From the developer: "CatDV Pro is an essential logging and cataloging utility for video editors and everyone else who needs to manage a large number of media files. Video files are analysed and automatic scene detection is applied to automate the logging process. A thumbnail catalog is built up of all your clips, including an unlimited number of user-defined comment fields that you can search on to quickly find clips of interest. CatDV will also create and manage small preview movies that give you a compact record of your entire tape library even when the full resolution files are offline. Once you have idetified clips of interest, export a batch file or EDL to use these clips in your editing application.

"The Pro edition supports additional professional formats (including Pinnacle, Avid OMF, Final Cut pro), has enhanced search capabilities, and can work with an optional centralised relational database, whereas the Personal Edition provides a low cost single user version of the application."
