Hi, how do i set all photos on the timeline to the same duration?
Select (highlight) all the photos. Right-click on one of them. Click CHANGE DURATION. Under the preview window, set the new duration. <enter>
The default duration can be specified under OPTIONS|MEDIA.
And how to I set a default transition (including duration?)
Don't believe a default can be set, but the default duration is under OPTIONS|EDITING.
Why when i delete a photo does it delete a part of my sound track?
To protect an audio track, click the 'lock' at the left side of the track. The track will then appear shaded.
