There is also the possibility to join your movies with transitions. This might be useful if you want to add short clips and combine them to a bigger movie.
click on Transition at the Movie Editor (s. picture below) to set up the transition of your movies.
A little menu will open in which further settings of your transitions can be defined. The default value is No Transition (this should fit for most of the video DVDs). If you transitions between the videos just uncheck the mark in front of No Transition to get some.
Now you can choose your transition from a scrolling list on the left (s. picture below). A little preview screen at the right helps to select the best transition for your purpose. The duration of the transition can be defined with a little slider below. click on OK to proceed.
