So yea there seems to be no end to small 360 cameras now coming out,
just wondering what are other peoples opinions on them any clear favourites or ones that stand out ?

Great explanation! Thanks. Could you elaborate a bit more about the following sentences:

Depth can be imagined if the camera is moving or if the light changes.

Do you man AS IF the camera is moving or ONLY IF the camera is moving?

One camera pointing straight up will allow to look all around and up but at some point below the horizon down will not be recorded.

Let's take an example. If I have the 360fly mounted on a helmet do you mean you can not see the lower part of my body, or do you mean you can not see the lower part of the end of let's say the room?

Two of these cameras can be mounted side by side to record stereo.

Side-by-side as in both the camera lenses pointing upwards, right?

The blind spot would be behind you. The amount of stereo diminishes to the left and right edges as the cameras would appear one behind the other from those placed instead of beside each other.

This is the part I still don't completely understand 🙂 .

Watching an interactive video in a HMD needs to have the movements of the camera anticipated by the viewer.

Again, let's take an example. If I have the 360fly mounted on a helmet and I walk down a stairs, what exactly should the viewer be anticipated for?

I mean there are other ways to see depth than having stereo images. Timelapse with the camera moving or dolly shots show depth better than a stationary camera.

One camera pointing straight up will allow to look all around and up but at some point below the horizon down will not be recorded.

Let's take an example. If I have the 360fly mounted on a helmet do you mean you can not see the lower part of my body, or do you mean you can not see the lower part of the end of let's say the room?

On the top of the helmet pointing up, it will see about 40° below the horizon, your body will not be in the shot.

Two of these cameras can be mounted side by side to record stereo.

Side-by-side as in both the camera lenses pointing upwards, right?

Side by side pointing forward. When shooting stereo you want the cameras to resemble eyes.

The blind spot would be behind you. The amount of stereo diminishes to the left and right edges as the cameras would appear one behind the other from those placed instead of beside each other.

This is the part I still don't completely understand 🙂 .

Imagine a pair of salt and pepper shakers sitting side by side. In front of the pair you can see both, and they can see you. move to the side and you can only see one. One is being obscured by the other. So only one can see you.
The distance they appear apart diminishes as you move to the side.

If they were two spherical cameras that could see all around by the time you got to the back the left and right eye would be reversed.

Watching an interactive video in a HMD needs to have the movements of the camera anticipated by the viewer.

Again, let's take an example. If I have the 360fly mounted on a helmet and I walk down a stairs, what exactly should the viewer be anticipated for?

If they are looking at your feet or there is some audio conversation going on, then no problem.
But if the camera is on someones head and they start dancing without any warning and bounce around, expect problems.

Nice! But maybe it's an idea to add some headings to your post 🙂 . Right now, it's one big chunk of text :mrgreen:

If I have time I will categorize the various camera's and links. I was thinking at:

1 - 2D
1.1 - Commercial
1.1.1 - For Sale
1.1.2 - Not (yet) for sale
1.2 - Non-commercial (scientific)

2 - 3D
2.1 - Commercial
2.1.1 - For Sale
2.1.2 - Not (yet) for sale
2.2 - Non-commercial (scientific)

Thanks for the updated list, but still no accessible S3D 360 camera solution.

Is there some kind of custom setup mentioned in the Japanse facebook group? I dont have Facebook so can't check it out for myself 🙂

Stereo 3d 360 degree video stitched from multiple cameras from my experience is difficult to achieve perfection. My findings are showing me that the stitching process needs to evolve a lot before stitch seams become unnoticeable in s3d.

In every video i've shot and every demo from others like JuantVR that use a camera array there is a noticeable seam. The issue steams from that when you stitch together the left eye and then the right eye, the seam blending for both eyes isn't perfectly matching for each eye. When you view s3d 360 one 1 eye independently you may not notice a seam, but when you view the stereo pair you do see a seam, from my findings this is a result of the blending engine and parallax from the cams. This seam appears as banding along the seam location.

I've also noticed that the 3d effect shooting with these very wide angle lenses is to me not very noticeable. As a result I've shifted my focus from stereo 3d 360 video to simply 360 video no 3d because of these issues. Any visual artifacting breaks the illusion and thus reduces immersion.

Maybe you can post some example videos you shot, so the experts here can indicate if your stitching can be improved.

Anyone can check out our youtube channel to see some of the 360 videos we've shot. Our videos are tests right now. I work professionally in the game industry and we are investigating new interactive story telling techniques with this new technology. This technology is so new and under developed that even the "experts" are not experts in this field.

Our test videos are not focused on creating perfectly smooth blended videos however we are achieving a high quality blend, currently we are focusing on what shots work and dont work, what makes you sick, what is boring and what is exciting, how do we move the camera, how do we hide the production team, what cuts work and dont work ect, and most importantly what experiences yield to be the most immersive.
