understandable due to the questionable decline in 3D interest). So even with the full 3D Bluray quality you only get 1080p, SDR, little storage resulting in low bitrate and 24FPS even though more and more 3D films including the James Cameron collection are mastered in 4K, HDR and most importantly HFR. Especially the 24FPS in 3D are way too choppy, it takes you out of the immersion and can cause headaches/nausea after time.
As long as you're not investing a fortune in a DCI compliant theater or use the Apple Vision Pro, there will be no other way to experience these intended formats other than visiting a commercial theater that supports these formats, preferably IMAX with dual laser system.
But imo the Apple Vision Pro is still the best way to experience these movies. The Vision Pro also enables multi-view now that makes u able to watch the movie together with others.
But I understand that people wanna watch in in the "classical way" by actually seeing your friends and family in the real world and not having their virtual representation in this heavy headset.
So for classical home theaters you can do motion interpolation and 4K/HDR upscaling on your own but obviously it won't be nearly as good and realistic as the commercial grade native format (and this only involves even more complicated steps that people could mess up and actually degrade the quality by incorrect encoding. I would recommend to at least use real time motion smoothing. There are systems that do 4K/HDR/HFR upscaling on the fly such as madVR).
As they corrected in the video they could've used a laser system for projection but the ultimate solution would definitely be a micro-LED wall which even have glasses-free 3D and they aren't even that damn expensive anymore. Micro-LED wall paired with DCI compliance would be the end-game for "classical"/non-VR home theater but DCI of course would be incredibly expensive but this tech really is next level and actually puts you in a different world.
Hope this helps someone.
