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.
