Rig with different cameras

[maiko@haumaru.com]

Hi overthere,

I have a project in an immersion room  (10 meters by 6 meters) for a museum in Tahiti, French Polynesia.

1) To be able to have a good resolution for the front wall, I wanted to have a 6K+ resolution camera like a panasonic S1H+16-35mm or the GH5+7-14mm with latest firmware. And for the other walls (left, right and ground), just have 3 x gopro8. I made some camera rigs (see attached files) 

2) The other idea was to make a rig with the qoocam 8K  underneath a real camera (S1H or GH5) and replace the Qoocam video part concerned by the real camera by the video outputted by this latest.

As I am very novice in Mistika before going further with this idea, would it be easy to create a preset in Mistika to take in account the different cameras setup in 1 or 2 ?

If I understand a bit this article, this could work https://support.sgo.es/support/solutions/articles/1000262051-what-if-my-camera-rig-model-does-not-appear-in-the-camera-presets-list-

but can any of you can confirm ?

Regards,

Hi!

Thanks a lot for reaching out!

Of course, it may works. You could make a rig with different cameras, but, to be sure, the best way would be to test first the different rigs.

Please, create a new ticket in: https://support.sgo.es/support/solutions

You could send us a synchronized frame of each camera we could create the preset for that resolution but please try to send a scene that matches with the next. First, try to obtain a suitable scene for the calibration:

To create a preset for that rig, please do the following:

- Nothing and nobody close to the camera, at least 3 meters
- A street with buildings and trees, squares, parking lots
- Large halls, like sports venues, with a structured ceiling, with a camera in the open
- Public garage with no cars or columns at less than 3 meters

If a calibration shot cannot be obtained, choose the shot most fitting the above.

Optional, especially convenient for cameras with little overlap: Ask for a static scene, and two shots, second with the rig rotated half its camera spacing: Means if they are 4 cameras at the horizon at 90 degrees, rotate the rig 45 degrees. This provides an apparent doubling of a number of cameras and produces better lens distortion detection.

Notice that if a camera allows setting the image ratio at different values, like GoPro that can record both 4:3 and 16:9, settings for both resolutions may be needed. Recording a larger image is always better but some customers used a 16:9 ratio apparently.

I look forward to your answer!

 

Cheers!

Carlos

Thanks a lot for your reply.

Does it work if I activate stabilization on each camera (IS for the mirrorless and hypersmooth on gopros) or I should stabilize in postprod after stitching with mistika ?

Thanks

Any ideas ?

Yes you can do that. However, I recommend you first perform the stitching and later you stabilize it. That way first you focus on the stitching and then in the postpro effects. Actually you can use the stabilization feature inside Mistika VR, which processes the stabilization once the stitching is done.
