user6685: I want to build a camera rig with 3 canon 60d's to get some kind of panorama video. To verify my idea before building the real rig, I've implemented the setup in Blender  to test all possible cases:
 
Unfortunately I don't have much experience to stitch the images/videos correctly. How can I achieve that? Which software is suitable for that? How far the images of the cameras should overlap to get the best results? Besides the lens distortion, is there still something to consider?

user9105: From the ffmpeg docs
ffmpeg -i LEFT -i RIGHT -filter_complex framepack=sbs OUTPUT
framepack only works with 2 inputs, but you could merge 3 with a more complex filtergraph.  sbs means side-by-side.
This doesn't correct for perspective or handle the overlap or anything else needed for it to look good, and the word "panorama" doesn't appear in the ffmpeg docs.  If it's possible to do it properly with ffmpeg, it will require non-standard video filters.  (And by properly, I mean without manually finding how many pixels to crop from the inputs before feeding them to framepack).
Just posting in case people were wondering if ffmpeg did this.  Turns out the answer seems to be no.  It does have filters called "perspective" and "lenscorrection", but nothing for smart-stitching panoramas that I can see.
edit:
 After further questions from poor, I googled for ffmpeg panoramic, and found http://krpano.com/.  It says it can do panoramic video, but I'm not exactly sure WHAT it can do with it.  It doesn't list any video formats as input formats, but maybe it can work with image-per-frame PNGs or JPEGs or something.  Ok, no nvm, http://comments.gmane.org/gmane.comp.misc.ptx/24263 says krpano can play back / "explore" panoramic video.
The other google hits were from people trying to make a panoramic single image from multiple frames of a panning shot.
Hmm, this looks interesting.  Says it uses ffmpeg and pano tools.

Not sure it can actually stitch, though.  Might just correct fisheye->panorama.
Maybe this one:
https://groups.google.com/forum/#!topic/hugin-ptx/NroNAfQTz-8
mentions http://www.video-stitch.com/.  Commercial software with a free version that watermarks videos larger than 1024x768, but does have a download for Linux.  (presumably a statically linked x86 32bit binary.  It might use NVidia CUDA, at least on Windows.)

user9158: You could try if kolor works for you. It's not free but it's made for your exact needs. Check out the gallery for what they did. Or you can do it manually as Adam explains.

user11026: Here's a labor intensive solution.

Post if you have found another solution.
I have some 3 camera video panoramas from the 1980's I want to stitch.
thnks
