  • Alpha Passthrough. How does it work?

Sandi_SLR

Hi 👋

I have a question
I'll use this scene as an example
https://www.sexlikereal.com/scenes/banderas-is-banging-14072

My question is, if they film a scene similar to that how the background looks will they be able to add alpha channel to it and will that help the pass through options work better as we manually set the pt options our selves? Or would yall be able to add a preset alpha setting? Or both lol

And I see previous green screen scenes are gonna get re edited with the alpha

Could yall add an alpha channel to that scene i linked or to any other scenes non green screen.
Was just curious 🤔

      Vrsumo2017 Hey, yes we will be able to convert normal (not greenscreen) videos to passthrough with background removal tricks using AI, this was mentioned a few times and there is a thread about it too.

          Sandi_SLR this was mentioned a few times and there is a thread about it too

          Yes, I remember reading something like that, any idea when these features will be rolling out, for example when will we see a non green screen scene have these alpha channels?

          & Thanks for the reply 👍

            Sandi_SLR and there is a thread about it

            Can I kindly suggest this thread be pinned, I sometimes search for those threads so I can read back what was mentioned about pass through and what is planned, but there's so many discussions.

            Idk, just a suggestion ✌️

              Sandi_SLR Hey, thanks for the answer. However, I mentioned in a previous post that I have already tried that but it didn't work. Just to give you an an overview of this thread, the issue is related to the readability of alpha files when streamed via DLNA. Somehow, DeoVR doesn't recognize these files as alpha passthrough files (even after renaming them).

              For now, we have two potential temporary solutions. The first solution is to directly stream the files from SLR. The second option is to download the file and manually transfer it to the storage of the headset device. So, a permanent fix is still required for the DLNA streaming issue.

                  Sandi_SLR A few months later, have you guys checked what's wrong with playing alpha videos via DLNA?
                  Copying 30-40 GB to my headset is not really a solution or workaround for me, and not something I plan to do often.
                  What's the point of using DLNA then for these types of videos? From my dev point of view, it shouldn't be difficult to debug.

                      Some DLNA servers essentially 'rename' the video went sent over streaming like plex.
                      I believe Kodi doesnt so give that one a try

                          kudirnad Actually, I'm streaming from Windows 11's built-in DLNA server. I'll give Kodi a try. Haven't used it in years LoL 🙂

                            kudirnad I've just tried it with Kodi. Thanks for the suggestion, but it's all the same. I wouldn't say it has anything to do with DLNA itself, but the way DeoVR is handling alpha passthrough streams via DLNA.

                              @Sandi_SLR I have file that has "_alpha" in filename and when viewing directly from local Quest 2 storage, the alpha channel works ok. However when I view the file via URL link on NAS (e.g. http://192.168...), there is no (A) button present to enable alpha channel.

                              Is there something on my side or it is currently not supported?

                                timdey837 That's what I'm also talking about for the whole time. I even somehow got that "A" icon to show up, but enabling and disabling it does literally nothing. From a technical point of view (and being a developer too), I think it's more a case of not taking it as a priority than something that it's very hard or impossible to solve.

                                If I may, one of the workarounds could be creating a temporary file on the headset (not necessarily the size of the original file, but only like 1GB for the video buffering), and then streaming the video as if it was actually stored on the headset. That could work because (to spare me some time when copying 30+GB file), I start copying it with my built-in File Manager in the background, and I'm still able to watch the video without any issue whatsoever (but I still have to have 30GB of free space).

                                Just my 2 cents. At least check if that's possible. @dev team

                                  That's great to hear. I'll be looking forward to that. I'm playing around in Premiere Pro now trying to figure out how to remove the alpha channel from here. My understanding was that it had more to do with how it was packaged for download and didn't look feasible, but maybe I misunderstood that part.

                                    The issue with streaming passthrough videos via DLNA is finally fixed! At least on the Pico platform. Thanks to the team behind it..
