How to connect stereoscopic video footage and sensors

by LondonBAM on Nov 16th, 2014 19:42 PM

Hi all,

I'm a videographer, journalist and artist and are interested in using this amazing technology for a project.

So here is my rough idea, project questions are following.

I want to record stereoscopic footage with two, lets say gopros, and be able to change the field of view during playback(dynamic cropped field of view from 180 degrees angle footage)

1. How difficult or easy is it to make the connection of two video sources(left & right eye) and a dynamic(controlled by phone sensors), cropped field of view from the the original footage?

2. Is anyone working on this already?

3. What are the requirements for the video footage? i.e. 2k, 4k, 1080p?

4. Are today phones capable of handling required amount of data?

5. Would it work with downsized or compressed footage?

6. Do you see any easy usable solution to question number 1?

i have spoke with the guy who created Cinema VR for Cmoar and he told me you have to change texture coord offset. if you make it work, please share with me: andregm3@hotmail.com

Just create an native plugin which utilizes the native android media class, create 2 invertes spheres, 2 materials, set texture offset/scale values, create 2 cameras, set them to render in SBS, set layer mask to let them render each on sphere, and tada, you got an basic 3D 360° video player

Hi all!!

Thank you very much for your thoughts on this!

To be honest I didn't understand a single word as I'm not into programming at all.

I'm looking for a very simple and affordable method to be able to record a video(left and right eye) with a super wide angle lens(nearly 180 degree). Then to crop the field of view for about 25% on all sides and then be able to control the movement of the field of view on the footage with the phone sensors. The vision does not have to be perfect but functionality should be reasonably.

I recorded a real live test video on Monday. Please feel free to have a look.

For this I used two gopro 3+ and shot it in 1080p at 48fps. I cropped off 25% left and right of each channel and positioned it accordingly. I tested it with an iPhone5 and google cardboard goggles and it worked surprisingly well.

An image of the camera set up I used is attached to this post.

For what I want to do at the moment a 180 degree field of view is absolutely sufficient. As this keeps the viewer engaged with what I need/want him to see. Also I don't want to build a second oculus rift and just want to utilize affordable and existing devices, like gopro's and smart-phones. If it works and I'm sure it's possible then it could develop into something really really great. Immersive journalism, art or a great and simple way to capture and replay our family holidays. There are so many possibilities! I think I still have to work on the way I have to record the footage. Maybe more distance to the subject and also higher resolution recordings(4K?) so it works better when cropped?

What do you think guys?
