MacSHAPA (Penelope Sanderson)
(This project does not seem to be active, however Dr. Sanderson is happy to help users or inquirers "as resources allow.")
According to Justine Cassell, MIT Media Labs, MacSHAPA is a flexible video-annotation tool which supports user-defined coding schemes, has a shared-time line for all events, and comes with good search and statistical routines. And, it allows the user to output the data directly into a spreadsheet or SPSS, so that quantatative analyses can be done immediately.
MacSHAPA controls either high-end Panasonic or JVC VCRs, or it (v1.1) can work with Quicktime files.
