Excerpt of article text...
Ever since the early days of REAL Software, QuickTime has been an important part of REALbasic. REALbasic 4.5 continues this tradition by updating QuickTime support with dozens of new features. Some of these items fill out previous features, while others provide completely new functionality. This article will step through some
of the major changes and improvements to help you get started with QuickTime
development in REALbasic 4.5.
EditableMovie
Perhaps the biggest change to QuickTime support in REALbasic 4.5 lies in the EditableMovie class, which is now a subclass of the Movie class. To create and save a movie in past versions of REALbasic, you might create a method named CreateMovie and add some code to it like in Code Listing #1.
This code creates an EditableMovie (e) at the location of the FolderItem (f). Then, it adds a new video track to the movie via the QTVideoTrack class. Finally, it adds sixty frames to the video track. Notice that there are no instructions to close or save the movie. That's because the EditableMovie's destructor took care of it for you.
