I would like to get hold of a digital movie that runs for about 30--60 seconds, with picture size 256*256 or 512*512, b&w or color. If you have such a movie, or if you know someone who can help, please do let me know. I need it for an academic, non-commercial purpose. In return for this favour I would be glad to keep the donor(s) informed of my research into new methods for the compression of static and moving pictures. These methods use a new tool for the time-frequency analysis of non-stationary signals -- the Frazier-Jawerth transform (FJT). The FJT is related to the Wavelet transform, and has a number of applications in engineering, physics, and mathematics.

There are many, many, many digital "movies" or animation sequences for the Amiga, many of which are demonstrations for software companies and are freely available (for free!). Assuming you are not using an Amiga (which is rather a shame...) you can transfer the movies to IBM, Mac, Atari disks using inexpensive software for the Amiga-it will read and write these disks with no problem. You could also transfer the movies by modem, although it would take a good little while! If you have no luck finding a dealer or users in your area, let me know, and I will try to find a local bulletin board for you. Paul

Someone suggested that the person who is looking for a digital movie consider using the numerous Amiga animation sequences which are available. While this seems like a good idea, I don't think that it is. The guy who was looking for a digital movie, was testing a compression algorithm. The animations that are available at places such as xanth.cs.odu.edu in directory amiga/demos are already in a compressed format. I am not talking about zoo or LZH compression, that only is for archival. The Amiga animations often employ a delta encoding inthe IFF picture as well as storing only the differences between frames of the animation. Since I am an Amigan, I naturally thought of my favorite machine, but then decided that the searcher would not find what he was looking for. I could provide a whole slew of 640x400 pictures of the Dr.Who logo moving around the screen. I just finished drawing it in DPaint II last night and was thinking of a neato animation of it and the Tardis. 8^) -- Bill Murphy murphy@newton.physics.purdue.edu
