In the wake of adding an in-browser editor so users can edit video on the go, YouTube is now rolling out a beta feature that will allow you to convert your videos from 2D to 3D. Yeah, that's happening. YouTube, aware that 3D video is a thing and that hardly anyone has hardware capable of actually shooting it, decided that they might as well try their hand at 2D to 3D conversion, and although it's still in beta, it seems like it might be pretty legit.
In an attempt to make this feature as widely accessible as possible, YouTube is supporting pretty much every 3D option available, 3 colored-glasses options, interleaved, even cross-your-eyes side-by-side view. Unfortunately, I don't have the capability of testing anything except the cross-your-eyes version, but that seemed pretty alright despite the fact that it gives you a little bit of a headache by its very nature.
