DraiKo Settings for Flat SBS 3D videos. The View Angle needs to be 180 and the Format is SBS. And the video file needs to be a Full-SBS 3D file. It should upload good, without admin help.
You may have actually got that information from me, haha. And unfortunately, it is not correct. A few months ago, I started messaging every DeoVR user I could find that had successfully uploaded a Flat 3D video file to DeoVR. One of them responded and said that he sets his videos as Video Type: SBS and View Angle: 180 and that he uploads full side-by-side 3D videos (not half side-by-side) So I relayed that info to support/Katya who may have relayed that info to you. But I have uploaded at least a dozen videos since then using those exact settings and they display properly 0% of the time. I think the few times I thought it worked (and the user I spoke to thought his worked) must have been due to a DeoVR moderator changing the settings after the video has processed, but before the video was published. So I thought those settings worked, but I was just unaware of DeoVR admins fixing them for me.
So to summarize, SBS and View Angle 180 does NOT work. And it makes sense why it wouldn't work - because those are the settings of a spherical VR180 video. Flat 2D and Flat 3D videos do not need a "View Angle".
