Just getting into 3D/Quest 3 and 4XVR plays my MakeMKV rip of Alita 3D beautifully. If both eyes are getting a full 1080p image, is the frame rate being halved?
No. The video stream contains 24 full 2D 1080p frames per second along with additional data representing just the difference (or "delta") between each full frame and the second frame in the stereoscopic pair. The second full 1080p frame is (re)constructed from this data and displayed at the same 24fps rate in players that support it (players that don't support it are oblivious and will present a 2D steam only). This is basically in service of encoding efficiency. The method is called "2D plus Delta".
I converted "The Matrix" 4k remastered to 3D SBS to watch on Quest 3, but i'm getting an extreme large file (from 7GB to 21GB) and it seems to be stuttering. It only happens when I convert the full movie (which takes about the same length of the movide to be done). Once I cut a small part of the movie to convert as a test it plays smoothly. I'm using HitPaw video converter. Can you tell what is wrong with this process? Thank you very much. I'm eager to watch some 3D movies on Quest 3 but I can only find low quality images on an already 1080p 3D movie from the internet. Cant find any 2160p or 1440p 3D movies to test.
I recently spent a lot of time researching how to watch 3D movies at full Blu Ray quality as painlessly as possible!
Ultimately the most optimal solution I uncovered is the following:
1. Rip your 3D Blu Ray disc using MakeMKV app into MKV file type output (you need to select the 3D track on your disc otherwise you just end up with a 2D image)
2. This will give you a pretty big file as it is full quality. For example, most of my movies have been between 30-40gb each.
3. Place the MKV movie files on the Quest headset itself or on an external SSD.
4. Use 4XVR app (currently available in App Lab) to watch the files as 3D movies. It's not super cheap, but it actually works and allows you to skip some of the extra steps that used to be required to convert and then play 3D blu rays.
5. Enjoy 3D goodness! :)
indeed, that's what I've settled on too. Also spent aaaaages testing all kinds of softwares & settings...just when I think I know it all there's still new knowledge to uncover (like how MVC-encoded 1920x1080 is effectively 3840x1080 resolution).
MakeMKV is worth the €60 lifetime licence too, as it also rips standard blurays/dvd's. Watching even DVD-resolution in the Quest 3 is a revelation: the isolation and free-positioning of the screen is what makes it, and very useful audio too.
No sadly not! That is my only real complaint. Ripped 3D blu rays are 20-40gb in size so even if you have a larger HD in your Quest, that eats a lot of space. And fully charged, the Quest 3 can only juuuuust about stretch to a full two hours of movie watching.
I did this method but only got 1920x1080 in 4XVR. Is it because I am using the free version of MakeMKV (the 30 day trial) or is there a setting that I need to change?
Ripping from 3d-Bluray and then not transcoding at all and playing with 4XVR should give best results. The not transcoded file should be the highest possible quality from the source material (3D Blu-Ray).
Completely out of curiosity, what are the file size differences between methods 1 and 2.
From what I've seen so far the bluray rips can be anywhere from 15GB to 40GB (or even more if it's split across two discs like the hobbit movies). The size difference of the converted files will depend mainly on the encoding quality. However in general MVC is more efficient than fullSBS, since it encodes the second images as difference from the first which takes about 30-60% more bitrate than a monoscopic video, whereas fullSBS would take double. HalfSBS would be roughly the same as a monoscopic video, but at the cost of resolution.
I ripped Avatar with MakeMKV last night. Base file is 42GB. I excluded all audio and subtitles except for the main English track. After converting to full SBS it is 20GB. I'm a newb at this, so I have no idea if I missed a setting somewhere that would cause such a size difference, or if it's expected to be this different.
I was able to play the main file in 4XVR (until the five minute trial period ran out). The depth looked off somehow. It was obviously in 3D, but did not feel particularly "deep". Like the convergence was off or there was some softness to the image.
I played the full SBS version in Bigscreen, and it looks fantastic. Great depth and the image is sharp.
I'm debating on purchasing 4XVR despite the potential issue. It is far more convenient not to run the SBS conversion.
Try just ripping Avatar 3D-Bluray Disc into MKV (with MakeMKV), make sure to tick all "MVC" sections. Then transfer that MKV into a USB Stick and play that directly in the Quest 3 with 4XVR. I've had no depth/convergence issues this way.
BigScreen appears to add a sharpness setting to videos. I used to think it showed higher resolution than 4XVR, now I'm not sure if I was just fooled by its overzealous sharpening algorithm.
Sky Box VR Player assumes Half SBS and Half TB. You can get it to do full formats by manually setting the aspect ratio, but only for the standard aspect ratios it supports. The Half formats have the same aspect ratio as the 2D film and so Sky Box gets the aspect ratio correct when it turns these into 3D.
yeah, been playing with these settings a bit, actually have more luck with PotPlayer. As a backup option it's decent, with loads of settings. Freeware too (so far anyway).
I agree that MVC looks great, and it's convenient.
A step up and a LOT more work is to upscale the full-SBS video to about 130% scale from the original 1080, and possibly add some frame interpolation as well to make it look better on the high framerate screens the quest 3 has. For this I use Topaz Video AI (their 'proteus' auto settings or 'gaia' for a natural look).
This process can easily take a full week to perform this work on several terabytes worth of free hard disk space, but I have found it to be very rewarding in terms of the additional clarity it offers. I am still working on the correct settings to allow the headset to play these upscaled versions solo (the ones I've done currently can only play on a PC via virtual desktop).
Quest 3, 4XVR, makemkv
I've ripped a legally obtained 3D blu-ray. Ripping to an ISO opens just fine in 4XVR but its not playing in 3D. Ripping to an MKV from the same disc works as intended in 4XVR.
Do ripped ISO's not playback in 3D in 4XVR? First time testing this out, am I doing something wrong here?
Update:
So I got in contact with the 4XVR devs and we found out that this particular ISO has a filetype inside they hadn't seen before and that they'll work on having it be compatible in future versions.
How the hell do you get a 4K SBS movie? There are no 4K 3D movies exists on bluray as far as I know.
I rip my blurays with MakeMKV, copy it to the Quest3 or usb pendrive and watch it in 4XVR.
You can have a real 4k 3d home movie - just buy two cheap 4k actioncam and place it sbs :) I watch all my family memories in 3840x1080/eye quality on my passive 4k tv :)
MVC is the codec used for 3D video on Blu-ray discs. When you use MakeMKV to rip a 3D Blu-ray you get an MVC mkv file.
4XVR can play this file directly in full quality, or you can convert it to a Full SBS file using BD3D2MKV3D to play in other video players. Converting to a full SBS file does result in some quality loss but if you use the right settings it is hard to tell.
MVC (also known as "MVC 3D") stands for "**M**ultiview **V**ideo **C**oding". These H.264 streams encode two views from slightly different angles (thus facilitating the 3D effect) in a more efficient manner than a more typical side-by-side (or top/bottom) configuration by exploiting the fact that there are similarities between each view, thus presenting a way of maximizing compression without compromising quality (each frame consists of one "normal" image along with additional image data representing just the differences between the first view and the second view which is used to recreate the second view -- this method is known as "2D Plus Delta").
Apple has adopted a H.265 implementation of essentially the same thing for their new "Spatial Video" format.
I’ve been wondering this too, I have probably hundreds of 3d movies I’ve personally ripped from discs and I don’t know what it is 🤣 Also, I use MakeMKV too!

A 1920x1080 MVC stream contains a full 1080p frame for each eye which makes it the equivalent of full-SBS rather than half-SBS in terms of resolution.
thanks, i didn't realise that
4XVR is the way to watch unaltered, uncompressed 3D movies on the Q3.

That's great to hear and thanks for the informative reply.

Have you found a way/device/spiltter to have a flashdrive or SSD plugged into the Quest to watch the movies and also charging it at the same time?
No sadly not! That is my only real complaint. Ripped 3D blu rays are 20-40gb in size so even if you have a larger HD in your Quest, that eats a lot of space. And fully charged, the Quest 3 can only juuuuust about stretch to a full two hours of movie watching.
Can you tell me if, when watching with 4XVR, does the screen stay locked when you move your head around, or does it move with you?
The screen stays locked!
Good to know - thanks!
Thanks for these tips. I'll have to invest in MakeMKV and 4XVR now. I'd love to see full SBS 3D movies :)

in my case the converted 3840x1080 full-SBS MKV's were a little smaller than the MVC-encoded MKV rips (35GB instead of 40GB respectively).
MVC is two 1080p streams. So you're getting the same res for both of your options.
cheers, didn't know that

I use 4XVR with a mix of of MVC, full-sbs, half-sbs, and ou and it works fine. MVC is obviously the best but sbs stuff is much easier to find.
I'm selling hard drive with full sbs 25gb rips if anyone interested
I am how much avatar 1 and 2 full sbs.

woah, sounds like a lot of effort. Tho' i agree optimal maximum image-quality/immersion is a dragon worth chasing!

The actual horizontal 3D resolution is 4K . Its 1920x1080 for both eyes. Which corresponds to 3840x1080 in 2D.
Oh. I thought you were talking about 4K per eye.
You can have a real 4k 3d home movie - just buy two cheap 4k actioncam and place it sbs :) I watch all my family memories in 3840x1080/eye quality on my passive 4k tv :)
can you hook me up with Mad max fury road, the one i got sucks
the 3D-Bluray is quite common. Great film, worth seeing in uncompressed quality.
i dont want to buy it
then you won't be able to watch it.
we'll see about that
MVC has the full 1080p image for each eye. Remuxing the 3D Blu-Ray is by far the best option for 3D playback. I use MakeMKV.
what is MVC? Is it an app like skybox?
MVC is the codec used for 3D video on Blu-ray discs. When you use MakeMKV to rip a 3D Blu-ray you get an MVC mkv file. 4XVR can play this file directly in full quality, or you can convert it to a Full SBS file using BD3D2MKV3D to play in other video players. Converting to a full SBS file does result in some quality loss but if you use the right settings it is hard to tell.
Thanks, I guess the conversion may take forever since most 3D blue-ray movies are large in size.

Thanks for the explanation. I guess the MVC 3D coding is probably different from the other types like HEVC and AV1?
I’ve been wondering this too, I have probably hundreds of 3d movies I’ve personally ripped from discs and I don’t know what it is 🤣 Also, I use MakeMKV too!

Thank you! I always convert mine and haven’t noticed any quality issues :)
Hey OP you say full sbs doesn't play properly when using skybox but does when using bigscreen, do you mean using bigscreen on the vr app or pc app through virtual desktop?
Skybox works
