This exports the presentation as QuickTime movie. The movie size and quality can be adjusted. There is also an option to include a browsable Table of Contents and captions.
The QuickTime movies produced are extremely small. To optimize file size and quality the audio is saved in the MPEG-4 format and the slides are saved as a picture track.
This will create a Table of Contents based on the slide titles. The Table of Contents will appear just to the right of the movie controller in Quicktime. This allows users to instantly jump to any slide in the movie.
This sets the video size to any number of predefined dimensions or a custom size. The video proportion will always be 4:3. It is not recommended to have images over 720 x 540. Images larger than this will be pixilated.
Because of the format LecShare Pro uses to create the movie, larger video dimensions create only a minimal increase in the file size.
This sets the quality of the video image.
Medium quality will be adequate for most uses.
This sets the quality of the audio. The audio is exported in the MPEG-4 format, so high quality audio can be achieved at very small file sizes. The highest quality (128 Kbs) will be very near to CD quality in most circumstances.
For voice recordings, medium quality (32 Kbs) will usually provide exceptional quality for the size.
This sets whether the audio will be exported in stereo or mono.
If the audio that is recorded or imported is in mono, the audio should be exported as mono. In this case exporting it as stereo will not increase the quality of the file and will cause the file size to increase significantly.
Quick Captions is a fast, convenient way to add captions to your QuickTime movie. Quick Captions will take the Lecturer's Notes from each slide and use them as a transcript to make captions for each slide. Read more about Quick Captions. You can choose to store the captions directly in the QuickTime movie or else have them play in a SMIL file.
SMIL (Synchronized Multimedia Integration Language) is a W3C standard for presenting multimedia presentations. It saves the video and audio as one combined file and the text captions as a separate file. Finally, it creates a .smil file (pronounced "smile file") which tells media players like QuickTime how to combine the two files. When a person loads the .smil file the media player will automatically load the necessary media files and synchronize them.
One advantage of the SMIL format is that it allows assistive technologies to have easy access to the captions of a movie.
LecShare Pro will automatically create an .htm file for use on a web server so the .smil file will play correctly in QuickTime.
