i came to a discovery on why video looks worse on the index or reverb than the cv1

i havent seen the index or reverb, but i have read this post by runesr2;


"
Watched a few movies using BigScreen Revive with Index res 200%, (=
solid 90 fps) and it's close to being in a theater. But one movie was
mkv another mp4, although 1080p it's just not good enough. You need 4K.
But
that's just me, I'm sure many persons with little knowledge about VR
would be totally blown away. With 4K and virtual surround sound I think
Index might be really close to IMAX at home
"

i decided to tell him in that thread that he probably wasn't using the settings i use for the cv1 to watch video, and i forgot my settings for watching videos, so i dusted off my cv1 and set it up and installed the software etc and got this fine picture of my virtual desktop settings for watching videos;

f7fpd1nr4u85.jpg


i watched a few videos and saw a artifact i hadn't noticed before, as a benefit of the cv1 screen-door effect. by there being a screen-door effect, the eye making the image more clear in the one spot looked at while blurry the other areas, you don't see the screen-door effect uniformly.

this adds a depth factor to the image, seeing the screen-door effect lines acts to add in detail that isn't there in the actual video frame. and that SDE isn't in the index or reverb, at least not to the level it is in the cv1.

therefore i deduced watching the same video in the index or reverb without the cv1 SDE quality would lack some depth in the image that the cv1 has. if you  had the eye tracking blur some of the video you might have the same effect but you might not, hard to say.

of note is the fact i often use negativescreen to produce visual effects in my video,s sometimes, so i know a beneficial video artifact looks like when i see one. the SDE adds in a lot of tiny effects that are attractive, using my virtual desktop settings above and in full screen video watching 1080p video, in the cv1.

but the cv1 is still a bit tight near my right cheek bone under my eye so i cant wear the cv1 for too long. i would like the cv2 to have a nice padding on the bones under the eye please...

I wonder is the point he is driving at that SDE makes the image look sharper? 



Maybe - if you constantly micro-shake your head to get rid of the SDE  B)

That's in theory, in the real world I don't see CV1 ss 2.0 having a chance against Index res 200%. And Reverb is king, unless you care more for the fov.

@Calibos - You need to watch 4k video content on the HP Reverb when you get it. You will see the biggest difference playing 4k video imo.

I feel like I am repeating myself here but you are restricted by the source resolution. This is why Adult VR producers as an example are producing content above 4K to get better quality.

What do you mean? All I'm saying is 4k video looks a lot better then 1080p on my HP Reverb. Well it does to me should I say.

How can you be restricted by the source resolution when only now with the 2160x2160 per eye Reverb is there a HMD that has enough resolution and Pixels per degree to just about replicate 1080p on a Virtual screen that fills the horizontal FOV of the HMD and about 2/3rds of the Vertical FOV.

Using 4K source material which is downsampled to the effective 1920x1080 virtual screen possibly improving the image quality like Supersampling does for our VR games which are then downsampled and warped by the SDK to the HMD native resolution. Thats another question entirely. It may well be valid. But thats not what it sounds like you are talking about. The way you are phrasing it talking about the source restricting things makes it sound like you think the Virtual Screen could be made up of 4K's worth of pixels and thus we should be feeding it 4K source material. The overall resolution of the Reverb panels might be 4.5K's worth of pixels but the VIrtual Screen with its width filling the Horizontal FOV will fill not much more than half the Vertical FOV. Half of 2160 is 1080. ie. an effective 1080p Virtual Screen. Putting the possible Super/Down-Sampling interpretation/benefits of 4K down to 1080p aside, it seems like a waste of time to feed in a 4K source thats going to display on the virtual screen with a max of 1920x1080 pixels anyway. Obviously if you have the media in 4K format anyway then it can't hurt but I remain to be convinced that theres any necessity for me to go and re-source all my media in 4K and buy a load of new Hard Drives to accommodate them.

VR Porn is recorded in 4K-6K now because that captured res is split Horizontally in 2 for the SBS 3D and then spread across 180º Horizontal and Vertical Capture FOV. You can never see more than 100º Horizontal or Vertical at any one time because thats the FOV of most of the HMD's used to view the content. You arent seeing 4K image quality porn when the file is 4K. If the vertical capture res is 2160 pixels spread across a captured 180º vertical FOV and the HMD lets you see 100º vertical then you are seeing an effective 1080-1200p quality.

Anyone remember the early videos that were recorded in 4K 3D 360. 4K split in 2 for SBS 3D and then half the res that was left wasted on 180º behind the viewer/camera. Who the hell watches a VR Porn Video and admires the couch or the curtains in the room behind them!! 4K spread that thinly was pure pixelated mush!! They quickly realised that 3D 180º capture was they way forwards for VR Porn where 40-50º either side and above and below of 'The Action' was enough for immersion without wasting a ton of capture res where you would never be looking anyway.

3D 180º VR porn captured at 4-6k nowadays in order to deliver an effective 1080-1200p to our eyes. Back in the early VR porn days with 3D 360º 4K content was delivering an effective 240-360p to our eyes.

Ya know what, I haven't even tried watching bluerays or 3D movies in virtual desktop. I've not even used virtual desktop in over a year. So you guys have convinced me I need to try all of this so I'm going to give it a shot tonight.

If I stick a blueray in my PC blueray player will virtual desktop play it? 

Or do you have to convert your bluerays to MKV Format first and then play your movie files from your desktop?

Thanks for any help given.

If you have software that can play the Blurays on your PC already then I don't see a problem. Virtual Desktop will just display your PC's desktop and any active or fullscreened apps on the Virtual Screen as if it was your real monitor. So anything you can do or play on your real monitor you can do and play on the Virtual Screen.

I am using the HighMax Virtual Cinema DLC. Accurate recreation of the largest iMAX in the world at Darling Harbour Sydney Australia. I rip all my content, store it on a Media server and play it back on my PC with KODI. Fullscreened KODI on the Virtual Cinema Screen works as it would on a real monitor.

If you are using an Ultrawide 21:9 ratio real life monitor then I recommend you switch it to a 16:9 resolution of 1920x1080 or 2560x1440 etc otherwise you end up with a situation where watching 16:9 content has black bars left and right and top and bottom of the Virtual screen wasting resolution. This is because Virtual Desktop and all similar VR apps will take the 16:9 content displaying with black bars left and right of your 21:9 monitor res and fit that within the 16:9 ratio Virtual Screens and as you know 21:9 displayed within a taller 16;9 ratio screen will have black bars top and bottom. Whereas if you switch your real Monitor res to 16:9 before starting Virtual Desktop then 16:9 content and 21;9 cinemascope  content will display properly on the 16;9 Virtual screen (ie. 16:9 content will fill the Virtual screen completely and Cinemascope content will fill the full screen width and have black bars top and bottom as it should.)

Got my Reverb set up tonight.

Holy FCUK !! Virtual Cinema Heaven. Just wish they'd fix the mild Chromatic aberration.

Watched Endgame 3D again. I don't know if tears were streaming down my face for the Ironman Death Scene again or if it was tears of Joy having just seen Endgame in the largest iMAX in the world in 3D with a stunning image quality/res.

Given the subject of this thread and the posts therein, I'll reserve judgement if this is the best its capable of. Its already amazing but Shadowmask/Rune might well be correct about a 4K source being downsampled adds clarity if thats what they were getting at. I couldn't find anything I had in both 3D and 2D 1080p to compare. The SBS split of horizontal source res 1920/2=960 could be compromising things just from watching in 3D...and like I said, it still looked amazing. So tonight to rule out the 3D complication I am going to watch The Mandalorian S01E04 in 1080p 2D and 4K 2D to compare. 

I'm telling ye lads, in 2023 when we hopefully have our 4000x4000 pixel per eye, eyetracking with Foveated Rendering, auto IPD physical calibration, variable focus, 150º+ FOV, Inside/Out tracked, Wireless, Hand Tracking, Face Tracking, Full Body tracking Rift/Quest 2.0 AIO (All-In-One) for €399-€499 that runs on a potato GPU thanks to ET&FR....THATS.....when VR takes off Big-Time. There will no longer be any excuse not to own a VR HMD. Even if none of the naysayers ever played an actual VR game, every PC and Console gamer on the planet would want one even if just for Virtual Cinema, VR Porn and playing their Monitor games on their own private 4K 120hz 10ft Virtual screen that cost them €399 instead of €3,999.

I got my first small taste of part of the future of VR tonight and it was Glorious.

Wow the Reverb does all that? Perhaps I should re-think getting one...
