Anvil: Annotation of Video and Language Data (Michael Kipp)
Anvil is a Java-based tool which permits multilayered annotation of video with gesture, posture, and discourse information. The tags used can be freely specified, and can easily be hierarchically arranged. Anvil requires the Java Media Framework, and should run on Solaris, Windows and (possibly) Linux. Video format is quicktime and AVI. Data storage and exchange is XML. It is freely available to the research community if you email the author.
