Garyindiana2 yes, we are aware of this and are working on making it work with higher resolutions 
Apple Vision Pro Fail

rabbit_bird Hi! Apple's spatial videos are interesting. Strictly speaking, it looks like these videos are captured at 30 FPS using 2200x2200 resolution with an FOV of 71.5 deg. That resolution is better than it sounds because it's projected onto a narrow FOV. When you toggle the immersive mode, that narrow FOV allows Apple to blend in the pass-through environment, which may be why some people "say they appear more immersive." The SBS files offered for comparison have been converted to the SBS format with 30 FPS using 3840x1920 resolution. That doesn't seem right to me. I think the resolution of the SBS should be 4400x2200. However, a typical SBS video player is going to stretch that 71.5 deg. FOV to 180 degrees, and it doesn't look good. Overall, I don't think you can compare "Shot on Vision Pro" to the jaw dropping 60 fps / 8192x4096 / 180 deg SBS productions available from the modern studios.

GfLm I've been reading lots of review on Reddit from people hyping the spatial videos, claiming it makes them feel emotional and feeling they are reliving the moment. I guess these people are new to VR and have never seen an 8k 3d SLR video before. However, even the 8k 3d SLR videos don't provide the sense of emotion or reliving the moment, which makes me wonder whether the high resolution and OLED screen of the AVP, and viewing the video in a narrow POV blended in with the high quality real world passthrough is what provides this effect. Either way I intend to purchase one purely for watching porn and movies. Unfortunately I live in Europe will have to wait until later this year but I've never been more hyped and cannot wait for this to arrive.
rabbit_bird Apple has a lot of work to do on the Vision Pro (AVP). See MKBHD's latest YT for example. At the moment, we're just barely able to watch VR porn on the AVP.
I'm copying the large VR files to the AVP. Then, I'm using the free Moon Player for playback (slightly less bad compared to the paid Reality Player). The nicest thing you can say about both of these apps is they are "working prototypes". And that's really all we needed them to be for now. I have faith that, given time, world class developers will bring advanced video players to the Vision Pro.
Anyway, that Moon Player handles frame rates better, but randomly crashes during playback, and leaves an annoying overlay in the immersive space. You can move the overlay around, out of the way, but the funny thing is that the overlay acts as the spatial audio reference point. So wherever you move it, that's where the spatial audio sounds like it's coming from. It's pretty obvious these developer(s) have no idea (yet) what they are doing.
As far as "the sense of emotion or reliving the moment," I would say that playing back your own VR recordings is quite literally the only way you can relive the moment. You can't really relive the moment if you didn't experience it in the first place. If we talk instead, about the quality of immersion when viewing state-of-the-art professionally produced 7K-8K 3D porn videos, then I'm blown away by the difference between my old Quest Pro and the AVP.
It must be said that a lot of the content on SLR isn't state-of-the-art. Cameras keep getting better, and the production quality of some studios is way better. I've been loving the latest content from a studio that no longer publishes on SLR. I won't advertise for them here on SLR's forum, but they produce immersive hardcore BDSM. When their shots go in for a close up, my eyes don't see anything but the performer, and (now that I'm comfortable wearing the AVP) my brain stops translating and I'm in the moment and it's beautiful.
Glad to hear you're enjoying it so far. I cannot wait to get my hands on one of these.
rabbit_bird I don't know how actually spatial video looks like, but when I watch reviews and they show it off I just don't get it, a 2d 3d square video with blurr or not around the video? I'm watching just thinking wouldn't vr 180 video be better? Idk 
I still haven't seen spatial video in the quest 3 yet. They say samples are coming.
GfLm any chance you’d be able to post (or otherwise send) one of the videos you were able to convert to be able to play in high quality on AVP? That method you figured out is far beyond my level of tech knowledge and would really like to see how it looks in high quality. Stuck on 1080p over here!
Did anyone already try to start DeoVR via ALVR? I read that ALVR is starting to get really good.

Garyindiana2 It turns out a lot of the original files, available on the downloads tab of each video in SLR (see figure below), are not encoded with the "hev1" codec/tag. For example, see Best Massage Ever Pt.1.
I can share some more thoughts on this, hopefully it's not too technical. These original files are larger because they use a higher bitrate, and in some cases, the studios are still using an older Apple friendly h.264 codec (instead of the newer h.265 codec). The newer h.265 is often Apple friendly, just not when using the "hev1" variant. Apple devices like the "hvc1" tag. For streaming, SLR re-encodes everything to the most advanced compression, but this isn't necessary if you have a fast connection, and are downloading to watch on the Vision Pro. Note that the video I linked above isn't even 7k or 8k, but nevertheless when watching on the Vision Pro, the quality is stunning.
Figure: Downloads tab with original h.264 download highlighted
What I've found is that the original files for studios that publish up to and including 7k, see for example SinsVR, are usually fine without needing to be remuxed. In other words, the original files are not encoded with "hev1". However, it looks like the trend with most 8k publications is to use the "hev1" codec, so don't be surprised if you have trouble with some of the 8k downloads.
GfLm Great info. Is it just the 8K videos where this is an issue? Having the "hev1" codec.
avpOrbust Unfortunately, no. I have found that the 7k videos from some studios are using the "hev1" encoding. It's silly that Apple doesn't support hev1. Apparently, there's an explanation from Apple for why they think "hvc1" is better than "hev1" somewhere in the Apple developer documentation. As someone else already stated here, it's usually up to the player app to handle as many codecs as possible. Everything SLR re-encodes to h.265 seems to use the "hev1" encoding. They've talked about how much re-encoding they do here on the forums. Lower bitrates, highest compression, best streaming experience, etc.
GfLm Thanks for the info, I got a few to work.
The Moon app doesn't seem to play 180VR correctly. You can do 360VR, but then it isn't 3D. Also, can confirm that the stupid grab bar to move a window in AVP is there as someone else mentioned, and if you move it, the sound moves with it. Which is as designed for a non-immersive situation, but definitely not correct when you're in immersive VR mode.
The other annoying thing watching VR in AVP is the down arrow thing that appears when you look up, but in VR immersion it can show up even at regular eye level. There's got to be a way to hide that UI element when you're in an immersive video. Might have to try building my own app...
This whole story is so typically apple. Polish the shit out of a device but only for the things they think are important. Still, a very cool headset though.
The AmazeVR concert app on AVP really shows the potential of what the future holds. The immersion is amazing.
avpOrbust Don't get me started, these developers have zero talent and can't fix the most basic bugs. Besides the random crashes, the two most obvious Moon Player bugs are the grab bar, as mentioned, and the scenario where after playing a video in 180 mode, the next time a video starts, you have to first choose flat mode (even though the player opened in flat mode), and then choose the 180 mode. Otherwise, you end up with the flat mode screen staying visible, or the immersive mode simply not starting. Now, I don't know why they can't hide the fucking grab bar. It should only reappear (with the playback controls) whenever you pinch into space. As for the other issue, they've clearly gone and used a global variable to track the selected mode. They fail to reinitialized the variable when a new video starts. But the player doesn't want to launch in immersive mode, even if immersive mode was last to play. You can't go straight for the 180 mode toggle, or else there's no 'value changed' event, so you have to choose flat mode first, to sync the actual state with the tracked state, and then choose the 180 mode.

Let's hope that planning works out indeed.

Since the update to get rid of the jittery laser pointers for hand controls, the play button doesn't seem to respond to the finger tap gesture on the deovr or SLR websites. Everything else in the UI seems to respond to the finger tap...changing resolution, volume control, exiting, etc. Just the play button doesn't work.
a month later
@Kieshi any update on this?
