I am interested in creating passthrough videos, but the current method of creating an alpha channel is not user-friendly at all. I can easily render out videos with an alpha channel built-in and ideally, DeoVR should be able to detect that alpha channel and display my video automatically in passthrough mode. Alternatively, allowing users to upload an alpha matte or luma matte file with ANY video will allow the video to play back with a background or in passthrough mode. Then the viewer can click a button on any video that has the included matte to view the video in passthrough.

The current DeoVR alpha solution seems to only work with fisheye lens videos and requires creating a matte in the red channel. This seems like an inefficient process when video codecs such as ProRes 4444 (with alpha) have existed for several years.

How can I enable Alpha Channel passthrough in the JSON file when running my own server? I tried changing the filename of the .mp4, but that doesn't work. I assume it must be done in the JSON definition. (I mostly need this for local testing)

pleasurant do you mean you want to run AI Passthrough for your videos on your DeoVR channel?

Hi. Any update on this? (enabling Alpha Channel pass-through on videos using JSON)

Not sure if this is what you are looking for, but to trigger deovr to recognize the content as having the alpha layer data in the corners, add _ALPHA to the filename. (source)

Thank you, but I'm trying to use Alpha passthrough when doing tests and post-production locally (own server). Like how you set up here: https://deovr.com/app/doc#single-video-deeplink

To clarify - this is for how to use Alpha when using the app to access videos on my own server (per the docs), without uploading to DeoVR.com.

As an example, I use JSON key/values such as "is3d":true, "screenType":"dome", "stereoMode":"sbs". I just don't know what to use to tell the player that Alpha mask is available.

Thanks!!

pleasurant hi, we will see to adding more instructions on how to do that to the documentation.
