I have played a little with 3Denlive, and followed the discussion on the 3D Spider-Man.
I am not fully on grips of the application but I feel it is extremely interesting to produce videos out of a sequence of stereo images, including zoom-in/out effects, and overlaying two or more stereo images.
In my opinion 3Denlive as a video editor would work best if the input SBS images are already well aligned for the main angular parameters (visual axis rotation, h-perspective, v-perspective, and nominal focus correction). The only alignment parameter that makes sense for zooming in-out is the h-disparity (displacement in the X direction).
As an example of this take one stereo image that has a 3.3% horizontal disparity. If we make a video sequence that ends in 5x zoom-in, the disparity would become 16.5% which is obviously too much. This is were it makes sense to displace in the X direction trying to reduce the disparity in the zoomed-in area, or possibly masking some area of the image that creates excessive disparity.

Exactly !

As shown in this tutorial about how to use keyframes, you can control all alignment and placement/zoom parameters to make them adapted at each time position of the video.

http://3denlive.com/doc/EN/KeyframedAnimation.php

You are speaking about horizontal disparity. But, on some stereos, you may have a well-aligned whole image having some local deformations. When zooming on these details, you may need to completely re-align the zoomed sub-part. This is here where the "Automatic alignment" button takes a great part of its interest!

For example, in the Spider-Man case, you may have a well-align whole video, but it's very hard to get it properly with a well-aligned Spider-Man (in fact, the background seems to be a simple flat wall-paper!). You would certainly like to have a better alignment on it when zooming.

In the tutorial, see the first screen copy point 7, and third screen copy point 3 and 4.

Your explanations may be a bit confusing because there are two X tuning:

- the horizontal stereo shift in the Alignment configuration

- the horizontal position in the Placement configuration

In the same idea, there are two parameters that may change the size aspect:

- the horizontal and vertical adaptation in the Alignment configuration

- the zoom factor in the Placement configuration

;-)

Yes I have had one for quite a whie now.  I have found it to be fun and easy to use.  The only negative is the resolution which even though is 4K is stil distribirted over the eight lenses.

I have written a couple on artices on it for my club's newsletter, which you can finf in the drobox link.

Does anyone know of a dead-simple tool that will pull a 16:9 rectilinear SBS photo or video from a VR180/360 photo/video?

I would happily buy a ~$3500 Zcam K1 Pro if I could easily pull high-quality SBS 3D video from it instead of just VR180(which has some valuable but limited uses for me).

Nice shots in those Phereo albums! Thanks for sharing.

This IG account hasn't been active recently, but has some neat stereopair captures: http://www.instagram.com/stereoscopic_games/

Maybe a question for another thread, but have any Oculus Quest users had success with 3D screenshots?


The Destination, Not The Journey

 

It's the destination that's important, not the journey:
 
Live action 3D video captured with an AntVR 3D camera strapped on my head.
Audio recorded with a Tascam DR-05.
3D VR background captured with Oculus Link, Oculus Mirror and OBS.
Composited, edited and rendered with Vegas Pro.

> One concept is to use a simple design like the attached



The point in regards the One R is that it can use several lens pairs and especially the 1-inch Leica lens that is wide angle but not fish eye.  (By 1-inch, they mean 1-inch sensor) Also the left and right images are synched by the core module that is common to both lenses.

Sorry, I was referring to the Vuze XR - not the 360 camera.  That's because I got the Black Friday announcement in my inbox for the XR.

https://store.vuze.camera/buy/vuze-xr-dual-camera/

So then let me revise what I wrote above.  I definitely do not recommend the 360 model (either the original or the "+" (note that the sale is on the original model).  The IQ is not very good and the stitching between the pairs is horrible.  But at US$200., if you really feel like trying it out, that's up to you.  But the XR at US$299.00 is a much better choice although, as I said above, I'd just wait for the new crop of 3D 180 cameras coming in 2021.  They will not require a phone to adjust settings as all the above do.

I’ve looked at this before, but the $600 price tag was a barrier. At $200 it might well be worth a try.  Anyone had experience with this camera?

Yes, I have used that and it's good, as well as other ReVision AE plugins.
In particular Stereo Color Match is nice and I have used
Twixtor to make slow motion, or interpolate frames to improve sync errors
(works in some cases).  Many other effects too.  A bit $$.

If you know Mr. Jasmin, please get him/them to write a keyframed automatic 3D alignment tool :-).

Just a short play with the mask... having now a transparency parameter.

You can do that putting an image of that mask in a timeline above your image.

I think I can get the foreground/subject balancing you tell, by applying
a transparency factor on the crop mask, rather than having it fully
black. I will look to add this capability in 3De...

The good balancing in the image I submitted is there because STMANI3 found a good homography pair (even if I biased it) to apply to the entire images.

Independently, applying a fuzzy mask could be an interesting feature in 3De (and applying a custom-image/video mask could be interesting too by the way).
