Just as a side note: What you've been uploading is not a 3d video but a 360° video. Those are two different things both of which are supported by the replay mod.
Are you sure that you used Equirectangular Rendering to render the video? Cubic Rendering for example is also 360° but can't be used as a 360° YouTube Video.
This will be an absolute Potato Quality. However, it should work.
To preempt mistakes while injecting metadata / rendering I would suggest calling your video 'video', save the injected File as 'video_metadata' and upload this one then. Just a little tip.
And how do I make VR then? Because I can't use the Cubik render method for yt but it seems possible. (I looked up the Docs it only says the Cubik Thing when I search for VR]

The video you linked is neither VR, there are time and keyframes that are interpolation. Additionaly, there is the 360° lookaround feature.
I mean, if I would pause both videos, and would WASD to tilt the camera etc in my video it does a camera roll, in crushedpixels video it changes the direction you are looking at to left if I would press D
