How to stitch two video sources together ?

I'm using v15 Pro. Perhaps I am dreaming but........My goal is to film figure skating or hockey from two fixed camera positions (illustration) and then "stitch or splice" the video such that the customer (coaches) see one "big" widescreen - panoramic video. I know I can do this manually (sort of).

... really the goal is to find a way to show a large field of view in one video knowing that I need multiple cameras to capture the entire area. What would be the very best is to film from many positions and then have the software stich together into a 3D version ? I know...I'm dreaming :)

Comments or suggestions on the best way to accomplish this?

Hi,

Leave away the 3D for the moment that is a multicamera input naturally you have to import 2 or n movies and to place on time line, synchronise everything, cut and use picture in picture to display what you need. Your learning depend your knowledge and expert can tell you 2 or n cameras exactly same, a good sound (clap) to fix the start point, continous shoting to avoid to resynchronise. When time come to edit a good computer to handle many tracks at same time. VDL is good for this be patient a lot of work also sound is important

sr71,

Some thoughts...

The most successful stitched panoramas are shot from the same location (rotation about the lens to be technical), not a 15 or so meter blue line gap.

Given that commonly available technology is going to limit your coaches to a 'big' wide screen of 1920 x 1080 pixel full HD, Why not just shoot in very wide angle -- even fisheye -- and avoid any stitching?

As the 'normal' camera separation for 3D is about what's between your eyes you might get your 3D with a pair of fisheye cameras.

Big question... What do the coaches want to see? If they are going to analyse player movements then a 2D full rink shot from directly above would yield the best information. You seem to be heading for a spectacular 3D spectator perspective. I can remember some pretty lively arguments between spectators who 'saw' different things at a match!
