I'm viewing this 3D SBS video on my mobile phone with a google cardboard VR headset. Not much of a 3D effect though, and the aspect ratio is all wrong:

Unless it's filmed in 3D, you can't make it 3D.
You're welcome.

A 3D effect can be achieved though.

I'll going to try a little experiment on youtube.

Here's a SBS clip I created, comments welcome.

The entire point of stereoscopic photography is turning 2D into 3D. It has been done for almost 200 years.

The same techniques can be applied to video too.

The technique used for this video clip is quite different.
Stereoscopic cameras take more than one image at the same time, but from two different vantage points (one for each eye).
This clip was made from a 2D video and software was used to split and then basically shift one side vertically (amongst other things).
The result can never be as good as something that was actually filmed with a 3D camera to start with, but sometimes it can still be still look quite good.

Are you sure, because having one side show more horizontally (the right eye sees slightly more of the right side) and delayed by a frame or two is how this is usually done.
It tricks the eyes into thinking it's a slightly different angle and works brilliantly when the camera pans around things.

EdIt, Here's a frame grab, luckily Freddie moves his arms around so much that we can get a screenshot where the frame delay is noticable, and the sparkling background too.

Well I did say amongst other things, but you're right, the introduction of a delay does seem to be a key factor.
Just exactly what other "trickery" this particular software uses to mimick the result of a stereo camera is a bit of a mystery.
Like I said though, you can't beat a stereo camera to start with if you want the best results, this software can't produce angles that are just not there to begin with.
I also altered the aspect ratio on this clip, as you can see it's not quite right but there wasn't an option for the setting I wanted!
I will get it right with some practice, and perhaps different software.

PS. Did you watch the clip with a headset / viewer, if so what did you think?

Unfortunately I have no way to view it in 3d

You can do it without any device, by naked eyes. But it's much easier to do it on a smaller screen. I can easily do it on my phone.

You have to put your phone close to your eyes and look beyond it, like you're looking at the mountains, at the sky... Usually, it takes a while to master.

But this video is not the best to play with, which was mentioned by The Kurgan. Videos filmed in 3D from the beginning are always better. Try this:

It's called Crossed-Eyes Method

Take a look at this one with the naked eye, it looks much better with a viewer though.

I created this image of Freddie with what claims to be a 2D to 3D image converter.
It doesn't appear to have any 3D effect, and can't see how an image converter of this kind can possibly work anyway.

Quite pleased with my first attempt at taking a stereo photograph using my mobile phone and the shift method.
