Transana: Qualitative Analysis software for audio and video

Transana is an Open Source package to facilitate analyzing audio and video data. Here's what they say about it:

Transana is software for professional researchers who want to analyze digital video or audio data. Transana lets you analyze and manage your data in very sophisticated ways. Transcribe it, identify analytically interesting clips, assign keywords to clips, arrange and rearrange clips, create complex collections of interrelated clips, explore relationships between applied keywords, and share your analysis with colleagues. The result is a new way to focus on your data, and a new way to manage large collections of video and audio files and clips.

I haven't used it. The favored platform is Windows. It could be worth a look, though. Thanks to Charlie Gee for pointing this out.
