I would like to change the default duration of how long pictures are displayed and the duration of transition, so that every time I start Vidiowave they are set to 8.5 and 1.5 respectively. Currently I change default, but it for the current production only. Also can I set the default for the file path Proxy Files, I think this is a change to the registry.

In Videowave, which is the application to do the video editing, check File|Project Settings.
