To protect against this you can run QuickTime in a separate process by enabling ‘protected player’ in Preferences. Protected playerĬertain media formats or codecs can occasionally cause stability problems with the built-in QuickTime player, so that playing a damaged media file could cause the CatDV application to abnormally terminate. When the QuickTime player is being used a blue ‘Q’ appears in the movie controller. It is possible to install extra QuickTime codecs and importers to support additional formats. This supports a wide number of file formats and codecs and supports import, transcoding, and editing functions as well as playback. The default playback mechanism that CatDV uses is based on the QuickTime library.
Which player is used depends on the file type and the options selected in Preferences (a coloured letter in the movie controller indicates which player is being used and you can click on the letter to jump to the appropriate section of preferences). There are many different formats of media file in existence and CatDV supports a number of different mechanisms for playing and working with these files.
