Passthrough & Greenscreen

Sandi_SLR

Hey guys, we will be introducing a "new" format for greenscreen videos soon.

Since we can't have videos with alpha channel, we decided to pack the alpha around the fisheye circles.

And the results are great, no more chroma key deleting all the fine hairs and no more green spill on the actress!

Of course we wont forget about non-SLR studios, we will write up a guide for anyone to do this, maybe a tool to do it with ffmpeg (its quite easy to do it with any postprocessing app anyway). All they need need to prepare is an alpha map next to original video.

Subsequently this also solves the issue some had with pure green BG on our greenscreen releases, since, as you can see, the original file will be spill suppressed (no green) from the get go, so it would make watching it without passthrough much more enjoyable.

Will keep you updated how it goes 😉

Sandi_SLR Is this available to try now?

doublevr

Sandi_SLR that's the best thing I've seen in a while 🔥
Definitely level up of what we have

Sandi_SLR Very cool idea, love it, use those useless pixels, why not

LordCrash

Ok then, and what about that green body suit you invented in the latest passthrough scene?

How do you want to fix that for those not interested in (or capable of displaying) passthrough

The scene with Dora is practically unwatchable without passthrough. Huge bummer.

Sandi_SLR

thatthotok Not yet, we made a proof of concept with developers and wanted to share the excitement.
We will try to get it into release as soon as possible.

LordCrash Hey, I am here to offer technical solutions where I can. Originals are not my domain, but I will say we are witnessing an experimental period, where users will vote with view time and likes. Will it stick? No idea...

Sandi_SLR
Don't get me wrong, your effort is very much appreciated. It's just so disappointing that you actually wanted to help and that you actually came up with a possible solution only for the guys in production to ruin it right away with their next scene.

And I don't see the option to downvote something. I have no idea how likes alone should be an actual good measurement for public appeal.

Anyway, like I said multiple times before, experimental scenes shouldn't get in the way of the final product people are actually paying for. If that only was for experimenting you could easily shoot some test footage with girls after regular scenes (or before) like "Hey girl, before we start with the actual VR scene, let's just shoot a few minutes in front of a greenscreen. We'd like to take the footage for our innovation centre and feedback loops in order to make passthrough stuff better and somewhat market-ready in a few months or years".

Please keep experimenting with passthrough. I love the feature and the only way to perfect something is to keep trying. I don't mind being a lab rat.

Nailed it again.

LordCrash Agree! Experiments don’t have to impact the main content until it’s ready. It really is a shame to miss opportunities to make potentially great scenes with great casts with these experiments. The experiments should be bonus content, not trying to replace the main content before it’s perfected. It doesn’t make sense the way it’s currently happening. Calling this an experimental phase is really just an excuse for failing. SLR should be focused on what it knows how to do, release that content and experiment on the side, not failing front and center.

LordCrash I have no idea how likes alone should be an actual good measurement for public appeal.

Just talking generally here: my understanding is that there is a direct correlation between the amount of likes a scene receives and its general popularity in terms of downloads/time streamed/usage in playlists/etc. etc. etc.

I've seen a lot of seemingly credible theories about how likes/favorites could be misleading due to A, B, or C, which all could certainly (and probably do) factor in. But at the end of the day the data doesn't lie, and the data says that "likes" are far and away the best predictor of overall popularity.

Sandi_SLR

LordCrash This scene was shot way before I started working on this problem. I can agree with @justsomedude101 that likes and watch time are quite related. The only thing I can influence is to bother post production to do a better job, for producers decisions you will have to voice, as you did, it in thread like this one https://forum.sexlikereal.com/d/3506-can-we-please-get-non-greenscreen-versions
You can also try a poll asking people do they like it, undecided, or dislike?

argyle43

justsomedude101 so stick in a dislike button to see how far the likes go down then. I’m betting dislikes outweigh likes by a factor of at least two.

or just ignore this and continue to pretend that “data science” is a standard practice at SLR.

People have said multiple times over that the like button is often used to add to favorites as a sort of "watch later" button, and just because someone watches something doesn't mean they enjoyed it, it just means they watched it. I've watched all the passthrough videos that have dropped so far, even though I hated pretty much every one of them, just to see if something improved.

LordCrash

justsomedude101
There can be stuff that is even more hated than loved. If you only count the positives you'll never find out.

Reality is that most people are simply indifferent to a lot of scenes and don't bother to giving a like at all.

Sandi_SLR

One thing I will add, that we are still actively working on a solution for converting normal videos into passthrough. When we figure it out, there will be no need (or discouraged) to shoot on greenscreen... This should end the experimentation period.

spacepirate

Sandi_SLR experimentation period

fyi we are not lab rats. we are customers who are paying for quality content.. not unwatchable experiments

LordCrash

Sandi_SLR I'd really wish this was true but reality is that it's not only about passthrough but also about positions etc. The latest passthrough scene with Dora only offered positions with you liying on your back.

I don't see how it should make people happy if future scenes with real VR settings were limited to certain positions simply so to that some people could use it with passthrough while liying on their bed.

Like I said before, two different customer bases with different expecations. Apples and oranges.

Lenovo

Sandi_SLR Stick to it man,many people have misunderstanding towards passthrough function because quest 2 passthrough does not work well or they don't even have access to it .When colorful passthrough get mature and pervasive, they will beg for it like begging scripts.

I found this on deo, it looks like it from a non green screen video converted into a green screen but it's got alpha and it looked pretty good 👍

Got me thinking, WOW 🤯 this pass-through bout to get even better, in quality 👍🥂

Sandi_SLR

spacepirate If you track back to what I said (experimental period) you will see it was my personal opinion, not an official statement.

mebejoe

spacepirate fyi we are not lab rats. we are customers who are paying for quality content.. not unwatchable experiments

I don't mind a few unwatchable experiments mixed in with all the great content.

I love the passthrough feature and I'm glad to be a test rat as they roll it out.

alina

Wow, lord personally think you should cut Sandi some slack! Sandi was just sharing some potential improvements behind the scenes for pass through. Although I agree that sometimes content gets wasted but I make that case a shit ton of scenes. Milfvr for example has a shit ton of great scenes but the fact the footage is low resolution completely kills the experience for me. Or those videos where the camera they use makes all the models small. The ratio kills the immersion, or when cameras are not centered for blowjob or cowgirl scenes. All these in my opinion also ruin a perfectly good scene. Sandi experiments on one scene that was a studio decision and you bite their head off. Without experimentation their will never be growth or improvements. On side note do you even have a vr headset that is capable of pass through? Have you tried it ? Or do you just hate pass through in general based on your reaction? Give Sandi a break! Keep up the great work Sandi, I know I and others appreciate it!

LordCrash

alina What the heck are you talking about? Read all my posts before replying, I never attacked Sandi in the first place...

dudu32

can this method work with flat screen scenes too ? and like add depth and 3d to it ? and put in sbs mode if wish ?

how this method work ? or is this method just for make it easier and better accurate to cut out background on any vr scene and play in passthrough ?
or im on wrong path and misunderstand ?

would like to see a probe of this and figure out how it works...rly interesting looking stuff you do here guys...

Sandi_SLR

dudu32 Hey, this is merely to carry info on which pixels are see through. So BG removal, baked into the video, then it doesn't need to be computed on headset, so not only the result being much better, we won't loose any fps.

So same as you have alpha channel with images, we mimic this by adding the alpha channel around the fisheyes, since we can't have it included in the pixel itself.

Mutiny

Sandi_SLR It just clicked for me how utterly brilliant this solution is. You're basically smuggling the alpha channel in the trunk of the car. Genius.
