Synchronizing Your Tutorial with SMIL
file—called “slides.rp”—is a RealPix file. The contents of the RealPix file appears to the lower right. RealPix is a lot like SMIL; it’s a mark-up language that makes it easy to define transitions like fade-outs and wipes between your images. Notice that the RealPix file contains references to three images, for a total of six visual media files to be played with the audio file.
TIP: You may wish to create a skeletal SMIL or RealPix file that sequences your visual media without precise timing. Then listen to your audio track, note the times at which image transitions should occur and modify the SMIL file accordingly.
Real Networks maintains excellent documen- tation on producing multi-media presentations with SMIL and RealPix. Refer to thier support website (http://service.real.com/) for detailed help files and to learn about more sophisticated SMIL syntax.
