I shoot with the H3PRO10HD rig, which doesn't have a stitch template offered. This is such a young medium that there is little to no information out there yet, so I too was worried before I got the rig. But you don't need a stitching template because there is enough video overlap between all of the cameras.
Actually a stitch template isn't advised since AVP is stitching based on the video content itself. So instead of a square boxes fading together, it figures out the best region to slice and stitch together the videos. I've done many hours of shooting and never used a template. So rest at ease. you can actually test this yourself with the AVP demo and the demo datasets.http://www.autopano.net/wiki-en/action/ ... nchmarking
Something to consider is how all of these 360 rigs have parallax errors since the lens are not at the same point-of-origin. This is a constant battle to overcome. But it can be minimized as long as you don't get within 6-10 feet of the camera rig. Its even easier to fix if the camera rig is stationary.http://www.autopano.net/wiki-en/action/ ... -_Parallax
In chooseing a 3D rig, your stitch render load is going to be doubled. But your GPU setup will chow through that easily enough. You're also riding the tech bleeding edge, so you will have to experiment with 3D workflows on your own since very few are doing 360 video, let alone 360 3D video. Its a pretty big investment considering the yearly updates of the GoPro cameras. But it might be wise to get experience early too. Just some thoughts.
Render stats 8000x4000. (H3Pro10HD = 10 GoPro Hero3+ camera's recording at 2.7k resolution)
--- CPU: 0.05 render fps - taking about 12 hours to render 1m 30s of video.
--- GPU: 1.5 render fps - taking about 1 hour to render 1m 30s of video. (Nvidia GeForce GTX 770)http://www.autopano.net/wiki-en/action/ ... nchmarking
You might feel better about your decision after readign through the AVP Wiki, which really explains the whole process.http://www.autopano.net/wiki-en/Autopan ... umentation
