I'm trying to view this 3D SBS video on my mobile phone with a google cardboard VR headset.
The image does not split on my mobile, and is seen as a single widescreen image.
Does anyone know if a different sort of device is required to view this correctly?



UPDATE: It plays OK on an android phone, so it seems the problem was with my microsoft phone.
Please continue to read through the thread though!

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

A 3D effect can be achieved though.

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.



Artists must pass on, but sometimes a mix of passion, good fortune, diligence, expertise, and meticulous labor can capture and restore some of the beauty they left behind.

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:

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

Created with what claims to be a 2D to 3D image convertor, but I can't see much of a 3D effect here (although one side varies slightly from the other).

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

^This looks nice! The photo of Freddie doesn't work because both of the sides look to be taken from the same angle. your photo works perfectly well.

Thanks, I used an online converter for the Freddie image and I don't think it worked at all.
I really can't understand how a single 2D PHOTO can be made to look 3D anyway.
Have you come across any 2D to 3D image convertors that seem to work, even slightly?
I'm still looking.

Not really.
The first post you replied to concerned video, which can be manipulated to give a 3d effect (as already discussed).
There is also software out there which claims to do the same with a single 2d image, quite a different matter.
Are you saying the technology does not exist?

I'm saying it's not real 3D, unless it's made with the proper instruments. Taking a "2D" picture or video and turn it 3D with some trickery doesn't make it 3D. Simple as that. :D
