Panorama to video frames, II

About 8 months ago, I put up a PHP script that will split up a panorama into individual frames for reassembly to video (see thread "Extract frames from panorama" on this site).
I now have a further script that makes use of ImageMagick, available at psimagick.skeptic.de. This script will also do "barrel" and "3D" effects, as well as different sharpening levels, and different pixel increments/frame.
You can see what the resultant videos look like at my youtube channel (www.youtube.com/lctraynor), where the latest two (Paihia Sunset and Point Elizabeth Walkway) have barrel effects (the clouds are moving!).
Hope this is useful to someone.

Dear Michael,
The thread "Extract frames from Panorama" can be found in these forums. It was current until about 6 months ago. (Thread #72 from now, last reply: 10 Jul 2009 at 18:04).
What I do is:
Take a cylindrical panorama;
Extract an image from the lefthand side;
Then move through the panorama extracting successive images, each spaced by pixel/image increments;
This series of images (like film frames) is then assembled to AVI or MPEG format
So the process is not turning video into panoramas, but the other way around.
Please ask if you have any other questions.
Love Basel, have some cool friends there (at least, in Muttenz).
Latest video on youtube (see channel above) - Teide y Montana Blanca - has barreled and 3d (fisheye) distortions.
