>DVI is no good for large collections of stills. The compression algorithm >relies on there being considerable commonality between successive images, >which is true of movies, but not of stills. The compression algorithm for stills is different. In fact, you can store stills at a variety of sizes by using no compression, various levels of compression, 9-bit or 16-bit storage format... On one still we worked with (768x480, 256 colors), file size varied between 188k (uncompressed) and 28k! Of course, the smaller file did not look as crisp. No doubleplusungoodcompanytalk here, as Orwell might say. Greetings from the Rocking Metropolis. JimF
